Abstract
PURPOSE: To eliminate especially the COD effectively and with a low cost, by treating the organic waste water having the BOD/COD les than the prescribed value by passing the water through a solid state particle filled layer under the aerobic conditions in an adsorbing process of the fliud medium system under more aerobic conditions.
CONSTITUTION: The so-called secondary treated water obtained by treating the city waste water by the activated-sludge process put under an organism filtering process of the solid state particle filled layer system. Thus the BOD contained in a liquid is decomposed and removed as soon as possible under the aerobic conditions. At the same time, the SS is also removed effectively by the organism filtering function of the filter material. In this case, the BOD must be removed so as to set the BOD/COD ratio at ≤0.5. Then the secondary treated water with which the first treating process is put under the next adsorbing process to be completely mixed with a fluid medium composed of the glanular active carbon and/or zeolite, etc. and with the introduction of the air. After this process, the water is separated from the fluid medium. In such way, the COD can be effectively eliminated with a low cost.
