Abstract

PURPOSE: To eliminate the blockade of a filter bed, by exfoliating microbe groups by self-digestion action without depending upon forced washing and the exchange of filter beds by alternatively flowing down organic sanitary sewage from both ends of a water passage of a treatment tank in a condition that a fixed period is set.
CONSTITUTION: Organic sanitary sewage, such as, sanitary sewage dining rooms, etc. is let frow down in the direction to 2 from 1 in a long water-passage of a catalytic oxidation tank 7, and air is fed to an air splinkling pipe 12 from a blower 13. When continueing operation, an inflow portion in the catalytic oxidation tank 7 is mainly changed into an anaerobic condition, and a filter bed is blocked. Here, when changing a flow path of sanitary sewage in the reverse direction of 4 from 3, microbe groups attaching to the filter bed and the space of the filter bed are exfoliated, self-digestion is produced and the microbe groups are caught in a treated water tank 6. If a filter bed, to which anthracite is filled, is beforehand inserted into the treated water tank 6, the excellent qualtity of treated water can be obtained. This method eliminates the blockade of the filter bed.
