On the Research of Environmental Mineral Material Preparation and Application

In the part of the paper, use bentonite as a basic material synthesis with phenolic aldehyde foam plastic. The experiment mainly researched into the capacity of the synthesis to purify and store rain water. The results show that, water absorption polymer phenolic aldehyde foam's addition to environmental mineral material can promote the capacity of purifying rain water greatly, with 10 percent of bentonite, the removal of BOD5 in the rain water can be promoted to 90 percent, COD's to 80 percent, during which the removal turbidity can be 83 percent. While use bentonite only, the removal rate of BOD5 can only be 62 percent, the removal rate of COD can be 20 percent, and the removal rate of turbidity can be 68 percent. So it depends on the local's pollution conditions to choose environment mineral material to purify the rain water effectively. When choosing bentonite as basic material to synthesis with phenolic aldehyde foam plastic, the polymer's water absorption rate and rate of water loss to rain water change with different proportion of bentonite. Through the purify rain water test with plants cultivated in environmental mineral material, purify layer and storage layer can meet all the requirements including the function of purifying and storing rain water, exhibit benefit of the synthesis polymer.
