[0039] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0040] like Figure 1 , 2 As shown in Figures 4 and 5, the utility model provides an aeration and sedimentation integrated sewage treatment device, including a tank body 1, a sludge discharge component 2, and an aeration component 3. A discharge port is provided at the bottom of the tank body 1, and the inner diameter of the discharge port at least partially decreases along the discharge direction; the feed end of the sludge discharge component 2 is connected with the discharge port; the aeration component 3 includes a blast piece 31, an air intake main pipe 32 and a plurality of flexible air intake branch pipes 33, the air intake end of the air intake main pipe 32 is connected with the air outlet end of the blast piece 31, and the plurality of flexible air intake branch pipes 33 are distributed at intervals along the length direction of the air intake main pipe 32, one end of the flexible air intake branch pipe 33 is connected with the air intake main pipe 32, and the other end is inserted into the tank body 1, and the flexible air intake branch pipe 33 is provided with a plurality of exhaust holes at intervals.

[0041] Specifically, the sewage first enters the tank body 1, and the air blowing member 31 is started. The air blowing member 31 generates compressed air, which is transported to each flexible air inlet branch 33 through the air inlet main pipe 32. The flexible air inlet branch 33 is inserted into the tank body 1, and multiple exhaust holes are arranged at intervals in the length direction thereof to release the compressed air evenly into the sewage. The compressed air forms bubbles in the sewage, increases the dissolved oxygen content in the sewage, and promotes the growth and reproduction of aerobic microorganisms. These microorganisms can decompose organic matter in the sewage, thereby achieving the purpose of purifying the sewage. After the aerobic treatment, the sewage is precipitated. During the precipitation process, particulate impurities gradually gather toward the bottom. Since the inner diameter of the discharge port at the bottom of the tank body 1 is gradually reduced at least partially along the discharge direction, this is conducive to the concentration and discharge of sludge. The feed end of the sludge discharge component 2 is connected to the discharge port, which is used to discharge the sludge settled at the bottom of the tank.

[0042] The present invention integrates aeration and sedimentation functions, simplifies the sewage treatment process, and reduces the floor space. A flexible air intake branch pipe 33 is adopted, and the exhaust holes on the flexible air intake branch pipe 33 can evenly release compressed air into the sewage to improve the aeration effect. Moreover, when it is necessary to clean the tank body 1, the flexible air intake branch pipe 33 can be fished out, and the tank body 1 can be cleaned at this time, and the flexible air intake branch pipe 33 will not interfere with the cleaning and discharge of sludge.

[0043] It should be understood that the mud discharge component 2 can be a screw conveyor, a mud discharge pipe provided with a valve, a mud discharge pump, etc.

[0044] It should be understood that an anaerobic tank may be provided outside the tank body 1 to treat the sewage by anaerobic and aerobic treatments in the anaerobic tank.

[0045] It should be understood that the sludge in the tank body 1 can settle naturally under the action of gravity, or the tank body 1 can be filled with flocculants such as polyaluminum chloride, ferric chloride, polyacrylamide and polyaluminum ferric chloride for flocculation and precipitation.

[0046] It should be understood that the pool body 1 can be a square, long strip, or cylindrical structure with a hollow interior and an open top.

[0047] like Figure 4 and Figure 5 As shown, in one embodiment, the aeration assembly 3 further includes a plurality of counterweights 34 , and the plurality of counterweights 34 are respectively connected to the bottoms of the plurality of flexible air inlet branches 33 .

[0048] Specifically, the function of the counterweight 34 is to increase the weight of the flexible air intake branch pipe 33 so that it can maintain a vertical position in the pool body 1 to prevent it from being deflected or floating due to the action of water flow or air flow. When the air blowing member 31 generates compressed air and transmits it to the flexible air intake branch pipe 33 through the air intake main pipe 32, the counterweight 34 will not affect the flow and discharge of air. The exhaust holes on the flexible air intake branch pipe 33 can still release the compressed air evenly into the sewage.

[0049] It should be understood that the counterweight 34 can be made of corrosion-resistant materials, and the material of the counterweight 34 can be stainless steel, brass, polymer materials, etc.

[0050] like Figure 4 and Figure 5 As shown, in one embodiment, the counterweight member 34 includes a counterweight ball 341, the interior of the counterweight ball 341 is hollow and the outer wall begins to have multiple aeration holes, the aeration holes are connected to the interior of the counterweight ball 341, and the counterweight ball 341 is connected to the other end of the flexible air intake branch pipe 33 and is connected to the flexible air intake branch pipe 33.

[0051] Specifically, the compressed air generated by the air blowing member 31 is transported to the flexible air inlet branch 33 through the air inlet main pipe 32, and then enters the inside of the weighted ball 341; the hollow structure inside the weighted ball 341 can reduce its weight, making it easier to install and maintain. At the same time, the aeration holes on the outer wall can evenly release the compressed air into the sewage, further improving the aeration effect.

[0052] like Figure 4 and Figure 5As shown, in one of the embodiments, one side of the counterweight ball 341 is open, and the counterweight member 34 also includes an end cover 342, which is arranged relative to the opening of the counterweight ball 341 and is detachably connected to the open end of the counterweight ball 341. The end cover 342 is connected to the flexible air intake branch pipe 33 and is provided with a connecting hole connecting the flexible air intake branch pipe 33 and the counterweight ball 341.

