Equipment for treating printing and dyeing wastewater through combination of reverse osmosis and hydroxyl oxidation and treatment method thereof

The invention discloses equipment for treating printing and dyeing wastewater through combination of reverse osmosis and hydroxyl oxidation and a treatment method thereof.The equipment comprises a treatment pond, an overturning assembly is arranged on the surface of the treatment pond, a uniform mixing assembly is arranged on the surface of the overturning assembly, and an anti-blocking assembly is arranged on the surface of the uniform mixing assembly; through the arrangement of the uniform mixing assembly and the anti-blocking assembly, in the hydroxyl oxidation treatment process, hydroxyl oxidation mixed gas and liquid are sprayed out from the bottom of a nozzle, and the nozzle moves back and forth at the bottom of a treatment pond, so that wastewater in the treatment pond is in uniform contact with wastewater, and the wastewater and the hydroxyl oxidation mixed gas and liquid are rapidly mixed; by means of the arranged overturning assembly, after hydroxyl oxidation mixed gas and liquid are output, in orde
