The artificial floating bed reduces the nitrogen, phosphorus and organic pollutants in the water by the absorption of the roots of the plants, thereby purifying the biological control of water quality. In this paper, by using four different concentrations of contaminated water samples, the static test of Ipomoea aquatica. was carried out on a floating bed. The growth characteristics and main water quality indexes of the plants were measured at intervals of 10 days. The experimental period was 60 days, and the amaranth was quantitatively analyzed. The purification law of TN in water samples with different concentrations was analyzed, and the dynamic changes of nutrients in different tested water samples were analyzed, and the purification equation was constructed. The results showed that the floating bed cultivation of leek can absorb, adsorb and degrade the nitrogen in the water sample, carry out metabolic activities, and synthesize the substances needed by itself, which is closely related to the growth, and the TN concentration and the growth time of the plant are significantly negative.
