安徽某地浅层地下水"三氮"污染现状及运移模型构建
Status of the contamination of"three forms of nitrogen"in the shallow groundwater in an area in Anhui Province and their migration modeling
摘要
Abstract
In recent years,with the rapid development of industrialization and urbanization,industrial wastewater,domestic sewage and agricultural non-point source pollution have led to the increasingly prominent problem of the groundwater contamination by the"three forms of nitrogen".Based on flow field of the groundwater and concentration field of the"three forms of nitrogen"in the study area,this paper establishes a numerical model of groundwater flow,and analyzes the law of migration and transformation of the contaminants based on the convection and dispersion of groundwater.The results showed that NO3--N was highest in the total nitrogen content of groundwater,followed by NH4+-N and NO2--N.Groundwater convection and dispersion affect the velocity and scope of migration of the contaminants.The results of the study can help to reveal the migration and transformation laws of the"three forms of nitrogen"in groundwater,and provide strong support for the formulation of a scientific and rational governance program.关键词
