Experiment on Treating the Dying Wastewater with Blast-Furnace Ash and Fenton Reagent

Abstract:

The dyeing wastewater was treated via oxidation, coagulation and adsorption with Fenton reagent and blast-furnace ash. The removal efficiencies of colority and COD reached 90% and over 70% respectively.The proper process conditions were deter mined as follows: the pH of wastewater was 6, the dose of H₂O₂ was 40mL/L, the dose of FeSO₄ was 0.3moL/L, and the dose of ash was 40g/L, and the retention time was 20 min.
