Beneficial effects of the present invention:

1. The present invention can perform primary filtration treatment on large impurity particles in wastewater through the primary filter screen, reduce the load of subsequent treatment, and protect the normal operation of the equipment. Then, by adding an oxidant to the wastewater, the organic waste in the wastewater is effectively degraded, and the organic waste is converted into inorganic products or substances that are easier to treat, thereby reducing the concentration of organic matter in the wastewater, reducing pollution to the environment, and making the wastewater easier to subsequently treat or discharge. Then, by arranging three groups of activated carbon filter screens in the inner cavity of the storage chamber, it is convenient to divide the inner cavity of the storage chamber into three cavities, so that the wastewater entering the storage chamber can be filtered step by step for multiple times, which can gradually purify the wastewater, improve the wastewater treatment efficiency, and ensure that the discharged water quality meets environmental protection standards.

2. The present invention can automatically clean the large impurity particles filtered above the primary filter screen plate through a reciprocating cleaning plate, and store them in an impurity collection bin, so that the primary filter screen plate can be smoother when treating wastewater, and can better filter out impurities and particles in the wastewater, thereby improving the filtration efficiency of the primary filter screen plate. At the same time, manual cleaning will increase the maintenance cost of the equipment, and the equipment uses an automatic cleaning and collection mechanism, which can avoid the need for manual cleaning, thereby reducing the operation and maintenance cost of the equipment.

3. In the present invention, when the motor rotates to drive the cleaning plate to clean the primary filter screen plate, the stirring blades on the three groups of rotating rods can rotate in the inner cavity of the treatment chamber, so that the oxidant and the wastewater can be fully mixed, thereby improving the oxidation efficiency, and the oxidant can more fully react chemically with the organic matter in the wastewater to achieve a better oxidation effect. At the same time, after the stirring blades rotate in the inner cavity of the treatment chamber, the oxidant can more fully react with the wastewater, and the reaction time is shortened, thereby improving the treatment efficiency.

4. In the present invention, when the stirring blades on the three groups of rotating rods rotate in the processing chamber, they can drive the impact rod to rise and fall intermittently, and then make the rubber seat impact and contact the surface of the discharge pipe, which can intermittently vibrate the discharge pipe, thereby promoting the oxidant in the discharge pipe to fall, and effectively avoiding the oxidant from being blocked in the discharge pipe.
