植物在环境污染治理中有很大的潜力。本文介绍了植物整治的一般原理,综述了其在去除Cd2 + ,Pb2+ ,Hg ,Ni2 + 等金属离子,富营养水体中的N、P 元素、有机废水治理中的研究现状,以及植物回收贵重金属的可能性。讨论了今后的研究方向:一是植物对重金属及其它污染物的耐受及解毒原理;二是选育高年生物量、耐受性强、根系发达的“超级植物”;三是优化工艺,提高综合效益
Plants have great potential in environmental pollution control. In this paper, the general principles of plant remediation are introduced. The current research status of organic wastewater treatment in removing Cd, Pb2 +, Hg, Ni2 + and other metal ions and N, P elements in eutrophic water is reviewed. The possibility of. The future research directions are discussed: one is the plant’s tolerance to heavy metals and other pollutants and the principle of detoxification; the other is the selection of “super plants” with high annual biomass, strong tolerance and developed roots; thirdly, the optimization process, Improve overall efficiency
