| Zusammenfassung: | PURPOSE:To remove muddy materials such as SS, BOD and COD in waste water easily and surely, by treating waste water such as dirty water generated in construction work by sulfuric acid or the hydrochloric acid aqueous solution both are dissolved with inorganic flocculant. CONSTITUTION:The aqueous solution where the in organic flocculant such as ferrous sulfate and aluminium sulfate is dissolved in sulfuric acid or hydrochloric acid is added to waste water such as dirty water generated in construction work. Then, SS components, BOD and COD in waste water are decomposed due to acid and are caused to cohere simultaneously. Thus, various muddy materials in waste water are removed easily and surely to treat waset water. |
