A/O和A~2/O工艺对膜生物反应器处理焦化废水影响的研究
Influence of A/O and A~2/O process on coking wastewater treatment in membrane bioreactor
摘要
Abstract
In order to investigate optimum process,anoxic-anaerobic-oxic (A~2/O) and anoxic-oxic (A/O)process were applied to treat coking wastewater in membrane bioreactor (MBR),pollutant removal rate was ana-lyzed,and membrane fouling was studied. The results showed that the removal rate of phenol,NH_3-N,COD was 99%,90% and 95% respectively using A~2/O process. By contrast,it was 97%,75%,93% respectively with A/O process. The NH_3-N removal rate of former was obviously superior to that of later,the denitrification rate of A~2/O was maintained in the range of 50% ~ 70%,which was better than that of A/O. Analysis of membrane fouling indicates that influence of operating mode on the membrane fouling was not obvious,the permeate flux decline with A~2/O reached 59%,while it was 56% under A/O. It could be seen that A~2/O process had an ad-vantage over A/O process.关键词
