[0032] This application discloses a comprehensive purification system for high-concentration kitchen waste wastewater.

[0033] Reference Figure 1-3A high-concentration kitchen waste wastewater comprehensive purification system includes a reaction chamber 1. A top cover 2 is fixedly connected to the outer wall of the top of the reaction chamber 1. A sludge discharge trough is opened on the inner wall of the bottom of the reaction chamber 1. The same auger 14 is rotatably connected to the inner walls of both sides of the sludge discharge trough. A sludge discharge port is opened on one side of the inner wall of the sludge discharge port. A sealing cover 8 is hinged to the inner wall of the sludge discharge port. Mounting boxes 13 are fixedly connected to the inner walls of both sides of the reaction chamber 1. Rotating seats 15 are rotatably connected to the inner walls of both sides of the two mounting boxes 13. Multiple cleaning nozzles 16 are fixedly connected to the outer wall of the bottom of both rotating seats 15.

[0034] In use, a sludge discharge trough is opened at the bottom of the reaction tank 1 to facilitate the collection of sludge in the reaction tank 1. The sludge in the sludge discharge trough is discharged through the sludge discharge port by the screw conveyor 14. The installation box 13 is set to facilitate the rotation installation of the rotating seat 15. When the rotating seat 15 rotates, it directly drives the cleaning nozzle 16 to swing, thereby expanding the rinsing range of the cleaning nozzle 16. High-concentration kitchen wastewater is first separated into oil and water by a three-phase centrifugal separator. Then, the separated water phase is injected into the physicochemical reactor for further treatment with chemicals. After treatment, the water phase is transported to the inclined plate sedimentation equipment for further sedimentation. After sedimentation, the sludge is discharged into the sludge tank, and the water phase is transported to the water tank and then treated by biological water purification.

[0035] Reference Figure 3-5 Two water inlet pipes 7 are fixedly connected to one side of the outer wall of the auxiliary wastewater reaction tank 1, and the two water inlet pipes 7 are respectively connected to the cleaning nozzle 16 through pipes. Two drive boxes 9 are fixedly connected to one side of the outer wall of the reaction tank 1, and gears 19 are rotatably connected to one side of the inner wall of each of the two drive boxes 9. One end of the drive shaft of the two gears 19 is fixedly connected to two rotating seats 15 respectively. A servo motor 17 is fixedly connected to one side of the inner wall of the drive box 9, and a missing gear 18 is fixedly connected to the output shaft of the servo motor 17. The missing gear 18 and the gear 19 The components mesh with each other. The setup of the reaction chamber 1 facilitates the installation of the water inlet pipe 7. The water inlet pipe 7 is connected to an external water pump, which works in conjunction with the cleaning nozzle 16 to rinse the inner wall of the reaction chamber 1. The setup of the drive box 9 facilitates the rotation of the gear 19. When the gear 19 rotates, it directly drives the rotating seat 15 to move, thereby rinsing the cleaning nozzle 16. The start of the servo motor 17 drives the missing gear 18 to rotate. When the missing gear 18 rotates, it directly drives the gear 19 to rotate, thereby facilitating the adjustment of the angle of the cleaning nozzle 16 to expand the rinsing range.

[0036] Reference Figure 1-2A motor 10 is fixedly connected to one side of the outer wall of the reaction tank 1, and a pulley 1 is fixedly connected to the output shaft of the motor 10. A pulley 2 connected to the auger 14 is rotatably connected to one side of the outer wall of the reaction tank 1, and the same belt 11 is connected between the pulley 2 and the pulley 1. The motor 10, in conjunction with the belt 11, directly drives the auger 14 to rotate. When the auger 14 rotates, it is convenient to directly discharge the sludge in the sludge discharge tank.

[0037] Reference Figure 1-3 The auxiliary reaction tank 1 is sealed by a top cover 2, which is rotatably connected to the bottom outer wall of the top cover 2. A motor 4 is fixedly connected to the top outer wall of the top cover 2, and the output shaft of the motor 4 is fixedly connected to the stirring frame 12. A dosing port is provided on the top outer wall of the top cover 2, and a dosing pipe 3 is fixedly connected to the inner wall of the dosing port.

A drain outlet is provided on one side of the outer wall of the reaction tank 1, and an L-shaped drain pipe 6 is fixedly connected to the inner wall of the drain outlet. The motor 4 allows for direct rotation of the stirring frame 12, which directly stirs the wastewater in the reaction tank 1. The dosing pipe 3 facilitates the addition of chemicals to the reaction tank 1. The cover plate 5 facilitates the sealing of the feed outlet. The L-shaped drain pipe 6 facilitates the direct discharge of the aqueous phase that has completed the reaction in the reaction tank 1.

[0038] The implementation principle of the high-concentration kitchen waste wastewater comprehensive purification system in this application embodiment is as follows: During use, the wastewater is first transported to the reaction tank 1 through the feeding port, and then the motor 4 is started to drive the stirring frame 12 to rotate. At the same time, the chemical solution is injected into the reaction tank 1 through the dosing pipe 3. When the stirring frame 12 rotates, it stirs and mixes the wastewater in the reaction tank 1. The sediment in the wastewater enters the sludge discharge tank. Then, the water in the reaction tank 1 is extracted through the drain pipe 6. After the water after the reaction is extracted, the sealing cover 8 is opened, and the motor 10 is started to drive the auger 14 to rotate in conjunction with the belt 11. When the auger 14 rotates, it is convenient to directly discharge the sludge and sediment in the sludge discharge tank. During the cleaning process, the water inlet pipe 7 is connected to the water pump, and the inner wall of the reaction tank 1 is rinsed through the cleaning nozzle 16. During rinsing, the servo motor 17 drives the gear 18 to rotate. When the gear 18 rotates, it directly drives the gear 19 to rotate, which in turn facilitates the swinging of the cleaning nozzle 16 to expand the rinsing range.
