摘要
以分宜县龙须沟水环境提升项目为例对水质数据进行统计分析,研究表面流人工湿地群提升水源地入库河流水质的适用性及效果。在完成控源截污和内源治理后,龙须沟流域仍存在一定面源污染和雨季溢流污染问题,表面流人工湿地群可提高生态净化能力,适用于提升沿线分布有池塘及沼泽地的微污染河流水质。龙须沟沿线建设了5座表面流人工湿地组成的人工湿地群,总占地面积为458 813 m^(2),统计分析2021年水质监测数据,入湖口水质稳定达到了地表Ⅲ类水质标准。
Taking Longxugou water environment improvement project in Fenyi county as an example,the water quality data after completion of the project were analyzed to study the applicability and effect of surface flow constructed wetland group on improving water quality of the river entering reservoir in water source region.After the completion of pollution source control and endogenous treatment,there are still some non-point source pollution and rainy season overflow pollution problems in Longxugou watershed.Surface flow constructed wetland groups can improve the ecological purification capacity,and are suitable for improving the water quality of slightly polluted rivers with ponds and swamps along the river line.An artificial wetland group consisting of five surface flow artificial wetlands has been built along the Longxugou River,covering a total area of 458813 m^(2).According to the statistical analysis of the water quality monitoring data in 2021,the water quality at the entrance of the lake has reached the Class II surface water quality standard.
