摘要
本文介绍了某金矿选冶过程中产生的硫酸钠废水的电解综合利用试验结果,阐述了该硫酸钠盐水的预处理流程,探索了硫酸钠浓度、电流强度、膜材料种类等因素对电解效率的影响,通过电解工艺处理该废水,阴阳极分别产生氢氧化钠和硫酸溶液,可以直接回用于现场工业生产中,有利于矿山循环经济的发展。
This paper introduced the comprehensive utilization technologies of sodium sulfate waste water by means of membrane-electro-decomposition,which analyzed the feasibility of effecting factors on pretreatment process,such as feed concentration,electric current density,material of membrane etc. The wastewater treatment by electrolytic technology can produce sodium hydroxide and sulfuric acid solution respectively on anode and cathode. And the products can be directly used in the industrial process,which is conducive to the development of mining cyclic economy.
