Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically to an active bacteria concentration booster. Background Technology

[0002] The concentration of active bacteria (i.e., activated sludge concentration) refers to the content of suspended solids in the mixed liquor at the outlet of the reactor. Its unit is mg / L. It is used to measure the number of active bacteria in the reactor. In wastewater treatment, microbial preparation and high-efficiency fermentation, the concentration and activity of active bacteria directly affect the start-up time, treatment efficiency and stability of the system.

[0003] Publication number CN212864288U discloses an active bacteria concentration booster, which includes a booster body with an inverted conical bottom that is sealed. A central guide pipe is located at the center of the booster body, and a reflector plate is located at a certain distance from the bottom of the central guide pipe. An inlet pipe is located on the left side of the booster body and is connected to the central guide pipe. An outlet overflow trough and an active bacteria overflow weir are located at the top of the booster. An air lift pipe is located on one side of the active bacteria overflow weir and is connected to the bottom of the booster body. An air lift pipe is connected to one side of the air lift pipe. This solves the problem of a large amount of active bacteria being carried away by the effluent. It also eliminates the need for a sedimentation tank and a sludge return system in the system, allowing the active bacteria to be successfully retained in the reaction tank. This reduces the total amount of mechanical equipment, reduces power consumption, and also lowers the system operating cost.

[0004] Existing active bacteria concentration boosters, after injecting wastewater carrying active bacteria, utilize sedimentation separation between the active bacteria and wastewater to allow the active bacteria particles to sink to the bottom of the container, while the clear liquid separated from the top overflows naturally from the top of the container, thereby reducing the system's operating costs. However, when the wastewater carrying active bacteria enters the container through the inlet pipe, it first comes into contact with a reflector plate located below the inlet. Although the reflector plate can transform the downward water flow into a radially distributed flow pattern around the plate surface, thus buffering and dispersing the water flow, it also generates impact and disturbance, causing some active bacteria particles to be dispersed and suspended, and then flow out with the supernatant, reducing the bacteria recovery rate. To address this, we propose an active bacteria concentration booster. Utility Model Content

[0005] The purpose of this invention is to provide an active bacterial strain concentration enhancer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, an active bacterial strain concentration booster includes a booster body, with a water overflow outlet at the top of the booster body, a water inlet pipe on one side of the water overflow outlet, an air lift pipe on the lower side of the water overflow outlet, and an active bacterial strain extraction weir connected to the lower side of the air lift pipe.

[0007] The outlet end of the inlet pipe is provided with a separation mechanism, which includes a conical base. The conical base is located at the outlet end of the inlet pipe. The wastewater carrying active bacteria at the outlet end of the inlet pipe flows tangentially into the interior of the conical base and around the inner wall of the conical base. The bottom of the conical base is provided with a discharge hole, and the top of the conical base is provided with a laminar flow plate.

[0008] Furthermore, the interior of the elevator body has several laminar flow plates on the upper side of the separation mechanism.

[0009] Furthermore, the bottom of the inner wall of the lifting device body is conical.

[0010] Furthermore, a baffle is provided between the water overflow outlet and the active bacteria extraction weir, and the height of the baffle is higher than the height of the water overflow outlet.

[0011] Furthermore, the top of the overflow outlet is provided with spaced V-shaped notches.

[0012] Furthermore, the upper end of the air lifting pipe is connected to the input end of a pump.

[0013] Furthermore, the angle between the laminar flow plate and the horizontal plane is 55° to 60°.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the separation mechanism and laminar flow plate reduce the sewage flow rate and increase the settling opportunity of active bacteria particles, preventing the overflow of mixed bacteria in the supernatant. There is no need to screen out active bacteria with filter media, so no manual cleaning is required, and the effect of increasing the concentration of active bacteria is obvious.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 The figure shows a preferred embodiment of the present invention, an active bacteria concentration booster, including a booster body 1, a water overflow port 2 at the top of the booster body 1, a water inlet pipe 3 on one side of the water overflow port 2, an air lift pipe 4 on the lower side of the water overflow port 2, and an active bacteria extraction weir 5 connected to the lower side of the air lift pipe 4.

[0022] The outlet end of the inlet pipe is equipped with a separation mechanism 6, which includes a conical base 7. The conical base 7 is located at the outlet end of the inlet pipe. The wastewater carrying active bacteria at the outlet end of the inlet pipe is tangential to the interior of the conical base 7 and flows around the inner wall of the conical base 7. The bottom of the conical base 7 is equipped with a discharge hole 8, and the top of the conical base 7 is equipped with a laminar flow plate 10.

[0023] Specifically, the interior of the elevator body 1 has several laminar flow plates 10 on the upper side of the separation mechanism 6, which extends the flow path of the water from bottom to top and increases the residence time. This gives the active bacteria in the water more opportunities to aggregate and sink, returning to the bacterial pool at the bottom of the elevator body 1.

[0024] The bottom of the inner wall of the elevator body 1 is conical, which reduces the chance of sludge being carried into the overflow.

[0025] Understandably, in order to prevent the supernatant flowing out of the overflow outlet 2 from entering the active bacteria extraction weir 5, a baffle 11 is provided between the overflow outlet 2 and the active bacteria extraction weir 5, and the height of the baffle 11 is higher than the height of the overflow outlet 2.

[0026] Among them, the top of the water overflow outlet 2 is provided with V-shaped notches distributed at intervals, so that the water flow forms a thin film flow in the tiny gaps. Fine particles are not easily carried away by the high-speed water flow in the thin film, but will fall back along the edge of the notch.

[0027] Specifically, the upper end of the air lift pipe 4 is connected to the input end of the pump. After the pump is started, the mud is discharged from the active bacteria extraction weir 5 through the air lift pipe 4.

[0028] The laminar flow plate 10 has an angle of 55-60° with the horizontal plane to balance settling efficiency and anti-clogging during sludge settling and automatic fall-off.

[0029] In this embodiment, the wastewater carrying active bacteria first enters the separation mechanism 6 through the inlet pipe 3. The wastewater carrying active bacteria at the outlet of the inlet pipe 3 is tangential to the inside of the conical base 7 and flows around the inner wall of the conical base 7 before entering the inner side of the conical base 7. The wastewater is initially slowed down and the active bacteria particles settle and agglomerate. The sludge falls from the conical base 7 into the bacterial pool at the bottom of the elevator body 1 through the discharge hole 8. The clear liquid overflows from the top of the vertical cylinder 9. As the wastewater continues to flow into the elevator body 1, the water level also rises continuously. During the process, several laminar flow plates 10 extend the flow path of the water from bottom to top and increase the residence time. The active bacteria in the water have more opportunities to agglomerate and settle, returning to the bacterial pool at the bottom of the elevator body 1. The clarified supernatant overflows from the outlet overflow port 2. The sludge accumulated in the bacterial pool at the bottom of the elevator body 1 is discharged from the active bacteria extraction weir 5 through the air lift pipe 4 after the pump is started.
