<p>PROBLEM TO BE SOLVED: To provide a method for stably and efficiently treating, anaerobically together with an organic effluent, a liquid matrix obtained by liquefying, in a high efficiency, a solid biomass via a hydrothermal reaction by using an organic acid-containing liquid in place of water based on the permeation of both through an anaerobic treatment apparatus.SOLUTION: The provided anaerobic treatment method of an organic effluent targeting an effluent treatment apparatus including an acid generation tank and an anaerobic reaction tank is furnished with the following steps: a step of introducing, together with a solid biomass, a portion of an organic acid-containing liquid obtained as an effluent from the acid generation tank into a hydrothermal treatment apparatus and then obtaining a liquid matrix by liquefying both via a hydrothermal reaction under subcritical water conditions; and a step of returning the obtained liquid matrix into the acid generation tank, whereas the solid biomass and the organic effluent are anaerobically treated within the identical anaerobic reaction tank; an effluent treatment apparatus for implementing this method is also provided.</p> |
