平果铝业公司赤泥的土壤改良

Soil Amelioration of Red Mud in Pingguo Aluminum Industrial Corporation

在分析拜耳法赤泥理化性质的基础上 ,研究广西平果铝堆场赤泥的土壤改良与种植。结果表明 ,有机与无机混合体改良剂对赤泥土壤改良效果良好 ,使固废物赤泥变成植物能够正常生长的基质 ,氟石膏的加量起重要作用。无机土壤改良剂虽然基本上满足了植物生长的条件 ,但对赤泥的土壤改良效果不理想。

Based on the physical and chemical properties analysis of red mud from Bayer-process, the soil amelioration and planting on red mud in the storage yard of Pingguo Aluminum Industrial Corporation is investigated in laboratory. The excellent results are achieved in mud amelioration by use of organic and inorganic mixture, the red mud, solid wastes, becomes the base for plant normally growth. The gypsum plays an important role in the amelioration. Even though the basic condition for plant growth is satisfied by use of the inorganic amelioration scheme, the results are not ideal.
