[0018] A method for treating printing and dyeing wastewater by reverse osmosis combined with hydroxyl oxidation, using a device for treating printing and dyeing wastewater by reverse osmosis combined with hydroxyl oxidation, comprising the following steps:

[0019] S1. Start the high-pressure water gun to impact the printing and dyeing wastewater to the surface of the reverse osmosis membrane, and then the printing and dyeing wastewater is separated by reverse osmosis. By starting the water pump, the separated and infiltrated wastewater is pumped into the interior of the treatment tank;

[0020] S2, then start the flip assembly, first move the uniform mixing assembly and the anti-clogging assembly downward, so that the nozzle is separated from the lower surface of the sealing sleeve, and then rotate 180 degrees, and then the mixing assembly and the anti-clogging assembly slide downward, so that the mixing assembly and the anti-clogging assembly are at the bottom of the treatment tank;

[0021] S3, the hydroxyl oxidation gas-liquid mixture is transported to the interior of the uniform mixing component, and the hydroxyl oxidation gas-liquid mixture is uniformly mixed with the wastewater through the setting of the uniform mixing component, and the anti-clogging component is set during the fusion process to avoid the nozzle from being blocked;

[0022] S4. After the treatment is completed, slide the mixing component and the anti-clogging component upwards. When sliding to the middle, the mixing component and the anti-clogging component rotate 180 degrees counterclockwise, and the wastewater or impurities adhering to the inside of the mixing component are forcefully thrown out by centrifugal force, and the corrosive substances in the wastewater are removed from the surface of the pipe, and then the nozzle is sealed by the sealing sleeve.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Through the uniform mixing component and anti-clogging component, during the hydroxyl oxidation treatment, the hydroxyl oxidation mixed gas and liquid are sprayed out from the bottom of the nozzle, and the nozzle moves back and forth at the bottom of the treatment tank, so that the wastewater inside the treatment tank is evenly contacted with the wastewater, so that the wastewater and the hydroxyl oxidation mixed gas and liquid are quickly mixed. Since the hydroxyl oxidation mixed gas and liquid are sprayed, the gas and liquid will impact and drive the wastewater at the bottom to drive the internal wastewater to surge, thereby replacing the traditional operation method of mixing by stirring, and ensuring the working environment of the staff.

[0025] 2. Through the anti-clogging component, when the hydroxyl oxidation mixed gas and liquid are sprayed out from the bottom of the nozzle, impurities in the wastewater may cause the nozzle to be blocked. When the nozzle is swinging, the brush plate at the bottom will repeatedly rub against the bottom of the nozzle, rubbing the bottom surface of the nozzle to clean the impurities that may be blocked on the surface of the nozzle, thereby ensuring the high fluidity of the nozzle and improving the treatment efficiency of the combined hydroxyl oxidation of the device;

[0026] 3. Through the setting of the flip component, when the hydroxyl oxidation mixed gas and liquid are output, in order to avoid the components being inside the wastewater for a long time, it is necessary to separate the internal components from the wastewater. When the V-shaped structure of the moving path groove is turned 180 degrees, the internal wastewater is thrown out through the centrifugal force during rotation, which prevents the wastewater or impurities from adhering to the surface of the device, avoids the erosion of the components by the wastewater, and improves the service life of the components.

[0027] 4. By setting up a flip assembly and a sealing sleeve, the pipe can be flipped 180 degrees during the upward sliding process, so that the bottom nozzle is at the top. After the flip is completed, it continues to slide upward, and the sealing sleeve is used to seal and protect the nozzle, thereby preventing the nozzle from being contaminated by the outside world. At the same time, it prevents external impurities from entering the interior of the pipe through the nozzle, thereby reducing the life of the pipe. BRIEF DESCRIPTION OF THE DRAWINGS
