<p><P>PROBLEM TO BE SOLVED: To provide a new treating method for organic wastewater, which remarkably reduces the amount of excess sludge produced during a biotreatment on the organic wastewater. <P>SOLUTION: According to the treating method, the sludge produced during the biotreatment on the organic wastewater is solubilized in a solubilizing reaction treatment tank, and a gas is mixed into a solubilized liquid, which is then filtered via a membrane filtration device. A resulted membrane filtered liquid is biotreated in a bioreaction tank, while a membrane concentrated liquid is returned to the solubilizing reaction treatment tank. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
