摘要
主要介绍了热处理方法对重金属污染土壤、底泥的修复和对其中存有的重金属的固定作用,论述了气氛、温度、时长、添加剂等因素对热处理修复、固定效果的影响,以及热处理后重金属形态/价态的变化。热处理受重金属污染土壤、底泥技术的未来发展应主要着眼于与其他修复方法联用、土壤和底泥的“再利用”、避免二次污染的处理综合工艺研究等方向。
The thermal treatment methods for the remediation of heavy metal contaminated soil and sediment or the fixation of heavy metals,the influencing factors on the remediation/fixation,such as atmosphere,temperature,duration and additives,and the speciation or valence change of heavy metals after thermal treatment,were summarized.In addition,a future research prospects regarding to the main research areas of thermal treatment technology for the contaminated soil and sediment was also proposed.These areas included combination with other remediation methods,the“reusing”of thermally treated soil and sediment,and the comprehensive treatment processes to avoid secondary pollution and so on.
