准液膜法处理含铬废水影响因素的实验研究

Research on influencing factors in handling wastewater containing Cr(Ⅵ) with pseudo liquid membrane method

本文利用自制的不同浓度的酸性重铬酸钠溶液为合成废水,对准液膜法处理含铬废水影响因素进行了实验研究,发现碱液下落状态和酸度、提取次数是影响准液膜法处理含铬废水的主要因素。

With pseudo liquid membrane method, Cr (Ⅵ ) was extracted from the wastewater, which was com-posed of a variety of concentraction of Sodium dichromate in acidic aqueous Solution. The paper studies the infuenc-ingfactos of handling wastewater containing Cr (Ⅵ ) by pseudo liquid membrane Method, finds that base solution sprys: falling and acidity and sampling times are the major influencing factors.
