摘　　要：深圳市燕栖湖水系是典型的城市内湖,为了提升周边居民的幸福感,对其进行水环境综合整治。微污染状态下的燕栖湖水系主要存在有机污染物超标、水体感官效果差、水动力不足及水生态不完善的问题。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,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》(CB/T3838-2002)中Ⅳ类水标准,BOD5和氨氮分别稳定在6mg/L和0.32mg/L以内。Yanqi Lake water system in Shenzhen was a typical urban inner lake,and it had carried out a series of projects to improve the water quality in order to promote the well-being of the surrounding residents.It was found that Yanqi Lake water system,as a slightly polluted urban inner lake,had the mainly problems of excessive organic pollutants,poor sensory effect of water body,insufficient hydrodynamic force and imperfect aquatic ecosystem.After sewage had been intercepted,coupled with series of projects that sediment had been cleaned,pollutants had been blocked,water cycle had been hanced,aquatic ecosystem had been reconstructed,the water quality was improved to the Category Ⅳ standard in"Environmental quality standard for surface water(CB 3838-2002)"as well as BOD,and ammonia nitrogen in the lake were stable below 6mg/L and O.32mg/L respectively.
