摘要
系统总结不同水生植物对河流等微污染水体生态修复效率,阐述水生植物修复水体的净化机制并分析水生植物在净化过程中的影响因素(温度、透明度、污染物浓度)及其互相作用机制,结果显示挺水植物对Hg、Fe、Cu、Zn 等污染物的去除率分别为 32.6％～39.7％,44.9％～51.4％,63.7％～70.5％,74.7％～79.4％,沉水植物对 Co、Ni、Cu、Zn 的去除率分别为 44.7％～45.3％,55.7％～59.3％,64.8％～69.4％,61.3％～65.4％.可为生态修复工程中水生植物的优选工作提供理论基础.
Abstract
This paper systematically summarizes the ecological restoration efficiency of different aquatic plants on slightly polluted water bodies,such as rivers.Explain the purification mechanism of aquatic plant restoration water body and analyze the influencing factors(temperature,transparency,pollutant con-centration)and the interaction mechanism of aquatic plants in the purification process.The results showed that the pollutant removal rate ofHg,Fe,Cu and Zn were 32.6％～39.7％,44.9％～51.4％,63.7％～70.5％,74.7％～79.4％,respectively.The removal rate of Co,Ni,Cu,and Zn were 44.7％～45.3％,55.7％～59.3％,64.8％～69.4％,and 61.3％～65.4％,respectively.This paper can provide a theo-retical basis for the preferred work of aquatic plants in ecological restoration projects.
