▎ 摘　　要

NOVELTY - Treating organic chromium complex wastewater and synchronously controlling production of hexavalent chromium, comprises (i) adding pH-adjusted trivalent chromium complex simulation solution or wastewater into a reaction vessel, where the trivalent chromium complex simulation solution or wastewater is composed of large amount of organic complexing agents, (ii) inserting prepared cathode and anode into the reaction solution, turning on the direct current power supply, and electrifying to generate hydrogen peroxide, (iii) continuously aerating a mixed gas of oxygen and ozone into the reaction vessel through a microporous aeration head, and carrying out aeration while hydraulic stirring to ensure that the reaction proceeds evenly, the reaction time is 30-120 minutes, and (iv) pickling the anode and cathode materials to recover the chromium electrodeposited/adsorbed on the anode and cathode materials. USE - The method is useful for treating organic chromium complex wastewater and synchronously controlling production of hexavalent chromium. ADVANTAGE - The method: utilizes electrogenerated hydrogen peroxide and ozone of carbon-based materials to efficiently crack the organic complex state chromium, and simultaneously controls the generation of hexavalent chromium through the multiple actions of electrogenerated hydrogen peroxide reduction, cathode electroreduction and anode electrosorption; greatly reduces the accumulation of chromium(VI); reduces the generation of chromium sludge hazardous waste; greatly reduces the treatment cost; and realizes the environmentally friendly treatment of organic chromium complex wastewater.
