氯酸钠生产中母液处理工艺研究

Abstract

Abstract: Recently，chemical precipitation is used for treating sulfate radicals in the sodium chlorate production，but produces a considerable amount of sludge containing Cr，causing pollution to the environment.The use of ion exchange resin and nanofiltration membrane device integrated treatment of sodium chlorate industry crystallization mother liquor was presented.This method not only could recover sodium dichromate but also could remove sulfate radicals.Results showed that the recovery rate of sodium dichromate could reach 98%，and the content of sodium sulfate in the crystallization mother liquor was less than 3 g/L after treatment，reaching the recycling requirements.

Key words: ion exchange resin, nanofiltration membrane, sodium chlorate, sodium sulfate
