摘要： PURPOSE:To allow the stable treatment even under high BOD volume load by further increasing the living thing sticking surface area of the conventional activated sludge treating device which is installed with assemblages of cylindrical bodies opened at both ends in order to increase the sticking area of microorganisms but has heretofore a limit in the living thing sticking quantity. CONSTITUTION:Cord-like filter media 12 are inserted into all the cylindrical bodies 11 exclusive of one or plural pieces of the cylindrical assemblages in an aeration tank. One or plural pieces of the cylindrical bodies 11a are used as air lift pipes to stick the microorganisms to the surfaces of the cylindrical bodies and the surface of the cord-like filter media, by which the treating capacity is improved. The cylindrical assemblages are more preferably bundled by cylindrical body binders 14 and the cord-like filter media are preferably formed to a spiral shape in order to increase the surface areas.

摘要： PURPOSE:To make it possible to save running cost even when amt. of air feeding is increased as the concn. of a waste water increases by feeding oxygen to microorganisms by air emission in an aeration tank wherein the waste water is cleaned by means of organism contacting oxidation method. CONSTITUTION:An aeration tank is constituted of tanks 11, 12...16 being provided in multi-stages and transferring of water between tanks are performed by overflow and an endlessly formed string-like contacting material 20 is circulated and is passed through water in each tank to perform aerobic organism treatment in each tank. Insufficiently treated water in the lowermost tank is returned to the uppermost, tank by means of a pump. In this apparatus, as the surface area of water is large and contact between water and air is sufficiently performed by overflow, an air diffuser is not needed.

摘要： PURPOSE:To reduce an installation space and to reduce initial cost by integrally constituting an aeration tank and a sedimentation section by providing the sedimentation section to the upper peripheral part of the aeration tank to allow the sedimentation section to communicate with the aeration tank and providing the trough receiving the supernatant water in the sedimentation section. CONSTITUTION:A sedimentation section 8 is arranged to the upper outer periphery of an aeration tank 1 and allowed to communicate with the aeration tank 1 at the lower part thereof through a plate 9 being a distribution plate permitting water to pass such as a perforated plate. This plate 9 plays a role for suppressing the water stream in the aeration tank 1 at the communication part. Further, a trough 10 is provided to the upper part of the sedimentation section 8 and an outflow pipe 11 is provided to the trough 10 and the supernatant water in the sedimentation section 8 flows to the trough 10 to be discharged from the outflow pipe 11. Since the sedimentation section 8 is integrally mounted along with the aeration tank, an installation space can be reduced and initial cost such as installation cost can be reduced to a large extent.
