表面流人工湿地处理生活污水研究——以浙江省舟山城北水库人工湿地为例

Study on Domestic Wastewater Treatment in the Subsurface Constructed Wetland

对浙江省舟山市城北水库自由表面流人工湿地运行的污水净化效果和处理系统存在的问题进行了分析和研究。结果表明,湿地在2010年5～10月运行的6个月中,对污水中COD、BOD5、TN、NH4-N和NO3-N的去除率分别为64.40%、44.83%、72.83%、60.98%和35.06%。此外,对工程运行状况的观测发现,人工湿地存在入水量不足及植物管理不善等问题。

The cleaning efficiency of wastewater of the operated subsurface constructed wetland in the Chengbei reservoir in Zhoushan city of Zhejiang Province and the problems in the treatment system were discussed and analyzed in this paper.Results suggested that from May to October in 2010,the main pollutants COD、BOD5、TN、NH4-N and NO3-N were removed at a rate of 64.40%、44.83%、72.83%、60.98% and 35.06% respectively.Furthermore,the investigation of the operation of the project also revealed some problems in the wetland system such as insufficient of influent water in the wetland and poor plant management etc.
