摘要:
An object of the present invention is to provide a process and an apparatus for treating an aqueous medium at low running costs with a decreased electricity required for hydrothermal electrolytic reaction. The present invention proposes a two-step process comprising a first step of performing a conventional hydrothermal reaction or a conventional electrolytic reaction prior to hydrothermal electrolytic reaction to degrade readily degradable substances or ammonia or various electrolytically degradable organics and then a second step of performing hydrothermal electrolytic reaction to degrade the remaining organics, whereby the electricity consumed by hydrothermal electrolytic reaction in the second step can be greatly reduced.

An object of the present invention is to provide a hydrothermal electrolytic apparatus that allows a large amount of waste liquor to be efficiently treated. In order to attain this object, a hydrothermal electrolytic apparatus according to an aspect of the present invention comprises a reaction cell for electrolyzing influent at high temperature and high pressure wherein the overall surface area of a pair of electrodes located in the reaction cell 31 per 1 m of the volume of the influent is 0.05 m or more. A hydrothermal electrolytic apparatus according to one embodiment of the present invention has two or more tubular reaction cells each having a metal inner wall serving as a cathode and an anode is provided in each of said reaction cells. A hydrothermal electrolytic process according to another aspect of the present invention comprises incorporating conductive particles into the influent to substantially increase the surface area of electrodes in hydrothermal electrolysis.

An object of the present invention is to provide a process and an apparatus for treating a gas containing reducible substances to efficiently degrade and remove the reducible substances. As a means to achieve this object, the present invention provides a process for treating a gas containing reducible substances by hydrothermal electrolysis, comprising supplying a gas containing reducible substances into a reactor charged with an aqueous medium containing a halide ion under application of a direct current at a temperature of 100 DEG C or more but the critical temperature of said aqueous medium or less and at a pressure that allows said aqueous medium to be kept in the liquid phase.
