Experimental Research on Purification Capability of Different Media to the Water of Yitong River

Purification situation of different media to the corresponding polluted components in the downstream of Yitong River in Changchun is studied in this paper. The polluted water samples and different media which fit the dualistic structure of Yitong River are collected in the experiment. The soil columns are used in experiment to simulate the purification capability under nature conditions. According to series of soil samples analysis and water sample tests, the regularity of filtering purification capability patterns of different media to polluted water are got. The results provide scientific proof for predicting the development of groundwater pollution.
