SUFR系统活性污泥特性及稳定性研究
Study on characteristics and stability of activated sludge in SUFR system
摘要
Abstract
Characteristics of activated sludge,influence of influent COD concentration,SRT and the interrupting operations on stability in SUFR system were studied.The results shows that the sludge particle diameter in SUFR system belongs to small particle sludge ranging from 0.7 to 0.9 mm,and the settling characteristics of the sludge,as well as the removal effects to nitrogen and phosphorus are good.The removal effect of N in SUFR system to SRT has some resistance to shock loading,but it is largely influenced by influent COD.The removal effect of P has good resistance ability to the change of SRT and influent COD.After the break of the operation for 72 hours in SUFR,the settling performance of the sludge and removal effects of N and P decreased obviously,but the system can return to normal in almost one week.关键词
