Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a liftable modular filler aeration coupling device for sewage treatment. Background Art

[0002] The activated sludge process is a widely used and effective traditional wastewater treatment process, primarily consisting of an aeration tank, secondary sedimentation tank, aeration system, and sludge return system. Aerobic microorganisms, under aeration conditions, oxidize and decompose organic matter in wastewater into harmless substances such as water and carbon dioxide, while also adsorbing suspended solids and other substances, thereby removing organic matter from wastewater.

[0003] In existing sewage treatment technology, the composite packing in aeration tanks is fixed by upper and lower fixed brackets, and the packing is densely distributed. If the packing, lower aeration pipes, and aerators need to be replaced, repaired, or cleaned, the sewage treatment system must first be shut down. Then, the tanks must be pumped out, the sludge removed, and some of the packing removed. The packing and aeration system must then be replaced, repaired, and cleaned manually at the bottom of the tanks. This makes replacement, repair, and cleaning of the packing, lower aeration pipes, and aerators difficult, impacting the normal operation of the sewage treatment plant and even causing production halts.

[0004] For example, a patent document in China discloses a "sewage pool using aeration equipment for sewage treatment," with publication number CN206901866U. The patent includes a sewage pool and an aeration device, characterized in that: the sewage pool is provided with a water inlet and a drain outlet, a diversion spacer is provided in the sewage pool, the aeration device is arranged in sections at the lower end of the sewage pool, and a plurality of impurity troughs are provided at the bottom of the sewage pool, the lower ends of the impurity troughs are open. A shortcoming of this patent is that the aeration device is arranged at the bottom of the sewage pool. If the aeration device needs to be replaced or repaired, it is necessary to manually go down to the bottom of the pool to operate it, and it is also necessary to pump water and drain mud from the sewage pool, which makes maintenance more difficult and costly, and may lead to problems such as shutdown during maintenance. Utility Model Content

[0005] The utility model is intended to overcome the problem in the prior art that, when repairing and replacing the aeration equipment in the aeration tank, it is necessary to pump out water, drain mud, and perform operations at the bottom of the tank, which makes the operation difficult and may affect production. The utility model provides a sewage treatment liftable modular filler aeration coupling device, which can carry out operations such as repair, replacement, and cleaning of the aeration device without pumping water, and will not affect the normal operation of the sewage station.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model discloses a liftable modular filler aeration coupling device for sewage treatment, comprising a frame module and a hoisting structure, wherein an aeration device and a filler bracket are installed in the frame module, and the hoisting structure comprises a hoisting piece, one end of which is connected to the frame module.

[0008] In this application, when the aeration device needs to be inspected, replaced, or cleaned, it can be lifted up to the surface of the aeration tank through the lifting structure, so that the aeration device can be operated without going down to the bottom of the tank, and there is no need to pump water, discharge mud, etc., which will not affect the normal operation of the sewage station and save maintenance costs.

[0009] Preferably, the hoisting structure includes a hoisting bracket and a hoisting wheel, the hoisting member passes through the hoisting wheel, and one end of the hoisting member is connected to a hoisting drive structure. The hoisting drive structure can drive the hoisting member to lift the frame module.

[0010] Preferably, the hanging bracket is installed on a hanging base.

[0011] Preferably, the hoisting bracket is provided with a steering handle, and the hoisting bracket includes a steering column mounted in the hoisting base. This structure allows the hoisting bracket to rotate, thereby allowing the frame module to be moved from above the aeration tank to outside the tank, making it easier to perform maintenance, replacement, cleaning, etc.

[0012] Preferably, the present application further comprises a lifting guide rod mounted on the aeration tank wall, and the frame module is provided with a lifting pulley mounted on the lifting guide rod. The lifting guide rod can prevent the frame module from being limited during the lifting process and causing a large amount of shaking.

[0013] Preferably, the aeration tank is provided with a plurality of said frame modules. When the aeration device in one frame module is under repair, replacement or cleaning, the other aeration devices can still operate normally, so that the operation of the aeration tank is not affected.

