摘　　要：二氧化氯在对水体中有机物进行强氧化反应的同时,其在短时间内也会和水体中杂质产生反应,形成氯酸盐和亚氯酸盐等无机消毒副产物。根据GB 5749—2006《生活饮用水卫生标准》的规定,氯酸盐、亚氯酸盐最大允许值为0.7 mg/L,并作为常规检测指标每月开展检测,所以在水厂的管理过程中要严格做好二氧化氯消毒剂的投加量,既要保证杀菌性能达到预期,又要严格控制氯酸盐、亚氯酸盐消毒副产物的产生。因而在生活饮用水的制水过程中要切实做好水质管理工作,同时开展二氧化氯消毒副产物和菌落总数的检测工作,文章分析了目前国内主要的二氧化氯消毒副产物的检测方法,对比寻找合适于各水厂的检测方法,切实保障饮水安全。Chlorine dioxide strongly oxidizes organic compounds in water,and it will also react with impurities in water in a short time,forming inorganic disinfection by-products such as chlorates and chlorates.Under GB 5749—2006“The Sanitary Standards for Drinking Water”,the maximum allowable value of chlorite and subchlorite is 0.7 mg/L,and as a regular testing index to carry out monthly testing.Therefore,in the management process of water plant,the dosage of chlorine dioxide disinfectant,to ensure that the sterilization performance meets the expectations,and to strictly control the production of chlorate,chlorite disinfection by-products.Therefore,in the process of drinking water water production to effectively do a good job of water quality management.At the same time,the byproducts of chlorine dioxide disinfection and the total number of bacteria.This article analyzes the main test method of chlorine dioxide disinfection,f ind suitable testing methods for each water plant,we will effectively ensure the safety of drinking water.
