[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be understood that the following specific embodiments are only exemplary explanations, and those skilled in the art can further make technical extensions based on the design ideas of the following specific technical solutions, and such technical extensions should fall within the scope of protection of the utility model.

[0025] Embodiment: A multi-tank vertical sewage separation device, as shown in the attached Figures 1 to 4 As shown, it includes a fermentation tank 1 and a biochemical tank 2; in this embodiment, a double tank design is adopted, which only includes a fermentation tank 1 and a biochemical tank 2. In order to improve the decomposition and purification effect, those skilled in the art may also set a tank body for further auxiliary decomposition between the fermentation tank 1 and the biochemical tank 2. Therefore, this method of adding an auxiliary tank is not the design focus of the technical solution and will not be described in detail in this embodiment.

[0026] In this embodiment, the fermentation tank 1 and the biochemical tank 2 are both vertical tank bodies, and the tank bodies of the fermentation tank 1 and the biochemical tank 2 are both elliptical egg-shaped structures, and the bottom cross-sections of the two are reduced to form a fermentation tank variable diameter area 10 and a biochemical tank variable diameter area 20 respectively.

[0027] The fermentation tank 1 is vertically provided with a fermentation inner tank 3, and the top of the fermentation inner tank is designed as an outer flange structure and is fixed by rivets at the top edge of the fermentation tank. Figure 3 , 4 As shown, a separation interlayer 14 is provided between the fermentation tank 1 and the inner fermentation tank 3, and the separation interlayer 14 is connected to the bottom of the fermentation tank, that is, the inner fermentation tank 3 does not extend to the bottom of the fermentation tank 1, and usually a gap of about 20 cm is left; a water supply pipe 13 is provided inside the fermentation tank 1, and the water supply pipe 13 passes through the side walls of the fermentation tank 1 and the inner fermentation tank 3 and extends to the interior of the inner fermentation tank 3; a separation drain pipe 15 is provided on the upper part of the separation interlayer 14 and is connected to the biochemical tank water inlet pipe 17 on the biochemical tank 2.

[0028] A biochemical inner tank 4 is arranged inside the biochemical tank 2, and an outer interlayer 22 is arranged between the biochemical tank 2 and the biochemical inner tank 4. The biochemical inner tank 4 is combined with the biochemical tank 2 in exactly the same way, that is, the biochemical inner tank 4 does not extend to the bottom surface of the biochemical tank 2, and usually a gap of about 20 cm is left. This structure enables the outer interlayer 22 to be connected to the bottom of the biochemical tank 2; a grid filler bracket 7 is arranged inside the biochemical inner tank 4, and a hanging filler 9 is fixed at a single point on the grid filler bracket 7.

[0029] Furthermore, the utility model is provided with a grid hole 71 on the grid filler support 7, and the hanging filler 9 is fixed by the grid hole 71. When the hanging filler 9 is fixed, the upper end of the hanging filler 9 is fixed at a single point on the grid filler support 7 and the lower end of the hanging filler 9 is not fixed, and is suspended in the biochemical inner tank 4.

[0030] The purpose of setting such a hanging filler 9 is to promote the attachment of aerobic bacteria, and to enhance the aggregation and reproduction of aerobic bacteria. An aeration pipe 5 is arranged inside the biochemical inner tank 4, and the aeration pipe 5 extends to the floating area below the hanging filler 9 and is provided with a gas diffusion device at the end of the aeration pipe 5. The gas diffusion device is a gas exhaust pipe 8, and the gas exhaust pipe 8 includes a main pipe 81, and a plurality of branch pipes 82 are arranged on the main pipe 81. The branch pipe 82 is provided with a plurality of air holes 83. The branch pipe 82 can adopt a combination of different lengths according to the cross section of the inner cavity of the biochemical inner tank 4 to achieve the maximum gas supply.

[0031] This kind of suspended filler 9 is arranged in a strip structure, such as Figure 6 As shown, it includes a steel wire fixing part 91 at the center, the steel wire fixing part 91 is a stainless steel cable, and its outer periphery is coated with anti-corrosion glue. A mesh or flocculent parasitic blade 92 is wound and fixed on the steel wire fixing part 91. This parasitic blade 92 is composed of a hairy ring. This design can increase the attachment space of aerobic bacteria. The utility model designs the hairy ring into multiple rows and arranges it in a spiral shape around the steel wire fixing part 91. The purpose of this design is that when a plurality of branch pipes 82 supply air, the air flow or water flow is disturbed to touch the hairy ring to the maximum extent, so as to promote the shedding of the aged biofilm of aerobic bacteria on the hairy ring, promote the reproduction and growth of new biofilm, and also promote the combination of aerobic bacteria and organic matter to improve the decomposition efficiency.

