Abstract
An apparatus for biological treatment of water in which a water containing organic matter (e.g. waste water, recovered water, or untreated water in water treatment works) is biologically treated to decompose and remove the organic matter, which apparatus comprises a formed material comprising a felt-like activated carbon fiber cloth, accomodated in the treatment vessel as a packing medium, which has a ratio of surface area (cm.sup.2) of felt-like activated carbon fiber cloth to effective volume (cm.sup.3) of the treatment vessel, of 0.5-50 cm.sup.2 /cm.sup.3, and which is arranged so that the cloth surface is vertical and the cloth-to-cloth distance is 0.5-2.0 cm, thereby shortening the rise time from operation start to stable operation, and efficiently operating over a long period of time.
