Based on analysis of nitrogen transfer process, indoor experiments of nitrogen sorption, adsorption and leaching are done to study on the migration and transformation pattern of nitrogen. The spatial and temporal variation of ammonium and nitrate in the soil column is got. The influencing factors of nitrogen migration and transformation are analyzed from the sources of waste and hydrogeologic conditions. Corresponding prevention and control methods of groundwater nitrogen pollution are put forward. |
