Title:
METHOD AND SYSTEM FOR HYDROTHERMAL OXIDATION
Document Type and Number:
Japanese Patent JP2003175392
Kind Code:
A
Abstract:
To provide a method for hydrothermal oxidation for treating liquid containing a highly concentrated ions or salts.
In the method of hydrothermal oxidation, a to-be-treated liquid is filtered, and solid and suspended matters are removed in a step S1. The treated liquid is heated to a predetermined temperature, e.g. 40°C in order to improve efficiency of electrodialytic treatment in a step S2, and the liquid is subjected to the electrodialysis treatment to reduce as far as possible inorganic ions in the liquid containing organic substances in a step S3. In a step S4, dilute solution of the liquid is subjected to a supercritical-water oxidation treatment of one kind of hydrothermal oxidation treatment.
