Description

Technical Field

[0001] This disclosure relates to the field of environmental water treatment technology, and in particular to quick-installation aeration devices and membrane modules. Background Technology

[0002] Membrane bioreactor (MBR) technology is a novel and highly efficient wastewater treatment process that combines efficient membrane separation technology with the traditional activated sludge process. The MBR achieves efficient sludge-water separation through hollow fiber membranes. Simultaneously, due to its effective retention capacity, it can retain microorganisms with long generation cycles, achieving deep wastewater purification. Furthermore, nitrifying bacteria can proliferate fully within the system, resulting in significant nitrification and enabling advanced phosphorus and nitrogen removal.

[0003] In related technologies, MBR can be used in conjunction with an aerator to continuously flush the membrane fibers through the gas and liquid two-phase flow generated by aeration, thereby removing the sludge adsorbed on the surface of the membrane fibers.

[0036] Currently, some aerators have a one-piece structure, which is large in size and inconvenient to install during actual transportation and construction. Therefore, a modular assembly structure is needed. How to find an aerator structure that is easy to install and improves construction and installation efficiency has become a technical problem that urgently needs to be solved in the industry.

[0037] In view of this, the present disclosure provides an aeration device that achieves a simple and efficient structure for split assembly to form an aeration chamber and an air supply chamber, thereby solving the problems in the related art.

[0038] Please refer to the following: Figures 1 to 4 . Figure 1 A three-dimensional structural schematic diagram of the aeration device in the embodiments of this disclosure is shown. Figure 2 A three-dimensional structural diagram showing the separation of the aeration shell and the gas diversion component in an embodiment of this disclosure is provided.

[0039] The aeration device 100 includes an aeration shell 110, a partition structure 120, and an aeration component 130.

[0040] The aeration shell 110 forms a receiving space 1100 with a bottom opening 1101. As an example, the aeration shell 110 includes a top wall and peripheral sidewalls adhering to the edge of the top wall, with no bottom wall forming the opening 1101. The aeration shell 110 is exemplary implemented as a cuboid, having a length direction (X direction) and a width direction (Y direction). The shape of the aeration shell 110 can also vary depending on the layout of the aeration chamber 1103. The top of the aeration shell 110 forms an air inlet 111 communicating with the receiving space 1100 and a plurality of air outlets 112. In some embodiments, the air inlet 111 is located at one end along the length direction of the aeration shell 110. The air inlet 111 can be connected to an air source to allow air to enter the aeration shell 110. In some embodiments, the plurality of air outlets 112 can be linearly spaced along one extending direction of the aeration shell 110.

[0041] Optionally, in Figure 1 and Figure 2 In this system, each air outlet 112 is connected to a gas diverter 140. The gas diverter 140 is fixedly mounted on the outer top wall of the aeration shell 110. The gas diverter 140 has a central cavity communicating with the air outlet 112, and diversion ports extending laterally and evenly around the central cavity. Large air bubbles discharged from the air outlet 112 are broken into multiple smaller air bubbles by the gas diverter 140 and output through the diversion ports. These smaller air bubbles can uniformly scrub the membrane module within its coverage area and also agitate the nearby water, achieving the agitation effect of a sludge mixing pump.

[0042] It should be noted that the gas diversion device and its structure in the above embodiments are only examples and can be changed in actual scenarios. For example, the shape may be changed or the gas diversion and diffusion may not be required, and the diversion device may not be set. It is not limited to the embodiments.

