Specific embodiments

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-3 , the present invention provides a technical solution: a corrugated board energy-saving and emission-reduction sewage treatment device, including a box body 1 and a solar power supply device. The box body 1 is made of corrugated board. A box cover 29 is hinged to the top of the box body 1. A filter box 2 and an anaerobic box 3 are arranged on one side of the inner wall of the box body 1. The anaerobic box 3 is arranged at the bottom of the inner wall of the box body 1, and the anaerobic box 3 is fixed at the bottom of the filter box 2. A sedimentation tank 4 is arranged inside the filter box 2 and near the upper side. The vertical layout reduces the occupied space.

[0028] A water inlet pipe 20 is communicated with one side of the sedimentation tank 4. One end of the water inlet pipe 20 is connected to the domestic sewage discharge outlet. A cleaning box 5 is arranged inside the sedimentation tank 4. The bottom of the sedimentation tank 4 is located inside the filter box 2. A fixed seat 18 is fixedly connected to the inner wall of the filter box 2 and near the bottom position. Fixing rods 19 are fixedly connected to the four sides of the sedimentation tank 4. The fixing rods 19 are located above the fixed seat 18. The fixing of the sedimentation tank 4 is realized through the fixing rods 19 and the fixed seat 18, and it is also convenient for the sedimentation tank 4 to be separated from the filter box 2.

[0029] The cleaning tank 5 includes a collection tank 51 and a fixing frame 52. The fixing frame 52 is located above the collection tank 51. A connecting rod 53 is fixedly connected between the top of the collection tank 51 and the bottom of the fixing frame 52. A filter plate 54 is also fixedly connected to the middle of the connecting rod 53. The cleaning tank 5 is installed behind the sedimentation tank 4, and the filter plate 54 is located above the water inlet pipe 20. Two sides of the top of the fixing frame 52 are also fixedly connected with handles 55. After the domestic sewage in the water inlet pipe 20 enters the sedimentation tank 4, the sedimentation tank 4 is first filled, and then the water overflows from the top of the sedimentation tank 4 and flows into the filter tank 2. The sediment in the domestic sewage accumulates in the collection tank 51, and at the same time, the floating substances in the water also accumulate in the sedimentation tank 4 due to the blocking of the filter plate 54.

[0030] In the filter tank 2, a first filter layer 6 and a second filter layer 7 are arranged in sequence from top to bottom. The first filter layer 6 uses coarse sand, and the second filter layer 7 uses fine sand. The coarse sand is gravel with a particle size greater than 1 mm, and the fine sand is gravel with a particle size less than 0.5 mm. The thickness of the first filter layer 6 is 20 - 50 cm, and the thickness of the second filter layer 7 is 20 - 60 cm. Through the graded filtration of the coarse sand and the fine sand, the particulate matter in the water is reduced.

[0031] A first guide plate 16 is fixedly connected to the inner wall of the filter tank 2 and located in the first filter layer 6. The first guide plate 16 is in the shape of an inverted quadrangular pyramid, and filter holes are evenly distributed on the surface of the first guide plate 16. Through the guiding effect of the first guide plate 16, it is ensured that the water overflowing from the four sides of the top of the sedimentation tank 4 can be distributed in the first filter layer 6, avoiding concentrated filtration and improving the filtration effect.

[0032] A second guide plate 17 is fixedly connected to the inner wall of the filter tank 2 and located at the bottom of the second filter layer 7. The second guide plate 17 has a symmetrically inclined structure, and leakage holes are arranged on the surface of the second guide plate 17 and close to the lower side of the inner wall of the filter tank 2. Through the second guide plate 17, it is ensured that the filtered water flows to one side of the connecting pipe 8 through the leakage holes, and at the same time, the fine sand is also prevented from flowing into the connecting pipe 8.

[0033] A connecting pipe 8 is arranged between the bottom of the filter tank 2 and the top of the anaerobic tank 3. A discharge pipe 9 is arranged on one side of the anaerobic tank 3 and close to the top position. The connecting pipe 8 has an S-shaped structure, the discharge pipe 9 is vertically arranged and extends above one side of the anaerobic tank 3, and one end of the discharge pipe 9 is set in a U shape, using water to seal the anaerobic tank 3 to ensure an anaerobic environment inside.

[0034] On both sides of the inner wall of the box body 1, there are vertically fixedly connected guide rails 10. A regulating plate 11 is slidably connected to the surface of the guide rails 10. The bottom of the regulating plate 11 is fixedly connected with an aeration disc 12. The air outlet of the aeration disc 12 faces the bottom of the box body 1. One side of the aeration disc 12 is communicated with an aeration pipe 13. The top of the regulating plate 11 is fixedly connected with a storage box 14 and an air bag 15. Ceramic rings are arranged in the storage box 14, and the ceramic rings provide attachment and reproduction places for nitrifying bacteria. An aeration fan 30 is arranged on one side of the box body 1. The air outlet end of the aeration fan 30 is communicated with one end of the aeration pipe 13. When the aeration disc 12 works, the regulating plate 11 is driven by the buoyancy of the air bag 15 in the water to move along the length direction of the guide rail 10 towards one side of the top of the box body 1. When the aeration disc 12 stops working, the regulating plate 11 moves along the length direction of the guide rail 10 towards one side of the bottom of the box body 1. Through the mobility of the regulating plate 11, the aeration effect is further optimized, ensuring that the sewage fully contacts oxygen and accelerating the decomposition of organic matter.

[0035] An overflow pipe 21 communicating with the outside is arranged on one side of the box body 1. The horizontal plane where the overflow pipe 21 is located is lower than the horizontal plane where the top of the filter box 2 is located, preventing the water in the box body 1 from entering the filter box 2. One end of the overflow pipe 21 can be communicated with an irrigation reservoir to realize the utilization of water resources. To increase the sterilization effect, ultraviolet germicidal lamps can be arranged in the box body 1.

[0036] The solar power supply device includes a solar photovoltaic panel 22, a solar controller 23, an inverter 24 and a storage battery 25. It also includes a vertical pole 26. The solar photovoltaic panel 22 is fixed on the top of the vertical pole 26 through a bracket. A control box 27 and an equipment box 28 are arranged on the surface of the vertical pole 26. The solar controller 23 and the inverter 24 are arranged in the control box 27. The aeration fan 30 and the storage battery 25 are arranged in the equipment box 28. Using solar energy to supply power to the equipment reduces the dependence on traditional electric energy and achieves the purpose of energy conservation and emission reduction.

[0037] When domestic sewage enters the sedimentation tank 4 from the water inlet pipe 20, the sediment and floating substances are removed through the sedimentation tank 4, and then enter the anaerobic tank 3 through the two-stage filtration of the filter box 2. Anaerobic microorganisms are used to decompose organic matter, and then it is discharged into the box body 1 through the discharge pipe 9. The oxygen content is increased through the aeration disc 12 to further promote biodegradation, and finally it flows out from the overflow pipe 21.
