水生植物修复污染水体研究现状及展望

Current Research Status and Future Prospects of Aquatic Plant Remediation of Polluted Waters

为了清除水体环境中的各种无机和有机污染物,净化污染水体,保护水环境,有必要对水生植物修复技术的研究现状进行归纳。利用各种在线搜索引擎,以“水生植物修复”为主题进行了文献检索。对检索结果进行了总结,重点关注水生植物修复的作用机制、影响因素、优势和局限性,以及未来研究的热点问题。结果表明:水生植物修复是一种清洁受污染水体的生态友好型优势技术。其机制包括植物挥发、植物降解、植物积累、植物固定和根系过滤等。水生植物在清除各种污染物方面发挥着特别积极的作用。在工程实践中,应根据所清除杂质的不同选择不同组合的水生植物物种以达到最佳的修复效果。指出了水生植物在清理水体污染物方面取得了巨大成功,但在修复技术的有效性和成功率方面仍存在一些限制。未来研究将深入探究水生植物的修复机制及影响因素以达到水生植物高效、可持续修复水体环境的目的。

In order to remove all kinds of inorganic and organic pollutants in water environment,purify polluted water and protect water environment,it is necessary to summarize the research status of aquatic phytoremediation technology.This paper conducted a literature search on the topic of"aquatic plant remediation"by using various online search engines.The results of the search were then studied and summarized,focusing on the mechanisms,factors,advantages and limitations of aquatic phytoremediation,as well as the hot issues for future research.Aquatic phytoremediation is an eco-friendly and advantageous technology for cleaning contaminated water.Its mechanisms include phytovolatilisation,phytodegradation,phytocumulation,phytofixation and root filtration.Aquatic plants play a particularly active role in removing various pollutants.In engineering practice,different combinations of aquatic plant species should be selected according to the impurities removed to achieve optimal restoration.Aquatic plants have been highly successful in cleaning up pollutants from water,but there are still some limitations in the effectiveness and success of remediation techniques.Future research will explore the mechanisms and factors affecting aquatic plant remediation in order to achieve efficient and sustainable remediation of water environments by aquatic plants.
