A/O 活性污泥系统与生物膜系统处理煤气废水对比试验研究

COMPARATIVE STUDY ON GAS GENERATION WASTEWATER TREATMENT BY A/O ACTIVATED SLUDGE SYSTEM AND BIOFILM SYSTEM

本文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煤气废水的处理效果。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时，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。

The performances of both A/O activated sludge process and biofilm process operating simultaneously under the same condition to treat gas generation wastewater were examined and the results show that biofilm process has better treatment effect and higher capability to resist shock loading. For the same pollution removal rate the hydraulic retention time (HRT) of biofilm process is shorter 7.5 hour than that of A/O process and easier to maintain.
