Abstract

PURPOSE: To reduce the chromaticity and COD of treated water, by passing air or the like through a waste sulfide solution containing an organic substance to oxidize the waste solution until the reaction of sulfide vanishes and thereafter making the liquid acid by sulfuric acid and separating sulfur from the organic substance and oxidizing the solution again.
CONSTITUTION: Air or oxygen is blown into the waste sulfide solution containing the organic substance as in the manufacture of dye or medicine to oxidize the solution until the reaction of sulfide vanishes. The sulfuric acid is then added to the solution so that it becomes acid. The Thiosulfate in the waste solution is decompose and the sulfur produced is sedimented together with the colored organic substance. Sulfur dioxide is separated from the reaction system. The treated water is neutralized if desired and is supplied with air, oxygen or ozone for oxidation. As a result, the water solution disposal effect is raised and the treated water of about 400 mg/l in COD is obtained.
