铅锌冶炼废水铊污染治理技术研究

Study on Treatment Technology of Thallium Pollution in Lead Zinc Smelting Wastewater

铅锌作为有色金属,在电气电子、机械制造、航空军事、冶金化工等领域被广泛应用,而在铅锌矿冶炼生产过程中,排放出的废水含有大量的金属铊,这种剧毒的金属元素一旦进入生物体内,极易诱发癌症或者畸变,而且也会对人体的神经中枢系统造成持续性伤害。因此,近年来,铅锌矿冶炼行业不断对含铊废水的治理技术进行改进和优化,旨在最大限度地减少冶炼废水中的金属铊含量。结合实际应用案例,对含铊废水的治理技术以及治理成效进行全面论述。

As a non-ferrous metal,lead and zinc are widely used in the fields of electrical and electronic,mechanical manufacturing,aviation and military,metallurgy and chemical industry.In the smelting process of lead and zinc mine,the waste water discharged contains a large amount of metal thallium.Once this toxic metal element enters the organism,it is very easy to induce cancer or distortion,and it will also cause sustained damage to the human central nervous system Sexual harm.Therefore,in recent years,the lead-zinc smelting industry continues to improve and optimize the treatment technology of thallium containing wastewater,in order to minimize the content of thallium in smelting wastewater.In this paper,combined with practical application cases,the treatment technology and treatment effect of thallium containing wastewater are comprehensively discussed.