[0053] Specifically, the compressed air generated by the air blowing member 31 is transported to the flexible air intake branch pipe 33 through the air intake main pipe 32, and then enters the interior of the weighted ball 341 through the connecting hole on the end cover 342; since the interior of the weighted ball 341 is hollow and the outer wall is provided with a plurality of aeration holes, the compressed air can be released into the sewage through these aeration holes; thus, the weighted ball 341 not only stabilizes the flexible air intake branch pipe 33, but also assists in aeration; the end cover 342 is detachably connected to the open end of the weighted ball 341, which facilitates the cleaning and maintenance of the interior of the weighted ball 341. When the weighted ball 341 or the end cover 342 is damaged, it can be replaced separately to reduce the maintenance cost.

[0054] like Figure 4 and Figure 5 As shown, in one embodiment, an internal thread is formed inside the opening, an external thread is formed on the outer wall of the end cover 342, and the end cover 342 is threadedly connected to the opening.

[0055] The end cap 342 is connected to the opening of the weight ball 341 by a thread, and this connection mode has high sealing and stability. At the same time, the threaded connection is easy to install and disassemble, and it is convenient to clean and maintain the inside of the weight ball 341.

[0056] It should be understood that the end cover 342 and the weight ball 341 may be detachably connected by bolts, screws, snaps, etc.

[0057] like Figure 1 , 3 As shown in FIG. 4 , in one embodiment, the aeration and sedimentation integrated sewage treatment device further includes a bracket 4 , which is disposed on the top of the tank body 1 ; the air inlet main pipe 32 is connected to the bracket 4 , and is connected to the tank body 1 via the bracket 4 .

[0058] Specifically, the bracket 4 provides a stable support for the air intake main pipe 32 , ensuring that it remains horizontal or at a proper angle on the top of the pool body 1 . This helps to evenly deliver the compressed air to each flexible air intake branch pipe 33 .

[0059] It should be understood that the type of the bracket 4 can be a bracket 4, a frame, etc. formed by a combination of various rods, profiles and plates; the bracket 4 can be fixed to the pool body 1 by erection, or it can be fixed to the top of the pool body 1 by bolts and screws.

[0060] like Figure 4 As shown, in one of the embodiments, the aeration and sedimentation integrated sewage treatment device further includes an aerobic filler assembly 5 , which is inserted into the tank body 1 and detachably connected to the bracket 4 .

[0061] Specifically, the filler rack 51 provides support and fixation for the aerobic filler attachment portion 52, ensuring its correct position in the tank body 1; the compressed air generated by the aeration assembly is released into the sewage through the aeration holes on the counterweight ball 341, providing oxygen for aerobic microorganisms and promoting their growth and reproduction; when the aerobic filler assembly 5 needs to be replaced or cleaned, it can be removed from the bracket 4 and the corresponding operation can be performed.

[0062] like Figure 4 As shown, in one embodiment, the aerobic filler assembly 5 includes a filler frame 51 and a plurality of aerobic filler attachment portions 52 . The filler frame 51 is detachably connected to the bracket 4 and inserted into the tank body 1 . The aerobic filler attachment portions 52 are connected to the filler frame 51 .

[0063] Specifically, through the aerobic filler attachment portion 52, the metabolic activity of the aerobic filler on the aerobic filler portion effectively degrades the organic pollutants in the sewage, thereby improving the treatment quality of the sewage; the detachable design of the aerobic filler assembly 5 makes maintenance and replacement simple and quick, thereby reducing the maintenance cost of the equipment; when it is necessary to clean the tank body 1, the filler rack 51 can be removed to clean the inside of the tank body 1, at which time the filler rack 51 will not interfere with the cleaning of the tank body 1, and when the aerobic filler attachment portion 52 is maintained, the filler rack 51 can also be removed to facilitate the maintenance of the aerobic filler attachment portion 52.

[0064] like Figure 4 As shown, in one embodiment, the interior of the aerobic filler attachment portion 52 is hollow and has a fixing hole communicating with the interior. An aerobic filler layer 53 is disposed in the aerobic filler attachment portion 52 .

[0065] Specifically, the aerobic filler layer 53 is usually composed of porous materials or biofilm carriers with high specific surface areas, which can provide a place for aerobic microorganisms to attach and grow. When sewage flows through the aerobic filler layer 53, the microorganisms use the organic matter in the sewage to metabolize, thereby degrading the organic pollutants in the sewage. The compressed air generated by the aeration assembly is released into the sewage through the aeration holes on the counterweight ball 341, providing the required oxygen for aerobic microorganisms and promoting their growth and reproduction. The hollow structure and fixed holes of the aerobic filler attachment part 52 allow the sewage to enter and fully contact with the aerobic filler layer 53, thereby improving the sewage treatment efficiency. In the process of degrading organic pollutants, the microorganisms in the aerobic filler layer 53 will produce some metabolic products, such as carbon dioxide and water, which can flow out with the sewage through the fixed holes.

[0066] It should be understood that the aerobic filler layer 53 can be porous spherical fillers, activated carbon, high molecular polymer elastic fillers, etc., and the aerobic bacteria attached to the aerobic filler layer 53 can be bacteria or fungi. The aerobic bacteria can be Bacillus, Pseudomonas, Flavobacterium, Micrococcus, Rhodospirillum, etc.; the aerobic fungi can be yeasts, molds, etc.

[0067] like Figure 4 As shown, in one embodiment, the aerobic filler attachment portion 52 is detachably connected to the filler frame 51 .

[0068] The detachable connection makes it easier to replace and clean the aerobic filler attachment portion 52 , thereby reducing maintenance costs.

[0069] It should be understood that the aerobic filler attachment portion 52 can be detachably fixed to the filler frame 51 by means of bolts, screws, buckles, etc.

[0070] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
