<p><P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for treating waste water containing an organic high molecular substance utilizing a biological power generation technique, capable of efficiently decomposing the organic high molecular substance into a decomposed organic low molecular substance which is easier to treat. <P>SOLUTION: The waste water containing the organic high molecular substance 1 is stored in a raw water tank 2 and delivered by a pump to a decomposition tank 3, in which anaerobic microorganisms are incubated that can decompose the organic high molecular substance 1. Under a condition of pH controlled by a pH controller 8, the anaerobic microorganisms decompose the organic high molecular substance into a monosaccharide, an oligosaccharide, an amino acid, and a peptide, and further into a volatile organic acid, which results in forming treated waste water through decomposition. The treated waste water is delivered by a pump to an anaerobic area 5a in a biological power generation device 5, in which power is generated while solubilized organic substance is treated through decomposition via the reduction reaction by oxygen and the oxidation reaction by electrode-active microorganisms. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
