[0002] Membrane separation is a separation process that uses a selectively permeable membrane as a separation medium. Under the action of a certain driving force on both sides of the membrane, a certain component in the raw material selectively passes through the membrane, thereby separating the mixture to achieve the purpose of purification, concentration, etc. Therefore, gas membrane separation technology has begun to be used in wastewater treatment, especially for the separation and treatment of harmful ammonia gas in wastewater to reduce damage to the environment.

[0003] The existing gaseous membrane separation device for wastewater deammonification still has some problems when in use. First, since the wastewater not only contains a large amount of harmful gases, but also some waste residues in industrial production are mixed in it, during the separation process, the existing gaseous membrane separation device needs to filter the wastewater through a filtering mechanism before deammonifying it. However, during long-term use, the filtering mechanism is prone to contamination and clogging, the filtering effect is reduced, and the waste residues are easy to stick to the inner wall of the membrane separation equipment body, which not only brings inconvenience to cleaning, but also reduces the separation effect of the device for wastewater deammonification. Secondly, the internal separation membrane of the traditional gaseous membrane separation device for wastewater deammonification needs to be replaced continuously by humans after use, which is time-consuming and labor-intensive, and increases the cost of use.
