【Abstract】 Three nonplant wetland systems have been constructed respec- tively with the same bottom slope decrease and total volume by three kinds of soil consisting of different ratio of sand,c(?)ay and broken stones.Under the same volume wastewater load and external conditions,this paper prelimi- naryly discusses the relationship of the type of soil with the antificial wet- land in disposing wastewater,and proveides a better method cf composing sa- nd-soil-broken stones.更多还原
