Study on the Pretreatment of LAS Wastewater by UV/Fenton Oxidation Technology
Abstract. Fenton and UV/Fenton oxidation technology were used to treat LAS wastewater. Experimental results showed that in the conditions of pH=6.0、Fe2+=7mM、H2O2/Fe2+=10:1, LAS removal efficiency was higher. Under the same conditions, for the removal efficiency of LAS and COD, UV/Fenton method is higher than Fenton method. After the treatment of UV/Fenton, the B/C value of raw water increased from 0.28 to 0.49, and can meet the requirements of biological process as followed.
