摘　　要：采用ClO_2三相催化氧化工艺对焦化污水二沉池出水的处理进行了中试研究,考察了进水量、供气量、加药量等参数对焦化污水COD处理效果的影响,得出的最佳工艺条件为:进水量0.2 m^3/h,有效催化剂用量0.5 m^3,供气量10 m^3/h,盐酸投加量60 m L/h,氯酸钠投加量30 m L/h。最佳工艺条件下,平均出水COD为44 mg/L,平均去除率为80.3%,能达到国家一级排放标准。The process of ClO_2 catalytic oxidation is used to treat the coking wastewater. In this pilot research,the effects of water inflow,dosage,air demand of coking wastewater treatment on COD are investigated and the optimum ranges for catalytic oxidation are found out,water inflow of 0. 2 m^3/ h,effective catalyst of 0. 5 m^3,air demand of 10 m^3/ h,dosage of hydrochloric acid is 60 m L / h and dosage of sodium perchlorate is 30 m L / h. Under this condition,the average effluent COD is 44 mg / L and average removal rate is 80. 3%,which can meet the requirements of the national discharge standard.
