Potassium Permanganate/ Ozone Combined oxidation for Minimizing Bromate in Drinking Water

摘要：

In this study,experiments were conducted to make a comparison in bromate formation between KMnO4/O3 combined oxidation and single ozonation.The effect of KMnO4 dosage,temperature,pH and NOM on bromate formation during KMnO4/O3 combined oxidation was investigated.Result shows that,bromate formation is 26％ lower during the process of KMnO4/O3 combined oxidation.The optimal KMnO4 dosage is suggested to be lmg/L considering balance between bromate inhibition and the residual manganese concentration.When KMnO4 dosage was l.0mg/L,initial bromide concentration was lower than 80 μg/L,and temperature was below 25℃,combined oxidation can make the formation of bromate under the maximum contaminant level of 10 μg/L.Finally,the probable mechanism of the better behavior of KMnO4/O3 combined oxidation was discussed.
