成都粘土中特征污染因子的迁移规律和铅、铬的污染预测

STUDY ON THE CHARACTERISTIC CONTAMINANT MIGRATION BEHAVIORS AND Pb^2+, Cr^6+ CONTAMINATION PREDICTING OF CHENGDU CLAY

论文以模拟淋滤实验和压榨实验为基础，系统分析了成都粘土中特征污染因子的吸附迁移规律，初步计算了成都粘土对Ｐｂ２＋、Ｃｒ６＋等重金属的环境容量并预测了若干年后它们在成都粘土中的累积状况。

Based on the data of leaching test and pour water extraction test by pressure,in this paper the absorption and migration behaviors of some characteristic contaminants are discussed and the environmental capacity of Chengdu Clay,related to some heavy metals such as Pb^2+ and Cr^6+,is calculated,and their accumulating levels in a certain number of years in the clay are predicted.
