PURPOSE:To efficiently decompose H2O2 within a short time by a small amount of a treatment agent and to suppress the concn. of the total solid in treated water to a lower level, by a method wherein the ground liver tissue of an animal or the extract thereof is added to and mixed with waste water containing hydrogen peroxide. CONSTITUTION:The ground liver tissue of an animal or the extract thereof added to and mixed with waste water acts as an H2O2 decomposing catalyst and, for example, even if small quantity of about 100mg/l is added to waste water containing 3,000ppm of H2O2 as liver tissue, H2O2 can be decomposed within a short time. The final total solid substance in treated water comes to an extremely low value of about 100mg/l. As a liver tissue to be used, ones of domestic animals such as a cow, a horse or a pig and poultries such as chicken are suitable.
