[0041] Working principle: When the present invention is used, sewage enters the treatment box 401 through the water inlet 3, and the sewage falls through the first grid plate 402 and the second grid plate 403, thereby entering the pump station body 1, and the solid impurities of different sizes in the sewage stay on the first grid plate 402 and the second grid plate 403 respectively. At this time, the electric push rod 404 is controlled to operate. The internal technology of the electric push rod 404 is the existing technology. After the electric push rod 404 operates, it drives the connecting plate 405 at the output end to move. When the connecting plate 405 moves, it drives the vertical knives 406 and the horizontal knives 407 at the upper and lower ends to move to the left. The vertical knives 406 and the horizontal knives 407 with large spacing above break the large-volume impurities on the first grid plate 402 for multiple times until the impurities are broken and dispersed and can fall. The impurities are crushed to the second grid plate 403, while the vertical blades 406 and horizontal blades 407 with small spacing below perform secondary crushing on the impurities, so that the impurities are crushed again and dispersed and fall into the pump station body 1 to mix with the sewage. In this way, the fixed impurities are continuously reduced in volume, so that when the submersible pump 5 is transported, there will be no blockage. When the vertical blades 406 and horizontal blades 407 at the top move, if the impurities are completely crushed, the pressure sensor 408 at the top of the horizontal blade 407 will contact the inner wall of the sealing plate 409, and the pressure data generated by the contact will be recorded and analyzed. When the pressure data is zero, it means that the impurities cannot be crushed, and the pressure sensor 408 at the top of the horizontal blade 407 cannot fit with the sealing plate 409. At this time, the pump station management platform has detected the pressure of zero for many times. In this case, it is necessary to carry out maintenance and deal with impurities. At this time, the three submersible pumps 5 are running to discharge the sewage in the pump station body 1 through the pressure water pipe 6 and the outlet 7. During the sewage treatment process, the deodorization system 15 absorbs and purifies the odor inside the pump station body 1 and discharges it through the ventilation pipe 16. At the same time, the pumping pump 1204 on the pumping pipe 1203 at the bottom of the water storage tank 1201 is controlled to operate, and the sewage is extracted and stored in the water storage tank 1201, and the first heater 1202 is controlled to operate to heat the pumped water. After the sewage is discharged, the booster valve 1206 on the outlet pipe 1205 is controlled to operate, so that the hot water in the water storage tank 1201 is pressurized and enters the movable pipe 1207 and is sprayed out through multiple nozzles 1208. At this time, the motor 1 is controlled 209 is running, the internal technology of the motor 1209 is the existing technology. After the motor 1209 is running, it drives the movable tube 1207 at the output end to rotate, so that when the movable tube 1207 rotates, the multiple nozzles 1208 at the bottom thereof can continuously rotate to both sides, so that the entire area at the bottom of the pump station body 1 can be scrubbed, so that the precipitated impurities are mixed with the sewage and then transported out by the submersible pump 5 to achieve the cleaning purpose, and then the second heater 1305 inside the high-temperature box 1301 is controlled to run, and the external water enters the high-temperature box 1301 through the water inlet pipe 1303. After the water is heated, high-temperature steam is generated, and then the outlet valve 1307 on the delivery pipe 1306 is opened, so that the high-temperature steam can enter the steam pipe 1308 through the delivery pipe 1306.And enter the interior of the pump station body 1 through multiple jet holes 1309, high-temperature steam continuously enters, and the interior of the pump station body 1 continues to be at high temperature and high pressure, thereby eliminating bacteria and the like that breed inside the pump station body 1, so that the pump station body 1 can maintain a relatively clean environment after cleaning and sterilization, so as to ensure the smooth treatment of sewage.
