水中有机物臭氧化去除反应机理

THE REACTION MECHANISM OF ORGANIC SUBSTANCE REMOVAL FROM WATER BY OZONIZATION

随着臭氧化在水处理技术中应用日益增多,研究臭氧化去除水中有机物的机理日显重要。本文在介绍了决定水中臭氧化反应速率的二种反应,即直接反应和间接反应的基础上,着重讨论了芳族化合物、烯烃化合物、环状烯烃化合物,苯酚、苯、苯胺、硝基芳烃、喹啉、二甲基4氯酚氧基醋酸、油酸、有机硫磷化合物,甲醇、甲醛、甲酸和马拉硫磷等与臭氧的反应机理。

With the growing interest in ozonization practice as applied in water treatment, it becomes important to study the reaction mechanism of organic substance removal from water by ozonization.In this paper, it is described that two possible pathways determine the rate at which the chemical reaction proceeds. These different pathways are the direct reaction and the indiret reaction. Then the ozonization mechanism of aromatics,olefins, cyclic olefins, phenol, benzene, aniline, aromatic nitro compounds, quinoline, MCPA, oleic acid, nucleophiles, methanol, formaldehyde, formic acid, and malathion in water is discussed.
