The simulation study on the purification law of nitrogen(N) in Deyeuxia angustifolia, Carex lasiocarpa and Deyeuxia angustifolia-Carex lasiocarpa combined wetland systems in the Sanjiang Plain, China was carried out by selecting three wetland units with different vegetation, in order to provide the theoretical basis for the study on the purification function of wetlands and the control of non-point source pollution in Northeast China. The results show that the above three types of wetlands can remove the total nitrogen (TN) in wastewater better, the maximum removal rate is over 90%, but there is no difference in the removal capacity of nitrogen in these wetlands. In the dynamic experiment the removal of N in different wetlands may mainly depend on adsorption process, not the absorption and utilization of plants. The retention capacity of N in Carex lasiocarpa wetland within 36 hours is the largest, about 62g, therefore Carex lasiocarpa wetland has much more practical application value.
