摘要
以温州文成西里村生态沟渠为例,调查分析生态沟渠的表流湿地、生态透水坝、反硝化除磷模块、生态塘等措施对沟渠水质的净化效果。结果表明,沟渠末端出口CODCr、氨氮、总磷等主要水质指标稳定达到了《地表水环境质量标准》(GB3838-2002)Ⅲ类水水平,CODCr、氨氮、总磷的浓度分别降低了27.3%、88.5%和50.0%。说明该生态沟渠对氮、磷有着良好的拦截效果,可为浙南山区氮、磷拦截生态沟渠建设提供有益的借鉴。
This paper takes the ecological ditches of Wencheng Xili Village in Wenzhou as an example to investigate and analyze the purification effects of the surface wetlands,ecological permeable dams,denitrification and phospho⁃rus removal modules,and ecological ponds on the water quality of the ditches.The results show that the main water quality indicators such as CODCr,ammonia nitrogen and total phosphorus at the end of the ditches have stably reached the level of“Surface Water Environmental Quality Standards”(GB3838-2002),and the concentrations of CODCr,am⁃monia nitrogen and total phosphorus have been reduced by 27.3%,88.5% and 50.0%respectively.indicating that the ecological ditches has a good interception effect on nitrogen and phosphorus,and has good reference value for the con⁃struction of nitrogen and phosphorus interception ecological ditches in the mountainous area of southern Zhejiang.
