摘　　要：将“预处理沉淀+垂直潜流人工湿地+表面流人工湿地+氧化塘”生态湿地组合处理技术应用于四川省长江水系的一段微污染支流的水质净化处理。利用现有地形及高程差,由低处河道取水泵入沉淀池,依次经过各生态湿地水处理单元处理后再排入河道,结果表明:整个处理系统对污染物的净化处理效果良好,氨氮、总氮、总磷和COD_(Mn)经处理后大幅度消减,出水水质可达地表水Ⅴ类-Ⅱ类标准,其中垂直潜流人工湿地单元处理效果最好,并对实际运行中存在的问题进行分析,提出针对性改进措施。The combined treatment technology of“pre-treatment sedimentation+vertical subsurface flow artificial wetland+surface flow artificial wetland+oxidation pond”ecological wetland is applied to the water quality purification treatment of a slightly polluted tributary of the Yangtze River system in Sichuan Province.Utilizing the existing terrain and elevation differences,water is pumped from the lower reaches of the river into a sedimentation tank,which is sequentially treated by various ecological wetland water treatment units before being discharged into the river.The results show that the entire treatment system has a good purification treatment effect on pollutants,with ammonia nitrogen,total nitrogen,total phosphorus,and COD_(Mn)significantly reduced after treatment.The effluent quality can reach the surface water Class V-II standard,among which the vertical subsurface flow artificial wetland unit has the best treatment effect.The study analyzes the problems that exist in actual operation and propose targeted improvement measures.
