摘　　要：选择梅雨时节武汉市海绵城市建设试点东湖港某集中排水口区域的初期雨水作为研究对象,探究曝气条件下挂膜碳素纤维对初期雨水的处理机制及效果.结果表明:碳素纤维挂膜效率高,实验控制条件下经过5 d的挂膜后,其生物膜已具有很好的生物活性;并且挂膜碳素纤维对初期雨水具有良好的净化效果,经7 d处理后,初期雨水中氨氮(NH3-N)、总氮(TN)、总磷(TP)、高锰酸盐指数、化学需氧量(COD)的去除率分别达到93.5%、69.6%、62.8%、76.7%、72.1%,处理后各水质指标均达到东湖港水质要求,该研究对海绵城市的建设与发展具有一定的指导意义.The initial rainwater in a central drainage outlet area of Donghu Port,a pilot project of sponge city construction in Wuhan in plum rain season was selected as the research object.The mechanism and effect of carbon fiber with membrane on initial rainwater treatment under aeration condition were studied.The results show that the carbon fiber had high efficiency of film deposition.The biofilm had a good biological activity after 5 days of hanging under the experimental conditions.And the carbon fiber deposited on the membrane has good purification effect on the initial rainwater.After 7 days of treatment,the removal rates of NH3-N,TN,TP,permanganate index and COD in initial rainwater were 93.5%,69.6%,62.8%,76.7%and 72.1%,respectively.After the treatment,have reached the water quality requirements of Donghu Port water quality indexes.It has important guiding significance for the construction and development of sponge city.
