[0002] The decentralized sewage treatment device is mainly used for treating sewage, also known as the biofilm technology. It exists in the form of a biofilm, greatly increasing the microbial concentration per unit reactor volume, thus effectively improving the volumetric load of the reactor, enhancing the overall anti-shock load capacity and treatment effect of the system, and saving floor space. Currently, when the decentralized sewage treatment device is in operation, the sewage is first filtered through a filter tank at the position of the water inlet box. However, after a long time of filtration, a large amount of pollutants will adhere to the bottom, which will reduce the subsequent filtration effect. Content of the Utility Model

One side of the bottom of the treatment tank is fixedly installed with a water outlet pipe. A cleaning mechanism is arranged inside the water inlet box, and the cleaning mechanism includes a cleaning roller, a fixed rod, a moving block and a lead screw. One side of the water inlet box is rotatably connected with a lead screw that penetrates and extends into the water inlet box. The outer circle of the lead screw located inside the water inlet box is threadedly connected with a moving block. One side of the moving block is fixedly installed with a fixed rod. One end of the fixed rod away from the moving block is rotatably connected with a cleaning roller, and the cleaning roller is connected to the bottom of the filter tank.

[0005] Preferably, a motor is fixedly installed on one side of the water inlet box, and a rotating shaft is fixedly installed on the output shaft of the motor.

[0019] In order to more clearly explain the overall concept of the present invention, the following will be described in detail by way of examples in conjunction with the drawings of the specification.

[0020] As Figures 1 to 4 shown, the embodiment of the present invention provides a multi-gear decentralized sewage treatment device, including a treatment tank 1, a water inlet box 2 is provided on one side of the treatment tank 1, a filter tank 3 is provided on the top of the water inlet box 2, a plug plate 10 is provided at the bottom of the water inlet box 2, and a water outlet pipe 12 is fixedly installed at the bottom of one side of the treatment tank 1.

[0021] The interior of the water inlet box 2 is provided with a cleaning mechanism, and the cleaning mechanism includes a cleaning roller 4, a fixed rod 5, a moving block 6 and a lead screw 7. One side of the water inlet box 2 is rotatably connected to a lead screw 7 that penetrates and extends into the water inlet box 2. The outer circumference of the lead screw 7 located inside the water inlet box 2 is threadedly connected to a moving block 6. One side of the moving block 6 is fixedly installed with a fixed rod 5. One end of the fixed rod 5 away from the moving block 6 is rotatably connected to a cleaning roller 4, and the cleaning roller 4 is connected to the bottom of the filter tank 3.

[0022] One side of the water inlet box 2 is fixedly installed with a motor 9. The output shaft of the motor 9 is fixedly installed with a rotating shaft 13. The motor 9 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the pulley group 8 to rotate.

[0023] One end of the rotating shaft 13 is fixedly installed with a pulley group 8, and the other end of the pulley group 8 is fixedly connected to the lead screw 7. The pulley group 8 is used for driving connection between the rotating shaft 13 and the lead screw 7.

[0024] One side of the inner wall of the water inlet box 2 is fixedly installed with a guide rod 11. The guide rod 11 is inserted through the moving block 6. The guide rod 11 is used to limit the moving moving block 6 to prevent it from shifting during movement.

[0025] The interior of the treatment tank 1 is respectively provided with a sedimentation chamber 14, an anoxic chamber 15, an aerobic chamber 16 and a disinfection chamber 17. The sewage is sedimented by the sedimentation chamber 14, and the anoxic treatment is carried out on the sewage in the anoxic chamber 15 to kill the aerobic organic matter therein. The aerobic treatment is carried out on the sewage in the aerobic chamber 16, and the disinfection treatment is carried out on the sewage in the disinfection chamber 17.

[0026] The inner walls of the sedimentation chamber 14, the anoxic chamber 15, the aerobic chamber 16 and the disinfection chamber 17 are all installed with return pipes, and the other ends of the return pipes all penetrate into the next chamber. The return pipes are used for guiding flow between adjacent chambers.

[0027] In order to better illustrate the present utility model, the following specifically describes its working principle:

[0028] Pour the sewage into the filter tank 3. After filtration, it is transported into the sedimentation chamber 14, and then transported into the anoxic chamber 15 through a diversion pipe for anoxic treatment to kill the aerobic organic matter. The treated sewage is then treated by the aerobic chamber 16, and finally the treated sewage is transported into the disinfection chamber 17 through a diversion pipe for disinfection treatment. After treatment, it is discharged through the water outlet pipe 12. When the bottom of the filter tank 3 is blocked by pollutants in the long-term use, first remove the plug board 10, and then start the motor 9 to drive the rotating shaft 13 to rotate. The lead screw 7 will be driven to rotate through the pulley group 8, and the fixed rod 5 will be driven to move through the moving block 6, which will drive the cleaning roller 4 to roll back and forth at the bottom of the filter tank 3 to clean the adhered pollutants, facilitating better subsequent filtration treatment.
