活性污泥法处理丙烯腈废水存在的问题及其控制措施

The Problems in the Treatment of Acrylonitrile Wastewater by Activated Sludge and Its Control Measures

对活性污泥法处理丙烯腈废水的运行过程中存在的污泥膨胀、污泥上浮、曝气区产生泡沫及"死泥"等问题进行分析,深入剖析了产生这些问题的原因及影响因素,探讨了解决上述问题的控制对策。通过采取调控运行过程的水温、pH值、溶解氧等措施,可有效避免活性污泥法处理丙烯腈废水过程的污泥异常现象。

Through the analysis of sludge bulking,sludge floating,foam and dead mud in the aeration zone of activated sludge treatment process,the paper further expounds the causes of these problems and their influencing factors.After discussion of its control method,the reasons of the problems mentioned above are analyzed and its solutions finally find out.Measures such as adjusting the temperature,pH and dissolved oxygen of the water can effectively avoid the abnormal occurrences in treating acrylonitrile wastewater process by activated sludge.
