摘　　要：文章对氨碱法制碱废清液制取氯化钙生产工艺中硫酸根的去除方法进行了研究 ,试验证实采用浓氯化钙溶液与废清液预先兑合的方法 ,可将废清液中硫酸根含量降至0 0 2 %左右 。The removal method of SO 2- 4 in production of calcium chloride from waste liquid of ammonia-soda process was studied in the paper.The test proved that the content of SO 2- 4 in waste liquid can be decreased to 0.02% by mixing concentrated calcium chloride liquid and waste liquid.Therefore,calcium sulfate scale on the evaporator wall in the subsequent evaporation was reduced.
