摘要
砷污染已严重影响重金属生产加工行业的发展,我国现存传统水泥固砷技术的处置率低、成本高,水泥生产过程中伴随大量砷污染等问题,因此应加强固砷方面的研究。在现存技术方面,矿渣胶凝固化技术相比于传统水泥固化技术具有高效、低污染、处理原料来源方便、适用面广等优点,是目前比较适宜推广和研究的一项技术。主要围绕碱激发胶凝材料对砷的固化/稳定化技术及固砷机理进行阐述。
Arsenic pollution has seriously affected the development trend of metal production and processing industry,the existing traditional cement arsenic fixation technology in China has low disposal rate and high cost,as a result,there is a large amount of arsenic pollution in the cement production process,therefore the research on arsenic fixation should be strengthened.Generally speaking,compared with the traditional cement curing technology,slag cementitious solidification technology has many advantages,such as high efficiency,low pollution,convenient source of raw materials,wide application and so on,which is more suitable to be popularized and studied at present.It mainly focuses on the arsenic curing/stabilization technology and the mechanism of arsenic fixation by alkali-activated cementitious materials.