[0043] Please see Figure 3 and Figure 4 The aeration device 100 includes a partition structure 120 disposed in the receiving space 1100, forming an air supply chamber 1102 between the partition structure 120 and the inner wall of the aeration shell 110, and surrounding at least one aeration chamber 1103. As an optional example, Figure 3The air supply chamber can be annular and continuous, and at least one aeration chamber 1103 can include multiple aeration chambers 1103 spaced apart from each other. The partition structure 120 forms a ventilation structure connecting the air supply chamber and the aeration chamber. As an example, the partition structure 120 can form ventilation structures 160 connecting the air supply chamber 1102 and each aeration chamber 1103 at at least two predetermined height positions on opposite sides. By having annular and continuous air supply chambers 1102 surrounding the multiple aeration chambers 1103, communication between the aeration chamber 1103 and the air supply chamber 1102 can be formed on at least two sides of each aeration chamber 1103, so that the air supply chamber 1102 can uniformly supply air to each aeration chamber 1103. Preferably, the air inlet 111 can also be connected to an air storage tank (not shown) at the far end of the air source. The air storage tank can store or supply air according to the internal and external pressure difference, which also helps to balance the air distribution between each aeration chamber 1103, thereby helping to improve the uniformity of air volume between each aeration chamber 1103. This ensures that the air volume in each aeration chamber 1103 changes uniformly during pulse aeration, and the aeration frequency can also remain consistent. As a result, the wiping of different parts of the membrane fibers is also very uniform, effectively avoiding the problem of flux reduction or even attenuation caused by different cleanliness of membrane fibers in different parts.

[0044] The aeration chamber 1103 and the air outlet 112 (see...) Figure 2 (Set in pairs) Figure 2 The example shows four air vents 112. Figure 4 The image shows an aeration chamber 1103 corresponding to each air outlet 112. Each aeration chamber 1103 is equipped with an aeration component 130, which connects to the corresponding air outlet 112. Optionally, the plurality of air outlets 112 can be arranged at equal intervals. Each aeration chamber 1103 can be coaxially arranged with the corresponding air outlet 112. The plurality of aeration chambers 1103 have the same dimensions, thus having the same capacity for uniform air output.

[0045] It should be noted that in other embodiments, the number and structure of the aeration chambers 1103 may also be varied, and are not limited to the illustrated example.

[0046] like Figure 4 As shown, multiple aeration components 130 are respectively disposed in each aeration chamber 1103 for connecting the paired aeration chambers 1103 and the air outlet 112.

[0047] Please see Figure 4 , Figure 5 , Figure 6 and Figure 7 The diagram illustrates an embodiment of the partition structure 120. Figure 5 A side view of the aeration device in an embodiment of this disclosure is shown. Figure 6exhibit Figure 5 A cross-sectional view of the aeration device along the FF direction. Figure 7 A schematic diagram showing the exploded structure of the partitioned structure.

[0048] The partition structure 120 includes a set of first partitions 121 and a set of second partitions 122. The first partitions 121 and the second partitions 122 can be overlapped to separate the aeration chamber 1103 and the air supply chamber 1102, which is simple to assemble, highly efficient, and reliable.

[0049] A set of first partitions 121 are arranged along the length of the aeration shell 110 in the direction of the receiving space, for example, arranged parallel to each other along the length of the aeration shell 110 to separate the areas where the linearly arranged aeration chambers 1103 are located. The first partitions 121 are engaged with at least the top wall of the aeration shell 110. As an example, the top edge of the set of first partitions 121 is connected to the top wall of the aeration shell 110. The first partitions 121 form clearance gaps between their opposite side edges in the width direction and their facing inner sidewalls. As an example, the side edges of the first partitions 121 adjacent to the top edge can also be connected to the opposite inner sidewalls of the aeration shell 110 (they can be joined or integrally connected). Optionally, from Figure 4 and Figure 7 As can be seen, the first partition 121 forms a continuous and sealed connection with the inner top wall and the inner side walls of the aeration shell 110, so that air / water cannot be exchanged between the air supply chamber 1102 and the aeration chamber 1103 (and between the aeration chamber 1103) at the continuous and sealed connection, thus restricting the gas transport between the air supply chamber 1102 and the aeration chamber 1103 through the ventilation structure 160.

[0050] Of course, in other embodiments, the number and arrangement of the aeration chambers 1103 can be varied. For example, if the number of aeration chambers 1103 is reduced, the number of first partitions 121 will also be reduced accordingly.

