摘　　要：为提高人工湿地系统污水处理效率,设计一种序批式自动增氧型人工湿地,采用间歇运行方式,探讨其在运行条件下,停留时间及排空闲休时间对去污效能的影响。结果表明,序批式自动增氧型人工湿地较理想的运行工况,为间歇瞬时进水-反应沉淀42h-瞬时出水-待机闲休12h;在此工况下,当进水SS、COD、TN和TP平均浓度分别为51、68、13.4和1.0mg/L时,相应的去除率分别为81.2%、85%、89.9%和77.9%。In order to improve the efficiency of wastewater treatment, a sequencing batch self - aeration constructed wetland was designed, starting with intermittent operation. The effects of hydraulic retention time （HRT） and idling time on pollutant removal were investigated. The experimental results showed that the ideal operating conditions of the sequencing batch wetland were instanta- neous - influent 24 h reaction - instantaneous drainage, then idle 12 h. Under these circumstance, when the influent SS = 51 mg/L, COD =68 mg/L, TN = 13.4 mg/L and TP = 1.0 mg/L, the removal rate of SS, COD, TN, TP could reach 81.2% ,85% ,89.9% and 77.9% , respectively.
