2) Purification: Add ammonium persulfate to the final immersion solution for one-time oxidation and iron removal, and add activated carbon to adsorb arsenic and iron co-precipitation to achieve the purpose of removing arsenic. Add the polyacrylamide coagulant to separate and filter before separation. The sulfide solution is added to the solution to remove sulfur, and the separated filtrate obtained by the separation is replaced with zinc powder to remove the remaining impurities to obtain a zinc sulfate ammonia complex liquid, which is used in the next step;
