摘要: 研究生产亚氯酸钠时产生废液的综合利用, 包括确定其硫酸和硫酸氢钠的含量, 用氢氧化钙、 氧化钙和氢氧化钡与废液反应生成硫酸盐. 制定了用氧化钙与废液进行反应的生产工艺和使用设备, 使废液经处理后成为硫酸钠溶液和石膏.

关键词: 废液, 环境, 硫酸, 综合利用

Abstract: This article deals with the research of the liquor which was produced in the production of sodium chlorite by mixing it with some kinds of materials such as CaO and Ca(OH)2 to calculate the amounts of sulphuric acid and sodium hydrogen sulfate in the waste liquor. At last it introduces a method to make use of this liquor to produce Na2SO4 and CaSO4.

Key words: waste liquor, environment, sulphuric acid, compositive application
