摘　　要：对低温条件下SBR活性污泥沉降性能的影响因素问题进行了试验研究.研究表明,进水中的SS对活性污泥沉降性能有改善作用,而腐化的污水对活性污泥沉降性能有不利的影响;当SBR系统在中有机负荷(Ns=0.18 kgCOD/(kgMLSS.d)情况下运行时,活性污泥沉降性能良好;低DO质量浓度(DO≤1.0mg/L)会导致SBR系统的活性污泥沉降性能恶化.A concentrated study of the factors of sedimentation performance of SBR activated sludge under low temperature was involved in this paper. The factors that the putrid waste water have bad effect on sedimentation performance of SBR activated sludge shown that the inflow SS distinctly improve sedimentation performance of activated sludge. However, the pythogenous sewage evidently worsen sedimentation performance of activated sludge. When loading rate is 0.18 kg COD/（ kgMLSS · d）, the sedimentation performance of SBR activated sludge do well. The less DO concentration results in sludge bulking in SBR system.
