摘　　要：基于倒水河冯集断面修复工程项目,探讨了生态沟渠、二级塘与人工湿地组合工艺在污水处理厂尾水和初期雨水深度处理中的应用效果。研究结果表明,该组合工艺对COD_(Cr)、NH_(4)^(+)-N、TP和TN的平均去除率分别为68.88%、85.37%、79.29%和47.73%,出水水质满足GB 3838—2002《地表水环境质量标准》中的Ⅳ类标准,且运行稳定可靠。经济分析显示,该工艺的单位投资为600元/m^(3),直接运行成本为0.19元/m^(3),表明其在较低的投资和成本下能够有效提高尾水水质。该项目的实施为类似工程提供了宝贵的技术经验和参考。Based on the restoration engineering project of Fengji section of Daoshui River,the application effect of the combined process of ecological ditches,secondary ponds,and artificial wetlands in the deep treatment of tail water from sewage treatment plant and initial rainwater were discussed.The research results showed that,the average removal rates of COD_(Cr),NH_(4)^(+)-N,TP,and TN by this combined process were 68.88%,85.37%,79.29%,and 47.73%respectively.The effluent water quality met the Class IV standard of GB 3838—2002 Environmental Quality Standards for Surface Water,and the operation was stable and reliable.The economic analysis showed that the investment of this process was 600 yuan/m^(3),and the direct operating cost was 0.19 yuan/m^(3),indicating that it can effectively improve the quality of tail water at a lower investment and cost.The implementation of this project has provided valuable technical experience and reference for similar projects.
