| 摘 要： | 以霍夫水丝蚓（L.hoffmeisteri）为研究对象,考察了生长方式、溶解氧（DO）、酸碱度（pH）和温度（T）对其污泥减量效果的影响.结果表明,附着生长时污泥减量效果优于悬浮生长,附着生长时的TSS、VSS降解率分别为22.34%、29.79%,而游离生长时的TSS、VSS降解率分别仅为15.51%、18.12%;...

| Abstract: | The effects of environmental factors such as growth type,pH,DO and temperature on sludge reduction by L.hoffmeisteri were investigated in this study.Experimental results indicated that sludge reduction in the attached growth system was better than that in the suspended growth system.The reduction efficiencies of TSS and VSS were 22.34% and 29.79% in the attached growth system,respectively.In contrast,only 15.51% and 18.12% reduction of TSS and VSS were observed in the suspended growth system.The sludge redu... |
