| 摘 要： | 通过向处理系统中投加填料对污泥减量的效果进行了研究.试验结果表明:投加填料后处理系统的污泥浓度平均值为3 509 mg/L,出水CODCr平均值为42 mg/L,CODCr平均去除率为88%;未投加填料处理系统的污泥浓度平均值为4 815 mg/L,出水CODCr平均值为77 mg/L,CODCr平均去除率为77%.投加填料处理系统的污泥浓度、出水CODCr值均低于未投加填料的处理系统,因此是一种可行的剩余污泥减量方法.

| Abstract: | The paper studied the effect of adding carrier into bi oreactor on reduction of residual sludge.The results indicated that in the adding carrier system, the average concentration of mixed liquid suspended sludge(MLSS) was 3509mg/L, the average value of effluent COD_(Cr) was 42mg/L,the average clearance rate of COD_(Cr) was 88%,In no carrier system,however,the average concentration of MLSS was 4 815mg/L,the average value of effluent COD_(Cr) was 77mg/L,the average clearance rate of COD_(Cr) was 77%.By comparing the results,we condude that adding carrier in bioreactor is a feasible method to reduce residual sludge. |
