PURPOSE:To beforehand decomposition treat matter difficult to decompose by organisms treatment, by performing oxidizing agent treatment as a pre-process of organisms treatment. CONSTITUTION:The load of organisms treatment is lightened by oxidation decomposition treating organic waste water containing BOD, COD, chromaticity components, etc. by an oxidizing agent, and the removing rates of BOD, COD, chromaticity components, etc. are improved while indecomposable matter difficult to decompose by organisms treatment is beforehand oxidation decomposition treated. This method is particularly effective for treating waste water, which chromaticity is high and which COD is difficult to remove, such as, raw sewage, garbage furnace waste water, reclaimed land exuding waste water, etc. |
