| 摘 要： | 为降低中小型污水处理厂剩余污泥好氧消化的动力消耗，对城市污水处理厂剩余污泥在低溶解氧状况下的消化进行了初步研究，并进行了连续流的中试实验。通过监测污泥体积的消减和挥发性有机物降解的实验结果表明，在低污泥浓度下，曝气量为好氧消化的1／2时，污泥中有机物降解率在50％以上，达到了较好的稳定化效果。污泥微氧消化工艺为中小型污水处理厂的污泥稳定化处理提供了新思路。

| Abstract: | Based on pilot dynamic experiments on traditional activated sludge wastewater treatment plant,we do some research on sludge digestion in lowdissolved oxygen concentration for reducing the energy consumption of aeration sludge digestion.The results of this experiment show,when the air amount depressed to1/2of traditional aeration sludge digestion needed,the Volatile Suspend Solid(VSS)degradation rate of the sludge could be reduced about50?ter20days digestion.It is a new method for minitype wastewater treatment plant to treat the excess sludge. |
