Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a disturbance-type wastewater treatment device based on microbial inoculant treatment. Background Technology

[0002] In existing technologies, wastewater treatment using microbial agents is a highly efficient and environmentally friendly biological treatment method. Its core lies in providing sufficient oxygen and nutrients for microbial metabolic activities and ensuring that the agents and organic pollutants in the wastewater achieve full contact and reaction. However, in existing microbial wastewater treatment ponds, the concentrated oxygenation area leads to the aggregation of microbial communities. Wastewater with low oxygen content has little microbial aggregation, and the microorganisms and wastewater cannot be fully mixed and contacted, thereby reducing the treatment effect of the microbial community on the wastewater.

[0003] CN220520302U discloses an instrument for treating black and odorous water bodies using microbial agents. It includes a protective shell, an inlet pipe fixed to the upper end of the shell, an outlet pipe fixed to the right end of the shell, a water valve on the outlet pipe, a vertically distributed frame and filter plate fixed inside the shell, a motor fixed to the upper surface of the frame, a fixed cylinder fixed between the frame and the filter plate, a power rod connected to the lower end of the motor, threaded blades fixed to the outer circumference of the power rod, both the power rod and the threaded blades located inside the fixed cylinder, and circumferentially evenly distributed, vertically distributed openings on the outer circumference of the fixed cylinder. The spacing between the openings gradually increases. In this invention, the openings are distributed vertically to maintain a consistent flow rate of oxygenated wastewater at different vertical positions, thus maintaining a consistent oxygen content in the vertical direction. However, this technology only disperses the wastewater as it falls, while using a threaded rod in the middle to deliver oxygen for uniform dispersion. The oxygen diffuses from the middle outwards, and there is no stirring component inside the tank. This makes it difficult to effectively treat the wastewater near the inner wall of the tank, and the wastewater will directly pass through the filter plate after falling, resulting in poor treatment effect.

[0004] Based on this, a disturbance-type wastewater treatment device based on microbial inoculant treatment is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a disturbance-type wastewater treatment device based on microbial inoculant treatment to solve the problems in the background art.

Several connecting rods are fixedly connected to the middle of the growth frame. A disturbance component is disposed at the middle of the upper end of the growth frame. The disturbance component includes a submersible motor, which is fixedly connected to the middle of the upper end of the growth frame. A main rod is rotatably disposed in the middle of the growth frame and is driven by the submersible motor. A hyperboloid vertical shaft stirring disc is fixedly connected to the lower end of the main rod. The upper surface of the hyperboloid vertical shaft stirring disc is curved and has several disturbance strips fixedly connected in an array.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the upper end of the submersible motor is provided with a material distribution head, the upper end of which is conical and located directly below the lower end of the water inlet pipe.

[0008] In one alternative: each of the disturbance strips is a circular arc strip in the same direction.

Several oxygen delivery ports are fixedly connected in an array on the upper surface of the oxygen delivery disc. The upper surface of the oxygen delivery disc is fixedly connected to the lower surface of the processing box. The upper ends of the oxygen delivery ports are all disposed through the bottom of the processing box.

[0010] In one alternative embodiment: the microbial agent dispensing component includes a microbial agent storage box, which is fixedly connected to one side of the upper surface of the treatment box.

