| 摘 要： | 通过对比不同土壤介质对地下渗滤系统去除污染物的影响,结果表明,粘土易造成土壤堵塞,不适于地下渗滤系统,可通过掺砂和有机物加以调整;砂土具有较高的通气透水性,对有机物、氨氮去除有利但对总氮和总磷去除不利,可通过分层布置(如上砂下壤)加以调整;壤土去除污染物性能最佳,最适宜于地下渗滤系统。

| Abstract: | Effects of different soil matrix on renovation efficiency of subsurface soil infiltration system were studied.The results showed that the clay should unfit for using in subsurface soil infiltration system by reason of soil jam unless it was wixed into sands and organic matters,that that sandy soil shall go against removing total nitrogen and total phosphorus by reason of ventilation unless it was deal with different depths of the matrix,the loam was apt to be used in subsurface soil infiltration system. |
