摘要
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 process speeding up, more and more industrial wastewater without carelid treatment is wanton discharge, resulting in heavy metal contamination of water, soil and environment, how to reduce the pollution of heavy metals in the environment is an important subjec! in the present enviromnental scholars and researchers. Introduces the origin, the harm of heavy metal wastewater, treatment method and tradition, and the future of heavy metal wastewater treatment new technology is prospected. Heavy metal removal in wastewater by biological method proposed has good application prospect： to achieve the dual water resources and recycling of heavy metals should be comprehensive use of various techniques.
