摘要
介绍了含重金属酸洗漂洗废水的来源、组成及危害;分析了目前国内外治理酸洗废水常用方法、原理及优缺点;从资源化与综合利用角度考虑,指出重金属酸洗漂洗废水处理新技术研发中需着重解决的问题,即回收有价金属,实现工业废水内部循环,达到减排或零排放。
The source,composition and harmful effects of pickling rinse wastewater containing heavy metal ions are introduced.The present treatment technologies,principles,and advantages and disadvantages of the technologies are analyzed.With the consideration of reclamation and comprehensive utilization,some problems that should be considered with great concern in developing new techniques are put forward,such as recovering valuable metals,achieving interior circulation of industrial wastewater and reaching the goal of reducing emission or zero-emission.
