Industrial water treatment and industrial marine outfalls: Achieving the right balance

Adrian W. K. Law,Chunyan Tang

《化学科学与工程前沿（英文）》 2016年 第10卷 第4期   页码 472-479 doi: 10.1007/s11705-016-1592-0

摘要： Industrial water treatment and industrial marine outfalls both function together to reduce the pollutant concentrations in the effluent and mitigate the potential impact on the environment. The former uses environmental treatment technology with energy and material cost considerations, while the latter utilizes the natural assimilation potential of the coastal water environment achievable at the outfall location. Because of their synergistic nature, marine outfalls are now commonly used for the disposal of partially treated domestic and industrial effluents in many coastal cities around the world, with many successful examples of low and acceptable risks to the environment. The objective of this paper is to review their balance from both environmental and economic considerations. We also discuss the end-of-the-pipe and mixing zone approaches for industrial effluents, and give some recommendations particularly for developing countries. Finally, we emphasize that a compulsory and vigorous monitoring program is essential regardless of how the balance is achieved.

Dissolved methane in anaerobic effluent: Emission or recovery?

《环境科学与工程前沿（英文）》 2022年 第16卷 第4期 doi: 10.1007/s11783-022-1537-4

摘要： Various anaerobic processes have been explored for the energy-efficient treatment of municipal wastewater. However, dissolved methane in anaerobic effluent appears to be a barrier towards the energy and carbon neutrality of wastewater treatment. Although several dissolved methane recovery methods have been developed, their engineering feasibility and economic viability have not yet been assessed in a holistic manner. In this perspective, we thus intend to offer additional insights into the cost-benefit of dissolved methane recovery against its emission.

Optimization of thermophilic anaerobic-aerobic treatment system for Palm Oil Mill Effluent (POME)

Yijing CHAN,Meifong CHONG,Chunglim LAW

《环境科学与工程前沿（英文）》 2015年 第9卷 第2期   页码 334-351 doi: 10.1007/s11783-014-0626-4

摘要： Optimization of an integrated anaerobic-aerobic bioreactor (IAAB) treatment system for the reduction of organic matter (Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS) concentrations) in Palm Oil Mill Effluent (POME) to legal standards with high methane yield was performed for the first time under thermophilic condition (50°C–55°C) by using response surface methodology (RSM). The experiments were conducted based on a central composite rotatable design (CCRD) with three independent operating variables, organic loading rates in anaerobic compartment (OLR ) and mixed liquor volatile suspended solids (MLVSS) concentration in anaerobic (MLVSS ) and aerobic compartments (MLVSS ). The optimum conditions for the POME treatment were determined as OLR of 15.6 g COD·L ·d , MLVSS of 43100 mg·L , and MLVSS of 18600 mg·L , where high aerobic COD, BOD and TSS removal efficiencies of 96.3%, 97.9%, and 98.5% were achieved with treated BOD of 56 mg·L and TSS of 28 mg·L meeting the discharge standard. This optimization study successfully achieved a reduction of 42% in the BOD concentrations of the final treated effluent at a 48% higher OLR as compared to the previous works. Besides, thermophilic IAAB system scores better feasibility and higher effectiveness as compared to the optimized mesophilic system. This is due to its higher ability to handle high OLR with higher overall treatment efficiencies (more than 99.6%), methane yield (0.31 L CH ·g COD ) and purity of methane (67.5%). Hence, these advantages ascertain the applicability of thermophilic IAAB in the POME treatment or even in other high-strength wastewaters treatment.

Unintended nutrient imbalance induced by wastewater effluent inputs to receiving water and its ecological

《环境科学与工程前沿（英文）》 2022年 第16卷 第11期 doi: 10.1007/s11783-022-1584-x

摘要： Eutrophication is the most widespread water quality issue globally. To date, most efforts to control eutrophication have focused on reductions of external nutrient inputs, yet importance of nutrient stoichiometry and subsequent shift in plankton composition in aquatic ecosystem has been largely neglected. To address eutrophication, improved sanitation is one of the United Nations Sustainable Development Goals, spurring the constructions of wastewater treatment facilities that have improved water quality in many lakes and rivers. However, control measures are often targeted at and effective in removing a single nutrient from sewage and thus are less effective in removing the others, resulting in the changes of nutrient stoichiometry. In general, more effective phosphorus removal relative to nitrogen has occurred in wastewater treatment leading to substantial increases in N/P ratios in effluent relative to the influent. Unfortunately, high N/P ratios in receiving waters can impose negative influences on ecosystems. Thus, long-term strategies for domestic wastewater management should not merely focus on the total reduction of nutrient discharge but also consider their stoichiometric balances in receiving waters.

