The filter plate 4 can intercept larger particles of impurities in the sewage to prevent the large particles of impurities from entering the box body 1, so that the sewage flows into the box body 1. When it is necessary to clean the larger particles of impurities on the filter plate 4, the sealing door 6 is opened by the handle, so that the positioning rod 15 is separated from the positioning hole 13 through the rectangular plate by pulling the positioning rod 15, so as to pull the positioning rod 15.

[0029] like Figure 2-9As shown, a plurality of hollow rotating shafts 23 are rotatably installed at the bottom of the box body 1, an aeration plate 24 is fixedly installed on the top of the hollow rotating shaft 23, the hollow rotating shafts 23 all penetrate and extend to the outer wall of the box body 1, and a second rotating rod 25 is fixedly installed at one end of the plurality of hollow rotating shafts 23 that penetrate and extend to the box body 1, and the other ends of the plurality of second rotating rods 25 are rotatably connected to the same U-shaped frame 26, and a gear 27 is fixedly installed on the outer wall of the second rotating rod 25, and the three gears 27 are meshed and connected by a toothed belt 28, a bottom plate 29 is fixedly installed on one side of the bottom end of the outer wall of the box body 1, and a second motor 30 is fixedly installed on the side of the bottom plate 29 away from the gear 27, and the output end of the second motor 30 is connected to one of the second rotating rods The moving rod 25 is fixedly connected, and the multiple hollow rotating shafts 23 penetrate and extend to the other end of the outer wall of the box body 1 and are rotatably connected with a water inlet pipe 31. The water inlet pipe 31 is fixed on one side of the box body 1 through a fixing plate, and a sealing ring is provided between the water inlet pipe 31 and the hollow rotating shaft 23. The top of the outer wall of the water inlet pipe 31 is fixedly connected with an air inlet pipe 32, and a third solenoid valve is provided inside the air inlet pipe 32. A fourth solenoid valve is provided inside the end of the water inlet pipe 31 close to the air inlet pipe 32.

A water level scale is provided on one side of the bottom of the outer wall of the box body 1, and the water level scale is used to check the height of the sewage in the box body 1 and the progress of sewage treatment.

[0030] By closing the fourth solenoid valve, the air inlet pipe 32 is connected to the external air pipe, thereby opening the third solenoid valve, so that the gas flows into the high-pressure water pipe through the air inlet pipe 32, and enters the interior of the hollow shaft 23 through the high-pressure water inlet pipe, so that the gas enters the interior of the aeration plate 24 through the hollow shaft 23, and the gas is discharged into the box body 1 through the aeration plate 24, thereby enhancing the aeration effect of the sewage in the box body 1, and the second motor 30 is started to rotate, so that the output end of the second motor 30 drives the second rotating rod 25 to rotate, thereby driving one of the three gears 27 to rotate, so that the toothed belt 28 meshing with the gear 27 rotates the other two gears 27 synchronously, through The hollow shaft 23 fixedly installed at one end of the second rotating rod 25 rotates, thereby driving the aeration plate 24 fixedly installed on the top of the hollow shaft 23 in the box body 1 to rotate, so that the aeration plate 24 evenly aerates the sewage in the box body 1. Through the rotation of the stirring blades 22 and the aeration plate 24, the mixing uniformity of the liquid medicine and the sewage is effectively improved while the sewage is better aerated, thereby accelerating the sewage treatment speed. When the hollow shaft 23 needs to be flushed, the high-pressure water inlet pipe is connected to the external water pipe, and the fourth solenoid valve is opened, so that clean water enters the hollow shaft 23 and the aeration plate 24 through the high-pressure water pipe, and is then discharged through the aeration plate 24, which can play a flushing role and avoid sediment inside the pipeline.

[0031] Working principle: The sewage is introduced into the box 1 through the water inlet hole 2 for aeration treatment, so that the sewage is gathered through the guide plate 3 and then flows to the filter plate 4 for filtration. The filter plate 4 can intercept the larger particles of impurities in the sewage to prevent the large particles of impurities from entering the box 1. After the sewage flows into the box 1, the second solenoid valve is activated to make the liquid medicine in the medicine box 16 flow into the medicine outlet pipe 18, and then flow into the box 1 in turn through the medicine outlet branch pipe 19. When the second solenoid valve is closed, the first motor 20 is started to rotate, thereby driving the first rotating rod 21 to rotate, so that the stirring blade 22 is rotated, so that the sewage and the liquid medicine in the box 1 are stirred and mixed, thereby increasing the contact area between the sewage and the treatment liquid medicine. Improve the efficiency of the reaction between the treatment liquid and the sewage, and improve the treatment effect of the sewage treatment. After stirring and mixing, close the fourth solenoid valve, so that the air inlet pipe 32 is connected to the external air pipe, so as to open the third solenoid valve, so that the gas flows into the high-pressure water pipe through the air inlet pipe 32, and enters the interior of the hollow shaft 23 through the high-pressure water inlet pipe, so that the gas enters the interior of the aeration plate 24 through the hollow shaft 23, so that the gas is discharged into the box body 1 through the aeration plate 24, so as to enhance the aeration effect of the sewage in the box body 1, and start the second motor 30 to rotate, so that the output end of the second motor 30 drives the second rotating rod 25 to rotate, thereby driving one of the three gears 27 to rotate, so that The toothed belt 28 meshing with the gear 27 rotates the other two gears 27 synchronously, and rotates through the hollow shaft 23, thereby driving the aeration plate 24 to rotate, so that the aeration plate 24 evenly aerates the sewage in the box body 1. Through the rotation of the stirring blade 22 and the aeration plate 24, the mixing uniformity of the liquid medicine and the sewage is effectively improved while the sewage is better aerated, thereby accelerating the sewage treatment speed. After the aeration treatment, the first motor 20 and the second motor 30 are turned off, and the third solenoid valve is turned off, thereby opening the fifth solenoid valve, so that the aerated sewage is discharged through the drain pipe 33. After discharge, when it is necessary to clean the larger particles of impurities on the filter plate 4, the sealing door 6 is opened by the handle, so that By pulling the positioning rod 15, the positioning rod 15 is separated from the positioning hole 13 through the rectangular plate, thereby pulling the handle, so that the handle drives the scraper 11 to scrape the surface of the filter plate 4 through the fixing rod 12, so that the scraper 11 can better scrape the larger particle impurities on the filter plate 4 into the discharge box 8 through the through groove 5 through the slider 10, thereby repeatedly scraping to prevent the particle impurities from blocking the filter plate 4 due to long-term use, thereby affecting the sewage from entering the box body 1, thereby pulling out the discharge box 8, cleaning the particle impurities in the discharge box 8, and facilitating the next use, thereby closing the sealing door 6, and facilitating the aeration treatment of the next sewage. When it is necessary to flush the hollow shaft 23, the fourth solenoid valve is opened by connecting the high-pressure water pipe with the external water pipe.Thus, clean water enters the hollow shaft 23 and the aeration plate 24 through the high-pressure water pipe, and then is discharged through the aeration plate 24, which can play a flushing role and avoid sediment inside the pipe.
