| titleOfInvention | Method for degrading residual agent in beneficiation wastewater by photocatalytic semiconductor sulfide ore based on iron-oxidizing bacteria |
| abstract | The invention discloses a method for degrading residual agent in beneficiation wastewater by photocatalytic semiconductor sulfide ore based on iron-oxidizing bacteria. The semiconductor sulfide ore can generate photoproduction electrons and photoproduction holes through catalysis of visible light irradiation, and residual agents in the mineral processing wastewater can be oxidized and decomposed by the photoproduction holes, so that the aim of reducing the COD value of the wastewater is fulfilled. The iron-oxidizing bacteria can remove Fe in sulfide ore 2+ Oxidation to Fe 3+ Photo-generated electrons and Fe 3+ Acting to reduce it to Fe 2+ Therefore, the composition of photoproduction electrons and photoproduction holes is reduced, the efficiency of the photoproduction hole oxidative decomposition beneficiation reagent is increased, the COD value can be obviously reduced, and the highest reduction rate can reach 98.2%. The method of the invention has simple required instruments and equipment, can increase the reutilization of the tailings and provides a new way for treating the residual medicament in the beneficiation wastewater. |