[0051] In a set of first partitions 121, the first and last two partitions 121 at the beginning and end positions in the arrangement direction respectively form gaps with the inner walls of the corresponding two aeration shells 110. Meanwhile, the opposite side edges 1211 of the end of the first partition 121 furthest from the top wall of the aeration shell 110 also form gaps with the inner walls of the other two aeration shells 110. Thus, the two gaps are connected, forming a continuous annular (or partially annular) gap, as... Figure 4 As shown, after connecting a set of the second partitions 122, the annular continuous air supply chamber 1102 can be formed in the annular continuous gap.

[0052] Optionally, the first partition plate 121 may be provided with a reinforcing structure, and the reinforcing structure includes at least one reinforcing portion. The reinforcing portion 1212 may be implemented as a reinforcing rib or the like. As an example, at least one reinforcing portion 1212 is provided on each of the first partition plates 121. As an example, a plurality of reinforcing portions 1212 arranged at intervals in the width direction are provided on each of the first partition plates 121. For example, one or more reinforcing ribs connecting the first partition plate 121 and the inner top wall of the aeration shell 110 / the inner side wall of the aeration shell 110, etc.

[0053] A group of the second partition plates 122 are in surrounding connection and matching with the group of the first partition plates 121, so as to form each of the aeration chambers 1103 on a side (i.e., the inner side) facing away from the gap. In Figure 4 and Figure 7 , the first partition plates 121 are arranged at intervals along a straight line, and open sides are formed on opposite sides of the first partition plates in the arrangement direction. There may be two second partition plates 122, which are respectively fixedly connected with the side edges 1211 of the first partition plates 121 on the same side at the two sides to form a surrounding connection to fill the open sides and enclose each of the aeration chambers 1103. It can be understood that in other examples, since the arrangement mode of the first partition plates 121 changes based on the required arrangement mode of the aeration chambers 1103, the number and size of each second partition plate 122 and the number of connected first partition plates 121 can all be changed. For example, for a plurality of aeration chambers 1103 arranged in a "field" shape, the middle "ten" may be formed by the first partition plates 121, and the outer "mouth" may be formed by the second partition plates 122. Therefore, the embodiment of the partition structure 120 in the drawings of the present disclosure is only an example, and is not limited thereby. Moreover, the group of the second partition plates 122 can define the air supply cavity 1102 in the gap on a side (i.e., the outer side) facing the gap. Thus, the structure of the aeration device 100 with a plurality of aeration cavities 1103 and the air supply cavity 1102 surrounding the aeration cavities 1103 is formed. The second partition plate 122 may be provided with the ventilation structure 160 to connect the air supply cavity 1102 and each aeration cavity 1103.

[0054] As an example, in order to enhance the strength of the second partition plate 122, especially as Figure 7 shown, the second partition plate 122 extends along the length direction of the aeration shell 110 and has a certain length, and at least one reinforcing portion (not shown) is provided on the second partition plate 122. In a further example, at least one reinforcing portion may be provided on the second partition plate 122 at a position corresponding to each aeration chamber 1103, so as to enhance the structural strength of each aeration chamber. The reinforcing portion may be implemented as a reinforcing rib.

