Outline
In order to study the effects of plants on the migration and accumulation of nitrogen in the biological retention system, and promote the vegetation construction of rainwater biological retention system in loess distribution area, 5 groups of biological retention system simulation devices were constructed by selecting Iris, Hemerocallis, Sedum, Ophiopogon and non-plants. The migration of nitrogen in fillers and the accumulation of nitrogen in each medium under different plant treatments were investigated. The results show that there was a close relationship between plant nitrogen accumulation and plant biomass increase during the experiment, which was as follows: Sedum> Iris>Hemerocallis> Ophiopogon. The nitrogen absorbed by plants was mainly accumulated in the upper structure of plants. The distribution difference of in the five groups of biological retention system fillers is not significant and the content of is low. is mainly removed in the upper part of the packing layer by adsorption, and each system has a good removal effect on . Plants have a significant effect on the distribution of in the packing and the migration of in the system. Compared with the non-plant group, the system with plants can reduce content in the filler, and the lower the content in the filler before influent, the lower the effluent concentration. The average TN removal rates of 5 treatments were as follows: Iris (50.59%)> Sedum (43.99%)> Hemerocallis (37.85%) Ophiopogon > (30.51%)> non-plant (26.09%).
