摘要
脱硫废水一直以来都是困扰各个火力发电厂的难题,虽然每日排放量较少,但危害性极大.基于此,提出采用MF-NF全膜系统与电解法联用的方式处理脱硫废水,经过微滤纳滤处理后,可去除绝大部分重金属离子和大量高价离子.同时,后续电解装置电解制氯生成NaClO杀菌剂,替代了循环冷却水系统中需要加入的杀菌剂,降低了一定的生产成本,有效解决了脱硫废水不易达到排放标准的难题.
Abstract
Desulfurization wastewater has always been a difficult problem for various thermal power plants.Although the daily discharge is small,it is extremely harmful.Based on this,a combination of MF-NF full membrane system and electrolysis method is proposed to treat desulfurization wastewater.After microfiltration and nanofiltration treatment,the vast majority of heavy metal ions and a large number of high valence ions can be removed.At the same time,the subsequent electrolysis device generates NaClO fungicides by electrolyzing chlorine,replacing the fungicides that need to be added to the circulating cooling water system,reducing certain production costs and effectively solving the problem of desulfurization wastewater not easily meeting discharge standards.
