新装修房屋甲醛释放规律及防治方法研究

Study on Change of the Formaldehyde Concentration of Newly Decorated House and the Formaldehyde Treatment Methods

为探明甲醛防治常用方法的有效性,通过测定新装修房屋室内甲醛浓度,探讨其一个月内的变化规律。并对通风换气、植物吸收、活性炭吸附、光触媒等甲醛防治常用方法效果进行对比。结果显示,新装修房屋一个月内甲醛浓度无明显下降规律。短期内,活性炭、光触媒、绿萝等均无法有效降低室内甲醛浓度。而通风换气15分钟后,在不关窗的条件下室内甲醛浓度才能够达标。

To verify the effectiveness of the common formaldehyde treatment,formaldehyde concentration of a newly decorated house was measured,and the change of the concentration was discussed.The effectiveness of the common formaldehyde treatment such as ventilation,plant uptake,activated carbon adsorption,and photocatalyst were compared.The results showed that formaldehyde concentration of a newly decorated house in a month decreased not significantly.In a short time,activated carbon,photocatalyst,scindapsus aureus were both ineffective for formaldehyde.The formaldehyde concentration could steadily reach the standard after ventilation for more than 15 min.
