摘要
为减少入河污染、改善水质,本文对幸福河水环境治理进行了系统研究。针对存在的生活污水入河、合流制管网溢流、内源污染释放及农田退水等问题,在实施控源截污、内源治理、生态沟渠构建及水生态修复的基础上,利用旁路净化工程净化水体中的污染物,保障幸福河主要水质指标(COD_(Cr)、NH_(3)-N、TP)达到地表水Ⅳ类标准,幸福河的治理有助于提高其下游国控断面的水质达标率。
In order to reduce the pollution into river and improve the water quality,this paper systematically studied the water environment treatment of Xingfu River. Aiming at the existing problems of domestic sewage into rivers,overflow of combined drainage network,release of endogenous pollution and farmland drainage,and on the basis of source control and sewage interception,endogenous treatment,ecological ditch engineering and water ecological restoration,the main water quality indexes(COD_(cr),NH_(3)-N,TP)of Xingfu River can reach the class Ⅳ standard of surface water by using bypass purification project which purifies pollutants from water. The treatment of Xingfu River is helpful to improve the water quality compliance rate of the downstram state-controlled section.
