摘　　要：人有三分之一的时间是呆在自己的住房里面,而甲醛已经成为新房子里面对人体健康威胁较大的重要污染物。日常生活中,人们常用的净化甲醛方法是通风、种植观赏性植物、放置活性炭等。本文对比了这三种常用方法。结果表明,不同净化方法对甲醛的去除效率从高到低依次为通风>种植吊兰>活性炭吸附。然而在一年的净化过程后,部分房间的甲醛还是超标,因此建议三种方法协同进行,这样才能够提高甲醛净化效率。People almost spend a third of their life time in their own house, and formaldehyde has become one of the important pollutants which bring a great threat to human health in the new houses. In their daily lives, the commonly used formaldehyde purification methods are ventilation, cultivated ornamental plants, activated charcoal absorption, etc. This paper has compared the three methods. The results indicate that the removal efficiency order of different methods is ventilation, Chlorophytum comosum planting, and activated carbon absorption. However, formaldehyde concentrations in some rooms still exceed the standard after a year of the purification process. In order to improve the formaldehyde purification efficiency, it＆#39;s suggested to apply three methods collaboratively.
