Abstract
Description
Technical Field
[0001] The invention relates to the technical field of membrane bioreactors, and in particular to a modular and splicable MBR pulse aeration device. Background Art
[0002] Compared with traditional wastewater biological treatment processes, the membrane bioreactor (MBR) process has better effluent quality, can be directly reused, occupies a small area, has a high concentration of activated sludge, has a small amount of residual sludge, and is easy to achieve automatic control. As a result, it has been widely used and is becoming more and more mature. During the operation of the MBR, the key to solving membrane pollution is to aerate and shake the membrane fibers during the operation of the membrane fibers to remove pollutants adsorbed on the surface of the membrane fibers. The conventional way to remove pollutants is to aerate the bottom of the membrane fibers, and the air-water mixture flushes the membrane fibers from bottom to top. Different aeration structures have different effects on the removal of dirt.
[0003] Pulse aeration is the most advanced aeration structure and has been widely used in the MBR field in recent years. In actual water treatment projects, due to the different requirements for the specifications and dimensions of membrane tanks, membrane modules, and membrane components in different projects, the length and dimensions of the aeration device also need to change accordingly. However, the structure of the pulse aeration device is complex, resulting in the need to open new molds and re-make pulse aeration devices of different specifications, which in turn causes problems such as high cost, long cycle, and material waste.
[0004] Existing MBR membrane module pulse aeration device: The aeration device is an integrated structure with a fixed length and size. It can only be adapted to a single module, has a narrow application range, and has poor versatility. The aeration intensity is weak, and the cleaning effect of high-intensity pulse aeration on the membrane fibers cannot be achieved. In actual water treatment projects, due to different requirements for the specifications and sizes of membrane tanks, membrane modules, and membrane components in different projects, the length and size of the aeration device also need to change accordingly. However, the pulse aeration device has a complex structure, which means that pulse aeration devices of different specifications need to be newly molded and remade, which in turn causes problems such as high cost, long cycle, and material waste.

[0008] Furthermore, the outer shell is a split structure, each split is a module unit, and the outer shells are installed in sequence in a snap-fit form, and can be composed of multiple aeration units as required, and adjacent aeration units are relatively independent.
[0009] Furthermore, the gas supply groove is a split structure, and the gas supply groove is installed at the bottom of the outer shell, corresponding to the outer shell one by one. After multiple gas supply grooves are spliced, they are connected as a whole and are used to transmit gas.
[0010] Furthermore, the air distribution hood is rectangular and is installed on the top of the outer shell, corresponding to the outer shell one by one. The air distribution hood is provided with a plurality of air outlets to equally divide the airflow of the pulse aeration.

[0012] Furthermore, the overall length can be adjusted according to the aeration requirements of the membrane module, and is not limited to a fixed size. The device can be spliced from 2 to n modules to form a complete pulse aeration system.
[0013] Technical terms: (1) MBR (Membrane Bioreactor) is a wastewater treatment process that organically combines efficient membrane separation technology with traditional biological treatment technology; (2) Modularity is a method of decomposing a complex system into independent functional modules and achieving interaction and collaboration between modules through clearly defined interfaces; (3) Splicing refers to connecting multiple modules together in a specific way to achieve the target function; (4) Pulse aeration is to release gas into the water intermittently, making the aeration process change in a pulsed manner, rather than continuous and stable aeration like traditional aeration methods.

