    ABSTRACT: To reflect specific conditions in China, this study established a method to estimate landfill leachate amounts in two sources: infiltrated precipitation and water squeezed from waste. A hydraulic model (i. e. HELP) was used to obtain the precipitation infiltration factors for 31 typical Chinese cities. The calculation method for water squeezed from waste by compaction and degradation was set up based on theoretical analysis, and the key parameters-field capacity and degradation percentage-were acquired by literature mining. According to this method, landfill leachate quantities in 10 Chinese cities were calculated. Water squeezed from waste accounted for 52%~82% of the total leachate amounts during 40 years after landfilling, implying its importance in Chinese municipal landfills. Leachate generation amounts showed significant spatial variations due to the different precipitation infiltration factors and waste properties. Hence, leachate treatment measures should be selected according to its generation amounts rather than using certain general method. ©, 2015, Chinese Society for Environmental Sciences.

    ABSTRACT: Seven categories of odorous pollutants released from the collection and transportation process of municipal solid waste (MSW), including ammonia, sulfur compounds, terpenes, aromatics, alcohols, volatile fatty acids (VFAs) and carbonyls, were quantified through different analytical methods. Based on the field data, the compounds mainly causing malodour were assessed and identified. The cancer and non-cancer risk of odor exposure in the circumstance were corrsesponingly estimated by the health risk model. The uncertainties of risk value were estimated by Monte Carlo simulation. The concentration of odorous pollutants in the transfer station was one order of magnitude higher than that in the dust bin, which was closedly associated with the degradation of MSW. The concentration of alcohols increased stably with the extension of transportation chain, whereas the concentrations of VFAs and aromatics increased with fluctuation, and peaked in the bulk transfer station and in the container transfer station (131 μg/m3, 711 μg/m3 respectively). The major odorous compounds at the early stage of transportation were carbonyls, whereas at the end stage were sulfur compounds and VFAs.The adults' total cancer risk from odor pollution in the bulk transfer station was 2.64×10-5, whereas the total non-cancer risk was 3.01in the bulk transfer sstation and 1.22 in the container transfer station, which was closed to or exceeded the maximum acceptable risk levels recommended by US EPA. The risk values in the other transportation points were within the acceptable range. ©, 2015, Chinese Society for Environmental Sciences. All right reserved.

    ABSTRACT: Pre-hydrolysis of vegetable wastes was conducted with swill at different initial pH equal to 5, 6, 7, 8, and 9, and then the energy consumption of mechanical size reduction of raw and pre-hydrolysed vegetable wastes was studied. Experimental results showed that at initial pH equal to 7, 8 and 9, the energy consumptions of vegetable wastes after pre-hydrolysis were decreased from the original 0.304 J·g-1(wet basis) to 0.032, 0.025 and 0.027 J·g-1(wet basis), respectively, which declined by up to 90%; while those at initial pH equal to 5 and 6 slightly dropped to 0.200 and 0.219 J·g-1(wet basis). During the 8 h pre-hydrolysis at initial pH equal to 6, 7, 8 and 9, the pH and mass concentration of total organic carbon, volatile fatty acids and ammonia nitrogen in the liquid phase as well as the mass fraction of lignocellulose in the solid phase had little variations, indicating that the effect of biotic hydrolysis was not obvious. The swelling and moisture-absorbing and the structural change of celluloses under alkaline conditions, which can reduce the strength of lignocellulosic material, might be the main reasons for the decrease of energy consumption for mechanical size reduction.

    ABSTRACT: Treatment and utilization of liquid digestates from the anaerobic digestion of household kitchen waste (HKW) and restaurant food waste (RFW) require a better characterization of different cutting size fractions. Liquid digestates of HKW and RFW were fractionated by particle size into six fractions (1,000, 100, 3, 0.45, 0.1, 0.01 ìm). Each fraction was characterized for nutrient elements, organic matter, humus, metals, and salts because of the concern for the requirements for post-treatment and agricultural use. The results indicated that more than 87% of the N was linked with the 100-ìm cutting filtrate, over 90% of the K was dissolved, and over 70% of the P remained undissolved. In HKW and RFW liquid digestate, total organic carbon associated with the 0.1 to 100 ìm particulate accounted for 42% and 33%, respectively, whereas Ca associated with the 0.45 to 100 ìm particulate accounted for 75% and 60%, respectively. The nutrient elements, Fe, Mg, and salt content of RFW were higher than that of HKW. The concentrations of heavy metals in HKW and RFW digestate were extremely low. © 2015 American Society of Agricultural and Biological Engineers.

