含砷废水修复技术的研究现状和展望

摘要

Arsenic is a contaminant to be controlled preferentially in China. The repairing of arsenic-containing wastewater is of great significance in enhancing environmental quality and assuring the safety of farm products. Aiming at the resources, amount and harm of arsenic-containing wastewater, the development of various new arsenic-removing techniques is reviewed, including physical, chemical and biological methods in order to provide reference for developing and utilizing repairing techniques in practical production.%砷在我国是优先控制的污染元素.治理含砷废水对于提高环境质量,保证农产品安全具有重要意义.作者针对国内外含砷废水的来源、数量和污染危害情况,综述了近年来各种除砷新技术的研究进展,内容包括物理、化学及生物除砷的主要技术,以期为在实际生产中开发和利用修复技术提供参考.
