Abstract

The present invention provides a technique which enables a reduction in the amount of discharged excess sludge in a method and apparatus for biologically treating organic waste water. An aspect of the present invention provides a method for treating organic waste water (1) in a biological treatment system (7,8) such that excess sludge is generated, which comprises treating the organic waste water by the biological treatment system (7,8), solubilizing obtained sludge and then returning the solubilized sludge to the biological treatment system (7,8), wherein sludge drawn from the biological treatment system is introduced into an acid fermentation tank (10), and the sludge in the acid fermentation tank (10) is introduced into an ultrasonic treatment apparatus (11) by means of a pump and pulverized by the ultrasonic treatment apparatus (11) and then circulated to the acid fermentation tank (10).