[0032] A drain pipe 21 is disposed on the upper portion of the outer discharge interlayer 22 and is in communication with the outside, and the purified liquid can be discharged to the outside through the drain pipe 21 .

[0033] In order to improve the overall strength of the fermentation tank 1 and the biochemical tank 2, the utility model adopts a cross arrangement of latitudinal reinforcement ribs 11 and radial reinforcement ribs 12 on the outer walls of the fermentation tank 1 and the biochemical tank 2. Such reinforcement ribs are protruded from the outer wall to achieve overall reinforcement.

[0034] During assembly of the utility model, a hose 16 is used between the fermentation tank 1 and the biochemical tank 2 to connect the separation drain pipe 15 with the biochemical tank water inlet pipe 17. The hose 16 can compensate for the docking gap between the fermentation tank 1 and the biochemical tank 2 during installation, and the gap includes front-to-back spacing, left-right spacing, and top-to-bottom spacing.

[0035] The working principle of the utility model is: Figure 4 As shown, after being filtered, the external domestic sewage enters the fermentation inner tank 3 in the fermentation tank 1 through the water supply pipe 13. At this time, the fermentation tank 1 functions as a septic tank, and the sewage flows down in the fermentation inner tank 3 to the fermentation tank variable diameter area 10. The fermentation tank variable diameter area 10 is a cone-shaped design. After anaerobic decomposition, carbon dioxide floats together with solid dirt and oil, and continues to decompose with anaerobic microorganisms. The heavier decomposition products are gradually deposited in the fermentation tank variable diameter area 10, and the lighter impurities float to the top of the fermentation tank 1. The decomposed liquid flows upward through the separation interlayer 14 and is finally diverted to the biochemical tank inlet pipe 17 through the separation drain pipe 15.

[0036] After primary anaerobic decomposition is achieved in the fermentation tank 1, the liquid after anaerobic separation is directed to the biochemical tank 2, and the sewage is terminally treated through internal aerobic decomposition. Specifically, the separated liquid enters the biochemical inner tank 4 inside the biochemical tank 2, and the liquid flows downward in the biochemical inner tank 4. The liquid passes through the suspended filler 9 and is fully in contact with the parasitic blades 92. The aerobic bacteria on the hair-like ring aerobically decompose the organic matter. During the decomposition, the aeration pipe 5 is combined with the exhaust pipe 8 to supply oxygen to the fixed area of ​​the suspended filler 9. During the aeration, the aged biofilm of aerobic bacteria attached to the suspended filler 9 also falls off, and at the same time, the combination of aerobic bacteria and organic matter is promoted to improve the decomposition efficiency. After continuous aerobic decomposition, the liquid is separated into solid and liquid, and the solid sediment is collected and concentrated through the tapered biochemical tank variable diameter area 20. At this time, the oxygen supply valve 51 can be adjusted to increase the air supply of the aeration pipe 5 to continuously disturb the solid matter to turn over. The turned-up solid organic matter continues to combine with the aerobic bacteria on the hair-like ring on the parasitic blade 92 to undergo aerobic biochemical reaction again.

[0037] After a long period of action, the above-mentioned aerobic bacteria biochemical reaction will gradually form organic sediments in the biochemical tank variable diameter area 20. To achieve cleaning, the biochemical inner tank 4 is provided with a cleaning pipe 6, which vertically penetrates the grid filler bracket 7 and extends into the biochemical tank variable diameter area 20. The organic sediments can be removed by cooperating with the external sewage suction equipment. The working principle of this sewage suction is the same as that of the existing fecal suction truck, and no details are given here.

[0038] After anaerobic decomposition and aerobic decomposition, the liquid that meets the standards flows upward in the outer discharge interlayer 22 and is discharged to the outside through the drain pipe 21. The utility model designs the drain pipe as a right-angle elbow, and the part arranged inside the outer discharge interlayer 22 is an upper opening. The liquid that meets the standards is automatically discharged to the outside in a static overflow manner, which can further ensure that the liquid discharged is sewage that reaches the inner surface of the tank after the suspended matter is fully precipitated.

[0039] The utility model has high domestic sewage treatment effect, high efficiency, thorough sewage treatment, small size, and easy maintenance. It is suitable for popularization and use with families as installation units and is an ideal multi-tank vertical sewage separation device.
