[0019] The embodiments of the present application will be described in detail below with reference to the drawings. It should be clear that the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0020] As shown in Figs. 1-2 In some illustrative embodiments, a bacteria sludge mixing device under the magnetic field strengthening is provided, which comprises: a shell box 100, a top plate magnet 200, a bottom plate magnet 300, a serpentine mixing main pipeline 400, a bacteria injection auxiliary pipeline 500, a pressure sensor 600, a handle 700, a control panel 800, a controller, a pipeline support 910, a boom 920 and a clamp 930.

[0021] The shell box 100 is a hollow cuboid shell, which is used to accommodate the components required in the mixing process and protect the internal structure. The top plate magnet 200 and the bottom plate magnet 300 are respectively arranged at the top and bottom of the shell box 100, and together form a magnetic field of 15mT inside the shell box 100. Among them, the top plate magnet 200 and the bottom plate magnet 300 can be realized by placing a plurality of permanent magnets, for example, using some small neodymium iron boron permanent magnet blocks, which are arranged in an array. The size and distribution of the magnetic field can be accurately controlled by adjusting the position and number of permanent magnets, so as to ensure that the serpentine mixing main pipeline 400 is always in a stable magnetic field environment.

[0022] A serpentine mixing main pipe 400 is located inside the outer casing 100. The serpentine design helps to increase the flow path of the fluid within the pipe, thereby enhancing the mixing effect. An inlet gate 130 is provided on one side of the outer casing 100, and an outlet gate 140 is provided on the other side. The inlet gate 130 is used to introduce bacteria and sludge, while the outlet gate 140 is used to output the mixed material.

[0023] A feed inlet 150 is provided on the feed gate plate 130, which is connected to the feed end of the serpentine mixing main pipeline 400. The feed inlet 150 includes a microbial inlet 151 and a sludge inlet 152. The microbial inlet 151 is used to connect with the pipeline transporting microbial inoculum to ensure that the microbial inoculum can smoothly enter the serpentine mixing main pipeline 400. The sludge inlet 152 is used to connect with the pipeline transporting sludge, so that the sludge and microbial inoculum can be mixed in the same pipeline. A discharge inlet 160 is provided on the discharge gate plate 140, which is connected to the discharge end of the serpentine mixing main pipeline 400. The discharge inlet 160 is connected to the biological treatment tank through an external pipeline, that is, the mixed microbial inoculum and sludge are transported to the biological treatment tank for further biological treatment through the external pipeline.

[0024] The entire process of the device is as follows: sludge and bacteria enter the serpentine mixing main pipe 400 through sludge interface 152 and bacteria interface 151 respectively. In the serpentine mixing main pipe 400, sludge and bacteria are fully mixed under the action of a magnetic field. The mixed bacteria and sludge flow out through discharge interface 160 and are transported to the biological treatment tank through the external pipeline to participate in the biological treatment process.

[0025] Existing research has shown that magnetic fields can have multifaceted effects on microorganisms. On the one hand, magnetic fields can alter the charge distribution and cell membrane permeability of microbial cells, promoting the absorption of nutrients and the excretion of metabolic products, thereby increasing the growth rate and metabolic activity of microorganisms. On the other hand, magnetic fields can affect the activity of enzymes within microorganisms, making them more conducive to catalyzing biochemical reactions related to pollutant degradation. Simultaneously, magnetic fields also improve the properties of sludge itself; they can reduce sludge viscosity and surface charge, making sludge particles easier to disperse and aggregate, facilitating thorough mixing and contact between microorganisms and sludge, and improving treatment efficiency.

[0026] In this application, during the mixing process of microorganisms and sludge, the magnetic field inside the outer casing 100 is formed by the top plate magnet 200 and the bottom plate magnet 300. After the microorganisms and sludge enter the mixing device, the magnetic field improves the physical properties of the sludge, making the sludge particles easier to aggregate and settle. This facilitates the full mixing and contact between the microorganisms and sludge, increases the growth rate and metabolic activity of microorganisms, and accelerates the biodegradation process of pollutants. The magnetic field-enhanced biological treatment can improve the overall effect of wastewater treatment and achieve the goal of cleaner and more efficient wastewater treatment.

