摘　　要：前锋净水厂位于广州市番禺区,已建规模20万m^3/d,其扩建三期工程设计规模为20万m^3/d,属于广州市重点工程。根据服务范围内污水水质变化不确定的特点,扩建三期工程采用"多模式AAO生物反应池+矩形周进周出二沉池+砂滤池+次氯酸钠消毒"组合工艺路线。处理后的尾水达到国家《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A出水标准和广东省地方标准《水污染排放标准》(DB44/26-2001)一级标准的较严值。现详细介绍该工程的工艺流程、进出水水质指标、主要构筑物的设计参数及工艺特点。Qianfeng Water Purification Plant is located in Panyu District of Guangzhou City. Its built scale is200 000 m3/d. Its design scale of Extension Phase III Project is 200 000 m3/d. It is an important project of Guangzhou City. Based on the characteristics of uncertain wastewater quality within the service range, the combined technology of multimode AAO biological reaction tank + rectangle secondary settlement tank +sand filter + sodium hypochlorite disinfection is used in the extension Phase III project. The treated tail water reaches the first grade A effluent standard of the national Pollutant Discharge Standard of Urban Sewage Treatment Plant(GB18918-2002) and the first grade standard of the local standard Water Pollution Discharge Standard(DB44/26-2001) of Guangdong Province. The article introduces the technological flow of this project, the water quality indexes of influent and effluent, and the design parameters and technological characteristics of main structures.
