摘要

对纳滤膜技术处理火力发电厂循环冷却排污水做了简要介绍。纳滤可有效地去除循环冷却排污水中的悬浮物和总硬度,降低含盐量,其中总溶解性固体和总硬度的去除率达到 90 %以上,含盐量去除率达到 80 %以上,处理后的水质符合工业用水和循环水补充用水的水质要求。纳滤膜处理循环冷却排污水在技术上是可行的,处理后的水可回用于电厂补给水系统,可以大大减少火力发电厂的耗水量和工业废水排放量,达到节水和“零”排放的目的。

Abstract

T he nanof iltrat ing ( NF) membrane w hich has been used for treat ing the circulating cooling sew age inheat pow er plant s is int roduced briefly. NF can effect ly remove the suspended part icles, and low er the total hardnessand reduce the salt content in the circulating cooling sew age. The removal of the total disolved solid( T DS)and the total hardness are above 90%, and that of the salt content is more than 80%. T he quality of treated watercan meet the requirements of industrial use and supply ing water of circulating cooling. The treatment of thecirculat ing cooling sewage in heat pow er plant is feasible to use nanofiltrat ing membrane sof tening equipment.T he t reated water can be reused in supplying systems. It could great ly decrease water consumpt ion and drainagequantity of indust ry wastewater. It w as a promising technolog y for water-saving and zero discharge in the fuelpow er plant.
