摘　　要：[目的]研究厌氧+人工湿地对高负荷污水处理的能力。[方法]通过新式湿地对CODCr、SP、TP和NH4+-N等常规污染物的去除,研究其对污水处理的能力。[结果]采用90cm/d水力负荷运行时,CODCr去除率可达70%～80%,可将300.00mg/L以上的CODCr降低至100.00mg/L以下,对SP和NH4+-N的去除率在30%～40%。[结论]人工湿地的CODCr、SP及NH4+-N浓度为300.00、2.50、15.00mg/L以下时,能达到较稳定去除效率。[ Objective] The research aimed to study on capacity of sewage treatment with anaerobic ＋ artificial wetland. [ Method] By studing on the removal of conventional pollutants such as CODCr, SP, TP and NH4^＋-N with new wetlands to analysis their impact on the capacity of sewage treatment. [ Result] 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 were 30% -40% when hydraulic load is 90 cm/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.
