<p><P>PROBLEM TO BE SOLVED: To provide an organic waste water treatment apparatus capable of solving the problem that sludge made by converting microorganisms contained in the sludge into a substrate increases a load to a biological treatment tank 2C, which causes a decrease in the sludge reducing efficiency or a deterioration in the quality of treated water, depending the state of the biological treatment tank 2C, and that much energy is required for the operation of the apparatus. <P>SOLUTION: The apparatus is characterized in that the sludge reducing efficiency is enhanced to the utmost, the quality of the treated water is properly maintained, and the apparatus can be miniaturized by directing attention to an efficient method for converting the microorganisms into the substrate in a circulation process comprising an ultrasonic device 7 and a supply tank 6 for crushing excess sludge. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
