A/O活性污泥系统与生物膜系统处理炼焦工业废水对比试验研究

Comparative study on waste water treatment by A/O activated sludge system and biofilm system

考察了在相同的运行条件下,A/O活性污泥系统和生物膜系统对炼焦工业废水的处理效果。试验结果表明,生物膜系统的抗冲击负荷能力强,处理效果优于A/O活性污泥系统,达到相同污染物去除率,生物膜系统的总水力停留时间缩短了7.5h,而且运行管理简单。

Under the same operating conditions, comparison tests of coke oven sewage treatment through A/O activated sludge and biological membrane systems are done, The results indicate that shock resistance of biological membrane is stronger, its treatment effects are better than that of activated sludge, Achieving the same removal rate for identical pollutant, hydraulic retention time of biological membrane is reduced by 7,5 hours, Moreover, its operation and management are very simple.
