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.

Study on the Collaborative Degradation of Acid Red B Dye Wastewater by O₃/H₂O₂

“…There are prevalence problems of high dosing volume, low utilization rate. In order to improve the speed and efficiency of ozone oxidation, it is focusing on this technic combined with catalytic ozonation or adsorption [6][7][8] .…”
