MVR蒸发技术在冶金工业废水零排放中的应用

MVR used in metallurgy zero discharge of industrial wastewater

介绍MVR蒸发技术的主要设备及工作原理,阐述其是一种对外界能源需求少的新型高效节能的蒸发技术。文章以韶关冶炼厂废水处理工程为例,探讨了采用MVR蒸发技术处理冶金工业废水的可能性,该厂首先对工业废水进行反渗透等膜浓缩后,采用机械蒸汽再压缩(MVR)技术对其进行蒸发、浓缩、结晶,实现媒介中的水和无机盐分离,最终达到冶金工业废水零排放。

Introduction MVR evaporation technology works, elaborated which is less a need for external energy new energy efficient evaporation technique. Taking Shaoguan metallurgical industry wastewater treatment works, for example, to explore the possibility of using MVR evaporation technology to process metallurgical industrial wastewater, After the first industrial plant wastewater reverse osmosis membrane concentration using mechanical vapor recompression (MVR) technology its evaporation, concentration, crystallization, to achieve the water and inorganic salts medium separation, metallurgical industry and ultimately achieve zero discharge of wastewater.
