Apparatus for biological treatment of water and waste, of the attached- growth type

摘要

An apparatus for biological treatment of water and waste of the attached-growth type, constructed by disposing long fiber bundles formed by binding a large number of monofilaments, upward and downward in a zigzag formation in a vessel, fixing substantially the upper and lower angle portions thereof, and particularly incorporating supports for supporting the angle portions of the long fiber bundles disposed upward and downward in a zigzag formation, into a part of a frame assembled in advance together with frame members, the apparatus being capable of high- volume treatment, causing little clogging, lowering construction costs, and capable of stable long-term operation.
