The water inlet pipe 3 is located at the lower part of the sedimentation tank 2, so that the sewage is passed into the sedimentation tank 2 from the lower part. As the water inlet amount increases, the water flow moves upward, and the primary filter 4 will filter the sewage and block foreign matter. A large amount of foreign matter will settle downward due to gravity and will not accumulate on the primary filter 4, so as to avoid the sediment covering the primary filter 4 and affecting the sewage circulation. The water flowing through the primary filter 4 will flow out of the sedimentation tank 2 along the water guide pipe 6 under the action of the water pump 5 and enter the treatment tank 7 for subsequent treatment.

[0029] More specifically, after the sewage enters the treatment box 7, the medicine is added into the treatment box 7 from the feed pipe 8, and the stirring motor 9 is started, so that the stirring motor 9 controls the rotating frame 10 to rotate, and the rotating frame 10 drives the peripheral stirring shaft 11 to rotate around the center of the treatment box 7, and when the stirring shaft 11 moves, it will drive the transmission gear 13 to move, and the mobile transmission gear 13 cooperates with the transmission gear ring 14 to rotate the transmission gear 13, driving the stirring shaft 11 to rotate, and the stirring shaft 11 rotates around the center of the treatment box 7, generally rotating on its own, driving the stirring blade 12 to move, and complex stirring is performed through multiple groups of stirring blades, so that the sewage and the medicine are mixed more fully, and the reaction is fully carried out. The harmful substances are released from the water through the reaction of the medicine with the harmful particles in the sewage, and the sewage is treated.

[0035] Specifically, when the guide block 21 moves, it will contact the guide groove 20 through the cleaning blocks 22 at both ends. When moving, the foreign matter in the guide groove 20 is cleaned by the cleaning blocks 22 to prevent the foreign matter from remaining in the guide groove 20 and causing the movement of the cleaning scraper 19 to be blocked.

[0037] Specifically, when the treatment box 7 is working, the control valve 25 corresponding to the outlet pipe 23 is closed. After the treatment box 7 completes its work, the control valve 25 corresponding to the outlet pipe 23 is opened to allow the treated sewage to flow out of the outlet pipe 23 and fall into the purification box 15. The water passing through the purification box 15 is discharged through the drain pipe 24, and the working state is controlled by the corresponding control valve 25 on the drain pipe 24. In addition, the working state of the sedimentation box 2 is controlled by the control valve 25 on the water inlet pipe 3 and the water conduit 6.

[0038] Please refer to Figure 1 and Figure 2As a further implementation method of the sedimentation box: a discharge door 26 is provided at one end of the sedimentation box 2, and a hydraulic rod 27 is provided at the other end. A cleaning push plate 28 is provided in the sedimentation box 2, and the output end of the hydraulic rod 27 cooperates with the cleaning push plate 28, and the cleaning push plate 28 cooperates with the discharge door 26.

[0039] Specifically, when the sediment in the sedimentation box 2 is processed, the water supply to the sedimentation box 2 is stopped, and then the discharge door 26 is opened to discharge the residual water and sediment inside from the discharge door 26, and the cleaning push plate 28 is used to push the sediment out through the power of the hydraulic rod 27.

[0040] Please refer to Figure 1 and Figure 4 As a further implementation of the sedimentation box: the sedimentation box 2, the processing box 7 and the purification box 15 are all provided with an observation port 29, and a closed glass 30 is provided in the observation port 29.

[0041] Specifically, when the equipment is working, the working conditions in the sedimentation tank 2 , the treatment tank 7 and the purification tank 15 can be observed through the observation port 29 , and are kept stable by the closed glass 30 .

[0042] Please refer to Figure 4 As a further implementation of the purification box: a disinfection lamp 31 is provided in the purification box 15.

[0043] Specifically, when the purified water flows through the purification box 15, the water is irradiated by the disinfection lamp 31, thereby further improving the treatment quality of the water.

