【摘要】 赤泥用作环境修复材料具有成本低、工艺简单、以废治废的特点.系统介绍了赤泥对水体、土壤中重金属离子、有毒非金属离子、有机氯、染料颜料等无机、有机污染的环境修复作用.赤泥环境修复材料是附加值较高的赤泥开发产品,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污染,在对水体修复时应避免赤泥留在水中造成水体浑浊.更多还原

【Abstract】 Red mud,the by-product of aluminum manufacture, has a lot of alkali.Not only the water around the stack site, but also the landscape can be polluled by the stack of red mud.The red mud environmental remedy material has the characteristics of low cost, easy operation and waste recovery.The adsorption of red mud on heavy metal irons, toxic nonmetal ions, organochlorine and dye of water and soil is discussed.Environmental remediation material is a valuable product of red mud.When it is exploited,alkali should be divorced from red mud to avoid its pollution to the environment.It is necessary to avoid the red mud remain in and turbid water.更多还原
