Description

Technical Field

[0001] This utility model relates to the field of aeration technology for activated sludge tanks in aerobic wastewater treatment processes, specifically to a detachable aeration device. Background Technology

[0002] Currently, our company uses an anaerobic-aerobic biological treatment process for wastewater treatment in activated sludge tanks. The aerobic stage utilizes activated sludge treatment; therefore, increasing the aeration rate to provide sufficient dissolved oxygen for the microorganisms is crucial during the aerobic process. Existing aeration equipment such as… Figure 3 The device consists of an ABS pipe connected to a compressed air interface, a main pipe located on one side of the tank bottom, multiple horizontally distributed branch pipes on the tank bottom, and several aeration hoses on the branch pipes. The aeration hoses are set at a 45-degree angle. The entire pipe frame is fixed to the bottom of the aeration tank. The aeration hoses are made of PVC material and have numerous uniform micropores. During operation, compressed air is delivered to the main pipe through the ABS pipe, then distributed to the branch pipes, and finally discharged through the micropores on the aeration hoses to achieve aeration. However, the existing structure has several problems: 1. Uneven aeration occurs when the micropores on the aeration hoses become clogged, and replacing the branch pipes is difficult; 2. The aeration range is limited to a certain area around the branch pipes, resulting in a small aeration range. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a detachable aeration device that can solve the problems of easy clogging of micropores in existing aeration devices and the difficulty in replacement and cleaning after clogging.

[0004] To solve the aforementioned technical problems, this application adopts the following technical solution:

[0005] A detachable aeration device includes an air inlet main pipe located at the upper end of an activated sludge tank, several branch pipes vertically located below the air inlet main pipe, and an aeration pipe located at the lower end of the branch pipes, wherein the aeration pipe is provided with aeration micropores.

[0006] Preferably, a plurality of branch pipes are provided on the lower side of the main intake pipe, and the branch pipes are provided on the branch pipes. The branch pipes and the branch pipes are connected by flanges.

[0007] Preferably, a control valve is provided between the branch pipe and the diversion pipe.

[0008] Preferably, the aeration pipe includes a connector, a support core tube disposed on both sides of the connector, and a latex sleeve sleeved outside the support core tube. The aeration micropores are disposed on the latex sleeve and are in a closed state when not aerated.

[0009] Preferably, the diverter has symmetrical air outlets on both sides, and the connector adopts a semi-circular clamp structure. The two aeration pipes are clamped and fixed on both sides of the diverter through the connector.

[0010] Preferably, the diversion pipe is provided with two sets of air outlets arranged in a cross pattern, and the two sets of aeration pipes are arranged in a cross pattern on the diversion pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This device provides ample dissolved oxygen for microbial oxidation and decomposition of organic matter. Simultaneously, the compressed air injection process keeps the activated sludge in suspension, increasing the contact area between microorganisms and organic matter, thereby accelerating the decomposition process and improving degradation efficiency. Because the aeration pipes are located on the activated sludge, they are less prone to clogging. The orderly arrangement of each aeration pipe ensures uniform dissolved oxygen distribution in the activated sludge tank, facilitating better organic matter degradation. Furthermore, it is durable, has a long service life, and saves on air consumption and energy. Attached Figure Description

[0017] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0020] like Figure 1 As shown, a detachable aeration device includes an air inlet main pipe 6 located at the upper end of the activated sludge tank 3, several branch pipes 4 vertically located below the air inlet main pipe 6, and an aeration pipe 1 located at the lower end of the branch pipes 4. The aeration pipe 1 is provided with aeration micropores 2.

[0021] The existing aeration device in activated sludge tank 3 was replaced. In the new aeration device, the compressed air inlet main 6 is located above activated sludge tank 3, while the aeration pipe 1 extends into activated sludge tank 3 suspended through several branch pipes 4 at a certain distance from the bottom of activated sludge tank 3, thus keeping the aeration pipe 1 in a suspended state. When compressed air enters from the inlet main 6, it is distributed to the aeration pipe 1 through the branch pipes 4, and then oxygenates the wastewater in activated sludge tank 3 through aeration micropores 2, thereby providing sufficient and uniform dissolved oxygen for the microorganisms in the aeration tank to oxidize and decompose organic matter. This device provides sufficient dissolved oxygen for the microorganisms to oxidize and decompose organic matter. At the same time, during the process of blowing in compressed air, the activated sludge is kept in a suspended state, increasing the contact area between microorganisms and organic matter, thereby accelerating the decomposition process of pollutants and improving degradation efficiency. Because the aeration pipe 1 is located on the activated sludge, the aeration pipe 1 is not easily clogged.

