| 摘 要： | 研究了投加酵母菌群、光合细菌群和混合菌群等多功能微生物菌群促进炼厂的剩余污泥的减量化效果。通过多次污泥减量试验,观察到在好氧消化基础上投加功能菌群能显著促进炼厂剩余污泥减量化。结果表明,与仅好氧曝气条件下相比,投加酵母菌群、光合细菌群、混合菌群的MLSS去除率明显提高了13.81%、30.58%、37.94%;投加功能菌群作用后的污泥沉降性能均优于投加前;pH值均逐渐降低。功能微生物降解效应使石油组分发生明显的变化,强化了对低中碳正构烷烃的降解程度,有利于将高碳链烃降解为低碳链烃。

| Abstract: | The refinery residual sludge reduction using multi-function microbe,which consists of mixed yeast strains,photosynthetic bacteria and mixed bacteria was studied. After a period of research time,the excess sludge reduction experiment shows that function microbe was improved the reduced effect of excess sludge significantly.The results show that compared with blank test,MLSS removed rate of the sludge are increased by 13.81% for mixed yeast strains,by 30.58% for mixed photosynthetic strains and by 37.94% for ... |
