摘　　要：空气污染的指标有很多种类,其中一项比较常见的指标就是甲醛。去除甲醛时,不仅要考虑效果,还要考虑环保、节能和安全等因素,需要引起重视。对几种甲醛去除方法(自然通风法、活性炭吸附法、植物净化法及光催化氧化法)的效果进行对比分析,主要应用实验模拟的方法进行效果分析,首先应用玻璃仓模拟室内甲醛释放环境,在环境内分别应用上述甲醛去除方法,定期测量甲醛浓度,记录甲醛浓度数值,进行对比分析。经过实验发现,8h后不同玻璃仓内的甲醛浓度发生了明显的变化,甲醛去除率分别为 92.1%、68.4%、80%、50%。由此表明,持续的自然通风法更值得广泛应用,不仅具有良好的甲醛去除效果,并且节能、环保、安全,是有效的甲醛去除方法。There are many types of air pollution indicators,one of the more common indicators is formaldehyde.When removing formaldehyde,not only the effect must be considered,but also factors such as environmental protection,energy saving and safety must be considered,which requires attention.This article compares and analyzes the effects of several formaldehyde removal methods (natural ventilation,activated carbon adsorption,plant purification,and photocatalytic oxidation).The experimental simulation method is mainly used for effect analysis.First,the glass warehouse is used to simulate the indoor formaldehyde release environment.,Apply the above-mentioned formaldehyde removal methods in the environment,regularly measure the concentration of formaldehyde,record the value of the formaldehyde concentration,and conduct comparative analysis.It was found through experiments that the concentration of formaldehyde in different glass bins changed significantly after 8 hours,and the removal rates of formaldehyde were 92.1%,68.4%,80%,and 50%,respectively.This shows that the continuous natural ventilation method is more worthy of wide application.It not only has a good formaldehyde removal effect,but is also energy-saving,environmentally friendly,and safe.It is an effective formaldehyde removal method.
