系统介绍了赤泥的组成特性及其在土壤重金属污染治理和农业生产中的应用,为赤泥制备Cu2+、Zn2+、Cd2+、Pb2+等金属的吸附剂和赤泥基肥料提供了理论支持。同时,提出在开发利用过程中需对赤泥进行脱碱处理以避免其对环境的二次污染问题,实现赤泥零污染资源再利用。
This paper systematically introduced the characteristics of red mud composition,and red mud's application in remediation of heavy metal pollution and agricultural production.The rationale of red mud usage was provided for the red mud-based fertilizer and the adsorbents of Cu2+,Zn2+,Cd2+,Pb2+.The paper also put forward that alkali should be divorced from red mud before its exploitation in order to avoid secondary pollution to the environment and realize zero-pollution resources reutilization of red mud.
