摘　　要：甲醛作为一种常见的室内空气污染物,会对人体健康构成严重威胁,因而对其进行脱除显得尤为必要。综述了国内外净化室内甲醛技术的研究进展,对不同方法存在的优缺点进行简要阐述。物理法具有操作简单、成本低廉的优点,广泛应用于室内甲醛的净化,但是存在处理效果不佳和二次污染的风险。生物法安全无污染,该方法作用速率缓慢,受环境因素影响较大,在一定程度上限制了生物法的应用。化学法能有效克服物理法和生物法存在的缺点,还具有吸附剂易于再生及产物易于回收等优点,在净化室内甲醛方面具有较为广阔的应用前景。Formaldehyde,a common indoor air pollution,is a serious threat to human health,so it is necessary to remove formaldehyde.The research progress of removal technologies of formaldehyde at home and abroad are summarized,and the advantages and disadvantages of different methods are discussed.The physical method has the advantages of simple operation and low cost,so it is widely used in the purification of indoor formaldehyde.However,there is a risk of poor treatment effect for secondary pollution.The biological method is safe and pollution-free.It is slow and greatly influenced by environmental factors to some extent so as to limit its application.The chemical method can effectively overcome the disadvantages of the physical and biological methods,which also has the advantages of easy regeneration of adsorbent and easy recycle of product,therefore,it has a wide application prospect in purifying indoor formaldehyde.
