水葫芦处理高氨氮废水的植物修复技术研究进展

Research Progress on Phytoremediation Technology of Eichhornia crassipes for Treatment of High Ammonia Nitrogen Wastewater

水体富营养化是一个迫切需要关注的全球性问题。氨氮存在于生活污水和工业废水中,是造成水体富营养化的主要因素之一。在最终排放之前,有必要将氨氮减少到相关标准的允许水平。植物修复具有经济、环保和可持续发展的特点,已被推荐为处理高氨氮废水的替代方法。水葫芦是一种自由漂浮的大型植物,被称为世界上最毒的杂草,具有生长速度快、环境适应性强、营养吸收能力高等特点,这些能力有助于水葫芦在植物修复方面的广泛应用。本文综述了植物修复技术的优势和局限,分析了利用水葫芦处理高氨氮废水的植物修复技术发展思路。

Eutrophication of water bodies is a global issue that requires urgent attention.Ammonia nitrogen exists in domestic sewage and industrial wastewater,which is one of the main factors that cause water eutrophication.Before final discharge,it is necessary to reduce ammonia nitrogen to the allowable level of relevant standards.Phytoremediation is economical,environmentally friendly,and sustainable,and has been recommended as an alternative method for treating wastewater with high ammonia nitrogen.Eichhornia crassipes is a large free-floating plant known as the most poisonous weed in the world,it has the characteristics of fast growth rate,strong environmental adaptability and high nutrient absorption capacity,which are helpful for the wide application of Eichhornia crassipes in phytoremediation.This paper reviews the advantages and limitations of phytoremediation technology,and analyzes the development ideas of phytoremediation technology using Eichhornia crassipes to treat high ammonia nitrogen wastewater.
