摘　　要：城市黑臭河流不仅破坏景观、散发着令人难闻的气味,更会破坏河流原本的生态系统。以深圳龟岭河为例进行研究,采用截污控源、内循环改造、曝气增氧和生物膜系统构建的组合工艺治理该黑臭河流。结果表明:治理后水体的透明度、溶解氧(DO)、氨氮(NH_(3)-N)和总磷(TP)满足GB 3838—2002《地表水环境质量标准》Ⅴ类水体标准,氧化还原电位(ORP)大幅度提高,黑臭现象得到消除。该工艺对黑臭水体水质提升实际有效,具有较高的技术实施特性,为黑臭河流治理提供了借鉴和参考。Urban black odorous rivers not only emit unpleasant odor and destroy the landscape,but also destroy the original ecosystem of the river.In this project,a combination of interception and source control,internal circulation modification,aeration and oxygenation and biofilm system construction was used to treat the black odorous river in Shenzhen Guiling River as an example.The results show that the transparency,dissolved oxygen(DO),ammonia nitrogen(NH_(3)-N)and total phosphorus(TP)of the treated water body meet class V of the Surface Water Environmental Quality Standard(GB 3838-2002).The oxidation reduction potential(ORP)is improved greatly and the black odor phenomenon is eliminated.The process is practically effective in improving the water quality of black smelly water bodies and has high technical implementation characteristics,which provides reference for the treatment of black smelly rivers.