    ABSTRACT: The content and composition of hot water-soluble organic matters are important parameters for characterizing the bioavailability of organic matters in sludge. The pattern of hot water-soluble organic matters released from the waste activated sludge was investigated, and the effects of different water quenching time (1-24 h) and sludge concentration (0.7-36.0 g/L) on the release of proteins and carbohydrates were simultaneously evaluated. The released amounts of protein and carbohydrate reached their maximum values of 34.6% and 36.1% respectively, when the waste activated sludge was treated by water quenching at 60oC for 8 hours. However, with the further increase of the water quenching time, proteins were reduced into ammonia nitrogen, and the degradation of carbohydrate started as well. This led to reduction of the water-soluble protein and carbohydrate concentration. Considering the time efficiency of the test analysis and dissolution rate stability, the optimal water quenching time of the hot water-soluble organic matter was recommended to be set to 5 h. When treated with different sludge concentrations, lower initial sludge concentrations led to higher dissolution rate of hot water-soluble organic matters. When the initial sludge concentration was 0.7 g/L and water quenching for 5 h at 60oC, the percentages of protein and carbohydrate released arrived at 52.9% and 36.6% respectively, which was the maximum value from 0.7-36.0 g/L.

    ABSTRACT: Mesophilic anaerobic digestion (AD) on the feedstocks of household kitchen waste (HKW) and restaurant food waste (RFW) was performed. Five kinds of dewaterability indicators-total solids (TS), total solids after centrifugation (CTS), normalized capillary suction time (NCST), specific resistance to filtration (SRF) and bound water content (BW) were used to evaluate the dewaterability of digestate produced from different stages of AD. TS of digestate ranged from 3.0% to 9.9%, CTS ranged from 10.9% to 31.0%, SRF was 2.1×1013-13.8×1013 m·kg-1, BW was 2.3-15.1 g·(g TS)-1 and NCST was 50.8-163.7 s·L·(g TS)-1. The cumulative methane yield of the digester fed with RFW was always higher than the digester fed with HKW, maximum cumulative methane yield of the former was up to 381 ml·(g VSadded)-1, while that of the latter was just 280 ml·(g VSadded)-1. The dewatering performance of digestate was mainly affected by duration of anaerobic digestion and the digestate produced from RFW was able to achieve a higher dewatering degree, while the dewatering rate of the digestate from HKW was higher. Furthermore, there were significant correlations among TS, normalized CST, SRF and BW of digestate, but the correlation with CST was not significant.

    ABSTRACT: Impacts of Chlorella vulgaris with or without co-existing bacteria on the removal of nitrogen, phosphorus and organic matter from wastewaters were studied by comparing the wastewater treatment effects between an algae-bacteria consortium and a stand-alone algae system. In the algae-bacteria system, C.vulgaris played a dominant role in the removal of nitrogen and phosphorus, while bacteria removed most of the organic matter from the wastewater. When treating unsterilized wastewater, bacteria were found to inhibit the growth of algae at >231mg/L dissolved organic carbon (DOC). Using the algae-bacteria consortium resulted in the removal of 97% NH4(+), 98% phosphorus and 26% DOC at a total nitrogen (TN) level of 29-174mg/L. The reaction rate constant (k) values in sterilized and unsterilized wastewaters were 2.17 and 1.92mg NH4(+)-N/(mg algal cell ·d), respectively.

    ABSTRACT: In the present work, the humification level of waste-derived dissolved organic matter (DOM) at different waste biostability was investigated, by using fluorescent excitation-emission matrix (EEM) scanning. Different fluorescence spectrum analysis techniques were applied and compared. Experimental results demonstrate that parallel factor (PARAFAC) analysis was sensitive to reflect DOM humification, and the most reasonable to deconstruct DOM compositions, when compared with other spectrum analysis techniques. It suggests applying the DOM-EEM-PARAFAC pipeline for rapid estimation of waste biostability.

