五家堆人工湿地处理污水的工程总结

Summary of Sewage Treatment Project in Wujiadui Constructed Wetland

在大观河河道截污及水环境治理中,通过对五家堆的废弃池塘改造,建设了五家堆人工湿地系统。对该湿地系统处理污水进行了工程总结和分析。结果表明,该系统运行稳定,在公园水体中培养了完整的微生物食物链,既弥补了湿地依靠水生植物治理水体作用缓慢的不足,又解决了工程治理污染水的动物食物链不尽完善的缺陷,使出水水质基本达到《地表水环境质量标准》(GB 3838—2002)的V类标准,成为滇池沿岸湿地整治水环境的典范。

In Daguan River sewage interception and water environment improvement, the Wujiadui constructed wetland system was built by reconstructing abandoned ponds. The sewage treatment project in this system was summarized and analyzed. The results indicate that the system is stable in operation. The complete microbial food chain is cultivated in the park water body, which compensates the slow water im- provement using aquatic plants in the wetland and resolves the defect of imperfect animal food chain in sewage treatment. The effluent quality meets the fifth level criteria specified in Environmental Quality Standards for Surface Water （GB 3838 -2002）. The project provides a successful example on improving and protecting water environment along the Dianchi Lake.
