Hecham OMAR, Sohrab ROHANI

《化学科学与工程前沿（英文）》 2015年 第9卷 第1期   页码 15-32 doi: 10.1007/s11705-015-1501-y

摘要： This review aims at the treatment of the entire landfill, including the waste mass and the harmful emissions: leachate and landfill gas. Different landfill treatments (aerobic, anaerobic and semi-aerobic bioreactor landfills, dry-tomb landfills), leachate treatments (anaerobic and aerobic treatments, anammox, adsorption, chemical oxidation, coagulation/flocculation and membrane processes) and landfill gas treatments (flaring, adsorption, absorption, permeation and cryogenic treatments) are reviewed. Available information and the gaps present in current knowledge is summarized. The most significant areas to expand are landfill waste treatments, which in recent years has begun to grow but there is an opportunity for much more. Another area to explore is the treatment of landfill gas, a very large field to which not much effort has been put forth. This review is to compare different treatment methods and give direction to future research.

Degradation of refractory organics in concentrated leachate by the Fenton process: Central composite

Senem Yazici Guvenc, Gamze Varank

《环境科学与工程前沿（英文）》 2021年 第15卷 第1期 doi: 10.1007/s11783-020-1294-1

摘要： Abstract • 90% total COD, 95.3% inert COD and 97.2% UV254 were removed. • High R2 values (over 95%) for all responses were obtained with CCD. • Operational cost was calculated to be 0.238 €/g CODremoved for total COD removal. • Fenton oxidation was highly-efficient method for inert COD removal. • BOD5/COD ratio of leachate concentrate raised from 0.04 to 0.4. The primary aim of this study is inert COD removal from leachate nanofiltration concentrate because of its high concentration of resistant organic pollutants. Within this framework, this study focuses on the treatability of leachate nanofiltration concentrate through Fenton oxidation and optimization of process parameters to reach the maximum pollutant removal by using response surface methodology (RSM). Initial pH, Fe2+ concentration, H2O2/Fe2+ molar ratio and oxidation time are selected as the independent variables, whereas total COD, color, inert COD and UV254 removal are selected as the responses. According to the ANOVA results, the R2 values of all responses are found to be over 95%. Under the optimum conditions determined by the model (pH: 3.99, Fe2+: 150 mmol/L, H2O2/Fe2+: 3.27 and oxidation time: 84.8 min), the maximum COD removal efficiency is determined as 91.4% by the model. The color, inert COD and UV254 removal efficiencies are determined to be 99.9%, 97.2% and 99.5%, respectively, by the model, whereas the total COD, color, inert COD and UV254 removal efficiencies are found respectively to be 90%, 96.5%, 95.3% and 97.2%, experimentally under the optimum operating conditions. The Fenton process improves the biodegradability of the leachate NF concentrate, increasing the BOD5/COD ratio from the value of 0.04 to the value of 0.4. The operational cost of the process is calculated to be 0.238 €/g CODremoved. The results indicate that the Fenton oxidation process is an efficient and economical technology in improvement of the biological degradability of leachate nanofiltration concentrate and in removal of resistant organic pollutants.

LOU Ziyang,CHAI Xiaoli,ZHAO Youcai,SONG Yu,ZHU Nanwen,JIA Jinping

《环境科学与工程前沿（英文）》 2014年 第8卷 第3期   页码 405-410 doi: 10.1007/s11783-013-0565-5

摘要： Variation and evolution process of leachate can be applied as a reference for landfill stabilization phase. In this work, leachates with different ages were collected from Laogang Refuse Landfill, and characterized with 14 key parameters. Simultaneously, principal component analysis (PCA) was applied to develop a synthetic parameter-F based on these 14 parameters, and a logarithm equation was simulated for the landfill stabilization process finally. It was predicted that leachates would meet Class I and Class II in standard for pollution control on the landfill site of municipal solid waste (GB 16889-1997) after 32 years and 22 years disposal under the natural attenuation in the humid and warm southern areas of China, respectively. The predication of landfill state would be more accurate and useful according to the synthetic parameter of leachate from a working landfill.

