观赏植物净化室内空气中甲醛的研究进展

Researches in the removal of formaldehyde from indoor air by ornamental plant

根据室内空气中甲醛的污染现状及其对人体的危害性,列举了甲醛的治理技术,综述了国内外观赏植物净化室内空气中甲醛的研究进展。观赏植物对甲醛的去除途径主要是通过茎叶吸收、植物代谢与转化以及根际微生物的降解作用等。在植物根际添加微生物营养型吸附基质或者在植物叶面喷洒二氧化钛溶胶以及在植物叶际、根际接种微生物等方式将会强化甲醛的去除效果。

Formaldehyde pollution in indoor air, its harm to human health and control of formaldehyde by ornamental plant were reviewed. The approach for removal of formaldehyde was the absorption by the stem and foliage, the metabolism and transformation by the plant, and the degradation by the rhizosphere microorganism. Adding microorganism nutritious substrate in the rhizosphere, spraying TiO2 sol on the foliage or inoculating microorganism in the rhizosphere and the foliage would enhance the removal of formaldehyde from the indoor air.
