摘　　要：深圳市燕栖湖水系是典型的城市内湖,在微污染状态下,燕栖湖水系主要存在有机污染物超标、水体感官效果差、水动力不足和水生态不完善的问题。为了提升周边居民的幸福感,通过控源截污、底泥清淤、水面拦渣、强化循环、生态重建的系统工程措施,对其进行了水环境综合整治。整治后,湖泊水环境质量由微污染状态稳定提升至《地表水环境质量标准》(GB 3838—2002)中Ⅳ类水标准,BOD5和氨氮质量浓度分别稳定在6 mg/L和0.32 mg/L以内。The water system of Yanqi Lake in Shenzhen is a typical urban internal lake.In slightly polluted state,there are the problems of excessive organic pollutants,poor sensory effect of water body,insufficient hydrodynamic force and imperfect water ecology in the water system of Yanqi Lake.In order to promote the well-being of the surrounding residents,the systematical engineering measures of controlling source,intercepting sewage,dredging sediment,containing water surface dregs,strengthening circulation and rebuilding ecology are taken to comprehensively improve the water environment of the lake.After improved,the quality of lake water environment has been steadily improved from the micro-pollution state to the Class IV water standard in the Surface Water Environmental Quality Standard(GB 3838—2002).And the mass concentration of BOD5 and ammonia nitrogen is stable within 6 mg/L and 0.32 mg/L,respectively.
