Abstract: Experiments were conducted by using raw water from a reservoir of south China to study consumption of chlorine dioxide and formation of chlorite. The results show that chlorine dioxide decays quickly in the beginning in samples, then the consumption is constant in first ordermodel. 39.7%～57.9% and 48.0%～70.0% of chlorine dioxide consumption are converted into chlorite by means of the combinations of chlorine dioxide and chlorine, and pure chlorine dioxide, respectively. And the amount of chlorite formation is lower as micropolluted raw water is treated by the comlinations.

Key words: chlorite, micropolluted raw water , chlorine dioxide