[0044] In summary: when using the device, sewage is introduced into the device, and the sewage is first precipitated. The corresponding control valve 25 on the water inlet pipe 3 is opened to allow the sewage to pass from the water inlet pipe 3 into the sedimentation tank 2. The water inlet pipe 3 is located at the lower part of the sedimentation tank 2, so that the sewage flows into the sedimentation tank 2 from the lower part. As the amount of water inflow increases, the liquid level rises, and the water moves upward, and the primary filter 4 will filter the sewage and block foreign matter. A large amount of foreign matter will settle downward due to gravity and will not accumulate on the primary filter 4, so as to prevent the sediment from covering the primary filter 4. The sewage circulation is affected, and the water flowing through the primary filter 4 will flow out of the sedimentation box 2 along the water guide pipe 6 under the action of the water pump 5, and enter the treatment box 7, so that the control valve 25 corresponding to the outlet pipe 23 is closed. After the sewage enters the treatment box 7, medicine is added to the treatment box 7 from the feed pipe 8, and the stirring motor 9 is started, so that the stirring motor 9 controls the rotating frame 10 to rotate, and the rotating frame 10 drives the peripheral stirring shaft 11 to rotate around the center of the treatment box 7, and when the stirring shaft 11 moves, it will drive the transmission gear 13 to move, and the moving transmission gear 13 will be driven to rotate. The moving gear 13 cooperates with the transmission gear ring 14 to rotate the transmission gear 13, driving the stirring shaft 11 to rotate. The stirring shaft 11 rotates around the center of the treatment box 7, generally rotating on its own, driving the stirring blade 12 to move. Complex stirring is performed by multiple groups of stirring blades to make the sewage and the medicine mixed more fully, so that the reaction is fully carried out. The harmful substances are released from the water through the reaction of the medicine with the harmful particles in the sewage, and the sewage is treated. After the treatment box 7 completes the work, the control valve 25 corresponding to the outlet pipe 23 is opened, so that the treated sewage flows out of the outlet pipe 23 and falls into the purification box 15. The sewage treated by the treatment box 7 is received by the purification box 15, filtered by the purification filter 16, and clean water is filtered out. Moreover, when the purified water flows through the purification box 15, the water is irradiated by the disinfection lamp 31 to further improve the treatment quality of the water. In addition, the purification box 15 is open in design, and when the next batch of sewage is treated, the pollutants on the purification filter 16 can be directly cleaned.

[0045] When the equipment is working, the working status of the sedimentation box 2, the treatment box 7 and the purification box 15 can be observed through the observation port 29, and each observation port 29 is kept stable by the closed glass 30. When the primary filter 4 and the purification filter 16 are working, it can be observed through the observation port 29. If there is foreign matter attached to the primary filter 4 or the purification filter 16, the pulling rod 18 can be controlled. Under the action of the sliding seal 17, the cleaning scraper 19 is controlled to move by the pulling rod 18. When the cleaning scraper 19 moves, the guide blocks 21 at both ends thereof move in the guide groove 20. The guide groove 20 restricts the guide block 21, so that the movement of the cleaning scraper 19 remains stable. The surface of the purification filter 16 is cleaned by the moving cleaning scraper 19 to avoid foreign matter attached to the filter during filtration and causing blockage. The above structure and method are also used for cleaning the primary filter 4, and when the guide block 21 moves along the guide groove 20, it will contact the guide groove 20 through the cleaning blocks 22 at both ends. When moving, the foreign matter in the guide groove 20 is cleaned by the cleaning block 22 to avoid foreign matter remaining in the guide groove 20, which causes the movement of the cleaning scraper 19 to be blocked. When processing the sediment in the sedimentation box 2, the corresponding control valve 25 on the water inlet pipe 3 is closed to stop the water supply to the sedimentation box 2, and the water in the sedimentation box 2 is discharged as much as possible, and then the discharge door 26 is opened to discharge the residual water and sediment inside from the discharge door 26, and the hydraulic rod 27 is controlled to provide power to move the cleaning push plate 28 to push the sediment out, so as to facilitate the processing of deeper sediment.

[0046] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
