重金属废水的处理方法

Treatment Methods for Heavy Metal Wastewater

近几年,随着工业化的飞速发展和城市化进程的加快,越来越多工业废水未经认真处理就肆意排放,造成了水域、土壤和环境的重金属污染,如何减少重金属对环境的污染是当今环保学者和科研工作者的一个重要课题。介绍了重金属废水的来源、危害,及传统的处理方法,并对未来重金属废水处理新技术进行了展望。提出生物法去除废水中的重金属有良好的应用前景,应综合运用各种技术以实现水资源和重金属的双重回收。

In recent years, with the rapid development of industrialization and the urbanization, more and more industrial wastewater is arbitrailly discharged without careful treatment , resulting in heavy metal pollution of water, soil and environment.How to reduce the pollution of heavy metals to environment is an important subject for environmental scholars and researchers.The origin, the harms of heavy metal wastewater traditional, treatment methods were introduced, and treatment new technologies of heavy metal wastewater were prospected. It is pointed out that biologieal method used for treating heavy metal in wastewater proposed has a good application prospect, a various techniques should be comprehensive used to achieve the double recovery of water resources and recycling of heavy metals.