[0055] Optionally, as Figure 7As shown, the first partition assembly has a recess on at least one side at the end away from the top of the aeration housing 1103, forming a side edge that maintains a gap with the inner wall of the adjacent aeration housing. Specifically, each of the first partitions 121 has a side edge 1211 (i.e., the end near the bottom) at the end away from the top of the aeration housing 110, formed by a recess on at least one side, maintaining the gap with the inner wall of the adjacent aeration housing 110. The side edge 1211 has an example of a curved shape, such as a broken line, a curve, or a straight line connecting curves; the example in the figure is a broken line shape. The side edge 1211 bends upward from the gap location that maintains the gap with the inner wall of the adjacent aeration housing 110 to abut against the inner wall of the adjacent aeration housing 110. The second partition 122 bends along the side edge to abut against the inner wall to define an air supply chamber on the side facing the gap. Specifically, the second partition 122 engages with the side edge 1211 in a form-fitting manner as follows: Figure 6 The partition divides the space into an air supply chamber 1102 and an aeration chamber 1103 located on opposite sides. The advantage of this structural design is that the volume ratio between the aeration chamber 1103 and the air supply chamber 1102 can be adjusted. Specifically, if the first partition 121 is designed to be completely separated from the inner wall of the adjacent aeration shell 110, the volume of the gap increases, meaning the volume of the air supply chamber 1102 increases while the volume of the aeration chamber 1103 decreases. Because the ventilation structure 160 is relatively low, a large portion of the upper volume of the air supply chamber 1102 becomes unusable, instead encroaching on and sacrificing the volume of the aeration chamber 1103, thus resulting in a lower aeration intensity for an aeration device of the same size. By designing the curved side edge 1211 of the first partition 121 and the cooperating second partition 122, the space above the portion of the second partition 122 that bends to the inner wall of the adjacent aeration shell 110 becomes the volume of the aeration chamber 1103. With the same volume of aeration device 100, the volume of the aeration chamber 1103 can be effectively increased, thereby increasing the aeration intensity. It is understood that by setting the side edge 1211 and the second partition 122 with different degrees of curvature, different volume ratios of the aeration chamber 1103 and the air supply chamber 1102 can be obtained.

[0056] Alternatively, in other embodiments, the first partition 121 may only be connected to the inner top wall of the aeration shell 110 and not to the inner side wall of the aeration shell 110. Instead, a second partition 122 is installed to connect with the first partition 121 and the inner top wall. In this case, a clearance gap is formed between the second partition 122 and the opposite inner side wall of the aeration shell 110, constituting an air supply chamber. Furthermore, the second partition 122 and the first partition 121 together form each aeration chamber. Therefore, it can be seen that there are various ways to assemble the aeration chamber and air supply chamber using a set of first partitions 121 and second partitions 122, and it is not limited to the figures shown.

[0057] Please refer to them together. Figure 7and Figure 8 , Figure 8 The diagram shows a side view of the second partition in an embodiment of this disclosure.

[0058] As can be seen, the side edge 1211 and the second partition 122 connected thereto extend upwardly at an angle to the inner wall of the aeration shell 110. In other embodiments, the side edge 1211 and the second partition 122 connected thereto may also be a right-angled bend structure, and are not limited thereto. Alternatively, in other embodiments, the side edge 1211 and the second partition 122 may also be an acute-angled bend, i.e., a downwardly inclined structure. In short, the bending angle of the side edge 1211 and the second partition 122 can be adjusted according to the required volume ratio between the aeration chamber 1103 and the air supply chamber 1102.

[0059] exist Figure 7 In this configuration, the first partition 121 and the second partition 122 are engaged with each other. The first partition 121 and the second partition 122 can be engaged with each other via a strip and a groove 1221, meaning the strip can be inserted into the groove 1221. Optionally, the strip and the groove 1221 can be interference-fitted for mutual locking and positioning. Exemplarily, the strip is formed on the side edge 1211 of the first partition 121, and the groove 1221 is formed on the second partition 122. Alternatively, in other embodiments, the objects on which the strip and the groove 1221 are located can be interchanged, and this is not a limitation.

[0060] In addition, Figure 3 It shows Figure 7 The state after the first partition 121 and the second partition 122 are engaged. Figure 8 As can be seen, the insert protrudes partially from the groove 1221 towards the bottom of the aeration shell 110. Since the first partition 121 and the second partition 122 can be made of a thermoplastic material, the protruding portion of the insert can serve as a thermoplastic weld point, which is melted away by thermoplastic welding to fix the first partition 121 and the second partition 122 at a single point. Utilizing the protruding portion of the thermoplastic material after interlocking as a weld point for thermoplastic welding to form a fixed connection eliminates the need for metal screws, reduces the risk of sewage corrosion, and provides a more robust thermoplastic fixation, effectively extending the lifespan of the aeration device.

