ABSTRACT:
An activated sludge treatment method of waste water which comprises (a) the step of micronizing as far as possible the sludge in the waste water containing the BOD component to a degree not to have the cells of the microorganisms therein broken or destroyed and adsorbing the BOD component to the micronized sludge, and (b) the step of oxidizing the BOD component adsorbed to the sludge by blowing in an oxygen-containing gas and flocculating the sludge. By this method, the treatment of waste water is accomplished with a shortened residence time of the waste water in an installation for the treatment and with the production of excess sludge in a considerably reduced amount.
