Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, specifically to a high-efficiency heavy ion microporous membrane MABR module device. Background Technology

[0002] A MABR (Membrane Aerated Biofilm Reactor) is a wastewater treatment device that utilizes the synergistic effect between an oxygen-selective permeable membrane and an attached biofilm. It employs a permeable membrane to transfer oxygen to the biofilm attached to its surface, while simultaneously diffusing substrates such as ammonia nitrogen and organic matter from the wastewater into the biofilm. The MABR reactor operates within an overall anoxic environment. The aerobic biofilm growing on the MABR membrane (dominated by nitrifying bacteria) and the denitrifying bacteria suspended in the external and anoxic environment simultaneously achieve nitrification and denitrification, thereby enhancing the removal of ammonia nitrogen and total nitrogen from the wastewater. As wastewater flows around the MABR membrane, pollutants in the water enter the biofilm under the influence of concentration gradient and microbial adsorption. Through biological metabolism and proliferation, they are utilized by microorganisms, assimilating the pollutants into microbial cells, which are then fixed on the biofilm or decomposed into inorganic metabolites, thus achieving water purification and recycling.

[0003] A search revealed that CN219194678U discloses a high-efficiency heavy ion microporous membrane MABR module device. In this device, the installation direction of the heavy ion microporous membrane tubes is changed from the original horizontal arrangement to a vertical arrangement. Air enters from the lower end of the heavy ion microporous membrane tubes, passes through the heavy ion microporous membrane tubes, and oxygen in the air dissolves into the water through the micropores of the heavy ion microporous membrane tubes. The exhaust gas is discharged from the upper end of the heavy ion microporous membrane tubes. The vertical heavy ion microporous membrane tubes cannot accumulate sludge, which can effectively solve the problem of activated sludge easily accumulating on the outer wall of the membrane tubes. However, the aeration pipe and the membrane frame are an integrated welded structure, which requires replacement of the whole when damaged, resulting in high maintenance costs. In particular, the aeration holes of the aeration pipe are small in diameter and are easily covered and blocked by biofilm. The non-continuous operation of pulse aeration results in a lack of airflow flushing at the orifices during shutdown, providing a time window for biofilm growth.

[0004] Therefore, it is of great importance to design a high-efficiency heavy-ion microporous membrane MABR module to solve the above-mentioned defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention designs a high-efficiency heavy ion microporous membrane MABR module device. This device aims to solve the technical problems of high maintenance costs and easy blockage of aeration pipes by biofilm in existing high-efficiency heavy ion microporous membrane MABR module devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example: Please refer to Figures 1-6 This utility model provides a technical solution:

[0029] A high-efficiency heavy ion microporous membrane MABR module device includes a square tube frame 1, with multiple sets of membrane curtains 2 fixedly installed inside the square tube frame 1, and a membrane purging mechanism 3 fixedly installed at the bottom inside the square tube frame 1.

[0030] First, in this embodiment, the specific structure of the membrane purging mechanism 3 is as follows:

[0031] The membrane purging mechanism 3 includes two sets of aeration boxes 301 fixedly installed inside the bottom of the square tube frame 1. Multiple air outlets 302 are opened on the top of each aeration box 301, and each air outlet 302 is threadedly connected to an aeration cover 303. A cover 304 is fitted onto both the front and rear ends of each aeration box 301. A protective cover 305 is fixedly installed on the top of each aeration box 301, located between the two covers 304. The two sets of aeration boxes 301 are connected by a connecting pipe 306. Mounting seats 307 are fixedly connected to both the front and rear ends of the bottom of each aeration box 301. The left and right ends of the mounting seats 307 are fixedly connected to the square tube frame 1 by bolts. After entering the aeration box 301, the biofilm is evenly distributed to the two sets of aeration boxes 301 via the connecting pipe 306. At the same time, the number of aeration boxes 301 can be flexibly increased through the connecting pipe 306 to adapt to different treatment scale requirements. The mounting base 307 is fixed to the square tube frame 1 with bolts, supporting the overall structure of the aeration box 301, and can also be disassembled. Through modular design, the aeration box 301 and its external components can be independently disassembled and replaced without the need for overall scrapping, thereby reducing maintenance costs. The protective cover 305 physically isolates the biofilm during use, preventing direct coverage of the aeration cover 303 and further avoiding clogging problems.

[0032] Furthermore, an air guide pipe 308 is fixedly installed on the outer side of one of the box covers 304, and a solenoid valve 309 is installed at the bottom end of the air guide pipe 308. An aeration disc 310 is provided on the inner side of the aeration cover 303. The aeration disc 310 is a corundum microporous aeration disc. Sealing edges 311 are fixedly connected to both the front and rear ends of the aeration box 301. The box cover 304 passes through, and the sealing edges 311 are sleeved on both the front and rear ends of the aeration box 301. The front and rear ends of the protective cover 305 are fixedly connected to the box cover 304 and the sealing edges 311 by fixing bolts 312. Air enters through the air guide pipe 308. The aeration box 301 is evenly distributed to two sets of aeration boxes 301 via the connecting pipe 306. The solenoid valve 309 controls pulse aeration. The airflow is sprayed out from the air outlet 302 at the top of the aeration box 301 and refined into tiny bubbles by the corundum microporous aeration disc 310 inside the aeration cover 303. The sealing edge 311 and the box cover 304 ensure the airtightness of the aeration box 301 and prevent sewage from seeping in. After unscrewing the fixing bolt 312, the box cover 304 and the protective cover 305 can be disassembled and maintained, which facilitates the individual replacement of maintenance parts and reduces maintenance costs.

