摘要:
采用对流扩散方程并且考虑渗流作用的影响, 研究了缓流水体底泥污染物对周围土层的影响。发现污染物在土壤中的质 量浓度分布与渗流速度、作用时间、扩散系数等有关。作用时间越长, 扩散系数越大, 污染物影响范围越大, 质量浓度值越 高。渗流作用下污染物分布质量浓度有所减小, 但运移时间也减小。
Abstract:
This article studied the convection and diffusion of polluted materials in soil using convection and diffusion equation considering the effect of percolation .The results showed that the intensity distribution had relation with the velocity of percolation ,time , coefficient of convection and dif fusion .The longer time and the bigger convection and diffusion coefficient was , the bigger the polluted region .Under the function of percolation the intensity decreased , but the migrat ion velocity increased .
