渗透法处理高盐废水的原理及工艺

高浓度含盐废水的主要处理方法有反渗透、离子交换、蒸馏等,目前处理成本比较高.为改变当前高盐废水处理成本居高不下的现状,受渗透的基本原理启发,以分析渗透法处理高盐废水的基本原理为基础,提出渗透法处理高盐废水的新工艺.以溶质氨的设计溶液为例,分析高盐废水处理的新工艺流程及工艺的可行性,并对比反渗透工艺,详细阐述新工艺的特点.经计算分析认为,基于渗透原理的高盐废水处理工艺可降低高盐废水的处理成本,可作为高含盐废水处理方法的一个新的研究方向.

Principle and Technical Process of Osmosis Method in High Concentration Salty Wastewater Treatment

This article briefly introduced principle of osmosis method and initiated a new theoretic technical precess in high concentration salty wastewater(HCSW)treatment based on osmosis principle in order to provide a tradeoff solution of such wastewater treatment.Taking am- monia as a design solution,a new technical process of HCSW treatment were discussed,as well as its application feasibility and benefits,com- pared with the reverse osmosis process of theses relevant wastewater.In general,it is interesting prospective that the new technique of HCSW treatment based on the osmosis principle,owing to its advantages,that is,tradeoff solutions in wastewater treatment.
