【摘要】 城镇污水处理厂尾水作为城市受纳水体的潜在污染源,对城市水环境的影响不容忽视。在当前面临水环境治理挑战的前提下,对污水处理厂尾水排入城市水体后造成的影响进行系统性研究,对改善尾水排放对受纳水体的作用具有重要意义。文章介绍了我国污水处理厂尾水和城市水环境的现状,综述了国内外污水处理厂尾水排放对城市水环境影响的研究,主要介绍了尾水排放对下游水体营养盐负荷和底栖微生物群落及功能菌的影响,以及水质水动力模型在该研究方向的应用,并根据国内外该领域的研究现状提出了后续需要进行深入研究的方向。更多还原

【Abstract】 As a potential pollution source of urban receiving water, the impact of effluent from wastewater treatment plant(WWTP) on aquatic environment should not be ignored. The overall research on the influence of WWTP tail water on urban rivers is of great significance to the protection of urban water environment. The paper presented the current situation of WWTP effluent and urban water environment in China, and elaborated the research on the influence of effluent on the water home and abroad, mainly concerning nutrient loads and hydrodynamic model as well as benthic microbial community, especially functional bacteria. Several recommendations for future research were also proposed according to the actual situation in China.更多还原
