The cleaning cone plate 33 is an elastic member and the bottom tip can be inserted into the gap of the grille 6. As the cleaning frame 17 descends, the cleaning cone plate 33 is continuously inserted into the gap of the grille 6 and then leaves to take away the blockages accumulated on the grille 6. The cleaning frame 17 moves to the bottom and then rises. Due to the resistance of the sewage and the shape of the cleaning cone plate 33, the blockages scraped off by the cleaning cone plate 33 will automatically fall off and gather at the bottom of the pretreatment tank, thereby completing the automatic cleaning of the grille 6 while removing the floating dirt on the sewage surface;

[0028] The coagulant supply mechanism is arranged on the cleaning frame 17. As the cleaning frame 17 moves up and down, the coagulant supply mechanism sprays the coagulant into the sewage in the coagulation tank. Spraying the coagulant to water layers of different heights helps the coagulant and sewage to be fully mixed, thereby reducing the reaction dead zone and short circuit phenomenon.
