The preferred scheme is as follows:

preferably: the membrane support plate comprises a support plate and a breathable membrane, and the breathable membrane is thermally covered on the outer side wall of the support plate.

Through the technical scheme: the backup pad plays the effect of support, makes things convenient for the gas to pass through the ventilated membrane and give the microorganism oxygen suppliment of membrane outside treatment sewage.

Preferably: the supporting plate is formed by injection molding, and the supporting plate is made of engineering plastics.

Through the technical scheme: the backup pad is injection moulding, and when moulding plastics, put into a plurality of support ribs, it is fixed just to form when moulding plastics to guarantee a plurality of support ribs and backup pad.

Preferably: the side wall of the part of the air inlet pipe, which is positioned outside the mounting block, is provided with threads.

Through the technical scheme: the membrane support plate is conveniently connected with the threads through the threads, so that the membrane support plate is convenient to detach.

Preferably: the bottom of the installation block is arc-shaped concave.

Through the technical scheme: the bottom of the installation block is arc-shaped concave, so that the installation block can be conveniently fixed.

In summary, the utility model has the following beneficial effects:

1. through the arrangement of the petal-shaped membrane supporting plate, the contact process of the membrane element and sewage can be increased, microorganisms on the membrane surface of the membrane supporting plate are fully contacted with the sewage, and the effect of sewage removal efficiency is enhanced;

2. through the setting of a plurality of support ribs, can play the effect of reinforcing backup pad intensity.
