KMnO4和MnSO4联用处理微污染原水试验研究

KMnO4和MnSO4联用处理微污染原水在一定程度上解决了单纯使用KMnO4在高投量时残余量产生的色度问题和低投量时处理效果不理想的问题，KMnO4和MnSO4联合使用能有效的去除水中有机物和浊度，并对KMnO4投量，KMnO4／MnSO4的最佳投量摩尔比，KMnO4预氧化时间，混合药剂反应时间以及投量对处理效果的影响等进行了一定的研究。

An experimental study of using KMnO4 and MnSO4 together to deal with the micro-pollution in raw water

Using KMnO 4 and MnSO 4 together to deal with the micro pollution in raw water may to some extent solve the problems of the color of water because of the residuum of KMnO 4 which is in high dosage and the unsatisfied result because of using a mall amount of KMnO 4.The combination of KMnO 4 and MnSO 4 may effectively remove the organic materials and turbidity in water.When the dosage of KMnO 4 is fixed at 1mg/L,the best dosage molar ratio of KMnO 4 and MnSO 4 is 0 88~1 17(that is,the residuum of KMnO 4 is 0.19~0.39mg/L).The time of pre oxidation and the reaction time of chemicals and proper dosage have certain effect on the removal results.When the composite chemicals reaction lasts 10min,the removal effects are better than that of only using KMnO 4.In addction,the combination of KMnO 4 and MnSO 4 may reduce the amount of coagutant dosage,and the turbidity is <3NTU under experimental condition.In this way,the consumption of chemicals may reduce to 75% compared with APC used alone.
