<p>PROBLEM TO BE SOLVED: To provide a sewage cleaning device that makes use of a mobile contacting material capable of remarkably decomposing and cleaning the components of sewage. SOLUTION: In this sewage cleaning device which makes use of the mobile contacting material, characteristically, a porous material in which bacteria live is granulated, the granulated material thus obtained is added to the stream of water formed in an aeration tank, and then the components of the sewage are decomposed by the material moving in the tank. In addition, a small-sized container, which can exchange the stream of the water with the outside, is used as the aeration tank, and a cleaning engine mixes and stirs the porous material in the container. Furthermore, an outside aeration can additionally be combined.</p> |
