摘要
对由不同渗透速率的土壤组成的复合床快速渗滤系统进行了研究．在渗透系数大的土壤上覆盖一定厚度的渗透速率适宜的滤层可以组成复合床快渗系统，该系统具有出水水质好、运转稳定、施工简单、维护方便等特点，适宜于在砂壤土质的地区建造快渗场．
The soil of larger infiltration coefficient is covered with the filtration layer of suitable infiltration rate to form composite--bed rapid infiltration system, which has characteristics of good effluent.smooth operation.simple construction and easy maintenance ; therefore it' s properly applied in thearea of sandy loam.