The unique hyperboloid vertical shaft stirring disc, combined with unidirectional arc-shaped disturbance strips, generates a gentle and multi-dimensional flow field driven by a submersible motor. This achieves efficient and uniform mixing of wastewater, oxygen, and microbial agents, completely eliminating dead zones and sludge deposition within the reactor, significantly improving mass transfer efficiency and pollutant degradation rates. Compared to traditional methods relying solely on aeration and stirring, this mechanical disturbance mode provides gentler shear force, avoiding damage to microbial flocs and maintaining high agent activity, effectively improving wastewater treatment efficiency and stability.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-6 As shown, a disturbance-type wastewater treatment device based on microbial agent treatment includes a treatment tank 1. The upper surface of the treatment tank 1 is provided with an agent dispensing component, the lower surface of the treatment tank 1 is provided with an oxygen supply component, and the inside of the treatment tank 1 is provided with a stirring component. The stirring assembly includes a growth frame 12, which is disposed inside the processing tank 1. Several connecting rods 13 are fixedly connected to the middle of the growth frame 12. A disturbance component is disposed at the middle of the upper end of the growth frame 12. The disturbance component includes a submersible motor 15, which is fixedly connected to the middle of the upper end of the growth frame 12. A main rod 16 is rotatably disposed in the middle of the growth frame 12 and is driven by the submersible motor 15. A hyperboloid vertical shaft stirring plate 17 is fixedly connected to the lower end of the main rod 16. The upper surface of the hyperboloid vertical shaft stirring plate 17 is curved and has several disturbance strips 18 fixedly connected in an array. In this embodiment, the growth frame 12 is fixed inside the treatment tank 1 by multiple connecting rods 13, providing a carrier for microbial attachment and growth. The disturbance component is driven by a submersible motor 15 to rotate the main rod 16. The hyperboloid vertical shaft stirring plate 17 at the bottom of the main rod 16 and the multiple arc-shaped disturbance strips 18 on its upper surface can generate a multi-dimensional three-dimensional flow state when rotating, producing water flow shearing and agitation, effectively breaking the stratification of sewage and bacterial agent, promoting full mixing of the two, avoiding the formation of local dead zones, and significantly improving reaction efficiency.

[0024] In one embodiment, such as Figure 1 As shown, a distribution head 14 is provided on the upper end of the submersible motor 15. The upper end of the distribution head 14 is conical and located directly below the lower end of the water inlet pipe 3. The distribution head 14 is installed on the upper end of the submersible motor 15, with its conical structure facing the lower part of the water inlet pipe 3. When sewage flows in, the distribution head 14 can disperse and guide the water flow, avoiding direct impact of the inlet water on the growth frame 12 or the stirring flow field, so that the sewage enters the reaction zone more smoothly, creating good initial conditions for subsequent uniform mixing.

[0025] In one embodiment, such as Figure 1 As shown, each of the disturbance strips 18 is a circular arc strip in the same direction, and each disturbance strip 18 is designed as a circular arc structure that bends in the same direction. When the hyperboloid vertical shaft stirring disk 17 rotates, these disturbance strips 18 with the same curvature and direction can work together to generate directional and consistent fluid shear force and lift, forming a stable and controllable axial and radial circulating flow field, thereby achieving efficient and low-consumption energy transfer and mixing.

[0026] In one embodiment, such as Figure 1As shown, the oxygen delivery assembly includes an oxygen delivery unit 9, which is located at the lower end of the treatment chamber 1. An oxygen delivery disk 10 is fixedly connected to the output end of the oxygen delivery unit 9. A plurality of oxygen delivery ports 11 are fixedly arrayed on the upper surface of the oxygen delivery disk 10. The upper surface of the oxygen delivery disk 10 is fixedly connected to the lower surface of the treatment chamber 1. The upper ends of all oxygen delivery ports 11 extend through the bottom of the treatment chamber 1. The oxygen delivery assembly is responsible for providing dissolved oxygen to the system. The oxygen delivery unit 9 pumps air into the oxygen delivery disk 10, and the multiple oxygen delivery ports 11 evenly distributed on the upper surface of the oxygen delivery disk 10 release air as microbubbles to the bottom of the treatment chamber 1. This uniform oxygen distribution method ensures that oxygen is evenly distributed throughout the reaction area, meeting the metabolic needs of aerobic microorganisms and supporting their efficient degradation of pollutants.

