摘要
In order to prove the effect of bromate formation by chlorination in drinking water treatment process, by carrying out laboratory chlorination test in simulated water, Harbin drinking water and the Songhua River raw water samples, the influences of bromine ion be oxidated into bromate by chlorine were investigated. The results showed that when chlorine quantity was 5 mg/L, the conversion rate of bromide ion to bromate was less than 1.3%. On a large amount of chlorine (5 mg/L), significant bromate generation changes could not cause by the long-term existence of chlorine in the water, and the bromate concentration did not change significantly for a long period of time. In the conditions of high concentration of organic matter in water, the risk of bromate formation was low. When chlorine content reached 5 mg/L, a very small amount of bromate was detected in the raw water. New excessive risk caused by the presence of residual chlorine would not exist in the process of water supply.
