摘　　要：叙述了重碱助滤剂的作用机理,助滤剂在重碱过滤中的应用以及效益分析。试用结果表明,使用助滤剂用量少,降水效果好,经济收益高,可以在重碱过滤中大量使用。每吨纯碱添加0.25～0.35 kg助滤剂时,重碱滤饼水可下降3%左右,可为企业产生较大的经济效益。每吨纯碱添加0.6 kg助滤剂时,反而增加了重碱滤饼水分,经济效益下降。The action mechanism of the heavy alkali filter aid, the application and economic benefits of filter aid in heavy alkali filtration were described in this paper. Trial results showed that the filter aid could be widely used in heavy alkali filter for the reasons of less dosage, good effect and high economic benefits. The filter cake moisture content of heavy alkali decreased about 3% for every ton of soda ash adding 0.25 - 0.35 kg filter aid agent, which could produce great economic benefit for the enterprise. For every ton of soda ash adding 0.6 kg filter aid, the filter cake moisture content of heavy alkali would increase and the economic benefits declined.
