A process for the treatment of a waste liquid containing boron compounds and organic compounds, such as resulting from the oxidation of paraffins with oxygen in the presence of boron compounds, includes combusting the waste liquid in a furnace at a temperature higher than 1000 DEG C. in the presence of a large amount of steam. The combustion gas may be introduced into a heat recovery zone, preferably a boiler, to recover the heat thereof and then into a contacting vessel to bring same into contact with water and to recover the boron components contained in the gas. Since substantially all the boron components contained in the combustion gas are present in the form of gaseous metaboric acid, there is caused no deposition of boron oxide onto the interior walls of the combustion furnace or gas passages in the boiler. |