Wei LI, Xiaowen DING, Min LIU, Yuewen GUO, Lei LIU

《环境科学与工程前沿（英文）》 2012年 第6卷 第6期   页码 892-900 doi: 10.1007/s11783-012-0440-9

摘要： Chemical precipitation is a useful technology as a pretreatment to treat mature landfill leachate with high concentrations of ammonium-nitrogen ( ) and refractory organic compounds. Orthogonal experiments and factorial experiments were carried out to determine the optimal conditions enhancing the magnesium ammonium phosphate (MAP) precipitation process, and the experimental results demonstrated that the removal rate of was more than 85% when MgO and NaH PO ·2H O were applied as external sources of magnesium and phosphorous under the optimal conditions that molar ratio n(Mg)∶n(N)∶n(P) = 1.4∶1∶0.8, reaction time 60 min, original pH of leachate and settling time 30 min. In the precipitation process, pH could be maintained at the optimal range of 8–9.5 because MgO could release hydroxide ions to consume hydrogen ions. Calcium ions and carbonate ions existed in the leachate could affect the precipitation process, which resulted in the decrease of removal efficiency. The residues of MAP sediments decomposed by heating under alkaline conditions can be reused as the sources of phosphorous and magnesium for the removal of high concentrations of , and up to 90% of ammonium could be released under molar ratio of n[OH]∶n[MAP] = 2.5∶1, heating temperature 90°C and heating time 2h.

Anaerobic treatment of fresh leachate from a municipal solid waste incinerator by upflow blanket filter

Pinjing HE, Min LI, Suyun XU, Liming SHAO,

《环境科学与工程前沿（英文）》 2009年 第3卷 第4期   页码 404-411 doi: 10.1007/s11783-009-0149-6

摘要： This paper describes the feasibility of fresh leachate treatment by an upflow blanket filter (UBF). Through dilution and partial effluent recycling, the organic loading rates increased from 0.51to 14.56kg COD/(m·d), meanwhile the corresponding hydraulic retention time decreased from 9.0d to 3.6d. The reactor was able to achieve steady-state within 80d. Based on the distribution of COD fluxes in the process, it was concluded that anabolism was the main pathway of COD removal in the initial phase (1―33d), accounting for 57%―85% of total COD removed. As the anaerobic consortium of bacteria reached steady-state (after 70―86d), the majority of COD removed was transformed into methane, because the specific methane yield was close to the theoretical value (0.36L CH/(g COD)).

《环境科学与工程前沿（英文）》 2008年 第2卷 第1期   页码 24-31 doi: 10.1007/s11783-008-0024-x

摘要： Reverse osmosis system with the disc-tube module (DT-RO) was applied to treat landfill leachate on full scale at the Changshengqiao Sanitary Landfill, Chongqing City, China. In the first six-mouth operation phase, the treatment performance of DT-RO system had been excellent and stable. The removal rate of chemical oxygen demand (COD), total organic carbon (TOC), electrical conductivity (EC), and ammonia nitrogen (NH-N) reached 99.2–99.7%, 99.2%, 99.6%, and over 98%, respectively. The rejection of Ca, Ba, and Mg was over 99.9%, respectively. Suspended solid (SS) was not detected in product water. Effective methods had been adopted to control membrane fouling, of which chemical cleaning is of utmost importance to guarantee the long smooth operation of the DT-RO system. The DT-RO system is cleaned in turns with Cleaner A and Cleaner C. At present, the 1st stage cleaning cycle by Cleaner A and Cleaner C is conducted every 100 and 500 h, respectively, depending on raw the water quality.

Mechanism studies on nitrogen removal when treating ammonium-rich leachate by sequencing batch biofilm

XU Zhengyong, YANG Zhaohui, ZENG Guangming, XIAO Yong, DENG Jiuhua

《环境科学与工程前沿（英文）》 2007年 第1卷 第1期   页码 43-48 doi: 10.1007/s11783-007-0008-2

摘要： The nitrogen removal mechanism was studied and analyzed when treating the ammonium-rich landfill leachate by a set of sequencing batch biofilm reactors (SBBRs), which was designed independently. At the liquid temperature of (32?0.4)?C, and after a 58-days domestication period and a 33-days stabilization period, the efficiency of ammonium removal in the SBBR went up to 95%. Highly frequent intermittent aeration suppressed the activity of nitratebacteria, and also eliminated the influence on the activity of anaerobic ammonium oxidation (ANAMMOX) bacteria and nitritebacteria. This influence was caused by the accumulation of nitrous acid and the undulation of pH. During the aeration stage, the concentration of dissolved oxygen was controlled at 1.2 1.4 mg/L. The nitritebacteria became dominant and nitrite accumulated gradually. During the anoxic stage, along with the concentration debasement of the dissolved oxygen, ANAMMOX bacteria became dominant; then, the nitrite that was accumulated in the aeration stage was wiped off with ammonium simultaneously.

functional variations in the microbial community during the upgrade process of a full-scale landfill leachate

