Abstract
UV/Fenton process was used as a pretreatment method to treat tetrahydrofuran wastewater.Experimental results showed that the influencing factors for the reaction mainly included pH,reaction time,the dosage of Fe2＋ and H2O2.Under the conditions of continuous aeration,the optimum reaction conditions of pH,dosage of Fe2＋,dosage of H2O2,reaction time were 5,2.5 mmol/L,12 mmol/L and 90 min,respectively.Under the optimum conditions,the removal rate of COD could be up to 85%.After treatment,the B/C value of the wastewater increased from 0.16 to 0.47,and the biodegradability was improved greatly,and the effluent could satisfy the requirements of follow-up biochemical treatment process compeletely.关键词
