| 摘 要： | 针对采用改良氧化沟工艺的城市污水处理厂运行一年多来发生的化学泡沫、腐化浮泥、反硝化浮泥和老化漂泥等问题，分析了其各自产生的原因，并给出了解决方法。认为反硝化浮泥和老化漂泥是该厂易出现的污泥异常问题，可通过控制排泥量、污泥负荷和曝气量等运行参数加以预防控制。

| Abstract: | Aimed at the problems such as chemical foam, septic floating sludge, denitrifying floating sludge and aged floating sludge occurred in a municipal wastewater treatment plant using the modified oxidation ditch for more than one year, the causes for mentioned problems were analyzed, and the solutions were given respectively. It is considered that the common abnormal problems in this plant are denitrifying floating sludge and aged floating sludge which can be prevented by controlling some operation factors such as sludge output, sludge load and aeration rate. |
