摘要: 反冲洗是生物活性炭滤池运行中的一个关键步骤, 合理优化反冲洗过程有助于改善
其整体运行性能。为此, 采用反冲洗废水的浊度、滤池运行中的水头损失变化、对有机物的去除效
果以及出水细菌数等指标, 比较分析了 4种不同的反冲洗方式对生物活性炭滤池运行效果的影响,
最终认为气水联合反冲洗更适合于生物活性炭滤池。

Abstract: Backw ash ing process is a critica l step in the operation o f b io log ica l activated carbon
( BAC ) filter. Optim ization of backw ashing process is favorab le to the im provem ent of operation perform-
ance as a who le. Therefore, the evaluative indexes such as backw ash ing w astew ater turb id ity, variation in
head loss, rem oval o anic po llutants, and bacteria count in treated w ater are used pare and an-
alyze the effect of four different backw ash ing m ethods on the operation of BAC filter. It is be lieved tha t
a ir-w ater backw ashing is m ost suitab le fo r the filter
