What are the physicochemical methods for treating waste water containing flotation reagents?
(1) Adsorption method
The adsorbent is made of activated carbon, slag, kaolin, and the like. For example, when kaolin 20g/L, the removal rate of butyl xanthate is 89% and the turpentine removal rate is 80%.
(2) Coagulation method
Flotation reagent to the waste water containing the coagulant dosing, wastewater flotation agent and the metal is able to aggregate and precipitate.
(3) Ion exchange method
The yellow drug-containing wastewater is precipitated, filtered, neutralized, and passed through an AB-17 resin or a cationic resin to remove the xanthate from the wastewater.
