36号(実公平7−11837号)に見られるように、
散気口が比較的粗目であるため目詰まりは起さないが、

あった。2. Description of the Related Art A conventional diffuser is disclosed in Japanese Utility Model Registration No. 20955, which was invented by the inventor of the present invention.
As seen in No. 36 (Jitsuho 7-11837),
Although the air opening is relatively coarse, no clogging occurs,
There is a drawback that the generated bubbles are too coarse. Also, only a porous diffuser made of PP or ceramics has fine bubbles and good oxygen efficiency, but has a drawback that clogging easily occurs.

である。According to the present invention, an air supply pipe is provided inside a porous cylinder having an appropriate size, and a head having a space formed at an outlet of the air supply pipe is provided. A float having a diameter larger than the diameter of the outlet is accommodated in the space of the head, and a closing part is provided at a part of the outlet of the head.

【発明の実施の形態】いま空気供給管から導入された外
気は送気管に入り、そのまま頭部の出口から周囲の多孔

へ送られるから、次第に浄化されるようになる。DETAILED DESCRIPTION OF THE INVENTION Now, outside air introduced from an air supply pipe enters an air supply pipe, and is continuously sent to the sewage tank as fine bubbles from the outlet of the head through the wall surface of the surrounding porous cylindrical body as it is. Then, it will be gradually purified.
【0006】また、送風機の運転停止時に汚水が多孔質
筒体内部に浸入し、送気管に逆流しようとしても、浮子

まい、汚水が逆流浸入することはない。Further, even if sewage infiltrates into the porous cylindrical body when the operation of the blower is stopped and tries to flow back into the air supply pipe, the float acts as a check valve, so that the outlet of the air supply pipe is sealed and the waste water is contaminated. Does not enter the backflow.
