关键词	Red Mud Sediment Resuspension Acidfication Control
摘要	The present paper mainly studies the adsorption properties of red mud on ammonian and phosphate as well as the control on sediment resuspension. The results show that, after acidfication, the removal rate of phosphate rose from 34.0% to 83.1% with the red mud concentration of 1 g/L. Furthermore, red mud can be quickly settled to the bottom, and calcium sulfate(CaS0(4)) generated by acidification react with tricalcium aluminate(3CaO center dot Al2O3) or activated calcium hydroxide and aluminum hydroxide in the red mud and generate cement bacillus(3CaO center dot Al2O3 center dot 3CaS0(4)), which can grow on the surface of red mud particles forming an isolation layer to inhibit sediment suspension.
