摘要
研究UV/Fenton试剂中各个因素对降解高浓度含酚废水的影响,确定UV/Fenton法处理高浓度含酚废水的最佳工艺条件。保持UV/Fenton体系的基准条件不变,通过改变pH值、H2O2浓度、Fe2+浓度、反应时间等实验条件,考察这些因素对UV/Fenton法处理高浓度含酚废水效果的影响。结果表明,UV/Fenton试剂对高浓度含酚废水有较好的去除效果和较高的反应速率。当苯酚初始浓度为1 000mg/L时,紫外光波长为253.7nm,反应时间为25～40min,pH值为6～7,H2O2浓度为40～50mmol/L,Fe2+浓度为28～30mg/L时,苯酚去除率可达90%以上,满足后续生物降解要求。
The paper studied the impact of various factors of UV/Fenton reagent on the degradation of wastewater containing highly concentrated phenol and determined the best technological conditions of water treatment.Keeping the basic reaction conditions of the UV/Fenton system constant,we investigated the influence of these factors on the effect of the treatment of wastewater containing highly concentrated phenol by changing the experimental conditions such as pH value,concentration of H2O2,concentration of Fe2＋and reaction time,etc.The experiment results show that the UV/Fenton reagent has a better removal effect and a higher reaction rate than the traditional methods.The removal rate of phenol is over 90% with the following conditions： initial phenol concentration of wastewater is 1 000 mg/L,UV wavelength is 253.7 nm,reaction time is 25-40 min,pH value is 6-7,the concentration of H2O2 and Fe2＋ are 40-50 mmol/L and 28-30 mg/L respectively,satisfying the requirements of follow-up biodegradation.
