Abstract :
Rural sewage has been treated by using the use of artificial soil rapid infiltration system, after 12 days the CRI complete to start. The impact of soil column height and soil-sand ratio was studied to removal ratio of sewage, the results showed that the best soil column height was 500mm, total nitrogen removal rate can reached 64%. When the soil-sand ratio was 1:1, removal rate of COD and TN were best , and effluent quality achieved "urban sewage treatment plant emission standards" (GB18918-2002) in a B standard.
