Experimental Study on key technologies for risk prevention and control of thallium pollution in A lead-zinc mine wastewater

Abstract

In order to reduce the environmental risk of thallium pollution by enterprises and determine key technologies for thallium pollution prevention and control, the researcher conducted a deep exploration experiment on thallium removal in the inflow water of a certain lead-zinc mine. The experimental results showed that both sulfide precipitation method and catalytic oxidation & resin adsorption can achieve good thallium removal effect. Based on the actual characteristics of the lead-zinc industry, The author recommends a thallium pollution risk control technology scheme that combines terminal sulfide precipitation and source resin adsorption for thallium removal.
