摘要
为改善水环境质量,实现河道"污水零直排",对十甲河、北塘河和永久河等15条河道沿线的排放口进行了排查。对于有污水的排放口实行源头截污并入市政污水管网,对于不具备市政截污条件的,就地建设污水处理设施,污水经处理后排入河道。工程运行效果表明,污水就地处理设施的出水水质达到了《城镇污水处理厂污染物排放标准》(GB18918-2002)的一级B标准,消除了河道晴天排污现象。
In order to improve the quality of water environment and achieve the goal of sewage zero-discharging for rivers, the outlets of the fifteen rivers such as the Shijia River, Beitang River and Yongjiu River were investigated. The sewage outlets were intercepted from the source into the municipal sewage pipe network, while the situ treatment facilities were built without the municipal sewage interception conditions and the effluent was discharged into the rivers after the treatment on the spot. The engineering operation effect shows that the effluent quality of the situ treatment facilities has reached the first level B standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB18918-2002） and eliminated the discharge phenomenon in fine days.
