ClO_2气液分离纯化器在饮用水消毒处理中的应用
|
摘要
主要概述了二氧化氯消毒无机副产物的来源和控制,介绍了与氯酸钠+盐酸工艺配套使用的二氧化氯分离纯化器的应用效果。该分离纯化器可实现二氧化氯及氯气与反应液的分离,不仅解决了出口溶液酸度过大的问题,而且可有效地避免由于反应不完全造成剩余原料氯酸根被带入水体的问题。
The sources and control of inorganic by-products from chlorine dioxide disinfection were summarized. The application effect of chlorine dioxide purifier with gas-liquid separation for supporting sodium chlorate and hydrochloric acid processes was introduced. The purifier could separate chlorine dioxide and chlorine from the reaction liquid,which solved the problem of excessive solution acidity and could effectively avoid surplus raw chlorate entering the water due to incomplete reaction.
