摘　　要：福州市浦东河水系是典型的城区黑臭水体,一直以来面临着外源污染严重、内源污染累积、生态基流匮乏、生态系统退化等问题。根据水系流域特征,统筹考虑水环境、水生态、水景观,采用以“控源截污、内源治理、活水提质、生态修复”为主的技术路线对浦东河水系进行了综合治理,经评估,沿线排口溢流水量、COD和NH_(3)-N入河污染负荷分别削减了49.9%、77.0%和92.2%。根据工程实际运营情况,浦东河水系COD浓度长期稳定在30 mg/L以内,NH_(3)-N浓度稳定在4 mg/L以内,治理效果良好。阐述了治理措施中关键要点的设计经验及注意事项,为类似城区黑臭水体治理工程实施提供借鉴参考。Pudong river system is a typical urban black-odorous water body in Fuzhou,which has been facing with problems such as serious external pollution,accumulation of internal pollution,lack of instream flow,and ecosystem degradation.According to the characteristics of the drainage basin and overall consideration of"water environment,water ecology and water landscape",the technical route of"external pollution control,internal source treatment,improvement of water flow and quality,and ecological restoration"was adopted to solve the problem of Pudong river system.It was estimated that the overflow rate,COD and ammonia nitrogen pollution loads were reduced by 49.9%,77.0%and 92.2%,respectively.According to the operation data,COD concentration in the Pudong river system was stable under 30 mg/L,and the ammonia nitrogen was stable under 4 mg/L,which showed good treatment results.This paper expounded the design experience and key points in the treatment measures and provided references for the similar urban black-odorous water treatment projects.
