刍议多效蒸发处理含盐化工废水的进展

随着中国市场经济的发展,各种工业项目如雨后春笋般在中国各地兴起,随之而来的是给生态环境带来的巨大压力。化工项目一般都伴随着废水、废气、固废的产生。其中废水的排放尤其要引起重视,近年来国内很多研究人员都在研究含盐化工废水的回收利用。文中围绕多效蒸发处理含盐化工废水的技术工艺展开论述,对国内在多效蒸发技术方面的应用进展进行简要概述。

Study on theTreatment of Saline Wastewater by Multi-effect Evaporation

With the development of market economy in China,various industrial projects are spring up all over China,which brings great pressure on the ecological environment.Chemical projects are generally accompanied by the production of wastewater,waste gas and solid waste,and the discharge of wastewater is of particular concern.In recent years,many domestic researchers have been studying the recycling of salt-containing chemical wastewater.In this paper,the technology of multi-effect evaporation for the treatment of salt-containing chemical wastewater is discussed,and the application of multi-effect evaporation technology in China is briefly summarized.
