A treatment method and apparatus capable of efficiently converting an organic polymer substance into a low-molecular-weight organic substance that is easier to process when treating a waste liquid containing an organic polymer substance using bioelectric power generation technology I will provide a. An organic polymer substance-containing waste liquid 1 is stored in a raw water storage tank 2, and a liquid feed pump is operated to send the organic polymer substance-containing waste liquid 1 to a low molecular weight tank 3. There are organic polymer-decomposing anaerobic microorganisms in the molecular weight reduction tank 3, and the organic polymer-decomposing anaerobic microorganisms convert the organic polymer into monosaccharides under pH conditions controlled by the pH controller 8. Decomposed into oligosaccharide, amino acid, and peptide, and further decomposed into volatile organic acid to form a low molecular weight processing solution. The liquid to be treated with a low molecular weight is supplied to the anaerobic region 5a of the bioelectric power generation device 5 by a liquid feed pump. In the bioelectric power generation device 5, the solubilized organic substance is decomposed while generating power by an oxidation reaction and an oxygen reduction reaction by an electrode active microorganism.
