植物修复技术在土壤重金属污染中的研究进展及应用

Research progress and application of phytoremediation technology in soil heavy metal pollution

近些年,由于农业及工业的大力发展,大量的废水、废气排入环境,导致土壤等的大面积污染。植物修复技术应运而生,且因适应性强、低投资、无二次污染等众多优点,该技术得到越来越多研究者的青睐。本文主要介绍了植物修复技术的分类、机理及优缺点,并介绍了其在土壤重金属污染重的研究进展及应用。

In recent years, due to the vigorous development of agriculture and industry, a large amount of waste water and exhaust gas have been discharged into the environment, leading to large area pollution of soil. Phytoremediation technology came into being, and because of strong adaptability, low investment, no secondary pollution and many other advantages, the technology has been more and more researchers of all ages. This paper mainly introduces the classification, mechanism and advantages and disadvantages of phytoremediation technology, and introduces its research progress and application of heavy metal pollution in soil.
