摘　　要：针对雨季混流污水入湖造成马鞍山市东湖污染严重的问题,采用"末端截污+初雨收集+源头混接改造"截留旱季污水和初期雨水,同时结合水质净化与水生态修复组合工艺,对东湖水环境进行治理。文中解析了入湖污染负荷,介绍了工艺流程、水质净化设计和水生态修复设计。监测结果表明:在截污措施、水质净化与水生态修复的协同作用下,治理后主要水质指标在雨后15 d达到《地表水环境治理标准》(GB 3838-2002)V类标准。In view of serious pollution of East Lake in Ma'anshan City caused by mixed flow of sewage in the rainy season,the process of“intercepting sewage+intercepting initial rain+diversion of rain and sewage”are used to intercept sewage and initial rain pollution,and a combination of water purification and water ecological restoration technology is used to treat water environment of East Lake.The paper analyzes pollution load into the lake,introduces technological process,water quality purification design and water ecological restoration design.Monitoring results show that the main water quality indicators of the 15 days after the rain reach class V criteria specified in Environmental Quality Standards for Surface Water(GB 3838—2002)under the collaborative effect of pollution interception measures,water purification and water ecological remediation.
