Polder is a type of irrigation field unique to the lower Yangtze River of China. It is a product of long-term and ingenuous human modifications of wetland landscapes. In the pre-Qin Period, 3000 years ago, the poldered area of eastern Wuhu city was once a large lake called the ancient Danyang wetland. The introduction of agricultural civilization and polder technology to the area during the Wu and Yue Kingdoms period gradually transformed it into an agricultural area. With an accelerating rate of land reclamation under a changing late-Holocene regional climate, the ancient Danyang wetland became an aquatic system strongly influenced by intensifying anthropogenic activities. In this study, based on field survey data, historical documents, and remote-sensing and archaeological data, we reconstructed the spatial distribution of the polder landscape over the last 3000 years and identified their structural diversity. We found that polder landscapes began to emerge in the Spring and Autumn Period, land reclamation intensified in the Three Kingdoms and developed rapidly in the Song Dynasty before eventually reaching the peak from the Ming and Qing *** relocation of historical sites to low-altitude areas also marked the expansion of poldered fields from the center of the wetland to the southeast and northwest. The development and evolution of the polder landscape are related to regional climate conditions, changing social and economic statuses, and the development of agricultural technology in the Song Dynasty and succeeding periods.

抗生素的广泛使用使得耐药和泛耐药病原菌不断涌现,对全球公共卫生造成了巨大威胁。目前,噬菌体治疗已成为抗击多重耐药菌的重要手段之一,在欧美国家和中国已经进行了临床应用。然而,中国目前尚未形成针对噬菌体治疗的专项监管法规,研究者发起的临床研究成为我国开展噬菌体治疗的主要形式,这制约了我国噬菌体治疗的进一步发展和广泛应用,亟需在当前的药品监管框架下,制定适当的噬菌体监管法规。因此,本文回顾了格鲁吉亚、美国、英国、比利时和中国的噬菌体治疗现状和监管法规框架,旨在为噬菌体临床治疗的监管提供参考。完善的噬菌体临床应用监管法规将极大促进噬菌体治疗在中国的推广和应用,也必将有效地遏制细菌耐药危机,更好地维护人民群众的生命健康安全。

Coking wastewater treatment for industrial reuse purpose: Combining biological processes with ultrafiltration, nanofiltration and reverse osmosis

引用

Journal of Environmental Sciences 2013年第8期25卷 1565-1574页

作者： Xuewen Jin Enchao Li shuguang lu Zhaofu Qiu Qian Sui State Environmental Protection Key Laboratory of Environmental Risk Assessment and Control on Chemical Process East China University of Science and Technology Shanghai Baosteel Chemical Co. Ltd.

A full-scale plant using anaerobic, anoxic and oxic processes （A1/A2/O）, along with a pilot-scale membrane bioreactor （MBR）, nanofiltration （NF） and reverse osmosis （RO） integrated system developed by Shanghai Baosteel Chemical Co. Ltd., was investigated to treat coking wastewater for industrial reuse over a period of one year. The removals reached 82.5% （COD）, 89.6% （BOD）, 99.8% （ammonium nitrogen）, 99.9% （phenol）, 44.6% （total cyanide （T-CN））, 99.7% （thiocyanide （SCN-）） and 8.9% （fluoride）, during the A1/A2/O biological treatment stage, and all parameters were further reduced by over 96.0%, except for fluoride （86.4%）, in the final discharge effluent from the currently operating plant. The pilot-scale MBR process reduced the turbidity to less than 0.65 NTU, and most of the toxic organic compounds were degraded or intercepted by the A1/A2/O followed MBR processes. In addition, parameters including COD, T-CN, total nitrogen, fluoride, chloride ion, hardness and conductivity were significantly reduced by the NF-RO system to a level suitable for industrial reuse, with a total water production ratio of 70.7%. However, the concentrates from the NF and RO units were highly polluted and should be disposed of properly or further treated before being discharged.

