断头河浜水环境原位修复工程示范

The Project of In-Situ Remediation of Truncated Creek Water Environment

在对江苏省常州市谈家头村现状调研勘察的基础上,充分利用现场地形,以断头河浜为依托,构建人工浮岛和曝气鱼塘,采用地埋式微动力A/O法+曝气鱼塘组合工艺模式治理修复农村生活污水与河浜生态环境污染。改善了浜内鱼塘放养环境,实现该村生活污水治理、生态环境修复、水产养殖增收三位于一体。工程运行结果表明,出水水质指标COD、TP、NH3-N、TN均低于GB 18918-2002一级B排放要求,河浜内水体恢复至GB3838-2002Ⅲ类水质。该工程对于太湖流域周边农村地区生活污水的治理具有良好的示范及推动作用。

To treat the rural sewage and environmental pollution of creek by using the combined process of "Buried the decline of the power of A/O + aerated fish pond",the artificial floating island and aerated fish pond relied on the creek were built based on the full survey of the terrain of Tan-jia-tou village and the site topographic conditions.The project improved the environment of fish farming,and achieved the trinity of village sewage treatment,environmental remediation and the increasing income of aquaculture.Results showed the effluent concentration of COD 、TP、NH3-N、TN could meet 1-B Discharge Standard of GB 18918-2002,and the creek water could reach grade Ⅲ Quality Standard of GB 3838-2002.The project has good demonstration and impact on the management of rural sewage along Taihu lake.
