摘要

摘要: 新污染物(ECs)是具有生物毒性、环境持久性、生物累积性等特征的一类环境污染物,对生态环境或人体健康存在较大风险,并在我国城镇污水处理厂各工艺单元广泛检出。综述了我国城镇污水处理厂典型ECs特性,以及各工艺对ECs中药品及个人护理用品(PPCPs)和内分泌干扰物(EDCs)的去除效能。发现相比于国外污水排放和再生水ECs管控标准,我国的同类标准多集中在农药的管控上,缺少对PPCPs和EDCs的限制。PPCPs和EDCs 2类有机ECs在国内外污水厂中检出较多,污水厂一级处理工艺对PPCPs和EDCs的去除效率有限,生物处理能够较有效去除上述2类污染物,但还需深度处理工艺来实现完全去除。在此基础上提出了污水处理厂针对不同类别新污染物的去除工艺,并展望了未来污水厂去除ECs的工艺发展方向。

Abstract: Emerging contaminants (ECs) are a kind of environmental pollutants with characteristics of biotoxicity, environmental persistence, and bioaccumulation, which pose great risks to the ecological environment or human health, and are widely detected in the process units of wastewater treatment plants (WWTPs) in China. This review focuses on the characteristics of ECs in China’s WWTPs and the efficiency of each process to remove ECs. The results show that: compared with foreign standards for the control of new pollutants in WWTPs discharge and recycled water, China’s standards mostly focus on the control of pesticides, and lack restrictions on drugs and personal care products (PPCPs) and endocrine disruptors (EDCs); PPCPs and EDCs have been detected in many domestic and foreign WWTPs studies. The primary treatment process of WWTPs has limited removal efficiency of PPCPs and EDCs. Biological treatment can effectively remove the above two kinds of ECs, but it still needs an in-depth treatment process to achieve complete removal. On this basis, the removal processes for different types of ECs in WWTPs are proposed, and the future development of the process for removing ECs in WWTPs is prospected.
