Description

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. It utilizes physical, chemical, and biological methods to treat wastewater, purify it, reduce pollution, and ultimately achieve wastewater recycling and reuse, making full use of water resources. Wastewater treatment requires aeration, necessitating the use of aeration devices. These devices force air into the wastewater, allowing it to come into contact with air and become oxygenated. This enhances the contact between organic matter, microorganisms, and dissolved oxygen, thereby oxidizing and decomposing the organic matter in the wastewater.

[0003] While traditional aeration devices possess aeration capabilities, they also have some shortcomings. For example, their installation structure is relatively fixed, making it difficult to disassemble and replace them when damaged, which affects the aeration effect and causes inconvenience for subsequent maintenance. In addition, their mixing ability is poor, making it difficult to ensure sufficient oxygen diffusion and adequate contact between wastewater and oxygen, thus compromising the wastewater treatment effect. Therefore, to address the above problems, a high-efficiency intelligent aeration device for wastewater treatment is proposed. Utility Model Content

[0025] A high-efficiency intelligent aeration device for wastewater treatment includes an aeration tank 1. An inlet pipe 2 is connected to the top of one side wall of the aeration tank 1, and an outlet pipe 3 is connected to the bottom of the other side wall of the aeration tank 1. An aeration main pipe 4 is provided at the bottom of the inner cavity of the aeration tank 1.

An installation assembly 7 is provided between the aeration branch pipes 5 and the aerator 6. Several modular carrier biofilm reactors 8 are provided in the inner cavity of the aeration tank 1. A stirring assembly 9 is provided below the modular carrier biofilm reactors 8.

[0026] Mounting assembly 7 includes a first mounting plate 701 fixedly connected to the top of the aeration branch pipe 5 and a second mounting plate 702 fixedly connected to the bottom of the aerator 6. The second mounting plate 702 has symmetrically arranged hinges 703 at its left and right ends, with fastening clips 704 hinged to the hinges 703. The first mounting plate 701 has symmetrically arranged and fixedly connected fastening brackets 705 at its left and right ends. The fastening clips 704 and fastening brackets 705 are positioned correspondingly and matched in specifications. Mounting bolts 706 symmetrically penetrate the bottom sides of the first mounting plate 701. The second mounting plate 702... The mounting assembly 7 has symmetrically arranged mounting screw holes 707 corresponding to the positions and specifications of the mounting bolts 706. The mounting assembly 7 provides good installation capability between the aeration branch pipe 5 and the aerator 6, thus ensuring the structural stability of the aerator 6 during normal use and allowing for disassembly and replacement in case of damage, without affecting the aeration effect or causing inconvenience for later maintenance. The mixing assembly 9 includes a drive motor 901, with a transmission shaft 902 fixedly connected to the output end of the drive motor 901. A transmission bracket 903 is fixedly connected to the bottom of component 2. Several stirring support plates 904 are arranged longitudinally at equal intervals between the transmission brackets 903, and several pressure-reducing through holes 905 are arranged at equal intervals on the stirring support plates 904. Connecting blocks 906 are symmetrically and fixedly connected to both ends of the stirring support plates 904. Connecting slots 907, equal in number, corresponding in position, and matching in specifications to the connecting blocks 906, are symmetrically opened longitudinally on the inner sidewall of the transmission bracket 903. A positioning block 908 is fixedly connected to the center of the rear wall of the connecting block 906. The rear of the connecting slot 907... The wall has a positioning slot 909 that corresponds to the position of the positioning block 908 and matches its specifications.

The outer wall of the transmission bracket 903 has a number of connecting bolts 911 that are equal in number, position and specifications to the connecting screw holes 910. The mixing component 9 can provide good mixing ability, so it can fully diffuse oxygen and fully contact sewage with oxygen, thereby ensuring the sewage treatment effect.

[0027] Workflow: First, power on all electrical appliances and connect them to external controllers. Aeration tank 1 provides treatment space for wastewater. Inlet pipe 2 introduces wastewater into aeration tank 1, and outlet pipe 3 discharges the aerated wastewater from aeration tank 1 for further treatment. Main aeration pipe 4 and branch aeration pipes 5 can transport gas via external equipment. Aerators 6 disperse air into fine bubbles, distributing them evenly in the wastewater to improve oxygen transfer efficiency. Installation assembly 7 provides good installation capability between branch aeration pipes 5 and aerators 6, ensuring the structural stability of aerators 6 during normal use and allowing for disassembly and replacement in case of damage. It will not affect the aeration effect or cause inconvenience to later maintenance. When installing aerator 6, first place it on top of the aeration branch pipe 5, aligning the first mounting plate 701 with the second mounting plate 702 and aligning the fastening buckle 704 with the fastening seat 705. Then, use the hinge 703 to rotate the fastening buckle 704 to the fastening seat 705 for engagement, providing good connection strength and positioning capability between the first mounting plate 701 and the second mounting plate 702. At this point, the mounting bolt 706 corresponds to the mounting screw hole 707. Finally, screw the mounting bolt 706 into the mounting screw hole 707. Disassembly is similar. The modular carrier biofilm reactor 8 can combine suspended activated sludge and attached biofilm. The modular carrier biofilm reactor 8 is filled with fabric fiber packing material. This material has excellent biocompatibility and a large specific surface area, providing an ideal environment for biofilm attachment and growth. Over time, the biofilm on the packing material gradually grows and thickens, thus purifying the water. Combined with the aeration treatment of aerator 6, it provides an ideal oxygen supply to the biofilm. Furthermore, the vertical flow caused by air diffusion, along with the flexible oscillation of the carrier, continuously removes aging biofilm and automatically adjusts its thickness. The air mixing intensity provided by aerator 6 is sufficient to peel off aging biofilm, thereby maintaining biofilm permeability and healthy growth without requiring additional energy consumption to mix the biofilm or avoid carrier interference. The mixing assembly 9's drive motor 901, via transmission shaft 902, drives transmission bracket 903 to rotate, which in turn drives mixing support plate 904 to rotate synchronously, providing excellent mixing capability. This ensures sufficient oxygen diffusion and contact between wastewater and oxygen, guaranteeing effective wastewater treatment. The pressure-reducing through-hole 905 reduces water pressure resistance during rotation of mixing support plate 904. Furthermore, the detachable structure between mixing support plate 904 and transmission bracket 903 eliminates the need for complete replacement of the entire mixing support plate; only the damaged plate needs to be disassembled and replaced.Therefore, it can reduce the difficulty and cost of later maintenance. During installation, the connecting blocks 906 at both ends of the mixing support plate 904 are first inserted into the connecting slots 907 on the transmission bracket 903 for positioning. When the connecting blocks 906 are fully inserted into the connecting slots 907, the positioning blocks 908 on the rear wall will insert into the positioning slots 909 for positioning and engagement, thus providing good positioning capability and connection strength between the connecting blocks 906 and the connecting slots 907. At this time, the positions of the connecting bolts 911 and the connecting screw holes 910 correspond. Finally, the connecting bolts 911 are screwed into the connecting screw holes 910. Disassembly is similar. Through the external control system, the inlet pipe 2, outlet pipe 3, aeration main pipe 4, aerator 6, and drive motor 901 can be controlled and adjusted to achieve intelligent control.
