<p><P>PROBLEM TO BE SOLVED: To provide a treating method and an apparatus of organic wastewater enhancing a treatment capacity in a methane fermentation tank by multiplexing multiple indexes to use as a control index for controlling treatment of organic wastewater. <P>SOLUTION: Organic wastewater as a raw material is supplied to the membrane type methane fermentation tank 2 dipped with a membrane separation device 6 by a raw material supply means 1; a bacterial concentration (VS) and an activity of adenosinetriphosphate (ATP) in the membrane type methane fermentation tank 2, and a volatile organic acid concentration (VFA) in membrane permeated liquid having permeated through the membrane separation apparatus are measured; and a value of ATP/VS/VFA is found as a control index, to control a charge amount of the raw material by the raw material supply means 1 based on the control index. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