[0061] It is understood that in other embodiments, if the first partition 121 is provided with a side edge 1211 on only one side, the second partition 122 may also be provided with only one on the corresponding side. Therefore, the number of second partitions 122 can be varied as needed and is not limited to the figure shown.

[0062] Back Figure 3 and Figure 4The specific structure of the ventilation structure 160 is described below. Optionally, the ventilation structure 160 may include at least one ventilation opening 162 formed at the bottom end of the partition structure 120, and at least one air supply hole unit 161 formed on the wall surface of the partition structure 120. As an example, the air supply hole unit 161 may be positioned above the ventilation opening 162.

[0063] As an optional example, each aeration chamber 1103 may have multiple ventilation openings 162 on its chamber wall (i.e., the portion of the aeration chamber 1103 enclosed by the partition structure 120), for example... Figure 3 and Figure 4 The four ventilation openings 162 shown are evenly distributed in pairs on a pair of opposing cavity walls of the aeration chamber 1103, cooperating with the annular continuous air supply chamber 1102 to uniformly introduce air into each aeration chamber 1103. Optionally, the four ventilation openings 162 can be arranged symmetrically around the central axis of the corresponding aeration chamber 1103. It is understood that in other embodiments, the number of ventilation openings 162 can vary; for example, a pair of ventilation openings 162 may be symmetrically distributed relative to the central axis of the aeration chamber 1103 on a pair of opposing cavity walls adjacent to the air supply chamber 1102. For example, in Figure 4 In this configuration, a pair of ventilation openings 162 can be arranged radially along the center of the aeration chamber 1103 on the pair of chamber walls, such as at positions A and B on the pair of chamber walls along a direction perpendicular to the width of the aeration shell 110. Alternatively, they can be staggered in the width direction, such as at positions C and D on the pair of chamber walls at an angle.

[0064] In some embodiments, at least two air supply hole units 161 are symmetrically distributed on a pair of opposing cavity walls adjacent to the air supply cavity 1102 of the aeration cavity 1103, relative to the central axis of the aeration cavity 1103. Figure 3 and Figure 4 The diagram shows that there is a pair of air supply hole units 161, which are staggered in the width direction and symmetrically arranged on the walls of the pair of chambers relative to the central axis of the aeration chamber 1103, so as to cooperate with the annular continuous air supply chamber 1102 to uniformly ventilate each aeration chamber 1103.

[0065] The air supply unit 161 may include at least one air supply hole 1611, and two air supply holes 1611 are shown in the figure. The size and number of air supply holes 1611 in each air supply unit 161 are related to the air supply volume from the air supply chamber 1102 to the aeration chamber 1103. Since the aeration device 100 is placed in the wastewater to be treated, if the air supply holes 1611 are too small, they are easily blocked by sludge; if the air supply holes 1611 are too large or there are too many, it can cause gas fluctuations. Therefore, the appropriate size and number of air supply holes 1611 can be selected according to the required air supply effect.

[0066] In other embodiments, the number of air supply port units 161 and the number of air supply ports 1611 included can also vary. In one example, there may be four air supply port units 161, located one-to-one in... Figure 2 and Figure 4 Above each vent opening 162, each air supply unit 161 may include only one air supply port 1611, which is consistent with... Figure 2 and Figure 4 In the embodiment, four ventilation openings 162 are used in conjunction with four air supply holes 1611 for ventilation. The ventilation volume is similar, but the structure can be different, and the uniformity may be better.

