| 摘 要： | 为研究不同溶解氧（DO）下细胞自溶过程对城市生活污水处理厂生化污泥减量效果的影响,实验通过控制污泥DO值分别为4.0、4.5、5.0、5.5、6.0 mg/L进行污泥好氧消化实验,并以MLSS、TN、TP的变化情况来表征污泥减量效果,结果表明：当DO值为6 mg/L和5.5 mg/L时,曝气作用时间大于5 d时,污泥减少量分别达59.0%和53.0%,减量效果十分显著。同时对污泥上清液TN、TP的考察表明,在污泥减量的同时应注意解决尾水的处理问题。

| Abstract: | In order to investigate slugde reduction under different dissolved oxygen（DO） in aerobic digestion process,the variation of MLSS、TN、TP were measured under the conditions of DO values were 4.0、4.5、5.0、5.5、6.0 mg/L.The results showed that when DO values were 6.0 mg/L and 5.5 mg/L,under aeration for more than 5 days,reduction of sludge could reach to 59.0% and 53.0% respectively.In addition,by determining the concentrations of TN and TP,it was concluded that supernatant effluent should be concerned when sludge was treated. |
