摘要

火电厂含盐废水排放对环境污染严重

而单一常规的物理、化学、生物等水处理方法难以达到废水水质排放要求。本文根据火电厂水处理中存在的问题

结合国家对火电厂废水零排放方面的最新政策

分析了燃煤电厂中含盐废水水质特点

着重介绍了燃煤电厂处理含盐废水的几种常用蒸发法以及蒸发结晶零排放技术

列举了蒸发结晶技术在燃煤电厂废水处理的应用

指出了喷雾结晶技术处理含盐废水的优势

为火电厂含盐废水处理及零排放提供参考。

Abstract

The discharge of saline waste water from thermal power plants has caused serious environmental pollution. It is really hard to meet the wastewater quality discharge standards by using of one single and conventional water treatment methods

such as a physical

chemical or biological method. In order to prevent the serious problems of water treatment existing in the thermal power plants

a series of government policy on the zero wastewater discharge are introduced and implemented. The characteristics of saline wastewater quality in thermal power plants are also briefly analyzed. Several common evaporation methods and zero liquid discharge crystallization processes for saline waste water treatment in coal fired power plants are mainly introduced. Some applications of evaporation crystallization technology are enumerated in coal fired power plant

then the advantages of spray crystallization technology in treating saline wastewater are also pointed out

and it makes such an important reference for the zero saline waste water discharge in thermal power plants.
