摘　　要：以武汉市桃花岛塘和复合潜流人工湿地组合生态处理系统为研究对象，考察了对城市地表径流的处理效果。结果表明，塘和复合潜流人工湿地组合生态系统可以有效净化城市地表径流，对各污染物的去除率：COD为84．0％～85．4％、TP为89．6％～91．8％、TN为92．2％～94．4％、SS为95．8％-97．1％，其中复合潜流人工湿地对COD、TP、TN、SS的去除率分别为69、0％～73．1％、82．6％～86．6％、89．0％～90．4％、64．7％～69．2％，除氮效果独特。在无雨期该生态系统可用于净化湖水，实现了削减污染和保持系统稳定的双重功能，同时还可补给养鱼塘用水。The ecological treatment system combined by ponds and hybrid constructed wetlands was studied in Taohuadao area of Wuhan City. This system was used to control urban surface runoff and the initial operation of constructed wetlands was discussed. The results show that the ecological treatment system can treat urban surface runoff efficiently. The removal rate of different pollutants in the system is COD 84.0% -85.4%, TP 89.6% -91.8% , TN 92.2% -94.4%, SS 95.8% -97.1% and the removal effieieneies of COD, TP, TN, SS in the hybrid constructed wetlands are 69.0% - 73. 1% , 82.6% - 86.6% , 89.0% - 90.4% , 64.7% - 69.2% respectively. This wetlands system has special function on total nitrogen removal. In the shine season, the lake water can be treated by the hybrid constructed wetlands to achieve the purposes of reducing pollutants and stabilizing the ecological system. Also the effluent of wetlands can provide better treated water for fishing ponds.
