摘要
介绍了国内外锯末、改性锯末、锯末制备活性炭在水处理研究的进展现状,分析了吸附机理、影响因素等。锯末作为林产品重要的废弃物之一,具有来源广、价格低、可再生等特点;其内部的骨架结构材料比表面积大且富含羟基、羰基、羧基等活性官能团,易改性,吸附效果良好,已被广泛的应用于水处理研究中。对未来的研究方向进行了展望,认为寻找性能优良或对某种污染物有特别的吸附效果的制锯末树种,扩大产业化应用规模,锯末最终无害化处理,以及吸附剂的水力学、热力学、动力学特征研究等应进一步加强。
Reported at home and abroad sawdust, modified sawdust, sawdust preparation of activated carbon water treatment research progress in the status quo, we analyze the adsorption mechanism and influencing factors. Sawdust waste as one of.the important forest products, with a wide source of low-cost, renewable,etc. Its internal skeleton structure and large specific surface area material rich in hydroxyl, carbonyl, carboxyl reactive functional group, easy modification, adsorption good effect, has been widely used in water treatment research, future research directions are suggested, These directions include： fund out the plants for sawdust which show better performance or adsorption to specific pollutes, increase the application scale, develop safety disposal method and strengthen the researches on hydraulics, thermaldynamic and kinetics of adsorbent.
