Abstract

This study is based on three raw plants in Fuyang,which are combined with double of three species of plants. In this study,6 plant groups,the watermifoil group,the hornwort Group,the Potamogeton pectinatus group,the watermifoil-Potamogeton pectinatus Group,the watermifoil-hornwort Group and the Potamogeton pectinatus-hornwort Group are constructed. Through the Restoration experiment of eutrophic water,the purification efficiency of six groups of plants is analyzed. The results show that all the 6 plant groups has good removal effects on the contaminated substances,the removal rate of ammonia nitrogen is over 95%,the removal rate of TN is over 75%,the removal rate of TP is over 47%,the removal rate of CODMn is more than 58%,the chlorophyll has some inhibitory effect. At the same time,by horizontal contrast,the plant assemblage has a better treatment effect on NH+ 4 -N,TN,TP and chlorophyll,and the treatment effect of CODMn is similar to that of the plant monomer. The AHP method is used to evaluate the combination of plant combination. The results show that the combination of the watermifoil -Potamogeton and pectinatus Group has the highest score,indicating that it has a good removal effect of pollutants in the whole process of water purification.
