Abstract

PURPOSE: To treat the organic sludge at large digesting speed, with low energy consumption, by aerobically, biochemically treating the product of the anaerobic biochemical treatment for the erganic for the organic sludge, before separating into upper and lower phases, and then, by again biochemically treating the digested sludge being separated from the product of the former treatment together with the organic sludge.
CONSTITUTION: The organic sludge S1 is charged into the anaerobic reactor 1, and is anaerobically, biochemically treated for decomposing a part of sludge S1 into the low molecular weight compound. Next, without separating the liquid phase including the low molecular weight compound and the undecomposed sludge phase, the sludge S1 is charged into the aerobic reactor 2, to which air A blown for the aerobic biochemical reaction. That is, by this reaction, the low molecular weight organic compound is oxidizably decomposed into CO2, water, etc., and the organic sludge is partially oxidizably decomposed. Next, this treatment product is sent to the settling tank 3 and is separated into the supernatant liquid W and the digested sludge S2, and the supernatant liquid W is discharged. On the other hand, the greater part S3 of the sludge S2 is returned to the tank 1, and is again aerobically, biochemically treated together with the newly charged sludge S1, and the residual part is separately disposed as the disposable sludge S4.
