Abstract

PURPOSE: To accomplish efficient removal of thick coloring components in a fermentative waste water, such as media for antibiotic substances, which was previously regarded as hard to decompose or remove.
CONSTITUTION: A mineral acid such a sulfuric acid is added to a ferementative waste water containing organic pollutants to control the pH thereof to 1 to 4. After the removal of the resulting precipitates, slaked lime is added to the remaining waste water to control the pH thereof to 10 to 13. Subsequently, the resulting precipitates are removed.
