In this paper, analyses were made on the variation of the absorbency, TOC, pH and acute toxicity of the simulated wastewater which contains Acid brilliant blue G in the ozonization process. The intermediate products of the dye ozonization process were detected with GC/MS analysis method. The result showed the ozonization process contains two stages, the decoloring stage and the deep degrading stage...
Apilot scale test of advanced treatment of ethene wastewater by ozonization was carried out for industrial water reuse. Effects of different operating conditions on COD degradation, such as wastewater flow rate, ozonized gas flow rate, operating voltage of ozonizer and two ozone generation means, using pure oxygen or air, was investigated. The results show that the increase of ozonizer operating voltage,...
