| 摘 要： | 分析了FeSO4和H2O2的初始浓度及溶液pH值对UV/Fenton法降解四环素废水的影响.结果表明四环素的初始浓度为25,mg/L时,降解四环素的最佳工况:FeSO4的初始浓度为0.05mmol/L,H2O2的初始浓度为10,mmol/L,pH值为2.5,在反应时间为60,min时,对四环素的去除率可达93.14%.另外,对自然光、太阳光、紫外光三种不同光照条件进行了对比试验,得出紫外光辐照下的四环素去除率最高,太阳光次之,自然光最小.

| Abstract: | The influences of initial concentrations of the FeSO4, H2O2 and solution pH values on the degradation of tetracycline wastewater by UV/Fenton process were analyzed. Experimental results indicate that when the initial concentration of tetracycline was 25 mg/L, the optimum operational conditions of the processes were as follows： the initial concentration 0.05 mmol/L FeSO4, 10 mmol/L H2O2, pH2.5. After 60 minutes＇ reaction, the tetracycline removal rate was 93.14%. In addition, comparative tests on varous lighting conditions （natural daylight, sunlight and UV-light） were conducted. The results show that the tetracycline removal rate was highest under UV irradiation, a little lower under sufllight, lowest under natural daylight. |
