室内植物对甲醛净化性能的研究进展

随着人们生活水平的提高，室内空气净化已成为人们普遍关心的问题，而甲醛作为室内空气污染的头号杀手，引起了人们的巨大关注。笔者简述室内甲醛污染的来源、危害以及净化甲醛的重要性。与物理吸附、化学吸收、光催化和生物降解等技术相比，植物净化甲醛技术具有自然、环保、操作简单的特点，已经成为室内甲醛净化和室内植物景观研究的热点和前沿科学之一。综述植物净化甲醛的国内外研究进展，着重从吸附净化、代谢净化及根际微生物的降解净化等3方面阐述植物净化甲醛的机理，介绍植物净化甲醛的毒理研究进展，同时指出目前研究中存在的主要问题，并进一步提出未来的研究发展方向。

Progress of Research on the Purification of Formaldehyde by Plants

Purification of indoor polluted air becomes a common concern topic along with living standards’ enhancement. As the top killer of indoor polluted air,the formaldehyde pollution was of special concern. The origin of formaldehyde and its enormous pollution in indoor air were inevitable,so it was very import to purify indoor air formaldehyde. Compared with technology of physical absorption,chemical absorption,photocatalytic biodegradable,the purification of formaldehyde by plant was natural,environmental and easy operate,which became the hot topic and advanced science in the research of purification of indoor formaldehyde and houseplant landscape. The domestic and abroad research progress of aerobic granular sludge was summerized. The theory of purification of formaldehyde was the absorption by the stem and foliage,the metabolism and transformation by the plant,and the degradation by the rhizosphere microorganism. Toxicological purification of formaldehyde by indoor plants was viewed. Advantages and disadvantages in research were reported,too. Finally,the foreground of the purification of formaldehyde by indoor plants was prospected.
