Abstract

PURPOSE: To prevent clogging of a packing layer and stabilize treatment by dividing the inflow of air into a fixed-bed contact oxidation tank into the normal inflow of a head difference slightly larger than that of said oxidation tank and the temporary inflow of a head difference higher by specific times than that, and inserting the temporary inflow into the normal inflow.
CONSTITUTION: A distributor 2 is attached to the bottom part of a fixed-bed contact oxidation tank 1, and packings 4 are filled via a screen 3 in the upper part thereof. A blower 6 is connected to the distributor 2 via an air inflow pipe 7, and the air of a pressure slightly higher than the head difference of the tank 1 is supplied into the tank. Further, a compressor 10 is connected to the air inflow pipe 7 via a pressurized air storage tank 11 and the temporary inflow air having a pressure higher than at least 1.5 times that of the above-described normal inflow air and an air amount of more than 4 times is generated by the compressor 10. This is stored in the tank 11 and is supplied via the pipe 7 into the tank 1 through the distributor 2.
