A pilot scale annular plug flow photoreactor with thin gap size, which combines with UV irradiation and hydrogen peroxide, was employed to deal with colored dyeing wastewater treatment. In the experiment, a mono-azo dye acid orange 10 was the target compound. The experimental parameters such as flow rate, hydrogen peroxide dosage, UV input power, pH and dye initial concentrations in a pilot scale photoreactor with flow rate of 9.32 m3day(-1) were investigated. Ultimately, the degradation rates were calculated and compared with a 100-l batch reactor. In our plug flow photoreactor design, the degradation rate of acid orange 10 was 233 times higher than that of 100-l annular batch reactor with same UV light source. The residence time needed for 99% decolorizing of 100 l of 20 mgl(-1) acid orange 10 wastewater was 26.9 min for the thin gap plug flow reactor and was far shorter than that of batch reactor needed.
采用一种具有窄间隙尺寸的中试规模环形活塞流光反应器,结合紫外线照射和过氧化氢来处理有色印染废水。实验中,单偶氮染料酸性橙10作为目标化合物。研究了中试规模光反应器中诸如流速、过氧化氢用量、紫外线输入功率、pH值和染料初始浓度等实验参数,该反应器流速为9.32立方米/天。最终,计算降解率并与100升间歇式反应器进行比较。在我们的活塞流光反应器设计中,酸性橙10的降解率比具有相同紫外线光源的100升环形间歇式反应器高233倍。对于20毫克/升酸性橙10废水,100升废水99%脱色所需的停留时间,窄间隙活塞流反应器为26.9分钟,远短于间歇式反应器所需时间。
