[ Method] By studying on the removal of conventional pollutants such as CODcr, SP, TP and NH4^＋-N with new wetlands, their impact on the capacity of sewage treatment. [Resuit]The CODcr removal efficiency could reach 70% -80% and the value of CODcr could be reduced from above 300.00 mg/L to blow 100 mg/L, the removal efficiency of SP and NH4^＋-N was 30% -40% when hydraulic load is 90 crn/d. [ Conclusion] When the concentration of CODcr, SP and NH4^＋ -N were below 300.00,2.50 and 15.00 mg/L, it＇s easy to achieve a more stable removal efficiency.展开更多
