| Abstract: | The process of ClO2 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 m3/h ,effective catalyst of 0 .5 m3 ,air demand of 10 m3/h ,dosage of hydrochloric acid is 60 mL/h and dosage of sodium perchlorate is 30 mL/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 . |