Recent advances in pharmaceuticals and personal care products in the surface water and sediments in China

Frontiers of Environmental Science & Engineering 2016年第6期10卷 29-40页

Pharmaceuticals and personal care products （PPCPs） have been regarded as an emerging problem in the surface water environment in the past few decades. In China, although related studies were initiated several years ago, an increasing number of studies on this topic have been conducted in recent years. These studies have expanded knowledge of their occurrence, behavior and associated risk in the surface water environment in China. This review compiles the most recent literature related to the studies of PPCPs in the surface water environment in China. It includes PPCP occurrence in surface water and sediments, their geographical distribution, and outcomes of the associated risk assessment. It shows that antibiotics have received much more attention in both surface water and sediments than other PPCPs. Compared to other countries; most antibiotics in the collected sediments in China showed higher contamination levels. Many more study areas have been covered in recent years; however, attention has been given to only specific areas. Environmental risk assessment based on risk quotients indicated that sulfamethoxazole presents the most significant environmental risk to relevant aquatic organisms; followed by ofloxacin, ciprofloxacin, enrofloxacin, 17α-ethynylestradiol, ibuprofen and diclofenac. Despite limited research on the environmental risk assessment of PPCPs in sediments, higher risks posed by PPCPs in the sediments rather than surfhce water were identified highlighting the need for further risk assessment of PPCPs in sediment samples.

Enhanced reductive degradation of carbon tetrachloride by carbon dioxide radical anion-based sodium percarbonate/ Fe（ll）/formic acid system in aqueous solution

引用

Frontiers of Environmental Science & Engineering 2018年第2期12卷 61-70页

作者： Wenchao Jiang Ping Tang shuguang lu Xiang Zhang Zhaofu Qiu Qian Sui State Environmental Protection Key Laboratory of Environmental Risk Assessment and Control on Chemical Process East China University of Science and Technology Shanghai 200237 China

The performance of sodium percarbonate （SPC） activated with ferrous ion （Fe（Ⅱ） with the addition of formic acid （FA） to stimulate the degradation of carbon tetrachloride （CT） was investigated. Results showed that CT could be entirely reduced within 15 min in the system at a variety of SPC/Fe（Ⅱ）/FA/CT molar ratios in experimental level. Scavenging tests indicated that carbon dioxide radical anion （CO2-） was the dominant reactive oxygen species responsible for CT degradation. CT degradation rate, to a large extent, increased with increasing dosages of chemical agents and the optimal molar ratio of SPC/Fe（Ⅱ）/FAJCT was set as 60/60/60/1. The initial concentration of CT can hardly affect the CT removal, while CT degradation was favorable in the pH range of 3.0-9.0, but apparently inhibited at pH 12. C1- and HCO3 of high concentration showed negative impact on CT removal. Cl- released from CT was detected and the results confirmed nearly complete mineralization ofCT. CT degradation was proposed by reductive C-C1 bond splitting. This study demonstrated that SPC activated with Fe（Ⅱ） with the addition of FA may be promising technique for CT remediation in contaminated groundwater.

Effect of effluent organic matter on ozonation of bezafibrate

Frontiers of Environmental Science & Engineering 2015年第6期9卷 962-969页

作者： Huan HE Qian SUI shuguang lu Wentao ZHAO Zhaofu QIU Gang YU State Environmental Protection Key Laboratory of Environmental Risk Assessment and Control on Chemical Process School of Resources and Environmental Engineering East China University of Science and Technology Shanghai 200237 China State Key Laboratory of Pollution Control and Resource Reuse College of Environmental Science and Engineering Tongji University Shanghai 200092 China School of Environment THU - VEOLIA Joint Research Center for Advanced Environmental Technology Tsinghua University Beijing 100084 China

The influence of three effluent organic matter （EfOM） model compounds, humic acid （HA）, bovine serum albumin （BSA）, and sodium alginate （AGS）, on the ozonation ofbezafibrate （BF）, a typical pharmaceutical and personal care product （PPCP）, was investigated. The results show that ozonation efficiently removed BF from aqueous solution with removal efficiencies 〉 95% within 8 min for all conditions. The reaction rate of BF decreased with increasing model compounds concentrations and the influence was more pronounced for HA and BSA, while less pronounced for AGS. Although BF concentration was significantly reduced, the degree of mineralization achieved was only approximately 11%. The addition of HA and BSA improved the mineralization of the solution, while the influence of AGS was minor. The acute toxicity of BF solution during ozonation was determined using the luminescent bacteria test, and the toxicity exhibited an initial increase and a successive reduction. An overall decreased acute toxicity was observed with an increase of HA. The presence of BSA increased the formation rate of toxicity intermediates and resulted in inhibition peak forward.
