Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a small corrugated board sewage treatment device. Background Art

[0002] With the rapid development of rural economy and the improvement of residents' living standards, the discharge of rural domestic sewage has increased significantly. However, the corresponding sewage treatment facilities are relatively lagging behind, resulting in a large amount of untreated sewage being directly discharged, seriously polluting the rural environment and underground water bodies. Traditional large-scale sewage treatment facilities not only have high construction costs and large floor areas, but also have complex operation and maintenance, which are not suitable for the actual situation in rural areas. Therefore, it is particularly important to develop a device with low cost, small floor area, simple operation and effective treatment of rural domestic sewage.

Detailed implementation manner

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-4 , the present invention provides a technical solution: a corrugated board small sewage treatment device, including a box body 1, the box body 1 is buried underground, the bottom of one side of the inner wall of the box body 1 is fixedly connected with a treatment box 2, the top of the box body 1 and at the corresponding position of the treatment box 2 is hinged with a first box cover 31, one side of the first box cover 31 is hinged with a second box cover 32, the first box cover 31 and the second box cover 32 are located above the ground, the box body 1 and the treatment box 2 are made of corrugated board. Using corrugated board material not only reduces the weight of the equipment but also enhances the structural strength. Setting the treatment box 2 inside the box body 1 reduces the floor area.

[0029] The top of the treatment box 2 is provided with a sedimentation tank 3, one side of the box body 1 is provided with a water inlet pipe 4, one side of the sedimentation tank 3 is communicated with a water injection pipe 5, one end of the water inlet pipe 4 is communicated with the water injection pipe 5. Opening the second box cover 32 facilitates directly taking the treated water from inside the box body 1, and opening the first box cover 31 facilitates cleaning the sedimentation tank 3.

[0030] The sedimentation tank 3 includes a tank body 301. There is a flanging 302 fixedly connected to the periphery of the top of the tank body 301. The sedimentation tank 3 is fixed to the top of the treatment tank 2 through the flanging 302. A filter plate 303 is also arranged in the tank body 301. The filter plate 303 is fixed in the tank body 301 by snap fasteners. When cleaning the sediment at the bottom of the tank body 301, the tank body 301 needs to be taken out and the filter plate 303 removed. An inlet hole 304 is arranged on one side of the tank body 301 and below the filter plate 303. Through holes 305 are formed on the surface around the tank body 301 and above the filter plate 303. When sewage enters from the inlet hole 304, impurities precipitate in the tank body 301, and at the same time, floating matters are also blocked in the tank body 301 by the filter plate 303. Subsequently, the water overflows from the through holes 305 and flows into the treatment tank 2.

[0031] A baffle 306 is fixedly connected inside the tank body 301 and below the filter plate 303. There are multiple baffles 306 arranged in a staggered manner. The baffle 306 can reduce the outflow of sediment with the water flow from the through holes 305.

[0032] A first fixing plate 6, a second fixing plate 7 and a third fixing plate 8 are fixedly connected inside the treatment tank 2 from top to bottom in sequence. Through holes are arranged on the surface of the first fixing plate 6. A first filtering layer 9 and a second filtering layer 10 are arranged on the top of the first fixing plate 6 from top to bottom. The first filtering layer 9 uses coarse sand, and the second filtering layer 10 uses fine sand. The coarse sand is gravel with a particle size greater than 3 mm, and the fine sand is gravel with a particle size less than 1 mm. The thicknesses of the first filtering layer 9 and the second filtering layer 10 are 20 - 60 cm. Through the hierarchical filtration of the coarse sand and the fine sand, the particulate matters in the water are reduced.

[0033] A first connecting pipe 11 is arranged on the surface of the second fixing plate 7, and a second connecting pipe 12 is arranged on the surface of the third fixing plate 8. A clear water pipe 13 is arranged on one side of the treatment tank 2 and below the third fixing plate 8. The tops of the first connecting pipe 11 and the second connecting pipe 12 are set in an inverted U-shaped structure, and the clear water pipe 13 is a U-shaped pipe, realizing a closed state inside, which is convenient for anaerobic treatment.

[0034] On both sides of the inner wall of the box body 1, there are vertically fixedly connected guide rails 14. The two ends of the guide rails 14 are provided with limit blocks. The surface of the guide rails 14 is slidably connected with a connecting frame 15. The bottom of the connecting frame 15 is fixedly connected with an aeration disc 16. It also includes an equipment box 23. Inside the equipment box 23, there are an aeration fan 24, a controller 25 and a storage battery 26. A ventilation pipe 27 is connected between the air outlet end of the aeration fan 24 and one end of the aeration disc 16. The air outlet of the aeration disc 16 faces the bottom of the box body 1. A storage box 17 and an air bag 18 are also arranged at the top of the connecting frame 15. When the aeration disc 16 is ventilated, the connecting frame 15 moves upward along the length direction of the guide rail 14. After the aeration disc 16 stops ventilating, the connecting frame 15 moves downward along the length direction of the guide rail 14. Through the mobility of the connecting frame 15, the aeration effect is further improved, ensuring that the sewage fully contacts oxygen and accelerating the decomposition of organic matter.

[0035] On one side of the box body 1, there is also an overflow pipe 19. The height of the overflow pipe 19 is lower than the position of the water inlet pipe 4, ensuring that water can flow out from the overflow pipe 19 when there is too much water. A pump support 20 is also fixedly connected to the inner wall of the box body 1. The pump support 20 includes a fixing plate 201. The surface of the fixing plate 201 is provided with installation grooves 202. There are two installation grooves 202 and they are arranged in parallel. The installation grooves 202 are blind grooves. On one side of the fixing plate 201, there is a pump body fixing ring 204. A fixing rod 205 is fixedly connected between the two pump body fixing rings 204. A slider 203 is fixedly connected to one side of the pump body fixing ring 204. The slider 203 is slidably connected with the installation groove 202. A pump body 21 is arranged inside the pump support 20. The water outlet end of the pump body 21 is communicated with a drain pipe 22. The installation of the pump body 21 is facilitated by the pump support 20. The pump body 21 is connected to the controller 25, facilitating the use of the pump body 21 for irrigation.

[0036] It also includes a solar photovoltaic module 28. The solar photovoltaic module 28 is electrically connected to the storage battery 26. The solar photovoltaic module 28 includes a photovoltaic panel, a solar controller and an inverter, providing clean energy and conforming to the development concept of green and low-carbon.

[0037] The second fixing plate 7 and the third fixing plate 8 are inclined. Sealing covers 29 are arranged at the top positions on the lower sides of the second fixing plate 7 and the third fixing plate 8 on the surface of the treatment tank 2. The inclination angle is 5 - 20 degrees, facilitating the concentration of sludge on one side and convenient for cleaning.

[0038] The surface of the storage box 17 is provided with through holes. A bacteria house 30 is arranged inside the storage box 17. The bacteria house 30 is used for cultivating and breeding microorganisms to improve the treatment effect.
