Treatment of Organic Compounds in Radioactive Wastewater by Ozonation

Article Preview

Abstract:

The organic compounds in radioactive wastewater were treated using ozone oxidation technology. The influence of pH, ozone dosage, reaction time, initial COD, H2O2 on the removal of COD by ozone was investigated. The results showed that the removal efficiency of COD in the alkaline condition was higher than that of acidic condition, the COD removal rate increased with increasing ozone dosage, reaction time, H2O2 dosage, decreased with increasing initial COD. Under the conditions of COD 362 mg/L, pH value 9.0, ozone dosage 7.86 mg•L-1•min-1, reaction time 30 min , the removal rate of COD was 25.9%; the removal rate of COD increased to 37.8% when 0.2 ml H2O2 was added in addition.
