摘　　要：为削减城市初期雨水的污染负荷,设计了以碎石和碎木片为填料主体的人工强化生态缓冲装置,研究了该系统在较短淹水时间(15、30、60 min)内对城市初期雨水水质的改善效果,分析了生态缓冲带对COD、NH3-N、TN、TP等4种污染物的去除过程和机理。结果表明,15 min淹水时间下对COD、NH3-N、TN、TP的平均去除率分别为37.32%、53.36%、19.04%、31.26%;60 min淹水时间的平均去除率分别为63.72%、71.64%、32.83%、49.35%,平均出水浓度为74.00、3.46、12.13、1.46 mg/L,均达到了城镇污水处理厂污染物排放标准(GB18918-2002)的一级或二级标准。An artificially intensified ecological buffer was designed for the reduction of pollution load of initial rainwater.Gravel and chips was the main body of carrier for buffer. The improved effects for the initial rainwater of the system in a short submerge time（15,30,60 min） were considered. The removal mechanism and process of COD,NH3-N,TN and TP were emphatically analyzed in the test. The results showed that at the submerge time of 15 min,the average removal rates of COD、NH3-N,TN and TP were 37.32%,53.36%,19.04% and 31.26%; At the time of 60 min,the average removal rates were63.72%,71.64%,32.83%,49.35%, the average concentrations in effluent were 74.00,3.46,12.13,1.46 mg / L. The concentrations of pollutions were meet the first or second grade discharge standard of pollutants for municipal wastewater treatment plant（GB18918-2002）.
