[0019] The present invention also discloses a usage method of a device for catalytic oxidation of high-concentration industrial wastewater by ozone synergistic persulfate. Using the above-mentioned device for catalytic oxidation of high-concentration industrial wastewater by ozone synergistic persulfate, it includes the following steps:

[0020] S1. The high-concentration industrial wastewater is discharged into the interior of the treatment tank through the water inlet pipe. Through the mutual cooperation of the spraying mechanism and the stirring mechanism, the ozone liquid and the persulfate solution in the storage tank are injected into the interior of the treatment tank through the three-way water pipe and the spray pipe. Through the setting of the stirring mechanism, the ozone, persulfate and high-concentration industrial wastewater are stirred and mixed to treat the high-concentration industrial wastewater;

[0021] S2. When treating the high-concentration industrial wastewater, start the bidirectional threaded rod to make the two sliding blocks and the stirring plate slide inside the treatment tank, so as to stir the liquid inside the treatment tank. At the same time, during the movement of the sliding blocks, the connecting rod is synchronously driven to move, so that the connecting rod drives the push rod to slide inside the hollow pipe, driving the push plate and the stirring mechanism to move, so that the stirring mechanism and the sliding blocks stir the liquid at the same time;

[0022] S3. When the treatment of the high-concentration industrial wastewater is completed, through the setting of the extraction water pump, the liquid inside the treatment tank is pumped out through the drain pipe, and the liquid is filtered through the filter plate, and finally the liquid is discharged through the discharge pipe;

[0023] S4. After the equipment for catalytic oxidation of high-concentration industrial wastewater by ozone in cooperation with persulfate is used up, start the sewage discharge motor to make the driving gear and the rotating rod rotate, so that the two baffle plates are inclined, so that the sludge inside the treatment tank is discharged. And the driving gear drives the linkage gear and the driven gear to rotate, driving the driving tooth plate to move, so that the limiting plate slides, and the sludge is discharged into the interior of the fixed bottom plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. By setting structures such as the equipment main body, stirring mechanism, filtering mechanism, spraying mechanism, sealing mechanism and discharging mechanism, start the stirring motor, and its output end drives the bidirectional threaded rod to rotate, so that the two sliding blocks slide inside the treatment tank, and at the same time drive the stirring plate to move synchronously, so as to stir the liquid inside the treatment tank through the sliding blocks and the stirring plate, so that the ozone, persulfate and high-concentration industrial wastewater are stirred, so that the mixture of the three is more uniform, and the equipment for catalytic oxidation of high-concentration industrial wastewater by ozone in cooperation with persulfate treats the high-concentration industrial wastewater more thoroughly, thereby improving the treatment effect of the equipment for catalytic oxidation of high-concentration industrial wastewater by ozone in cooperation with persulfate;

[0026] 2. By setting up structures such as the equipment main body, stirring mechanism, filtering mechanism, spraying mechanism, sealing mechanism, and discharging mechanism, when the equipment for ozone-assisted catalytic oxidation of high-concentration industrial wastewater is not in use, by rotating the bidirectional threaded rod, the sliding blocks are driven to move synchronously, thereby pushing the connecting rod to slide inside the treatment tank. This causes the connecting rod to drive the push rod to slide inside the hollow tube, and then the push plate moves, driving a number of sealing plates and sealing cleaning blocks to move synchronously. The sealing cleaning blocks are inserted into the inside of the spray head, thus providing sealing protection for the spray head. This prevents external debris from entering the spray head when it is not in use, which could cause blockage of the spray head, affecting the normal use of the spraying mechanism and the sealing mechanism, and thus affecting the use of the equipment for ozone-assisted catalytic oxidation of high-concentration industrial wastewater, reducing the usage efficiency of the equipment for ozone-assisted catalytic oxidation of high-concentration industrial wastewater.

[0027] 3. By setting up structures such as the equipment main body, stirring mechanism, filtering mechanism, spraying mechanism, sealing mechanism, and discharging mechanism, after the treatment of high-concentration industrial wastewater is completed, by starting the sewage discharge motor, the rotating rod rotates, which drives the baffle plate to rotate synchronously. This causes the sludge attached to the surface of the baffle plate to move on the baffle plate, and then the sludge is discharged from the inside of the treatment tank. At the same time, when the rotating rod rotates, it synchronously drives the driving gear to rotate, causing the linkage gear to drive the driven gear to rotate synchronously. The driven gear drives the driving tooth plate to move, and the limiting plate slides inside the fixed bottom plate. As a result, the limiting plate no longer limits the baffle plate and the treatment tank, allowing the sludge to flow into the inside of the fixed bottom plate, preventing the sludge from affecting the subsequent treatment of high-concentration industrial wastewater.

[0028] 4. By setting up structures such as the equipment main body, stirring mechanism, filtering mechanism, spraying mechanism, sealing mechanism, and discharging mechanism, when treating high-concentration industrial wastewater, by starting the spraying water pump, the three-way water pipe injects the ozone liquid and persulfate solution inside the storage tank into the inside of the spray pipe. Then, the ozone and persulfate mixed liquid is injected into the inside of the hollow plate. Through the mutual cooperation of the connecting pipe and the spray head, the mixed liquid is injected into the high-concentration industrial wastewater. With the setting of a number of spray heads, the spray heads spray different positions, avoiding the problem of incomplete mixing of high-concentration industrial wastewater and the mixed liquid caused by spraying only one position. At the same time, with the setting of the feed pipe, the staff can timely replenish ozone and persulfate. BRIEF DESCRIPTION OF THE DRAWINGS