[0014] Preferably, the hoisting base is mounted on a base moving track, the length direction of which is arranged along the arrangement direction of the plurality of frame modules. With this structure, one hoisting structure can be applied to multiple frame modules at the same time, saving cost and space.

[0015] Preferably, the aeration device is connected to an aeration hose, which can facilitate the lifting of the frame module without disassembling the pipeline.

[0016] Preferably, the present application also includes a walkway board and a railing located on one side of the hoisting structure.

[0017] Therefore, the utility model has the following beneficial effects: (1) the aeration device can be inspected, replaced, cleaned, etc. without pumping water, which will not affect the normal operation of the sewage station; (2) the lifting process of the frame module is stable.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1, as Figure 1 As shown, a sewage treatment liftable modular filler aeration coupling device is used for an aeration tank, including a frame module 1 and a lifting structure.

[0026] The frame module 1 is located at the bottom of the aeration tank. The aeration tank is the key to the aerobic activated sludge process. The wastewater enters the aeration tank after primary treatment such as adjusting the p value, removing oil, and homogenizing. Oxygen is introduced into the aeration mixture through mechanical, blasting and other aeration methods. The microorganisms in the mixture oxidize and decompose the organic matter in the influent in the presence of dissolved oxygen. The aeration tank utilizes aerobic microorganisms in the sewage to digest and degrade the organic matter in the sewage in the presence of free oxygen, thereby stabilizing and rendering it harmless. The aeration tank is in the form of a contact oxidation tank. Fillers are provided in the tank. The oxygenated sewage immerses all the fillers and flows through the fillers at a certain flow rate. Part of the microorganisms is fixed to the surface of the filler in the form of a biofilm, and part is suspended in the water in the form of flocs. Therefore, it has the characteristics of both a biological filter and an activated sludge process. When the biofilm grows to a certain thickness, the microorganisms near the filler wall will undergo anaerobic metabolism due to lack of oxygen. The generated gases and the scouring effect of aeration will cause part of the biofilm to fall off, promoting the growth of new biofilm and forming biological metabolism.

[0027] Frame module 1 includes an aeration device and a packing support, which is equipped with a composite packing. This composite packing is developed based on soft and semi-soft packing, combining the advantages of both. Its structure consists of a double-ring plastic ring, which is replaced with a plastic disc press buckle. Acetylated fiber or polyester yarn is pressed against the rings, ensuring even fiber distribution. The inner ring is composed of snowflake-shaped plastic branches, which not only form biofilms but also effectively cut through air bubbles, increasing oxygen transfer and utilization. This ensures sufficient exchange of water and air between biofilms and effectively treats organic matter in the water.

[0028] The aeration device is located below the filler support, and includes a plurality of aerators and an aeration channel connecting the plurality of aerators. The aeration channel is connected to an aeration hose 6, and the aeration hose 6 is used to connect to an air compressor installed outside the aeration tank.

[0029] The hoisting structure includes a hoisting base 2, a hoisting bracket 3, a hoisting wheel 4, and a hoisting member 5. The hoisting base 2 is installed at the upper edge of the aeration tank, one end of the hoisting bracket 3 faces the aeration tank, and the hoisting wheel 4 is installed at the end of the hoisting bracket 3 facing the aeration tank. The hoisting member 5 passes through the hoisting wheel 4, one end of the hoisting member 5 is connected to the frame module 1, and the other end is connected to the lifting drive structure 7. The hoisting member 5 can be a rope with higher strength or a chain. When the hoisting member 5 is a chain, the hoisting wheel 4 is correspondingly selected to be compatible with it. In this embodiment, the lifting drive structure 7 is a drive motor.

[0030] Beside the edge of the aeration tank, a walkway plate 8 and a handrail 9 are provided to facilitate the operator to walk and operate safely.

[0031] When the aeration device needs to be repaired or the filler needs to be cleaned and replaced, the frame module 1 is lifted upward by the lifting drive structure 7 and the lifting parts 5, so that the frame module 1 with the aeration device and the filler bracket leaves the bottom of the aeration tank, thereby facilitating maintenance.
