水中邻苯二甲酸酯类化合物去除方法实验研究

Study on removement of phthalates in drinking water from municipal water supply system

目的 探讨水中邻苯二甲酸酯类化合物去除方法 ,并通过筛选确定有效去除工艺。方法 用标准贮备液配制实验溶液 ,采用 4种方法进行实验处理 ,对处理前后样品进行水质检验。结果 4种处理方法中Ⅳ法对 4种异构体的去除率为 10 0 % ;Ⅱ法为 0 %～ 10 0 %不等 ,而Ⅰ、Ⅲ法仅对邻苯二甲酸二酯有效果 ,去除率分别为 89 7%和10 0 %。结论 水中邻苯二甲酸酯类化合物去除效果Ⅳ法 >Ⅰ法 >Ⅲ、Ⅰ法 。

Objective To inquire into the method of removement of phthalates in drinking water and make sure of the effective treatmet technology by screen.Methods The test solution was compound of standard store for furture use liquid,and four methods were used to treat samples of all source water and finished water which were examined.Results Among the four treatment methods,number Ⅳ to PAE four deferent structure was 100%;number Ⅱ was 0%-100%;number Ⅰ?Ⅲ only removed DMP,removing rate were 89.7% and 100%.Conclusion The effect of four methods used in examining of drinking water was method Ⅳ>method Ⅱ>method Ⅲ and Ⅰ.Method Ⅳ was best to remove phthalates.
