摘　　要：为了使成都市新都区苟家滩引水枢纽上游两座污水处理厂达到《四川省岷江、沱江流域水污染物排放标准》(DB51/2311-2016)的尾水得到进一步深度处理,并使其达到《地表水环境质量标准》(GB 3838-2002)中的Ⅲ类水指标限值,构建了一种复合型人工湿地污水处理系统。该人工湿地设计处理规模为7×10^(4) m^(3)/d,采用了多级串联的复合型人工湿地。该工程的实施,进一步保障了毗河供水工程水质,是污水处理厂厂外提标的典型案例,具有较好的示范作用。In order to make of the two wastewater treatment plants upstream of Goujiatan Water Diversion hub in Xindu District of Chengdu meet the“Sichuan Minjiang river and Tuojiang River Basin Water Pollutant Discharge Standard”(DB51/2311-2016)tail water get to be further treated,and make it reach the limit of classⅲwater index in“Environmental Quality Standard for Surface Water”(GB 3838-2002),construct a kind complex constructed wetland sewage treatment system.The designed treatment scale of the constructed wetland was 7×10^(4) m^(3)/d,and the multi-stag e series complex constructed wetland was adopted.The implementation of this project has further guaranteed the water quality of Pihe water supply project,which is a typical case of raising the standard outside the sewage treatment plant and has a good demonstration effect.
