摘要
采用A／A／MBBR工艺处理由粪便液和生活污水组成的混合污水，试验条件：填料投配比为20％，好氧池1和好氧池2中的填料体积比为1：3，好氧池的水力停留时间为5h，混合液回流比为120％，污泥回流比为60％，泥龄为6d，好氧池的溶解氧为3．0mg／L，温度为16～20℃。系统稳定运行一个月的结果表明：脱氮除磷效果及对有机物的去除效果均稳定而良好，出水氨氮、总氮、总磷和COD平均浓度分别为0．3、12．9、0．35和36．22mg／L，均达到了国家一级A排放标准。
The A/A/MBBR process was used to treat the mixed wastewater of domestic sewage and fecal sewage. The condition of experiment is that the ratio of the carriers is 20% , the volume ratio of car- riers between the aerobic tank 1 and the aerobic tank 2 is 1 ： 3, the HRT in the aerobic tanks is 5 h, the mixed-liquid return ratio is 120% , the sludge return ratio is 60% , the sludge retention time is 6 days, the DO in the aerobic tanks is 3.0 mg/L and the temperature is 16 to 20 ℃. After a month of operation, the system has stable and better removal efficiency of nitrogen, phosphorus and organic matter. The aver- age concentrations of NH3 - N, TN, TP and COD in the effluent are O. 3 mg/L, 12.9 rag/L, 0.35 mg/L and 36.22 mg/L respectively, meeting the first level A criteria specified in the national discharge standard.
