利用拜耳法赤泥等固体废弃物制备水处理多孔陶粒滤料试验研究

:In this paper,Preparing method of production porous ceramics for treatment of waste water with Red Mud derived from Bayer process as the main raw materia of production of alumina were study.The research indicated that the porous ceramics of production meet demands of waste water filtration material when 70% of Red Mud derived from Bayer process and 20% of fly ash and 10% of river course sediments are added,1135℃of sintering temperature,natural cooling after sinter.the remove oil rate of porous ceramics are three times than Sands for the treatment of waste water contained oil at the conditions of same.
