Summary:To provide a liquid treatment method and a liquid treatment device that can treat a refractory substance contained in a liquid of interest and degrade it into carbon dioxide and water, with higher energy efficiency than in the treatment only by electrolysis, and without causing harmful intermediate products.SOLUTION: The present invention discloses a liquid treatment method for degrading a refractory substance contained in a liquid of interest. The method includes an electrolysis step for electrolyzing the liquid of interest while injecting a gas containing at least oxygen into the liquid of interest.SELECTED DRAWING: Figure 2 【課題】処理対象液中に含まれる難分解性物質を二酸化炭素及び水に分解する際に、電気分解のみを行うよりもエネルギー効率が高く、かつ、有害な中間生成物を生じずに難分解性物質を処理することができる液処理方法及び液処理装置の提供。【解決手段】難分解性物質を含む処理対象液の前記難分解性物質を分解する液処理方法であって、前記処理対象液を電気分解するときに、前記処理対象液中に少なくとも酸素を含む気体を曝気する電気分解工程を有する液処理方法である。【選択図】図２
