[0026] See Figure 1 - Figure 2As shown in the figure, the anoxic membrane cleaning mechanism described in this embodiment includes a cleaning tank 1 and a compressed air unit 2. The cleaning tank 1 has a receiving cavity 11, which is sized to match the size of the anoxic membrane to be cleaned. And a cleaning liquid is filled in the receiving cavity 11. The compressed air unit 2 is provided with an air storage tank 21, an air inlet pipe 22 and an air outlet pipe 23. The air inlet pipe 22 and the air outlet pipe 23 are respectively connected to the air storage tank 21, and the air outlet pipe 23 is also hermetically connected to the inlet end of the anoxic membrane to be cleaned, so as to send compressed air into the anoxic membrane to be cleaned for oscillating cleaning.

[0027] The structure of this embodiment is simple and reasonably designed. By setting the cleaning tank 1 and the compressed air unit 2, when cleaning the anoxic membrane, while soaking and cleaning, compressed air enters the inside of the anoxic membrane to form an oscillating force and generate a backwashing effect, so that the dirt adsorbed on the membrane filaments can be quickly cleaned, thus achieving efficient cleaning.

[0028] Specifically, the cleaning liquid in this embodiment is the 8% sodium hypochlorite solution (or citric acid solution) used in the prior art. During the cleaning process, the dirt adsorbed on the anoxic membrane is soaked and diluted, and compressed air enters the anoxic membrane. The airflow forms an oscillating effect inside the anoxic membrane to generate a backwashing effect, thereby producing a "boiling" phenomenon in the diluted solution, so that the dirt adsorbed on the membrane filaments quickly detaches from the anoxic membrane, and the membrane is quickly cleaned, effectively solving the problem of substandard purification ability.

[0029] In some embodiments, a ball valve 24 is installed on the air inlet pipe 22.

[0030] In this embodiment, by setting the ball valve 24 and adjusting based on the opening degree of the ball valve 24, the air flow rate entering the anoxic membrane is controlled, so as to adjust the oscillating force during the cleaning process and achieve a better cleaning effect.

[0031] In some embodiments, the air inlet pipe 22 and the air outlet pipe 23 are respectively provided as steel pipes.

[0032] In this embodiment, by respectively setting the air inlet pipe 22 and the air outlet pipe 23 as steel pipes, the structure is simple, the service strength is high, and it is convenient to adjust and use the compressed air flow rate.

[0033] In some embodiments, the air outlet pipe 23 is hermetically connected to the inlet end of the anoxic membrane to be cleaned through a rubber hose 25.

[0034] In this embodiment, the connection through the rubber hose 25 has flexibility and is convenient for operation and use.

[0035] In some embodiments, the air outlet pipe 23 is provided with at least one group, and one group of the air outlet pipes 23 is hermetically connected to both ends of the inlet of the anoxic membrane to be cleaned.

[0036] In this embodiment, multiple groups of air outlet pipes 23 can be set based on the cleaning requirements, so as to clean multiple anoxic membranes synchronously. Here, it can be flexibly set according to the cleaning needs.

[0037] In some embodiments, a on-off control valve is provided on the air outlet pipe 23.

[0038] In this embodiment, the on-off control valve (not shown in the drawings) is mainly for the case where multiple groups of air outlet pipes 23 are set, and when some of them are not in use, they are closed, and the on-off control valve on the air outlet pipe 23 used for cleaning is in the open state to allow air flow through.

[0039] In some embodiments, the cleaning tank 1 and the gas storage tank 21 are respectively made by welding steel plates.

[0040] In this embodiment, by using steel plates to weld the cleaning tank 1 and the gas storage tank 21, the structure is simple, the firmness is good, and it is durable.

[0041] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
