摘要
针对南昌—莲塘地区由于工业污染及生活污水的排放造成浅层土体重金属离子含量远远超标的情况,以重金属离子迁移为研究对象,利用室内土柱试验对不同降雨量条件及在不同含水量条件下镉、锌离子在非饱和砂土中的迁移状况进行模拟,得到镉、锌离子在粘土中不同降雨量及不同时刻的迁移规律,对南昌地区重金属污染防治具有一定的参考意义。
Due to industrial pollution and sewage discharge in the district of Liantang, Nanchang, metal ion content of shallow soil exceeded greatly the standard. Aiming at migration of heavy metal ions, by using indoor soil column experiment, the paper simulates the migration of heavy metal ions in different water content and different rainfall conditions, obtaining its migrating laws. It has some reference value for the prevention of heavy metal pollution in Nanchang.
