Agricultural vegetable wastewater treatment system and treatment method

The agricultural vegetable wastewater treatment system comprises a first box body, a top cover, a driving motor, a water inlet pipe and a feeding pipe, the top of the first box body is provided with the top cover, the upper surface of the top cover is fixedly provided with the driving motor through a bolt, and the top cover is further provided with the water inlet pipe and the feeding pipe; and the rotating shaft is connected with the output end of the driving motor. According to the agricultural vegetable wastewater treatment system and treatment method, when a first magnet rotates and corresponds to a second magnet, mutual exclusion force can be generated, so that the second magnet and a knocking block are pushed to move, and the knocking block knocks and vibrates the inner wall of a first inner barrel body; therefore, impurities such as vegetable leaves adsorbed on the inner wall of the first inner barrel body are vibrated to fall off, when the first magnet rotates to be staggered with the second magnet, t
