摘　　要：在低温条件下,观察了膨胀活性污泥,通过调整厌氧-好氧反应器的运行工况,解决了其低温膨胀问题,并探讨了常温条件下系统恢复的途径和长期稳定运行的工况。结果表明,低温膨胀污泥同时具有非丝状菌性和丝状菌性污泥膨胀的特点;系统常温恢复时间比低温恢复时间可以缩短5d,好氧污泥较厌氧污泥更易于系统的恢复,且初始污泥量越大恢复时间越短;受季节性的影响,反应器的运行工况应随水温的变化而及时调整。Under the condition of low temperature, after the state of activated bulking sludge observed, the problem of sludge bulking is solved through adjusting the running parameters of anaerobic-oxic reactor. Furthermore,the recovery approaches and steady and long-time running under the condition of room temperature are discussed. The result shows that the bulking sludge under the condition of low temperature has both the characteristics of filamentous bulking and non-filamentous bulking at the same time. The system＇ s recovery time under the condition of room temperature is 5 days shorter than that under the lower temperature. The aerobic sludge is much easier than the anaerobic sludge for the system recovery,and the more of sludge the easier. Because of the effect of different seasons, the running parameters of the reactor should be adjusted in time along with the water temperature.
