摘要: 研究了利用氧化铝生产排放的工业废渣拜耳法赤泥为主要原料制备水处理多孔陶粒滤料的方法。结果表明,在拜耳法赤泥、粉煤灰、河道底泥质量百分比为70∶20∶10,烧结温度为1 135 ℃,烧后自然冷却的条件下,制备的陶粒满足水处理用人工陶粒滤料的要求。将其用于含溶解油废水处理,在相同条件下,除油率约为砂粒的3倍。

Abstract: The preparation of porous ceramics with Red Mud derived from Bayer process as the main raw material for treatment of waste water in production of alumina was studied. The research indicated that the porous ceramics can meet demands of waste water treatment with the addition of Bayer red mud, fly ash and river sediments by mass ratio of 70%, 20% and 10%, after natural cooling from sintering temperature of 1135℃. If it is used in treating the oil-containing waste water, the oil removal rate is three times than that of sands at the same conditions.
