| 摘 要： | 以深圳水库水为研究对象,采用二氧化氯与氯混合消毒剂进行消毒试验,探讨了二氧化氯和氯的静态衰减规律、副产物亚氯酸盐的生成规律以及混合消毒剂的持续消毒能力.结果表明,二氧化氯与氯的消耗主要发生在与水接触的初期,随后,衰减较好地遵循一级反应动力学方程,亚氯酸盐的生成量约为二氧化氯消耗量的39.7%～57.9%,同时,在极低消毒剂残余量下,混合消毒剂仍有较好的持续消毒能力.

| Abstract: | Experiments were conducted using raw water from She nz hen reservoir to study consumption of chlorine dioxide and chlorine,formation of chlorite,and disinfection efficiency.The results showed that the combinations o f chlorine dioxide and chlorine decays quickly at the beginning when contacted w ith samples,then the consumption rate follows the first order reaction-model,39 .7%~54.9% of chlorine dioxide consumption converted to chlorite.The combinations of chlorine dioxide and chlorine still give a good disinfection efficiency when the residual of chlorine dioxide and chlorine is low. |
