【摘要】 在太阳光模拟灯的照射下,采用光-Fenton反应对废纸制浆废水进行了处理。结果表明,在Fenton试剂最佳物质的量比为10∶1、最佳pH值为2.8的条件下,光-Fenton反应处理废纸制浆废水效果显著,H2O2用量、催化剂种类和反应时间对TOC的去除也均有很大影响。在H2O2和Fe(Ⅱ)的用量分别为1883 mg/L和310 mg/L、pH值2.8及30℃的条件下,经过90min的处理,废水的TOC可去除66%以上。更多还原

【Abstract】 In this paper,the treatment of wastepaper pulping effluent by photo-Fenton was carried out under the irradiation of xenon.From this study,the photo-Fenton technology was proved to be highly effective for the treatment of such effluent.Up to 66% TOC removal can be achieved in only 90min of treatment by using 1883mg/L of H₂O₂ and 310mg/L of Fe（Ⅱ） at pH 2.8 and 30 ℃.The optimum Fenton reagent ratio and pH are 10∶1 and 2.8 respectively;dosage of H₂O₂,species of catalyzer and reaction time are also very important for TOC removal.更多还原
