摘要
采用ABR+复合人工湿地组合工艺对农村分散型生活污水进行中试研究。试验期间进水pH和温度的范围分别为:6.5～8.5,14.0～23.5℃。结果表明:ABR在HRT为10 h,COD容积负荷为0.52 kg/(m3.d)(复合人工湿地面积负荷为0.018 kg/(m2.d))的条件下,系统对COD、NH3-N、TN、TP和浊度的平均去除率分别为:78%、64%、60%、63%和80%;出水平均质量浓度分别为:47,7.13,13.31,0.67 mg/L,浊度为10 NTU;系统运行24 d后,ABR反应器中观察到厌氧颗粒污泥。
The combined system of anaerobic baffled reactor＋combined constructed wetland with low power was applied to treat the dispersed rural domestic sewage.During the start-up of this system,the range of pH and temperature in ABR reactor was 6.5～8.5 and 14.0～23.5 ℃ respectively with the HRT was 10 h,and the COD volume load was 0.52 kg/（m3·d）.The results show that the average of removal rates of COD,NH4＋-N,TN,TP and turbidity was 78%,64%,60%,63% and 80%,and correspondingly the average of effluent concentration was 47,7.13,13.31,0.67 mg/L and 10 NTU.After 24 d,the anaerobic granular sludge was observed in the ABR reactor.