    ABSTRACT: The feasibility of cultivating Chlorella vulgaris with wastewater containing high ammonia nitrogen concentrations was examined. The average specific growth rate of C. vulgaris was 0.92d(-1) at 17mgL(-1) NH(4)(+)-N, but declined to 0.33d(-1) at NH(4)(+)-N concentrations of 39-143mgL(-1). At 39mgL(-1) NH(4)(+)-N, lipid productivity reached a maximum value (23.3mgL(-1)d(-1)) and dropped sharply at higher NH(4)(+)-N levels, which demonstrated NH(4)(+)-N should be controlled for biodiesel production. C16 and C18 fatty acids accounted for 80% of total fatty acids. Increasing NH(4)(+)-N from 17 to 207mgL(-1) yielded additional short-chain and saturated fatty acids. Protein content was in positive correlation with NH(4)(+)-N content from 17mgL(-1) (12%) to 207mgL(-1) (42%). Carbohydrate in the dried algae cell was in the range of 14-45%, with a peak value occurring at 143mgL(-1) NH(4)(+)-N. The results demonstrate that product quality can be manipulated by NH(4)(+)-N concentrations of the initial feeds.

    ABSTRACT: Upstream-operation-downstream (UOD) method was applied to study the greenhouse gas (GHG) emissions from one municipal solid waste (MSW) incineration plant in Shanghai. The contribution of each step and the influencing factors to GHG emissions were analyzed. The results showed that the incineration plant was source of GHG, which contributed 166~212 kg CO 2-eq/t of waste for incineration (fww). The fossil carbon content in the waste was found to be the critical factor, emitting 257 kg CO 2-eq/t fww. The utilization of electricity generated from incineration could save 120 kg CO 2-eq/t fww. Other parts (e.g. collection and transportation of wastes, disposal of bottom ash and fly ash and consumption of auxiliary material) released 27~45kg CO 2-eq/t fww. GHG emissions from leachate treatment were 7.7kg CO 2-eq/t fww. By saving of the auxiliary materials and changing of the disposal patterns of ashes, the GHG emissions can be mitigated in a limited degree. GHG savings varied by 0~13% when electricity factors in different regions were considered. In order to realize source-sink conversion of GHG for MSW incineration, the key approach was to increase the electricity generation capacity of the MSW by reducing water content.

    ABSTRACT: Distributions of extracellular enzymes, proteins (PN), and polysaccharides (PS) in the different extracellular polymeric substances (EPS) fractions of sludge flocs affect the wastewater treatment capability. The results showed that PN, PS, and extracellular enzyme had a distinct distribution pattern in the different EPS fractions. Both fourier transform infrared spectroscopy (FT-IR) and gel permeation chromatography (GPC) further suggested the difference of EPS fractions. These results suggest that by changing the distribution pattern of PN, PS, and extracellular enzyme, with some pretreatments before aerobic/anaerobic digestion, the performance of brewery wastewater treatment may be improved.

    ABSTRACT: To investigate the synergetic effect of pH and biochemical components on bacterial community structure during mesophilic anaerobic degradation of solid wastes with different origins, and under acidic or neutral conditions. The bacterial community in 16 samples of solid wastes with different biochemical compositions and origins was evaluated during mesophilic anaerobic degradation at acidic and neutral pH. Denaturing gradient gel electrophoresis (DGGE) and single-strand conformation polymorphism (SSCP) were used to compare the communities. Multivariate analysis of the DGGE and SSCP results revealed that most of the dominant microbes were dependent on the content of easily degradable carbohydrates in the samples. Furthermore, the dominant microbes were divided into two types, those that preferred an acid environment and those that preferred a neutral environment. A shift in pH was found to change their preference for medium substrates. Although most of the substrates with similar origin and biochemical composition had similar microbial diversity during fermentation, some microbes were found only in substrates with specific origins. For example, two microbes were only found in substrate that contained lignocellulose and animal protein without starch. These microbes were related to micro-organisms that are found in swine manure, as well as in other intestinal or oral niches. In addition, the distribution of fermentation products was less sensitive to the changes in pH and biochemical components than the microbial community. Bacterial diversity during anaerobic degradation of organic wastes was affected by both pH and biochemical components; however, pH exerted a greater effect. The results of this study reveal that control of pH may be an effective method to produce a stable bacterial community and relatively similar product distribution during anaerobic digestion of waste, regardless of variation in the waste feedstocks.

