厌氧污泥接种好氧反应器处理生活污水的启动研究

摘要：

以模拟乡镇生活污水为处理对象,利用厌氧污泥接种启动好氧小试反应器,采取连续进水连续曝气的方式,进行构建好氧生物处理系统,考察驯化过程反应器中污染物的去除效率.实验结果表明:常温条件下,模拟生活污水进水量为4 L/d,HRT(水力停留时间)为12 h,进水均值COD(化学需氧量)为400 mg/L,NH4^+-N(氨氮)为20 mg/L,TN(总氮)为25 mg/L,TP(总磷)为4 mg/L,运行12 d,实验出水COD为39.80 mg/L,NH4^+-N为0.98 mg/L,TN为8.32 mg/L,TP为0.96 mg/L;运行29 d,COD、NH4^+-N平均去除效率均可稳定达到90.0%,活性污泥生长良好,初步构建好氧生物处理系统.

Taking township domestic sewage as samples,the small device which cultivated by anaerobic sludge was used to construct the environment of aerobic biological with the method of continuous into water and continuous aeration,and the efficiency of pollutants removal was being observed.The results indicated that under the condition of normal temperature,sewage inflow 4 L/d,HRT 12 h,average COD 400 mg/L,NH4^+-N 20 mg/L,TN 25 mg/L,TP 4 mg/L;after 12 days,sewage outflow COD 39.80 mg/L,NH4^+-N 0.98 mg/L,TN 8.32 mg/L,TP 0.96 mg/L;after 29 days,COD and NH4^+-N removal efficiency can both reach 90.0%,and aerobic activated sludge grew well.It showed the aerobic biological treatment system was successfully constructed.