[0027] A microbial inlet 430 is installed at the bend of the serpentine mixing main pipeline 400. The outlet end of the microbial inlet auxiliary pipeline 500 is connected to the microbial inlet 430. A pressure port 170 is installed on the feed gate plate 130, and the pressure port 170 is connected to the feed end of the microbial inlet auxiliary pipeline 500. The microbial inlet 430 is located at the bend of the serpentine mixing main pipeline 400, and its main function is to supplement the microbial inoculum during the mixing process. At the same time, since the bend is a critical area in fluid dynamics, uneven mixing and flow blockage are prone to occur here. The design of the microbial inlet 430 helps to solve the above problems. Microbial inoculum is injected into the fluid in the serpentine mixing main pipeline 400 through the microbial inlet auxiliary pipeline 500. The pressure port 170 is located on the feed gate plate 130 and is used to connect to an external pressure system to pressurize the microbial inlet auxiliary pipeline 500, ensuring that the microbial inoculum can be effectively injected into the serpentine mixing main pipeline 400.

[0028] When sludge enters the serpentine mixing main pipe 400 through sludge inlet 152, it flows along the serpentine pipe. At the bends of the serpentine pipe, uneven mixing and flow blockage may occur due to the inertia of the fluid. An external pressurization system connected through pressurization port 170 can pressurize the bacterial inoculum injection auxiliary pipe 500, allowing the bacteria to be injected through injection valve port 430 into the bends of the serpentine mixing main pipe 400. Injection valve port 430 forms multiple inlets; this design ensures that the bacteria are evenly distributed at the bends, thereby improving the mixing effect and preventing flow blockage. In this way, the bacteria and sludge are more thoroughly mixed under the influence of the magnetic field, improving the efficiency and effectiveness of biological treatment.

[0029] The serpentine mixing main pipeline 400 includes a straight pipeline 410 and an arc-shaped pipeline 420. The combination of the straight pipeline 410 and the arc-shaped pipeline 420 forms a serpentine layout, with the arc-shaped pipeline 420 located at the bends of the serpentine mixing main pipeline 400. Adjacent straight pipelines 410 are connected by arc-shaped pipelines 420. Both the straight pipeline 410 and the arc-shaped pipeline 420 are internally threaded pipes. The internally threaded design enhances fluid turbulence within the pipeline, thereby improving the mixing efficiency of bacteria and sludge.

[0030] There is a certain angle between two adjacent straight pipes 410, with an angle of 5°-10°. The angle design helps guide the fluid to flow smoothly in the pipe, helps prevent sludge from depositing at the bottom of the pipe, reduces fluid stagnation and dead zones, thereby improving the overall flow efficiency.

[0031] Both the feed gate 130 and the discharge gate 140 are equipped with handles 700. The design of the handles 700 makes it easier for operators to open or close the feed gate 130 and the discharge gate 140, which helps in the regular maintenance, inspection or cleaning of the equipment.

[0032] The pipe support 910, hanger 920, and clamp 930 together constitute a system for supporting and securing the serpentine mixing main pipe 400 and the bacterial injection auxiliary pipe 500. The pipe support 910 is housed within the outer casing 100. The top of the hanger 920 is hinged to the pipe support 910 to accommodate expansion and contraction of the pipe due to temperature changes or other factors. The bottom of the hanger 920 is fitted with a clamp 930, which is bolted to the serpentine mixing main pipe 400 and the bacterial injection auxiliary pipe 500, ensuring that the pipes do not slide or shift on the support.

[0033] The mixing device also includes a feed valve 110 and a discharge valve 120, both of which are electric ball valves to prevent backflow of liquid in the feed pipeline and maintain the working pressure during feeding, thereby improving overall stability. The feed valve 110 is located at the feed end of the serpentine mixing main pipeline 400, and the discharge valve 120 is located at the discharge end of the serpentine mixing main pipeline 400.

[0034] The control panel 800 is located on the feed gate plate 130. The control panel 800 controls the opening and closing of the feed valve 110 and the discharge valve 120, and also displays the internal pressure of the serpentine mixing main pipeline 400. The pressure sensor 600 is located inside the serpentine mixing main pipeline 400 to monitor the internal pressure in real time. The pressure sensor 600 is connected to the data input terminal of the controller, and the feed valve 110 and the discharge valve 120 are connected to the control output terminal of the controller.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