Identifying human-induced influence on microbial community: A comparative study in the effluent-receiving

Yuhan Zheng, Zhiguo Su, Tianjiao Dai, Feifei Li, Bei Huang, Qinglin Mu, Chuanping Feng, Donghui Wen

《环境科学与工程前沿（英文）》 2019年 第13卷 第6期 doi: 10.1007/s11783-019-1174-8

摘要： Microbial compositions showed high differences in two study areas. COD was the key anthropogenic indicator in the coastal wastewater disposal area. Distinctive microbes capable of degrading toxic pollutants were screened. Microbial communities in effluent-receiving areas followed “niche theory”. Microbial community structure is affected by both natural processes and human activities. In coastal area, anthropegenetic activity can usually lead to the discharge of the effluent from wastewater treatment plant (WWTP) to sea, and thus the water quality chronically turns worse and marine ecosystem becomes unhealthy. Microorganisms play key roles in pollutants degradation and ecological restoration; however, there are few studies about how the WWTP effluent disposal influences coastal microbial communities. In this study, sediment samples were collected from two WWTP effluent-receiving areas (abbreviated as JX and SY) in Hangzhou Bay. First, based on the high-throughput sequencing of 16S rRNA gene, microbial community structure was analyzed. Secondly, several statistical analyses were conducted to reveal the microbial community characteristics in response to the effluent disposal. Using PCoA, the significant difference of in microbial community structure was determined between JX and SY; using RDA, water COD and temperature, and sediment available phosphate and ammonia nitrogen were identified as the key environmental factors for the community difference; using LDA effect size analysis, the most distinctive microbes were found and their correlations with environmental factors were investigated; and according to detrended beta-nearest-taxon-index, the sediment microbial communities were found to follow “niche theory”. An interesting and important finding was that in SY that received more and toxic COD, many distinctive microbes were related to the groups that were capable of degrading toxic organic pollutants. This study provides a clear illustration of eco-environmental deterioration under the long-term human pressure from the view of microbial ecology.

摘要： Since the introduction of the membrane bioreactor (MBR) in China in the early 1990s, remarkable progress has been achieved on the research and application of this technology. China has now become one of the most active fields in the world in this regard. This review outlines the development of MBR-based processes in China and their performance of treating municipal and industrial wastewaters. Since membrane fouling is a critical operational problem with MBR processes, this paper also proposes updated understanding of fouling mechanisms and strategies of fouling control, which are mainly compiled from publications of Chinese researchers. As for the commercial application of MBR in the country, the latest statistics of large-scale MBR plants (>10000 m·d) are provided, and the growth trend of total treatment capacity as well as its driving force is analyzed.

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)).

摘要： For effective wastewater reclamation and water recovery, the treatment of natural and effluent organic matters (NOM and EfOM), toxic anions, and micropollutants was considered in this work. Two different NOM (humic acid of the Suwannee River, and NOM of US and Youngsan River, Korea), and one EfOM from the Damyang wastewater treatment plant, Korea, were selected for investigating the removal efficiencies of tight nanofiltration (NF) and ultrafiltration (UF) membranes with different properties. Nitrate, bromate, and perchlorate were selected as target toxic anions due to their well known high toxicities. Tri-(2-chloroethyl)-phosphate (TCEP), oxybenzone, and caffeine, due to their different and p values, were selected as target micropollutants. As expected, the NF membranes provided high removal efficiencies in terms of all the tested contaminants, and the UF membrane provided fairly high removal efficiencies for anions (except for nitrate) and the relatively hydrophobic micropollutant, oxybenzon

A pilot scale test of ozonization treatment of ethene wastewater for reuse

ZHONG Li, REN Wei, GUO Wenjing

《化学科学与工程前沿（英文）》 2008年 第2卷 第2期   页码 191-195 doi: 10.1007/s11705-008-0028-x

摘要： A pilot scale test of advanced treatment of ethene wastewater by ozonization was carried out for industrial water reuse. Effects of different operating conditions on COD degradation, such as wastewater flow rate, ozonized gas flow rate, operating voltage of ozonizer and two ozone generation means, using pure oxygen or air, was investigated. The results show that the increase of ozonizer operating voltage, the decrease of wastewater flow rate and the suitable ozonized gas flow rate improve the removal of COD in wastewater and that ozone generated respectively from air and pure oxygen can effectively remove COD of ethene wastewater to meet the industrial water reuse criterion.
