摘要
采用臭氧氧化分别与混凝、活性炭吸附联用处理,对镁离子随有机物的去除而损失进行分析.结果表明,单独臭氧氧化不能有效去除高盐量水中的有机物.通过GC-MS分析和荧光检测,指出臭氧氧化改变了水中有机物的结构特征,增加了水中羧酸类有机物含量,从而导致镁离子与其发生络合配位.当这些有机物通过混凝或者活性炭吸附被去除时,与其发生配位的镁离子也会随之从水中损失.
This paper mainly analyzed the mechanism of magnesium ion loss along with the removal of organc matter in high-concentrated saline water by ozonation only, ozonation followed by coagulation and activated carbon adsorption. The results showed that ozonation can＇t effectively remove the organic matter. Through GC-MS and fluorescence analysis, it indicated ozonation can change the structure of organic matter, increasing organic matters which contained carboxylic groups, and hence resulted in the complexation with magnesium ion. So that magnesium ion would be lost along with the removal of organic matters by coagulation or activated carbon adsorption following ozonation.