    ABSTRACT: The facilitated transport of dibutyl phthalate (DBP) and di(2-ethylhexyl) phthalate (DEHP), the priority endocrine disrupting chemicals in sludge, by dissolved humic substances (HS) was evaluated by batch extraction. The DBP, much less hydrophobic than DEHP, was inclined to migrate from sludge matrix into humic substances solutions, while the DEHP could not migrate facilitated by most humic and fulvic acids solutions, except the humic acid surrogate of high humification. This result revealed that the affinity of DEHP in sludge matrix exceeded DBP and was not susceptible by weak HS. The hydrophobic property controlled the association of phthalic acid esters on sludge residual phases. Migration rate of DBP was positively correlated to the weight-average molecular weight of HS surrogates and the aromatic extents of HA. Some functional groups in HS molecules benefited to the facilitated transport of DBP.

    ABSTRACT: Two trials were established to investigate the effect of recycled effluent on hydrolysis during anaerobic co-digestion of vegetable and flower waste. Trial I evaluated the effect by regulating the flow rate of recycled effluent, while Trial II regulated the ratio of hydrolytic effluent to methanogenic effluent, which were recycled to hydrolysis reactor. Results showed that the recirculation of methanogenic effluent could enhance the buffer capability and operation stability of hydrolysis reactor. Higher recycled flow rate was favourable for microbial anabolism and further promoted hydrolysis. After 9 days of hydrolysis, the cumulative SCOD in the hydrolytic effluent reached 334, 407, 413, 581 mg/g at recycled flow rates of 0.1, 0.5, 1.0, 2.0 m3/(m3 x d), respectively. It was feasible to recycling a mixture of hydrolytic and methanogenic effluent to the hydrolysis reactor. This research showed that partially introducing hydrolytic effluent into the recycled liquid could enhance hydrolysis, while excessive recirculation of hydrolytic effluent will inhibit the hydrolysis. The flow ratio 1:3 of hydrolytic to methanogenic effluent was found to provide the highest hydrolysis efficiency and degradation rate of lignocelluloses-type biomass, among four ratios of 0:1, 1:3, 1:1 and 3:1. Under this regime, after 9 days of hydrolysis, the cumulative TOC and TN in the hydrolytic effluent reached 162 mg/g and 15 mg/g, the removal efficiency of TS, VS, C and cellulose in the solid phase were 60.66%, 62.88%, 58.35% and 49.12%, respectively. The flow ratio affected fermentation pathways, i.e. lower ratio favoured propionic acid fermentation and the generation of lactic acid while higher ratio promoted butyric acid fermentation.

    ABSTRACT: Sewage sludge is of increasing concern in China, due to extended sewerage control and advanced wastewater treatments resulting from urbanization and economic growth. Based on the evolution of municipal sewage generation and treatment technologies in the last decade, as well as the long-term national and local plans in China, the paper elucidates production, distribution and characteristics (organics, nutrients, heat value, heavy metals, trace pollutants, pathogens) of sludge in some typical districts of China. The status and challenges of sludge management are discussed. INTRODUCTION In China, more than one thousand municipal wastewater treatment plants (WWTPs) will be put to operation in the next 10 years, most of which will adopt secondary or tertiary treatment processes. Increasing sewage treatment capacity and enhanced treatment processes will produce huge quantity of sewage sludge. Lee et al. (2006) reviewed the perspectives of sludge management in Beijing and Shanghai of China. This paper overviewed the current status of sludge management in China. SEWAGE AND SEWAGE SLUDGE In the past five years, the collected sewage in China increased in amount by 18.2%, while the sewage treatment capacity increased by 135%. At the end of 2005, 39% of the collected sewage was treated in WWTPs (Figure 1). A total of 792 sewage treatment plants located in 661 cities treated 57.25 million tons of wastewater per day (Figure 2). 87.4% of these WWTPs were operated with secondary or tertiary treatment processes. Up to June, 2005, 297 cities in China had no WWTPs for treating their sewage, indicating the potential growth of sewage treatment capability. Development in different regions of China is rather unbalanced, as evidenced by the implementations of big projects for sewage infrastructures in major provinces. The eastern regions of China have more WWTPs than the reminder area (Figure 3).