Binbin Sheng, Depeng Wang, Xianrong Liu, Guangxing Yang, Wu Zeng, Yiqing Yang, Fangang Meng

《环境科学与工程前沿（英文）》 2020年 第14卷 第6期 doi: 10.1007/s11783-020-1272-7

摘要： Abstract • Upgrade process was investigated in a full-scale landfill leachate treatment plant. • The optimization of DO can technically achieve the shift from CND to PND process. • Nitrosomonas was mainly responsible for ammonium oxidation in PND system. • An obviously enrichment of Thauera was found in the PND process. • Enhanced metabolic potentials on organics was found during the process update. Because of the low access to biodegradable organic substances used for denitrification, the partial nitrification-denitrification process has been considered as a low-cost, sustainable alternative for landfill leachate treatment. In this study, the process upgrade from conventional to partial nitrification-denitrification was comprehensively investigated in a full-scale landfill leachate treatment plant (LLTP). The partial nitrification-denitrification system was successfully achieved through the optimizing dissolved oxygen and the external carbon source, with effluent nitrogen concentrations lower than 150 mg/L. Moreover, the upgrading process facilitated the enrichment of Nitrosomonas (abundance increased from 0.4% to 3.3%), which was also evidenced by increased abundance of amoA/B/C genes carried by Nitrosomonas. Although Nitrospira (accounting for 0.1%–0.6%) was found to stably exist in the reactor tank, considerable nitrite accumulation occurred in the reactor (reaching 98.8 mg/L), indicating high-efficiency of the partial nitrification process. Moreover, the abundance of Thauera, the dominant denitrifying bacteria responsible for nitrite reduction, gradually increased from 0.60% to 5.52% during the upgrade process. This process caused great changes in the microbial community, inducing continuous succession of heterotrophic bacteria accompanied by enhanced metabolic potentials toward organic substances. The results obtained in this study advanced our understanding of the operation of a partial nitrification-denitrification system and provided a technical case for the upgrade of currently existing full-scale LLTPs.

《工程（英文）》 2024年 第37卷 第6期   页码 63-69 doi: 10.1016/j.eng.2024.02.008

摘要：

城市生活垃圾（MSW）是废塑料的重要归宿。在垃圾处置过程中，大塑料碎片会被分解成微塑料（MPs）并释放到渗滤液中。然而，现有研究仅关注垃圾填埋场渗滤液，其他类型渗滤液中MPs存在特征尚不清楚。因此，本研究分析了来自中国最大固体废物处置中心的垃圾填埋场渗滤液、干垃圾渗滤液和湿垃圾渗滤液三种类型渗滤液中MPs丰度及特征。结果表明，不同类型渗滤液中MPs平均丰度为（129 ± 54）到（1288 ± 184）particles·L−1，湿垃圾渗滤液中MPs丰度最高（p < 0.05）。不同类型渗滤液中聚合物类型具有差异，其中聚乙烯（PE）和碎片分别是所有渗滤液中主要的聚合物类型和形状。此外，条件破碎模型表明垃圾填埋过程对渗滤液中MPs的尺寸分布有较大影响，垃圾填埋场渗滤液中小尺寸MPs（20~100 μm）所占比例（> 80%）高于其他渗滤液。研究首次讨论不同类型渗滤液中MPs来源的研究，研究结果有助于MSW处置过程中MPs污染控制。

《化学科学与工程前沿（英文）》 2020年 第14卷 第4期   页码 673-687 doi: 10.1007/s11705-019-1800-9

摘要： Adsorptive polyethesulfone (PES) membranes were prepared by intercalation of powder activated carbon (PAC) with and without functionalization. Accordingly, PAC was aminated with 1,5-diamino-2-methylpentane, and the physicochemical properties of the functionalized PAC were analyzed. Intercalation of PAC within the PES scaffold changed the porosity and mean pore size of the aminated membrane (AC-NH ) from 52.6% to 92.5% and from 22.6 nm to 3.5 nm, respectively. The effect of temperature on the performance of the modified membranes was monitored by the flux and chemical oxygen demand (COD) removal of leachate. At ambient temperature, the COD removal of the neat, AC-containing, and AC-NH membranes was 47%, 52%, and 58.5%, respectively. A similar increment was obtained for the membrane flux, which was due to the synergistic effect of the high porosity and large number of hydrophilic functional groups. The experimental leachate adsorption data were analyzed by Langmuir, Freundlich, and Dubinin- Radushkevich isotherm models. For all membranes, the significant thermodynamic parameters ( , , and ) were calculated and compared. The isosteric heat of adsorption was lower than 80 kJ∙mol , indicating that the interaction between the membranes and the leachate is mainly physical, involving weak van der Waals forces.

