研究了将O-A-O处理工艺和活性炭H.S.B菌种生物处理法相结合的处理高浓度焦化废水的新工艺，该工艺利用该菌种中的好氧菌、厌氧菌在曝气和厌氧工艺阶段中发挥的不同作用使废水得到处理。结果表明，COD为7440mg/L的焦化废水经过6h的初次曝气SBR工艺处理后，废水的COD去除率可达到47％。24h的厌氧SBR工艺处理后废水的COD去除率为78％。最后经过32h的二次曝气SBR工艺处理后，最终出水的COD为492mg/L，总的去除率达到94％。该工艺具有运行成本低和COD去除率高的特点。

A new process for the treatment of high concentration coking wastewater which uses high solution bacteria (H.S.B) and oxic-anoxic-oxic (O-A-O) processing in a sequential batch reactor (SBR) is described. The process is based on the ability of H.S.B. to decompose organic matter. The oxicbacteria and anoxicbacteria in H.S.B. fulfill different functions in the oxic SBR and anoxic-SBR steps.The results showed that the COD was reduced by 47% after coking wastewater with an initial COD of 7440mg/L was treated for 6h by oxic SBR. COD reduction of the resulting effluent reached 78% after a second 24h anoxic-SBR step. After a final 32h oxicSBR step, the COD of the effluent was 492mg/L, representing a reduction of over 93%. The process provides a very economical and effective method of reducing COD.
