曝气生物滤池处理化工污水研究

曝气生物滤池是80年代末在欧美发展起来的一种新型污水处理技术。它采用了一种新型粒状填料,综合了过滤、吸附和生物代谢等多种净化作用,具有占地小、出水质量好、流程简单、对环境影响小等诸多优点。文章介绍了曝气生物滤池生物膜的形成及净化机理,并取某石化公司化工污水处理厂调节池出水进行了实验,主要对水中COD、BOD、SS去除效果进行分析,结果表明:曝气生物滤池具有较强的抗冲击负荷能力,运转方便、设备简单。

Study on Chemical Sewage Treatment of Biological Aerated Filter Process

The formation of biological aerated filter (BAF) biofilm and its purification mechanism were introduced in this paper. Experiments were done in wastewater treatment tank of petrochemical company with BAF to analyze the removal effect of COD, BOD and SS. The result showed that the BAF was characteristic of high impaction resist, easy maintenance and simple facilities.