[0029] Those skilled in the art should understand that the drawings are merely schematic diagrams of embodiments, and the components in the drawings are not necessarily necessary for implementing the present invention.
[0030] Aiming at the shortcomings of the current existing MBR pulse aeration devices: ① The pulse aeration is an integrated structure with a fixed length. Each aeration structure can only be adapted to a single group, with a narrow application range and poor universal effect; ② The pulse aeration intensity is weak, and high-intensity pulse aeration cannot be achieved, which is inefficient and has poor cleaning effect on the membrane filaments. The modular and splicable MBR pulse aeration device provided by the present invention solves the problems of the single size and narrow application range of the pulse aeration box. On the basis of achieving efficient pulse aeration, the complex aeration device is decomposed into single modules that can be used in combination. The gas collecting shell and the air supply trough, which play a major role, adopt a split design, which can be spliced and lengthened according to project requirements to adapt to various forms of MBR groups. The modular and splicable MBR aeration device can adapt well to a variety of different environments and can be spliced and installed according to different application environments. The advantages of the present invention are as follows: ① The modular design decomposes the complex aeration device into individual modules that can be used in combination on the basis of achieving efficient pulse aeration. The gas collecting outer shell and the air supply tank that play a major role adopt a split design, which can be spliced and lengthened according to project requirements to be suitable for various forms of MBR components; ② The pulse aeration has high intensity, which can achieve efficient pulse aeration and has a better cleaning effect on the membrane fibers.
[0031] In a specific embodiment, a modular and splicable MBR pulse aeration device is provided, including an outer shell, an air supply tank, an air distribution hood, etc. The outer shell and the air supply tank are both split structures, and the left and right sides of the outer shell are respectively provided with parent-child buckles, and the outer shell can be spliced and installed in sequence, and a groove is left at the bottom of the outer shell, and the air supply tank and the outer shell are installed in the groove through buckles, and the air supply tank is located at the bottom of the outer shell and extends along the length direction of the outer shell, and an air supply tank air inlet pipe is provided at one end of the air supply tank, and the other end is a fixed end, and air supply tank air outlet holes are opened on both sides of the air supply tank, and the air distribution hood is installed on the top of the outer shell, and the air distribution hood is provided with a plurality of air outlets.
[0032] The outer shell is a split structure, each split is a module unit, and the outer shell is installed in sequence in the form of a buckle, which can form multiple aeration units as required, and adjacent aeration units are relatively independent. The air supply tank is a split structure, corresponding to the gas collection outer shell. The air supply tank is fixed under multiple aeration units in the form of a buckle. One end of the air supply tank is provided with an air supply tank air inlet, and the other end is a fixed end. The air inlet and the fixed end are both connected to the MBR membrane group.
[0033] This embodiment is mainly suitable for aeration of MBR membrane modules. The modular split design has a wide range of applications and can achieve efficient pulse aeration effects. The use of trough aeration forms to achieve pulse aeration effects in physical structure is more reasonable than conventional pulse aeration designs. On the one hand, the pulse aeration intensity is high, which can achieve the effect of small airflow supply and instant release of large airflow, thereby reducing aeration energy consumption; on the other hand, the modularly designed pulse aeration structure is suitable for a variety of scenarios and can be applied to a variety of MBR membrane modules.
[0034] The overall length of the pulse aeration device can be adjusted according to the aeration requirements of the membrane module, and is not limited to a fixed size. The device can be spliced from 2 to n modules to form a complete pulse aeration system. This embodiment takes 4 modules spliced together as an example to specifically introduce the modular pulse aeration structure.
[0035] like Figure 1 , Figure 2 As shown, the pulse aeration device provided in this embodiment includes an outer shell 1, an air cloth hood 2, an outer shell buckle mother component 3, an outer shell buckle subcomponent 4, an air supply slot 5, an air supply slot air inlet 6 and an air supply slot fixing frame 7. The main structure of the aeration device is composed of the outer shell 1, the air cloth hood 2, and the air supply slot 5. The aeration device can be composed of 2 to n outer shell modules to form 2 to n aeration units as an aeration whole (in this embodiment, 4 outer shell modules are used to form 4 aeration units as an aeration whole), each aeration unit is relatively independent, and an air cloth hood is installed above the outer shell of each unit, and an air supply slot is installed below the outer shell. During aeration, a constant flow of air enters from the air inlet 6 of the air supply tank. After the gas reaches the air supply tank 5, the gas is evenly distributed to the four aeration units. The gas will gradually fill the effective gas storage space in the outer shell, and at the same time press the liquid surface in the tank downward. When the gas fills the gas collecting shell, the gas in the shell will be instantly released through the air cover in the form of large bubbles. At the same time as the gas is released, water fills the tank again, and the gas is collected and released reciprocatingly, forming large bubble pulse aeration.
[0036] In summary, the modular pulse aeration device described in the embodiment of the present invention, on the basis of achieving efficient pulse aeration, decomposes this complex aeration device into individual modules that can be used in combination, wherein the gas collecting shell and the gas supply tank that play a major role adopt a split design, which can be spliced and lengthened according to project requirements to be suitable for various forms of MBR components. On the basis of maintaining the advantages of efficient pulse aeration, the modular splicable MBR aeration device can adapt well to a variety of different environments, and can be spliced and installed according to different application environments, with high adaptability.
[0037] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative work on the basis of the technical solution disclosed in the present invention should be included in the scope of protection of the present invention.