[0027] In one embodiment, such as Figure 1 As shown, the microbial agent dispensing assembly includes a microbial agent storage tank 6, which is fixedly connected to one side of the upper surface of the treatment tank 1. A dispenser 8 is provided on both sides of the microbial agent storage tank 6 and is fixedly connected to the input end of the dispenser 8 via a delivery pipe 7. The microbial agent dispensing assembly is used for quantitatively adding microbial agents. The microbial agent storage tank 6 stores liquid or solid microbial agents, and the agents are delivered to the dispensers 8 on both sides via the delivery pipe 7. The dispensers 8 evenly inject the microbial agents into the treatment tank 1, avoiding the inconvenience of manual dispensing and the potential for uneven distribution, thus achieving automated and precise dispensing of the microbial agents.

[0028] In one embodiment, such as Figure 1 As shown, each dispenser 8 is equipped with several output ends, all of which are arranged around the upper perimeter of the treatment tank 1. Each dispenser 8 has multiple output ends, which are distributed around the upper perimeter of the inner wall of the treatment tank 1. Through this multi-point distribution dosing method, the microbial agent can enter the water body evenly from different positions, effectively preventing the agent from rapidly settling or accumulating near the dosing point due to single-point dosing, and ensuring the rapid dispersion of the agent in the reaction space.

[0029] In one embodiment, such as Figure 1 As shown, the upper end of the treatment tank 1 is equipped with a water inlet pipe 3, and the lower end of the treatment tank 1 is fixedly connected to a water outlet pipe 4. A solenoid valve 5 is fixedly connected to the upper end of the water outlet pipe 4. The water inlet pipe 3 is used to introduce the wastewater to be treated into the upper part of the treatment tank 1. After treatment, the purified water is discharged through the water outlet pipe 4 located at the lower end of the tank. The solenoid valve 5 installed on the water outlet pipe 4 is controlled by the controller 2 to open and close, realizing continuous water intake and controllable drainage during the treatment process, facilitating automated operation and management.

[0030] In one embodiment, such as Figure 1As shown, a controller 2 is installed on one side of the treatment tank 1. The controller 2 is electrically connected to the bacterial agent dosing component, the oxygen supply component, the stirring component, and the solenoid valve 5. The controller 2 serves as the control center of the equipment and is electrically connected to all electric components, including the bacterial agent dosing component, the oxygenator 9, the submersible motor 15, and the solenoid valve 5. Through a preset program, the controller 2 can coordinate the orderly operation of each component, such as timed addition of bacterial agent, adjustment of aeration rate according to water quality, and control of stirring intensity, thus achieving controllable control of the entire wastewater treatment process.

[0031] The above embodiment discloses a disturbance-type wastewater treatment device based on microbial agent treatment. The wastewater to be treated is introduced into the upper part of the treatment tank 1 via the inlet pipe 3. The agent dispensing component evenly sprays the microbial agent into the upper space of the tank through the agent storage tank 6, the delivery pipe 7, and multiple dispensers 8. The oxygen supply component located at the bottom of the device delivers air to the oxygen supply plate 10 via the oxygenator 9, and releases it in the form of microbubbles through the evenly distributed oxygen outlets 11, providing sufficient dissolved oxygen for microbial metabolism. The core stirring component of the device begins operation. The submersible motor 15 drives the main rod 16 to rotate, causing the hyperboloid vertical shaft stirring plate 17 at its lower end and the arc-shaped disturbance strips 18 arranged in the same direction on the plate to rotate. This unique mechanical structure generates a gentle and multi-dimensional three-dimensional flow field, which on the one hand promotes thorough mixing and contact between wastewater, agent, and oxygen, greatly improving mass transfer efficiency; on the other hand, the uniform disturbance effectively breaks up water stratification, eliminates reaction dead zones, and prevents sludge deposition. Meanwhile, the growth frame 12, placed in the water, provides a carrier for microorganisms to attach and grow via connecting rods 13, which helps maintain a high biomass. The entire treatment process is coordinated and controlled by controller 2 to achieve automated and intelligent operation. Finally, the treated water that meets the standards is discharged from the bottom outlet pipe 4 via solenoid valve 5.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application 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 application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
