Comprehensive waste soda ash residue recycling method

The invention discloses a comprehensive waste soda ash residue recycling method. The comprehensive waste soda ash residue recycling method comprises the following steps: preparing a treatment solution; mixing a waste soda ash residue and the treatment solution for a stirring reaction; performing solid-liquid separation for recycling precipitated barium sulfate; recycling light calcium carbonate; recycling agricultural-grade ammonium chloride, industrial crude salt sodium chloride or potassium salt. By the comprehensive waste soda ash residue recycling method, the waste soda ash residue is comprehensively recycled, so that zero discharge of the waste residue and waste water during soda ash production is achieved; an alkali residue treatment technology is simple in flow path, low in investment, quick in effect, low in treatment cost and considerable in benefits. 本发明公开了种纯碱废渣综合回收利用的方法，包括处理液的配制；纯碱废渣与处理液的混合搅拌反应；固液分离回收沉淀硫酸钡；回收轻质碳酸钙；回收农业级氯化铵、工业粗盐氯化钠或钾盐，全面地对纯碱废渣进行回收处理，实现纯碱生产零废渣废水排放，碱渣处理工艺流程简单，投资少见效快，处理成本低，收益可观。
