| 摘 要： | 利用昆明当地的土壤在室内填装一个土柱渗滤系统，使用配水浓度模拟昆明市区雨水径流污染物浓度，进行去除雨水径流污染物的实验研究，考察系统对COD、TN、NH4＋、NO3^-、NO2^-和TP的去除效果。实验结果表明，该土壤渗滤系统对COD平均去除率为82．04％，对TN的平均去除率为22．64％，对NH；平均去除率为94．26％，但是对NO3^-、NO2^-去除效果较差，对TP平均去除率为96．95％；另外，系统长期运行导致下渗速度降低，出水效果反而变好。

| Abstract: | Artificial water was made according to actual runoff pollutants in Kunming City. A soil column infiltration system was made using the local soil, to remove the stormwater pollutants in the removal study. The removal efficiencies of COD, TN, NH4+, NO3-, NO2-and TP were investigated by the system. The results showed that the average removal rate of COD was about 82.04%, and TN was about 22.64%, and NH4+ was about 94.26%, but less effective for removing NO3- and NO2-, and TP was about 96.95%. In addition, the long-term operation of the system reduced the infiltration speed. Instead, outflow effects of stormwater were changed better. |
