The invention relates to a method for treating butyl xanthate in tailings pond wastewater, comprising the following steps: adding catalyst MgFe 2 O 4 -ZnO and sodium chlorate to the butyl xanthate-containing tailing pond wastewater, and keeping it away from light Mixing under the condition is not less than 30min, and the mass ratio of butyl xanthate, catalyst MgFe 2 O 4 ‑ZnO and sodium chlorate contained in the waste water is 1:(30～100):(5～10); Exposure to light conditions to degrade. The method can basically remove butyl xanthate in wastewater, and has the advantages of mild reaction conditions, high treatment efficiency and no secondary pollution. The photocatalyst is easy to be separated from the reaction system during application, has high reuse rate, and has good application prospects. |
