Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to MABR gas supply components and wastewater treatment systems. Background Technology

[0002] MABR (Membrane Aerated Biofilm Reactor) is an advanced wastewater treatment technology that combines a gas separation membrane with a biofilm reactor. It utilizes the membrane's permeability to provide oxygen to microorganisms while simultaneously achieving efficient pollutant degradation. Through the synergistic effect of bubble-free aeration and the biofilm, MABR technology significantly improves oxygen utilization and wastewater treatment efficiency, and is widely used in municipal wastewater, industrial wastewater treatment, and small-scale decentralized wastewater treatment systems.

[0003] The common structure in current MABRs is as follows: several membrane fiber units are installed in a support frame (or basket), and each membrane fiber unit is connected to the gas supply pipe through a connector. The connector is generally an external threaded pipe connector, which is tightened after installation to fix it. Since a set of MABRs generally has dozens of membrane fiber units, the connection between each membrane fiber unit and the gas supply pipe requires a tightening step, which makes the installation and disassembly cumbersome and inefficient. It is not convenient for the early assembly and production as well as the later maintenance work. In view of the above defects, this application is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an MABR gas supply component and a wastewater treatment system, which solves the problem that the current MABR and gas pipe connection operation is relatively cumbersome, resulting in low assembly and maintenance efficiency.

[0005] To address the aforementioned problems, this utility model provides an MABR air supply assembly and a wastewater treatment system, including an air supply connector, an air supply pipe, a clamping mechanism, and a socket structure. The air supply connector includes a MABR connection end and an air supply connection end. The air supply connection end includes a conical head end, a fixing groove, and a positioning surface. Several sealing rings are provided on the conical head end. The socket structure is installed on the air supply pipe and includes several insertion holes connected to the air supply pipe. Each insertion hole has a conical opening for engaging with the conical head end. The inner wall of the conical opening has a sealing groove for accommodating the sealing rings. The clamping mechanism includes an insert body, a clamping plate, and a bolt assembly. An insert body is provided in each insertion hole, and all insert bodies are connected to the clamping plate. The clamping plate is connected to the bolt assembly. In the locked state, the displacement of the clamping plate is controlled by operating the bolt assembly, causing the insert body to be inserted into the fixing groove and locked.

[0006] According to one embodiment of the present invention, each socket is provided with two sets of inserts symmetrically arranged vertically, the upper and lower inserts being connected to the upper and lower clamping plates respectively, and the bolt assembly being located at both ends of the clamping plates.

[0007] According to one embodiment of the present invention, the insert is a semi-annular structure.

[0008] According to one embodiment of the present invention, the insert and the fixing groove are interference fit.

[0009] According to one embodiment of the present invention, a flexible hose section is provided on the gas supply connector.

[0010] The wastewater treatment system includes the aforementioned MABR air supply component, MABR membrane module, tank body, and oxygen supply module. The oxygen supply module is connected to the MABR membrane module via the MABR air supply component, and the MABR membrane module is disposed in the tank body.

[0011] According to one embodiment of the present invention, the oxygen supply module is an oxygen generator or a liquid oxygen storage tank.

[0012] According to one embodiment of the present invention, the oxygen supply module is connected to the gas supply pipe in the MABR gas supply assembly through an oxygen control valve, a booster fan and an oxygen flow meter.

[0013] The beneficial effects of this utility model are that, through the design of the gas supply connector, gas supply pipe, clamping mechanism, and socket structure, when connecting the gas supply pipe to the MABR, the conical ends of all gas supply connectors are inserted into the sockets. The operating bolt assembly brings the upper and lower clamping plates closer to each other, allowing the insert to be inserted into the fixing groove to complete the locking and perform multiple seals. This means that during installation, the gas supply connectors only need to be tightened once after insertion to completely fix all gas supply connectors, greatly improving the efficiency of initial assembly and subsequent disassembly and maintenance.

Preferably, the insert body 224 and the fixing groove 203 are interference fit to achieve a triple seal.

[0030] During installation, the gas supply connectors only require one bolt tightening after insertion to completely secure all gas supply connectors, greatly improving the efficiency of initial assembly and subsequent disassembly and maintenance.
