Abstract

PURPOSE: To decrease washing frequency of filter bed, by supplying contaminated wate from the outer circumference part of cylindrical organism filter bed and flowing through the inner part of the filter bed and the, taking out from the central part, at the catalytic oxidation purification apparatus of the contaminated water utilizing purifying action of microorganism group.
CONSTITUTION: The circular or polygonal cylindrical water vessel 1 is used as organic contaminated water purifying apparatus of home life contaminatd water or food industry exhaust water etc. The water collecting vessel 5 is provided on the central part of the vessel 1 and the overflow dam 2 is provided on the outside of the vessel 1 at the highest part of outer circumference and the triangle dam 4 is provided for the sake of falling the contaminated water inside of the vessel uniformly. The contaminated water is flowed from outer circumference face of the organism filter bed 8 through the dam 2 and the dam 4 and next, is flowed through the bed 8 and at the same time, oxygen is supplied from the lower air distribution tube 6. The water is collected in the vessel 5 provided on the central part of the bed 8 after oxidizing and removing contaminated matter in the contaminated water by microorganism group stuck on the surface of the bed and then, is dicharged as treated water. Thus, multiplication of the microorganism is carried out uniformly and it is unnecessary to wash the bed frequently.
