摘　　要：厌氧颗粒污泥的流失是高效厌氧反应器实际运行中经常发生的现象,污泥流失严重时会导致反应器性能大大地降低。从颗粒污泥的沉降性能与反应器的操作条件等角度深入探讨了颗粒污泥流失的原因,指出提高颗粒污泥的沉降性能是防止污泥流失的根本途径,控制厌氧反应器的有机负荷是控制污泥过量流失的主要方法。Anaerobic granular sludge wash-out is a phenomenon that commonly happens in the practical operation of high efficiency anaerobic reactor,and the treatment capability of the reactor would be greatly decreased if the condition is serious.The reasons that caused the granular sludge wash-out was deeply discussed from the aspects of sedimentation performance of the granular sludge,operation condition of the reactor and so on.It was pointed out that,both promoting the sedimentation performance of the sludge and controlling the organic loading of the anaerobic reactor were the main effective measures to prevent excessive sludge wash-out.
