Abstract
Through comparing with the different of combination by flocculating, absorbing, catalytic oxidizing and the result of treatment to deal with coking wastewater ,have confirmed the combination of flocculation and absorption is the best craft, trying on the ridding of coagulate, the influence of pH and the addition of coagulate ,the addition of active carbon and so on. The result shows that, adopt the method of flocculation-absorption to deal with the second sink pool coking water, the COD reduced from 536 mg/ L to 96mg/ L, deal with the aeration-tank strengthen, the COD reduced from 1440 mg/ L to 92mg/ L, the removal rate of COD are 82.1% and 93.6%. After treatment, the wastewater becomes clear and can be recycled.
