摘要
本文就皮革化工厂硫酸化油生产中的盐洗／盐析提出改进方法，以硫酸钠代替氯化钠。盐洗废液循环使用，这样降低了废液排放量，减少对环境的污染。
he improved methods replacing sodium chloride with sodium sul-fate in the sait-washing and salting out processes for producing sulfat-ed oils in leather chemical works, were given in this paper,which al-lovwed the reuse of the residual salt-washing bath.As a result,thereductions of effluent volumes,as well as,environment pollutions maybe seen.
