| 摘 要： | 采用AO和OAO工艺处理焦化废水并进行对比试验。结果表明,OAO工艺对COD、氨氮的去除率分别为85.55%和93.82%;AO工艺对COD、氨氮的去除率分别为78.57%和91.19%,OAO工艺优于AO工艺,但AO工艺的反硝化效果较好。对于高浓度焦化废水,宜采用OAO工艺,普通的焦化废水则宜采用AO工艺。

| Abstract: | The AO and OAO processes were used for coking effluent treatment, and the comparative tests were conducted. The results showed that the removal efficiencies of COD and NH3-N by means of OAO were respectively 85.55% and 93.82% ; and the removal efficienies of COD and NH3-N by means of AO were 78.57% and 91.19% respectively, OAO process is better than AO process, but the denitrification effect of AO process is better. As far as high concentration coking effluent is concerned, it is better to adopt OAO process, for normal c0king effluent, it is better to adopt AO process. |