《环境科学与工程前沿（英文）》 2012年 第6卷 第5期   页码 711-716 doi: 10.1007/s11783-012-0421-z

摘要： Considerable organic matter remains in municipal solid waste landfill leachate after biological treatments. Humic substances (HSs) dominate the organic matter in bio-treated landfill leachate. In this study, the HSs from landfill leachate treated by membrane bioreactor (MBR-HSs) were analyzed via elemental analysis, ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, and charge polarized magic-angle spinning- C-nuclear magnetic resonance. The characteristic absorption in the UV wavelength range indicated the presence of high C=C and C=O double bonds within the MBR-HSs. Compared with commercial HSs, MBR-HSs had lower carbon content [48.14% for fulvic acids (FA) and 49.52% for humic acids (HA)], higher nitrogen content (4.31% for FA and 6.16% for HA), lower aromatic structure content, and higher carbohydrate and carboxylic atoms of carbon content. FA predominantly had an aliphatic structure, and HA had less condensed or substituted aromatic ring structures than natural HA. The aromatic carbon content of MBR-HSs was lower than that of humus-derived HSs but higher than that of waste-derived HSs, indicating that MBR-HSs appeared to be more similar to humus-derived HSs than waste-derived HA.

Leaching characteristics of heavy metals during cement stabilization of fly ash from municipal solid waste incinerators

LIANG Shunwen, JIANG Jianguo, ZHANG Yan, XU Xin

《环境科学与工程前沿（英文）》 2008年 第2卷 第3期   页码 358-363 doi: 10.1007/s11783-008-0060-6

摘要： The leaching characteristics of heavy metals in products of cement stabilization of fly ash from a municipal solid waste incinerator were investigated in this paper. The stabilization of heavy metals such as Cd, Pb, Cu, and Zn in fly ash from such incinerators was examined through the national standard method in China based on the following factors: additive quantity of cement and NaS, curing time, and pH of leaching liquor. The results showed that as more additives were used, less heavy metals were leached except for Pb, which is sensitive to pH of the leachate, and the worse effect was observed for Cd. The mass ratio of cement to fly ash = 10% is the most appropriate parameter according to the national standard method. When the hydration of cement was basically finished, stabilization of heavy metals did not vary after curing for 1 d. The mixtures of cement and fly ash had excellent adaptability to environmental pH. The pH of leachate was maintained at 7 when pH of leaching liquor varied from 3 to 11.

《工程（英文）》 2024年 第34卷 第3期   页码 120-132 doi: 10.1016/j.eng.2023.03.005

摘要：

循环经济背景下，剩余污泥生物质能源的可持续回收利用引发广泛关注。本研究提出了一种基于游离亚硝酸（FNA）的创新生物技术，通过耦合短程硝化、发酵和反硝化过程（PN/DN–F/DN）不仅完成剩余活性污泥（WAS）废弃生物质能源回收利用，同时驱动晚期垃圾渗滤液深度脱氮。首先，晚期垃圾渗滤液氨氮[(1708.5 ± 142.9) mg·L−1]在短程硝化耦合反硝化序批式反应器（PN/DN-SBR）好氧段被氧化为亚硝态氮，亚硝态氮累积率高达95.4%±2.5%。PN/DN-SBR出水[NO2−–N = (1196.9 ± 84.2) mg·L−1]与外源浓缩剩余活性污泥[挥发性固体浓度= (15119.8±2484.2) mg·L−1]共同泵送至缺氧反应器，用于发酵耦合反硝化（F/DN-SBR）。游离亚硝酸作为亚硝态氮的质子化形式，通过强烈的生物抑制作用将污泥有机质转化为高品质碳源，被反硝化细菌捕获利用，进而推动氮氧化物的还原过程。该创新技术实现了 4.89 kg·m−3·d−1超高污泥减量速率和 0.46 kg·m−3·d−1 脱氮速率。最后，富含有机物的 F/DN-SBR 出水回流至 PN/DN-SBR 后置缺氧阶段进行二次反硝化脱氮。PN/DN-F/DN系统连续运行 175 天后，每个运行周期平均回收 19350.6 mg 有机物（以COD计），脱氮效率为 95.2%，污泥减量率为 53.4%。以等效能源总量计算，每处理1吨剩余污泥可产生291.8 kW·h当量能源，对促进污水处理领域从能源消耗到能源中和模式的范式转变具有重要意义。
