摘　　要：本文研究了利用Na_2SO_4替代Na_2CO_3参与粗盐水精制的可行性。研究了Na_2SO_4加入量、灰乳及Na_2SO_4加入方式对除钙效果的影响;探讨了除镁盐水中Ca2+浓度对结疤的影响及CaSO_4结疤的消除。The feasible of using sodium sulfate substitute for soda ash in the process of the brine purity. The effect of removing calcium was studied by adding sodium sulfate,carbonation and method of sodium sulfate, effects of calcium concentration and liminating measures of scaling were discussed.
