[0034] Specifically, when the local surface water pollution treatment and purification equipment is working: the water pump 7 is started to pump the external surface water to be treated and purified into the inner cavity of the box body 1 through the water pumping pipe 8 and the water outlet pipe 9. When the surface water passes through the filter screen 2, the larger impurities will be filtered and blocked by the filter screen 2, and the filtered water will fall on the driving blade 302 just below. Driven by the water flow, the first rotating shaft 301 rotates clockwise, thereby driving the driving gear 303 to rotate clockwise. As the driving gear 303 rotates clockwise, the first driven gear 407 meshing with it rotates counterclockwise, and the traction rope 405 on the rope winding roller 406 is wound, thereby driving the telescopic rod 402 to extend, the telescopic spring 404 is stretched, and the pushing plate 403 moves leftward in the sliding groove 408. Since the bottom of the pushing plate 403 is in contact with the surface of the filter screen 2, the solid impurities on the filter screen 2 are scraped off during the movement and passed through the pushing port 4 01 is pushed into the impurity storage box 11 on the left, and when the driving gear 303 rotates to the toothless part and contacts the first driven gear 407, the driving gear 303 can no longer drive the first driven gear 407 to rotate counterclockwise, and the first driven gear 407 loses its power source. At this time, the telescopic spring 404 rebounds, and the telescopic rod 402 contracts, driving the pushing plate 403 to move rightward along the sliding groove 408. At the same time, the traction rope 405 on the rope roller 406 is unwound. Since the bottom of the pushing plate 403 is in contact with the surface of the filter screen 2, the solid impurities on the filter screen 2 can be scraped off during the movement and pushed into the impurity storage box 11 on the right through the pushing port 401. As the surface water is continuously drawn in, the impurities are continuously filtered. At the same time, the impurities on the filter screen 2 are also continuously cleaned into the impurity storage box 11, avoiding the blockage of the filter screen 2, greatly improving the efficiency of surface water treatment and purification; As the driving gear 303 rotates clockwise, the second driven gear 5043 meshing therewith is driven to rotate counterclockwise, and then the third rotating shaft 5042 drives the connecting rod 5044 and the fan ring 5045 to rotate counterclockwise. Due to the notch setting of the fan ring 5045, the chemical reagent in the storage box 5041 intermittently flows into the interior of the box body 1 through the inlet hole 5046; After being filtered by the filter screen 2, the surface water falls to the bottom of the box 1. As the first rotating shaft 301 rotates clockwise under the drive of the water flow, the second bevel gear 10 rotates clockwise, and then drives the first bevel gear 503 meshing therewith to rotate counterclockwise, thereby driving the second rotating shaft 501 and the stirring blade 502 to rotate counterclockwise. With the intermittent input of chemical reagents, the chemical reagents are quickly dissolved in the surface water, fully reacted and precipitated, and the sediment therein is removed; The surface water after filtration and coagulation treatment enters the biochemical treatment chamber 13, where organic pollutants are degraded by microorganisms, and heavy metals and difficult-to-degrade organic matter are removed through chemical reactions. Finally, the treated and purified surface water is discharged through the outlet 14. This equipment relies on the gravity impact of surface water to generate power, does not require electricity support, and is energy-saving and environmentally friendly.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
