Abstract

PURPOSE: To promote biological disposal and to ensure the adequate operation of solid-liquid separation, by combining a fluid bio-film method and a fixed bio-film method.
CONSTITUTION: Raw water flows into an aeration tank 2 from a raw water supply pipe 1. Granular solid 3, such as, sand, coke, etc. is suspended in the aeration tank, and suspension fluidized by the air lift action of air from an air dispersion pipe 5. After BOD and COD components in raw water are removed by microbes attached on the surfaces of granular solid, granular solid is separated at a granular solid sedimentation portion 6, and only bred microbes and SS in raw water are flown into a fixed bio-film tank 7. Minute SS in raw water is caught by the surfaces of bio- films attached to wall surfaces of nets 8, thus resulting in coarse SS. Bio-films exfoliate when they become not less than some thickness, flow into a sedimentation basin 10 through an outflow pipe 12 and a draft tube 13 and are sedimentation separated, and are changed into clarified disposal water and flow out from a disposed water outflow pipe 11.