    ABSTRACT: Five batch testing scenarios were designed to evaluate the effects of alkali metal cations on anaerobic hydrolysis and acidogenesis. These scenarios were A (c=0 g l(-1)), B (cNa+=25 g l(-1)), C (cNa+=50 g l(-1)), D (cK+=25 g l(-1)), and E (cK+=50 g l(-1), pH 7.0). A solution pH of 7.0 or above favored protein hydrolysis, higher proteinase activity and higher ammonia production. However, such a pH suppressed carbohydrate hydrolysis, as indicated by low alpha-amylase activity. Cation interference at pH 5.0-6.0 seemed not to affect carbohydrate hydrolysis, as showed by the unimpaired alpha-amylase activity at 50 g l(-1) K+. Acidogenesis was more sensitive to alkali metal cations, so acid production and the drop in pH were lowest in a 25-50 g l(-1) Na+, acidic environment (pH 4.0-6.0). It was insensitive to cations when the pH was maintained at 7.0-8.0. When the pH was uncontrolled and decreased freely to acidic values, 25 g l(-1) of cation inhibited the action of the microbes, which rapidly acclimated, as presented by the slow transformation of soluble polymers to soluble metabolites. However, acidogenetic microbes could not easily recover from inhibition by 50 g l(-1) of cation. When the pH was maintained at over 7.0, the microbes were not inhibited by cation (50 g l(-1)) as indicated by the more active acidogenesis. The metabolic pathways to lactate, acetate and alcohols were not fully coupled.

    ABSTRACT: In 2010, the sewage sludge production rate will be 178,500 t dried solids (ds) for Beijing and 294,000 t-ds for Shanghai, respectively. Beijing adopts a centralized system to stabilize 78% of her sludge in three rural Stabilization Centres. Aerated composting technique will be used. Shanghai on the contrary decentralizes the management plan to treat the sludge on site. Diverse treatment trains, such as aerobic/anaerobic digestion, drying, incineration, and composting will be applied. Production rate, treatment plan, and the associated costs, energy consumption, carbon dioxide emission, and risk assessment for heavy metals and pathogens on human health were evaluated in this report for sludges yielded in Beijing and Shanghai, China.

    ABSTRACT: A three-compartment system, comprising a landfill column with fresh municipal solid waste, a column with a well-decomposed refuse layer as methane producer, and a sequential batch reactor as ex situ nitrifying reactor, was employed to remove nitrogen from municipal solid waste leachate. Since food waste comprised a major portion of refuse collected in Shanghai, an intense hydrolysis reaction occurred and caused the rapid accumulation of ammonia nitrogen (NH(3)-N) and total organic carbon in the leachate. This paper discusses the role of the three mentioned units and the design and operation of the proposed system. With most NH(3)-N being converted to nitrite nitrogen (NO(2)(-)-N) or nitrate nitrogen (NO(3)(-)-N) by the nitrifying reactor, and with the well-decomposed refuse layer transforming most dissolved organic compounds to CO(2), carbonates and methane, it was found that the fresh refuse column could efficiently denitrify the hydrolyzed nitrogen to N(2) gas. The role of the three mentioned units and comments on the design and operation of the proposed system are also discussed.

    ABSTRACT: The municipal solids waste (MSW) collected at Shanghai includes a high proportion of food waste, which is easily hydrolyzed to generate ammonia-nitrogen in leachate. This study investigated the efficiency of nitrogen removal from landfill leachate employing four different treatment processes. The simulated rainfall and direct leachate recycling produced strong leachate with high ammonia-nitrogen content, and resulted in the removal of only a small amount of nitrogen. Although pretreating the leachate using an aerobic reactor removed some nitrogen, most of which was transformed to biomass because of the high organic loading applied. Using the three-compartment system, which comprises a landfill column with fresh MSW, a column with well-decomposed refuse layer as the methane generator, and a nitrifier, the ammonia-nitrogen was converted into nitrogen gas and hence removed. Experimental results demonstrated the feasibility of adopting the three-compartment system for managing nitrogen in landfill leachate generated from high-nitrogen-content MSW.
