[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a domestic sewage treatment device with a sterilization function comprises a filtering mechanism 1, a sterilization mechanism 2 is installed at the front of the filtering mechanism 1, an anaerobic tank 3 is installed at the front of the sterilization mechanism 2, an aeration tank 4 is installed at the front of the anaerobic tank 3, a sedimentation tank 5 is installed at the front of the aeration tank 4, a disinfection tank 6 is installed at the front of the sedimentation tank 5, the filtering mechanism 1 comprises a grille tank 7, a chain belt 8 is movably installed through the rear end of the grille tank 7 and located inside, a motor 10 is installed at one end of the rotating shaft of the rear part of the chain belt 8, an inclined plate 9 is installed at the rear part of the grille tank 7 and below the chain belt 8, a disinfection pipe 11 is installed inside the grille tank 7 near the top, a plurality of nozzles 12 are installed on the periphery of the disinfection pipe 11, a water inlet 13 is opened through the top of the grille tank 7, a collecting box 14 is installed at the rear of the grille tank 7, a discharge port 15 is opened through the rear of the collecting box 14, and a sealing plate 16 is movably installed inside the discharge port 15.

[0023] In this embodiment, the chain belt 8 is located inside the grid pool 7 and is inclined. The surface of the chain belt 8 is arranged in a penetrating mesh. The motor 10 drives the chain belt 8 to rotate to filter large debris in the domestic sewage.

[0024] In this embodiment, the spray direction of the nozzle 12 is downward, and a plurality of nozzles 12 are arranged equidistantly. By connecting the disinfectant to the disinfection tube 11 and spraying it through the nozzle 12 under high pressure, the filtered debris can be disinfected, and at the same time, the disinfectant water can flow into the grid pool 7 to disinfect the sewage.

[0025] In this embodiment, the collecting box 14 is located directly below the rear end of the chain belt 8 , and the sealing plate 16 is located inside the discharge port 15 and is movably rotatable. The filtered debris is transmitted to the rear end of the chain belt 8 and collected by the collecting box 14 .

[0026] In this embodiment, the sterilization mechanism 2 includes a baffle 17, which is installed at the front of the grille pool 7. A flow groove 18 is opened through the front and rear parts of the baffle 17 near the bottom end. A grille plate 19 is installed inside the flow groove 18. A sterilization pool 20 is arranged at the front of the baffle 17. A drainage groove 21 is opened through the front part of the sterilization pool 20 near the top. Two ultraviolet sterilization lamps 22 are installed at the bottom of the sterilization pool 20. The filtered and disinfected sewage flows into the sterilization pool 20 through the flow groove 18 under the action of water pressure and is sterilized by the ultraviolet sterilization lamp 22.

[0027] In this embodiment, the sterilization tank 20 is interconnected with the grid tank 7 through the circulation groove 18, and the main surface of the grid plate 19 is arranged in a grid shape. The grid plate 19 allows the impurities that are not completely filtered out of the sewage to be further filtered, thereby reducing the entry of impurities and sludge.

[0028] In this embodiment, the sterilization tank 20 is interconnected with the anaerobic tank 3 through the drainage trough 21, and the irradiation direction of the two ultraviolet sterilization lamps 22 is facing directly downward. The sewage is located in the sterilization tank 20 and is continuously and sequentially irradiated and sterilized by the ultraviolet sterilization lamps 22. Under the action of water pressure, it passes through the drainage trough 21 and enters the anaerobic tank 3 for the next step of processing.

[0029] It should be noted that the utility model is a domestic sewage treatment device with a sterilization function. When in use, domestic sewage first enters the grille pool 7 through the water inlet 13. Since large debris such as leaves and domestic garbage remain in the sewage, when filtering, the motor 10 is started to rotate the chain belt 8, and the debris is filtered and transported through the chain belt 8. At the same time, the disinfectant is connected to the disinfection pipe 11 and sprayed onto the surface of the debris in sequence through the nozzle 12 for disinfection. At the same time, part of the disinfectant flows into the grille pool 7 to pre-disinfect the sewage. The debris passes through the chain belt 8. It is transported to the rear end and falls into the collection box 14 for collection. It is opened through the sealing plate 16 for regular cleaning. Under the action of water pressure, the pre-sterilized sewage flows into the sterilization tank 20 through the circulation groove 18. At the same time, the impurities that are not completely filtered are further filtered through the grid plate 19. During the upward flow of the sewage in the sterilization tank 20, it is continuously sterilized by the irradiation of two ultraviolet sterilization lamps 22. Since the drainage groove 21 is lower than the top of the grid tank 7, the sterilized sewage flows into the anaerobic tank 3 through the drainage groove 21 for the next step of treatment.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
