Research on ecological restoration of micropolluted water by aquatic plants
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.
