摘要: 针对室内挥发性有机化合物（VOCs），搭建了带风道式反应器的模拟环境舱实验系统，选取甲醛、甲苯和苯为目标污染物，研究了光催化对各污染物的降解性能及其之间的相互影响。通过装置的优化，还对紫外光下目标VOC降解的主要副产物进行了检测。结果表明，单组分VOC的降解实验中，该净化器对3种污染物均具有良好的降解效果，其中对甲苯和苯的降解性能相似，对甲醛的降解性能更优。2组分VOCs降解实验中，目标组分会受到另一组分的不同程度影响；甲苯和苯无论是作为影响组分还是目标组分其实验结果均较接近；甲醛对甲苯、苯的降解影响明显大于两者的相互影响，即甲醛对两者的降解反应阻碍更大。甲苯的主要副产物为苯、苯甲醛和苯甲酸，苯的主要副产物为苯酚。

Abstract: In this research, an experimental system was designed for the removal of indoor VOCs. The system was composed of a duct photocatalytic reactor and an environmental chamber. The target contaminants selected for the experiments were formaldehyde, toluene, and benzene. The experimental process was optimized reasonably by analyzing the degradation performance of each VOC and the reciprocal influence of other VOCs. Intermediates of the VOCs were tested at the same time. The experimental results for the three kinds of VOCs revealed that the duct photocatalytic reactor effectively degraded single-component VOCs. The degradation performance of toluene and benzene was similarly high, while the formaldehyde result was better. The target component could be influenced by the other two components during VOC degradation. The impacts of toluene and benzene on formaldehyde were similar, but the interactions between toluene and benzene were different from the influence formaldehyde had on them, during which the inhibition of formaldehyde was more significant. Benzaldehyde and benzene were primary intermediates of the toluene reaction, and phenol was the major intermediate in benzene degradation.