[0033] Then, multiple sets of through grooves 313 are opened on the inner side of the protective cover 305. Multiple sets of baffles 314 are fixedly connected inside the multiple sets of through grooves 313. Dispersion holes 315 are formed between the multiple sets of baffles 314. After the bubbles are ejected through the through grooves 313, they are further dispersed by the baffles 314 inside the through grooves 313 and evenly distributed through the dispersion holes 315, thereby improving the oxygen mass transfer efficiency.

[0034] Furthermore, each of the multiple membrane curtains 2 is composed of multiple heavy ion membrane tubes 201. Inside the square tube frame 1, at both ends of the heavy ion membrane tubes 201, a connecting pipe 202 is fixedly installed. An exhaust pipe 203 and an intake pipe 204 are respectively installed at the upper and lower ends of the front of the square tube frame 1, and both the exhaust pipe 203 and the intake pipe 204 are fixedly connected to the connecting pipe 202. Air enters the lower connecting pipe 202 from the intake pipe 204 and is distributed to the lower end of each heavy ion membrane tube 201. Oxygen permeates to the outer biofilm through the micropores of the heavy ion membrane tube 201. The exhaust gas is collected from the upper end of the heavy ion membrane tube 201 to the upper connecting pipe 202 and finally discharged through the exhaust pipe 203.

[0035] Secondly, both ends of the connecting tube 202 are fixedly connected to the square tube frame 1 by mounting screws 205. The connecting tube 202 is fixed inside the square tube frame 1 by mounting screws 205, forming a closed airflow channel with the heavy ion membrane tube 201. The ventilation allows for easy disassembly and maintenance of the connecting tube 202.

[0036] Finally, quick-release heads 206 are fixedly connected to both ends of the heavy ion membrane tube 201. The quick-release heads 206 are engaged with the connecting tube 202 through the mounting groove 207. A connecting hole 208 is provided at the connection between the mounting groove 207 and the quick-release head 206. A rubber sealing ring 209 is embedded inside the mounting groove 207 and outside the connecting hole 208. The quick-release heads 206 at both ends of the heavy ion membrane tube 201 are engaged with the connecting tube 202 through the mounting groove 207. The connecting hole 208 ensures gas flow. The rubber sealing ring 209 is embedded at the connection between the mounting groove 207 and the quick-release head 206 to prevent gas leakage. The quick-release design supports the replacement of the heavy ion membrane tube 201 without disassembling the entire assembly, which further improves the convenience of maintenance and reduces maintenance costs.

[0037] In this embodiment, the specific implementation scenario is as follows: When the membrane curtain 2 is working, air enters the lower connecting pipe 202 from the air inlet pipe 204 and is distributed to the lower end of each heavy ion membrane tube 201. Oxygen permeates to the outer wall biofilm through the micropores of the heavy ion membrane tube 201. Exhaust gas is collected from the upper end of the heavy ion membrane tube 201 to the upper connecting pipe 202 and finally discharged through the exhaust pipe 203. The quick-release heads 206 at both ends of the heavy ion membrane tube 201 are engaged with the connecting pipe 202 through the mounting groove 207, and the connecting hole 208... To ensure gas flow, a rubber sealing ring 209 is embedded in the mounting groove 207 at the connection point with the quick-release head 206 to prevent air leakage. The quick-release design allows for the replacement of the heavy ion membrane tube 201 without disassembling the entire assembly. The air used by the membrane purging mechanism 3 enters the aeration box 301 through the air guide pipe 308 and is evenly distributed to the two sets of aeration boxes 301 via the connecting pipe 306. The solenoid valve 309 controls pulse aeration, and the airflow is ejected from the air outlet 302 at the top of the aeration box 301 and passes through the aeration cover 303. The inner corundum microporous aeration disc 310 is refined into tiny bubbles. After the bubbles are ejected through the through groove 313, they are further dispersed by the baffle 314 inside the through groove 313 and evenly distributed through the dispersion holes 315, improving oxygen mass transfer efficiency. The mounting base 307 is fixed to the square tube frame 1 with bolts, supporting the overall structure of the aeration box 301 and allowing for disassembly. After unscrewing the fixing bolts 312, the box cover 304 and the protective cover 305 can be disassembled and maintained, facilitating the individual replacement of maintenance components. The protective cover 305 physically isolates the biofilm during use, preventing direct coverage of the aeration cover 303 and further avoiding clogging problems. The entire operation process is simple and convenient. Through modular design, the aeration box 301 and its external components can be independently disassembled and replaced without the need for overall scrapping, thereby reducing maintenance costs. At the same time, the quick-release design at both ends of the heavy ion membrane tube 201 supports replacement without disassembling the entire assembly, further improving maintenance convenience and reducing maintenance costs.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