[0067] In addition, the ventilation structure 160 includes a higher-positioned air supply hole unit 161 and a lower-positioned ventilation opening 162. According to the aeration principle of the pulse aeration device, gas introduced into the air inlet 111 flows downwards into the air supply chamber 1102, lowering the water level in the air supply chamber 1102 so that the gas first connects to the higher-positioned air supply hole unit 161. Therefore, the ventilation unit is preferentially used to supply air from the air supply chamber 1102 to the aeration chamber 1103. When the air supply hole unit 161 is blocked and cannot supply air, the water level can be further lowered to connect the gas and the ventilation opening 162, still allowing air supply from the air supply chamber 1102 to the aeration chamber 1103. That is to say, the ventilation opening 162 serves as a backup for the air supply hole unit 161 to supply air from the air supply chamber 1102 to the aeration chamber 1103, achieving a "main-backup" redundant air supply design, which can effectively improve the reliability of the aeration device 100.

[0068] It should be noted that, since each aeration chamber 1103 is equipped with a corresponding ventilation structure 160, therefore Figure 3 and Figure 4 Only some parts are marked, not all of them. In other embodiments, the plurality of air outlets 112 and aeration chambers 1103 may not be arranged in a straight line, but may be arranged in an array such as a square, ring, or circle, and are not limited to the structure in this embodiment.

[0069] It is understood that the ventilation structure 160 shown in the figure is only an exemplary structure and can be changed according to the actual situation, such as adopting any selection or combination of ventilation openings and air supply holes.

[0070] For example Figure 9 and Figure 10 The structure of the aeration component 130 is described in detail below. Figure 9 The diagram shown is a top view of the aeration device 100 in an embodiment of this disclosure. Figure 10 exhibit Figure 9 A schematic diagram of the cross-sectional view along the EE direction.

[0071] The aeration component 130 is connected between the air outlet 112 and the aeration chamber 1103.

[0072] As an example, such as Figure 10 As shown, the aeration assembly 130 includes an air outlet pipe 131 and an air collection cup 132. The air outlet pipe 131 and the air collection cup 132 are coaxially fitted together (or eccentrically fitted in other embodiments). One end (the upper end) of the air outlet pipe 131 is connected to the inner top wall of the aeration shell 110 and communicates with the air outlet 112, while the other end (the lower end) away from the inner top wall of the aeration shell 110 has an air inlet 1311. The air collection cup 132 is fitted upwards outside the air outlet pipe 131, with a gap maintained between its upper end and the inner top wall of the aeration shell 110, forming an air collection port 1321 higher than the air inlet 112, and a discharge port 1322 at its bottom end. The discharge port 1322 is used to allow sludge sediment in the air collection chamber 1323 of the air collection cup 132 to be discharged from the discharge port 1322 into the aeration chamber 1103.

[0073] The working principle of the aeration device 100 is explained below. Gas is introduced through the air inlet 111 and flows downwards into the air supply chamber 1102. As the gas enters and rises in the air supply chamber 1102, it forces water out from the bottom of the aeration shell 110, thus lowering the water level in the air supply chamber 1102. When the water level drops to expose the air supply hole unit 161, the air supply chamber 1102 connects to the aeration chamber 1103 through the air venting unit to supply air to the aeration chamber 1103. Similarly, as gas is continuously introduced into the aeration chamber 1103, the water level in the aeration chamber 1103 decreases. Since the air collecting cup 132 is connected to the aeration chamber 1103 through the air collecting port 1321, the water level also decreases until the water level drops to expose the air inlet 1311 at the bottom of the air collecting cup 132. Gas can enter the air collecting cup 132 through the air collecting port 1321 and then enter the air outlet pipe 131 through the air inlet 1311 to be discharged through the air outlet 112, so that it can be diverted and output by the gas diverter 140 to form aeration. After aeration is formed, the sewage in the aeration chamber 1103 rises and refills the aeration chamber 1103. Subsequently, by continuously filling the air collecting chamber 1323 of the air collecting cup 132 with air, the aeration device 100 will continuously repeat the above aeration process. Thus, the aeration device 100 will form an intermittent aeration. To facilitate the sewage being pushed out of the air supply chamber 1102 and the aeration chamber 1103, it can be as follows... Figure 4 As shown in the figure, the aeration shell 110 may also be provided with overflow channels 1104 for water supply overflow at the bottom of the two inner side walls.

