BI Chong-yu1 LI Ri-qiang2 JIN Guo-wen3 (1.Brigade of Supervision and Law-enforcement for Safe Production of Shanxi Province Taiyuan 030012)  
Coking wastewater is difficult to be treated with extraordinary complicated components.In this paper,it was treated by the method of MSBR,and the treatment effects in the different reaction stage(anoxic tank,anaerobic tank,aerobic tank and SBR effluent) in 5 hydraulic retention times(66 h,39 h,28 h,20 h,17 h) were studied.The results showed that under the condition that the HRT was 66 h,the best effect was obtained with the 82% removal rate of CODCr.Moreover,the CODCr concentration of each HRT group is greatly removed in the anoxic tank and anaerobic tank(A2) which are proposed in front of MSBR system. Because of the nitrification was inhibited,the removal effect of NH3-N was not obvious.
