摘要
活性焦是一类中孔发达、表面官能团丰富的类活性炭材料。其优异的吸附性能已在烟气净化方面得到体现。在水处理领域,活性焦适用于处理含有结构复杂的大分子有机物废水。因此,对活性焦吸附处理含油废水、煤化工废水、炸药废水及特异污染物等方面的研究进展进行了综述。指出机理是氢键和离子交换作用,发生化学吸附;通过改性可提高活性焦的吸附容量,与其他工艺组合可提高处理效率;对复杂有机物的吸附机理的深入研究及吸附后再生方法是今后的研究重点。
Activated coke(ACoke)is a kind of analogous activated carbon(AC)materials with more mesoporous and multiple functional groups.Its excellent adsorption performance has been reflected in the flue gas purification.The ACoke used in the field of water treatment,such as oily wastewater,coal chemical wastewater,explosive wastewater and specific contaminants,containing macromolecular organic compounds with complex structures,are reviewed.The mechanism is hydrogen bonding,ion exchange and chemisorption.Adsorption capacity of ACoke can be improved by modifying,and combined with other processes to enhance processing efficiency.Research on the adsorption mechanism of complicated compounds by ACoke and new recycle methods will be important research field.
