高锰酸钾和预臭氧强化常规处理工艺

Potassium Permanganate and Ozone Pre-oxidation for Enhancing Conventional Treatment Process

针对天津饮水水源的水质特点,研究了高锰酸钾和臭氧的预氧化效果以及对后续气浮、过滤处理效果的影响。结果表明,预氧化能提高后续处理工艺的出水水质,降低出水浊度和高锰酸盐指数。经预氧化后,水中含有羧基、羟基的有机物含量增加,从而改善了有机物的可混凝性,这是处理效果提高的根本原因。

In accordance with the characteristics of drinking water source in Tianjin, study was made on the effect of potassium permanganate and ozone pre-oxidation, and their influence on the subsequent air flotation and filtration treatment. The result indicates that pre-oxidation can improve the quality of treated water from the subsequent process, and reduce turbidity and permanganate index. After pre-oxidation, the content of organic matters containing carboxyl and hydroxyl will be increased, and thus improving the coagulability of organic matters, which is the main cause for improvement of treatment effect.
