Abstract

To guarantee the river water quality reaching the surface water quality standards，this paper used a small-scale experimental equipment and optimized hydraulic retention time（HRT）and optimum temperature range of the artificial wetland sewage treatment plant effluent, and the effect of advanced treatment was studied.When the HRT of horizontal subsurface flow artificial wetland is 24h and the HRT of vertical flow artificial wetland is 16h, in summer, the COD, Nitrogen and TP removal rate of combined artificial wetland removal rates were 85.0%, 75.0% and 80% respectively. COD of effluent increased when the temperature was less than 5 ℃ in autumn and winter，whatever horizontal subsurface flow artificial wetland, vertical flow artificial wetland or combined artificial wetland was used. Using three wetland, ammonia and TP can removed to some extent. The removal rates of ammonia were 38.2%, 49.8% and 69.01%, respectively. TP removal rates were 61.0%, 66.0% and 87.0%, respectively.
