[0029] The working principle of the hospital sewage treatment device provided by the utility model is as follows:

[0030] When in use, firstly, the water inlet 24 is connected to a water pump so that the water pump guides the medical sewage into the interior of the bottom end of the tank body 21 through the water inlet 24, and the sewage outlet 22 is blocked to prevent sewage leakage, so that the water level of the sewage slowly rises upward from the bottom end of the tank body 21, and first the water level rises to the filter grid 25, and the filter grid 25 first filters the rising sewage to filter out impurities mixed in the sewage, and the impurities in the filtered sewage will be greatly reduced. At this time, by connecting the motor 31 to an external power supply, the driving rod 32 drives the cleaning fixing frame 61 and the telescopic rod 51 fixed at the bottom to rotate synchronously, and then the fixing frame 61 drives the cleaning brush 62 to brush the bottom surface of the filter grid 25, so that the cleaning brush 62 brushes down the filtered impurities to prevent impurities from clogging the filter grid 25, and at the same time, the telescopic frame drives the scraping brush 52 to slide on the inner wall of the tank body 21, so that The scraping brush 52 cleans the inner wall of the tank body 21 so that the filtered impurities will not stick to the inner wall of the tank body 21. As the sewage water level rises, one end of the air pipe 42 is connected to the air pump through the connecting pipe 41. As the sewage overflows the air pipe 42, the air pump will compress air into the interior of the air pipe 42, so that the compressed air inside is ejected through the aeration head 43, thereby aerating the sewage. At the same time, the driving rod 32 also drives the stirring blade 33 to rotate, thereby causing the stirring blade 33 to stir the sewage. When the sewage overflows the biological filler 7, the air ejected from the aeration head 43 will accelerate the oxidation of the biological filler 7, thereby causing the biological filler 7 to quickly oxidize and degrade harmful substances in the sewage, and then the purified water is discharged from the drain port 23. This device has the advantages of being easy to clean impurities that are easily adhered to the inner wall of the device and the filter screen, using aeration to accelerate the oxidation of the filter material, quickly oxidizing and degrading, and accelerating the purification speed.

[0031] Compared with the related art, the hospital sewage treatment device provided by the utility model has the following beneficial effects:

[0032] The utility model provides a hospital sewage treatment device, which can first be connected to a water pump through the water inlet 24 provided at the bottom end of the containing structure 2 to make it run, and can inject medical sewage from the bottom end of the containing structure 2 to make the sewage slowly rise inside the containing structure 2, and the filter grille 25 fixed inside the bottom end of the containing structure 2 will initially filter impurities in the sewage, and by connecting the stirring structure 3 to an external power supply, the stirring structure 3 is driven to rotate inside the containing structure 2, which will first drive the scraping wall structure 5 and the cleaning structure 6 fixed at the bottom segment to rotate, and the cleaning structure 6 will clean the bottom surface of the filter grille 25, so that the filtered impurities cannot be blocked, so that the sewage can flow continuously, and the scraping wall structure 5 can scrape off the impurities adsorbed on the inner side wall of the bottom end of the containing structure 2. After use, the filtered impurities can be discharged through the sewage outlet 22 to avoid blockage caused by excessive impurities. When the sewage water level reaches a certain depth, the air pump compresses air into the aeration structure 4, so that the air is sprayed into the inside of the containing structure 2 through the aeration structure 4, so that the aeration structure 4 increases the oxygen content inside the containing structure 2, thereby promoting the rapid oxidation of the biological filler 7 layer, and quickly oxidizing and degrading harmful substances in the sewage, and then the purified water is discharged from the drain outlet 23. This device has the advantages of being easy to clean impurities that are easily adhered to the inner wall of the device and the filter screen, using aeration to accelerate the oxidation of filter materials, and quickly oxidizing and degrading, thereby accelerating the purification speed.
