中文摘要主要叙述TiO2/H2O2/UV和TiO2/O3/UV体系降解对氯苯甲酸(4-CBA)和喹啉的试验研究。研究表明,(1)在TiO2/H2O2/UV体系里目标物降解速度先随过氧化氢投加量的增加而提高,但超过一定浓度之后便开始下降;(2)在TiO2/O3/UV体系中,目标降解物的反应速度都非常快,且臭氧浓度高的时候降解速度更快;(3)二氧化钛催化剂在TiO2/O3/UV体系中作为积极因素有助于提高反应速率,而在TiO2/H2O2/UV体系是消极因素,会降低反应速率。; Two advanced oxidation processes, TiO_2/H_2O_2/UV and TiO_2/O_3/UV, were used in the chemical degradation of 4-CBA and quinoline in synthetic water with an initial concentration of about 100 mg/L. It was found that,(1) in the TiO_2/H_2O_2/UV system, the degradation rate of target substances was accelerated at low H_2O_2 concentration and reached the maximum at prime H_2O_2 concentration,however, the photo-catalytic degradation rate of target substance was decreased with the further increasing of H_2O_2 concentration;(2) in the TiO_2/O_3/UV system, it can be seen that 4-CBA and quinoline was degraded very quickly,and the degradation rate of target substances was enhanced with the increasing of O_3 concentration;(3) powder TiO_2 catalyst has a positive effect on production of hydroxyl radicals in TiO_2/O_3/UV system but negative effect in TiO_2/H_2O_2/UV system.; 国家“973”重点研究发展规划项目(G1999045711)
