Disposal of 3.5-dinitro-benzoicacid Wastewater by Semi-Coke/Ozone Combined Technology

Abstract:

The effects of pH, initial concentration, ozone flow, temperature and semi-coke dosage on 3.5-dinitro-benzoic acid wastewater in the process of carbocoal catalytic ozonation are investigated. The results show that: the removal rate of COD increases with the rise of ozone flow and reaction time in a certain range; temperature has little effect on the removal rate of COD; the removal rate of COD achieve the maximum value when the pH is about 12; the COD removal rate of carbocoal catalytic ozonation is obviously better than single ozonation.
