Title: Research progress on small district's domestic sewage treatment models
Abstract: This paper analyzed the present situations about small district's domestic sewage treatment models,and discussed the advantages and disadvantages of centralized and decentralized treatment models.Based on the analysis of the technical characters of various land treatment systems,it was pointed out that constructed wetland and subsurface infiltration system had prominent ecological and cleaning functions in the treatment of domestic wastewater,which could be used to construct an ecological land treatment model,and applied to treat small district's domestic sewage.After considering the characters and application limitations of land treatment system,it was suggested that strengthened pretreatment should be emphasized,and the operation way with low influent pollutant concentration and high hydraulic load should be adopted.
