摘要
介绍了纯碱生产中废液废渣的开发利用途径、措施、工艺方法与原理 ;探讨了用废液制氯化钙和再制盐、盐水一次泥制轻质碳酸镁、用盐水一次泥进行烟气脱硫、从二次盐泥中提取特种碳酸钙 ,废渣制建筑材料等综合利用情况。
The approach to utilizing waste liquid and waste residuce,priciple of production,and technolo-gical requirements were presented.This paper discusses its feasibility from the comprehensive utilization point,which covered making CaCl 2 and reproducing salt by wasted liquid,making MgCO 3 from the first mud of salt,Desulphurizing of flue gas with the first mud of salt,drawing special CaCO 3 from the second mud of salt,and making architectural material from waste residuce ect.
