有色金属冶炼高含砷污酸除砷技术研究现状

有色冶炼过程中会产生大量的含砷酸性废水,除砷处理给企业生产运行带来了较大的压力,随着近年来冶炼废水中的砷含量逐步升高,高含砷污酸除砷处理受到了广泛的关注,如何实现经济、高效除砷成为当前的研究热点。对近年来高砷污酸处置技术：硫化法和石灰中和-铁盐法进行了总结与分析。并对尾渣固化除砷技术进行了归纳与展望。短期内硫化法除砷技术仍然为最受欢迎的主流技术,尾渣固化法在砷固定方面有较大优势,但应用过程中收到实际生产过程的制约,因此,该方法有较大的研究前景。

A review of arsenic removal technology from non-ferrous metal smelting wastewater with high arsenic content

A large amount of arsenic-containing acid wastewater will be produced in the non-ferrous smelting process, which will bring pressure to the production and operation of enterprises. With the gradual increase of arsenic content in Smelting Wastewater in recent years, acid arsenic removal treatment of high arsenic containing wastewater has attracted extensive attention. How to achieve economical and efficient arsenic removal has become a current research hotspot. The treatment technology of high arsenic-containing wastewater and the emerging arsenic removal technology of tailings solidification are summarized and prospected, In the short term, the sulfidation method is still the most popular mainstream technology; the tailings solidification method is restricted by the actual production process in the application process, but this method has great research prospects.
