Study on Radioactive Organic Wastewater Treatment by Fenton Reagent

Abstract:

The radioactive organics in wastewater were removed by Fenton reagent. The optimum conditions determined by single-factor test and orthogonal experiment are as following: [H₂O₂] =1.0mol·L^-1, [Fe²⁺] =6.00mmol·L^-1 and 30min at pH=4.0. Under these conditions, the COD removal efficiency was 81%. The dosage of Fe²⁺ was the most influential factor on organic wastewater COD removal by Fenton and the following influential factors were the reaction time, H₂O₂ dosage and pH value. In the process of radioactive wastewater treatment by Fenton, the effect of molten iron complexes flocculation was bigger than hydroxyl radical oxidation on COD removal.
