摘　　要：在城市景观基塘湿地系统的基础上,通过在基塘中种植多种水生植物进行生物强化处理,探讨了多水塘湿地系统对城市地表径流氮、磷、COD等污染物的削减能力,分析了城市地表径流氮、磷、COD等污染物浓度沿程的变化趋势。结果表明:降雨前、降雨后多塘系统对城市地表径流具有较好的处理效果;面积越大、植被盖度越高的塘对地表径流污水的处理效果越好;无论是降雨前还是降雨后,经过人工设计的基塘比自然基塘的污染物去除效率更高。总体而言,城市景观基塘湿地系统对地表径流具有较好的处理效果,降雨后相比降雨前具有更高的去除效率,TN、TP、NH+4-N、COD均表现出沿程削减的趋势。Based on the wetland system of urban landscape dike-pond,and enhanced biological treatment of dike-pond by planting a variety of aquatic plants,this paper discusses the ability of multi-pond wetland system to reduce nitrogen,phosphorus,COD and other pollutants in urban surface runoff,and analyzes the concentration change of nitrogen,phosphorus,COD and other pollutants in urban surface along the lake.The results show that:Before and after rain,the multi-pond system has a better treatment effect on urban surface runoff;the larger the area and the higher the vegetation coverage,the better the treatment effect on surface runoff sewage.Both before and after the rain,artificially designed dike-ponds have higher pollutant removal efficiency than the natural dike-ponds.In overall,the wetland systems of urban landscape dike-pond have better treatment effect on surface runoff,the removal efficiency after rain is higher than that before rain,and TN,TP,NH+4-N,COD reduces along the lake.
