摘要: 随着国家环保政策的实施,火电厂废水零排放势在必行。火电厂废水零排放工作分为深度节水和末端废水固化处置2个阶段。基于此,对不同类型电厂的典型深度节水技术路线进行了分析,并指出了问题所在;同时,对目前末端废水固化处置方法进行了技术经济比较。在考虑超低排放改造、脱硫工艺用水水质、脱硫废水水质水量和循环水系统的腐蚀结垢等多种因素后,提出了火电厂废水零排放技术路线制定的相关建议。

关键词: 火电厂, 废水零排放, 深度节水, 末端废水固化, 超低排放

Abstract: The implementation of zero liquid discharge(ZLD) of fossil-fired power plants is becoming inevitable in compliance with the national environmental policy. ZLD of fossil-fired power plants is divided into two stages, i.e., advanced water-saving and terminal wastewater solidification. This article analyzes the advanced water-saving technical routes and proposes the existing problems in various types of power plants. Meanwhile, the article conducts the technical and economical comparison on the current terminal wastewater solidification methods. By taking account of multiple influencing factors, such as ultra low emission of flue gas pollutants, desulfurization process water quality, desulfurization wastewater quality and quantity, corrosion and fouling of circulating water system, etc., the article also puts forward some suggestions on the determination of ZLD route for fossil-fired power plants.

Key words: fossil-fired power plant, zero liquid discharge, deep water saving, terminal wastewater solidification, ultra low emission of flue gas pollutants
