Abstract：Three kinds of aquatic plants, such as eichhornia crassipes, water hibiscus and commom duckweeds were used as water purification materials, and the purification effect of aquatic plants was studied with the treatment of water in university A in Zhengzhou. The results showed that the purification effects of three aquatic plants on COD in water were followed by eichhornia crassipes＞ water hibiscus＞ commom duckweeds; the purification effect of ammonia nitrogen was in the order of eichhornia crassipes＞ commom duckweeds＞water hibiscus; the purification effect of total phosphorus was in the order of water hibiscus＞ eichhornia crassipes＞ commom duckweeds. There was no obvious rule to the effect of pH value in water. Comprehensive comparison showed that eichhornia crassipes had a better purification effect on the synergistic removal of multiple pollutants in the landscape water.
