室内空气中甲醛污染控制研究

摘要

Formaldehyde released by Interior decoration material and furniture is the characteristic pollutant of indoor air pollution.The methods of controlling indoor Formaldehyde pollution is studied in this paper,and the results shows that the concentration of Formaldehyde in the undecorated room is as the same as that in the outdoor air,the concentration of formaldehyde in the newly decorated rooms or the rooms have new furniture exceeds the allowed figure,and the more the rooms decorated the more serious the pollution is.The average amount of formaldehyde absorbed by activated charcoal is 5.83×10-3mg/ m3·g.The purification effect has relation with the existing time and the quantity of ozone.The removal rate between 1.07% to 40.49%.%室内装饰材料及家具等释放的甲醛成为室内空气污染的特征污染物。通过对室内空气中甲醛的污染控制方法的研究发现,未装修居室空气中甲醛浓度与室外甲醛浓度无显著性差异;新装修和有新家具的居室室内空气中甲醛超标,而且污染程度与装修程度正相关,装修程度越高,污染越严重。活性碳对甲醛的平均吸附量为：5.83×10-3mg/m3.g。臭氧对甲醛的净化效果取决于通入臭氧量的多少和与作用时间。实验条件下臭氧对甲醛去除率范围在1.07～40.49%。
