摘　　要：为寻求一种不经稀释而直接处理焦化废水的途径,本文介绍了在OAO工艺中投加HENGJIE高效菌和粉末活性炭降解高浓度未稀释焦化废水的中间试验。试验结果表明:该方法可以处理未稀释的高浓度焦化废水,且系统启动快,降解效率高,CODcr去除率达93.16%,氨氮去除率达98.74%。HENGJIE高效微生物对焦化废水中有毒有害物质具有很高的耐受能力,并可降解一些常规微生物难以降解的有机物。To find a method for the direct treatment of coking waste water without dilution, a pilot test for adding HENGJIE high -efficiency bacterium and powder active carbon in OAO process to degrade the high concentration coking waste water without dilution is described in the paper. The test result shows that this method can treat the high concentration coking waste water without dilution and the system is characterized by quick start and high - efficiency degradation. Its removal rate of CODcr is up to 93.16% and NH3- N removal rate up to 98.74%. HENGJIE high- efficiency microorganism has high resistance to the poisonous and harmful matters in coking waste water and can degrade the organic matters that are difficult to be degraded with conventional microorganism.
