摘要
赤泥是氧化铝生成过程中产生的工业废渣,对赤泥的综合利用一直是人们关注的焦点。在环境污染问题日趋严重的今天,赤泥在废水治理领域的应用也成为了一个重要的研究方向。赤泥用于水处理具有成本低、工艺简单、以废治废的特点。论述了赤泥作为吸附剂材料去除废水中的营养盐、F-等阴离子、重金属离子、砷等有毒非金属以及染料废水中的酸性和碱性染料的研究与应用现状,并介绍了利用赤泥为原料制备成复合型高分子无机絮凝剂用于水处理的研究情况,对其处理机理进行了分析,最后对赤泥在水处理方面的应用研究提出了展望。
Red mud （RM） is an industrial waste in production of alumina. Its comprehensive utilization is always the focus of attention. Application of RM in wastewater treatment has also become an important research direction with increasing serious environmental problems at present due to the characteristics of low cost,simple process,and ＇ waste control by waste＇ that RM applied in water treatment. Current research and application status of RM as an adsorbent in water treat- ment,sueh as removal of nutrient salts,anions like F ,heavy metal ions,and toxic nonmetals like arsenic,as well as removal of acidic and-basic dyes in dye wastewater was reviewed. Situation of research on RM as raw material for preparing composite inorganic polymer flocculant used in water treatment was also introduced. At last, mechanism of RM treating water was analyzed and prospect of future application and development of RM in wastewater treatment was discussed.