[0074] exist Figure 10In this process, the air outlet pipe 131 can be integrally formed with the aeration shell 110, or the air outlet pipe 131 can be fixedly connected to the inner top wall of the aeration shell 110 by means of snap-fit, heat fusion or other methods.

[0075] like Figure 10 As can be seen, the air outlet pipe 131 is a pipe with a straight central axis that is coaxial with the air outlet 112, and the air collecting cup 132 is a cup that is coaxial with the air outlet pipe 131 and extends in a straight line.

[0076] Alternatively, in other optional embodiments, the air collecting cup 132 and the air outlet pipe 131 may be eccentrically positioned along one extension direction of the aeration shell 110, i.e., their central axes are not collinear. Alternatively, the air outlet pipe 131 and the air outlet hole 112 may be eccentrically positioned along the width direction of the aeration shell 110. Alternatively, the air outlet pipe 131 and the air outlet hole 112 may be eccentrically positioned along both the length and width directions of the aeration shell 110. The air outlet pipe 131 is more conducive to breaking the instantaneous balance of pulse aeration, making pulse aeration easier to occur and more uniform, unaffected by environmental factors.

[0077] For example Figure 4 and Figure 10As shown, optionally, a baffle 150 may be provided in the flow channel connecting the air inlet 111 of the aeration shell 110 to the air supply chamber 1102. When gas flows into the air inlet 111, the flow velocity may be too high, causing it to directly rush out of the air supply chamber 1102. Furthermore, the downward rush of gas may create turbulence, affecting the uniformity of air supply to the aeration chamber 1103 and potentially causing localized disturbances. The baffle 150 can mitigate the impact force of the rushing gas, allowing the gas impacting the baffle 150 to be blocked and slowed down before flowing into the adjacent air supply chamber 1102. This ensures a smooth air supply to the air supply chamber 1102, effectively balancing and stabilizing the air supply / aeration of the aeration device 100. As an example, if the flow channel is vertical, the baffle 150 can be located below the air inlet 111, either directly below or offset from directly below. Alternatively, in other embodiments, the flow channel may be of other shapes or segments, and is not limited thereto. For example, the baffle 150 may be a planar, polygonal, or arc-shaped baffle, etc. For example, the baffle 150 may be integrally connected to the aeration shell 110. Further optionally, the baffle 150 may be integrally connected to the sidewall of the aeration shell 110 adjacent to the air inlet 111 (for example, one end sidewall of the aeration shell 110 in one extending direction). To enhance the strength of the baffle 150, its opposite ends may be respectively connected to the end sidewall and a first partition 121 adjacent to the end sidewall, while the other two ends of the baffle 150 maintain a distance from the corresponding inner sidewall of the aeration shell 110 to allow gas to enter the air supply chamber 1102.

[0078] In some embodiments, the aeration shell 110, the air outlet pipe 131 which can be integrally connected to the aeration shell 110, the first partition 121, the second partition 122, and the air collection cup 132, etc., can all be made of heat-fusible materials. This allows for the convenient use of heat-fusion welding to fix these parts, eliminating the need for screws or other metal parts, reducing the risk of corrosion by sewage, and also improving the reliability between parts and reducing the internal vibration of the aeration device 100 underwater.

[0079] In another embodiment of this disclosure, a membrane module may also be provided. The membrane module includes an aeration device 100 as described in any of the previous embodiments, and a filter membrane positioned above the aeration device 100. The pulse aerator aeration process creates a scrubbing and cleaning effect on the filter membrane.

The aeration chamber and air supply chamber on both sides of the second separating component can be separated by the snap-fit ​​fit between the side edge of the first separating component and the installed curved second separating component, making installation convenient and efficient.
