摘要: 利用四室膜电解反应器处理含有BSA、Na2SO4和NaCl的模拟含盐有机废水。通过实验发现膜电解反应器的脱盐率可达到90%左右,同时具有对酸的浓缩效果,但大分子有机物在电场的作用下会带有负电,发生有机物的定向移动造成阴离子交换膜的污染,影响离子的脱除和浓缩效率,同时发现Cl-比SO42-更容易被分离。

Abstract: The four-chamber membrane electrolytic reactor has been used for treating simulated saline organic wastewater containing BSA, Na2SO4 and NaCl. It is found through experiments that the desalting rate of the membrane electrolytic reactor can reach about 90% and has concentrating effect on acid,but macromolecular organics may have negative electricity under electric field effect,and the occurrence of organics directional movement results in the pollution of negative ion exchange membrane,affecting the removal and concentration efficiencies of ions. At the same time,it is found that compared with SO42-, Cl-is easier to be separated.