[0022] A further improvement is that a plurality of branch pipes 7 are provided on the lower side of the main intake pipe 6, and the branch pipe 4 is provided on the branch pipe 7. The branch pipe 4 and the branch pipe 7 are connected by a flange.

[0023] The diversion pipe 7 can adopt a three-way pipe structure, with each three-way pipe connected in series by straight pipes. One end of the straight pipe is sealed with a cap, resulting in a simple overall structure. The entire air intake main pipe 6 can be made of materials such as ABS / PP / PCV or steel pipe structure, forming the diversion pipe 7 by opening holes and welding. The branch pipes 4 and the diversion pipes 7 are connected by flanges, allowing each branch pipe 4 and the aeration pipe 1 installed on the branch pipe 4 to be an independent device. Therefore, if a problem occurs with the aeration pipe 1 on a branch pipe 4 during use, it can be disassembled, replaced, and repaired independently in a timely manner. The operation is simpler and more convenient during maintenance and replacement, and operators no longer need to waterproof or enter the pool to operate, especially in winter, resulting in a better operating environment.

[0024] A further improvement is made by providing a control valve 5 between the branch pipe 4 and the diversion pipe 7.

[0025] When it is necessary to disassemble a branch pipe 4, simply close the corresponding control valve 5 to cut off the airflow. The replacement will not affect the operation of other aeration pipes 1 in the entire device.

[0026] Further improvements include, for example Figure 2 As shown, the aeration pipe 1 includes a connector 11, a support core tube 12 disposed on both sides of the connector 11, and a latex sleeve 13 sleeved outside the support core tube 12. The aeration micropores 2 are disposed on the latex sleeve 13, and the aeration micropores 2 are in a closed state when not aerated.

[0027] Aeration pipe 1 is connected to branch pipe 4 via connector 11. Gas in branch pipe 4 can enter between support core pipe 12 and latex sleeve 13 through the hole in connector 11, and finally aerate outward through aeration micropores 2. Aeration micropores 2 are latex micropores, which are closed in the non-aeration state. When compressed air is injected, the latex micropores can expand and contract with the air pressure, and evenly release air, providing sufficient and uniform dissolved oxygen for microorganisms in the aeration tank to oxidize and decompose organic matter. One end of latex sleeve 13 can be fastened to connector 11 with a clamp. When latex sleeve 13 is damaged, it can be replaced independently, reducing costs.

[0028] A further improvement is made in that an air outlet 8 is symmetrically provided on both sides of the diversion pipe 7, and the connector 11 adopts a semi-circular clamp structure. The two aeration pipes 1 are clamped and fixed on both sides of the diversion pipe 7 through the connector 11.

[0029] The connector 11 adopts a semi-circular clamp structure. The connectors 11 of the two aeration pipes 1 are combined to form an annular clamp. An air outlet 8 is symmetrically provided on both sides of the diversion pipe 7. After the two aeration pipes 1 are installed through the connector 11, it ensures that the connector 11 is clamped and fixed on both sides of the diversion pipe 7, while improving the efficiency of horizontal aeration. When only one direction of aeration is needed, the structure of two aeration pipes 1 connected by a flange can also be used.

[0030] A further improvement is that the diversion pipe 7 is provided with two sets of air outlet holes 8 arranged in a cross pattern, and the two sets of aeration pipes 1 are arranged in a cross pattern on the diversion pipe 7.

[0031] Two aeration structures, each consisting of two aeration pipes 1, are installed on the diversion pipe 7. The two sets of aeration pipes 1 are arranged in a cross-shaped structure on the diversion pipe 7. When compressed air enters the activated sludge tank 3 through the cross aeration pipe 1, the aeration area is larger, which better increases the contact area between microorganisms and organic matter, thereby accelerating the decomposition process of pollutants and improving the degradation efficiency.

[0032] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
