Application research on the treatment of refractory organic wastewater by chlorine dioxide catalytic oxidation

简述了二氧化氯(ClO2)的性质与催化氧化原理,介绍了ClO2催化氧化法处理难降解有机废水的工艺条件、处理效果及优点。ClO2催化氧化处理难降解有机废水工艺简单、操作方便,不产生有机卤代烃等二次污染物、氧化能力持久,且在削减COD的同时极大地提高了废水的可生化性,使之能够更好地进行生化处理。

The properties and catalytic oxidation principle of chlorine dioxide are described simply. The process conditions, treatment efficiency and merits of the treatment of refractory organic wastewater by chlorine dioxide catalytic oxidation are introduced in detail. The process of chlorine dioxide catalytic oxidation is simply and easy to be operated and does not produce secondary pollutants such as organic halogenated hydrocarbons. Its oxidation capacity is permanent. It reduces COD and simultaneously raises the biochemical capacity of wastewater greatly, which makes the wastewater easier to be treated biochemically.
