水体中砷离子去除方法综述
|
摘要
长期以来,我国工业化进程持续推进,给环境造成不可估量的压力。其中,采矿业、矿物加工业、冶金作业以及农业生产造成水体出现砷污染现象。企业要选取有效的除砷技术,以提升出水质量。因此,本文分析了化学法、物理法、生物法等方法,以便有效去除水体中的砷离子。
For a long time, China's industrialization process has continued to advance, causing immeasurable pressure on the environment. Among them, mining, mineral processing, metallurgical operations and agricultural production have caused arsenic pollution in water bodies. Enterprises should choose effective arsenic removal technology to improve the quality of the effluent.Therefore, this paper analyzes chemical, physical, biological and other methods to effectively remove arsenic ions from water.
