对Ａ，Ｂ两种不同地表水源原水，在常规净水工艺中，应用二氧化氯和氯进行消毒对比试验．试验结果证明，二氧化氯的消毒效果优于同加注量的氯消毒效果．并指出使用二氧化氯消毒时，投加量应不超过１．４～２．０ｍｇ／Ｌ，才能保证剩余亚氯酸根低于１ｍｇ／Ｌ．
For A and B, two kinds of raw water for surface water sources, in the conventional water purification process, chlorine dioxide and chlorine were used for disinfection comparative tests. The test results show that the chlorine dioxide disinfection effect is better than the same amount of chlorine disinfection. And pointed out that when using chlorine dioxide disinfection, the dosage should not exceed 1.4 ~ 2.0mg/L, to ensure that the remaining chlorite is lower than 1mg/L.
