摘　　要：针对活性碳纤维(ACF)只能吸附多种有机污染物,并不分解污染物,而纳米光催化可以光降解有机污染物,但只在污染物浓度较高时有优异的光降解性能,而当污染物浓度较低时,光催化降解速率较慢,影响净化效果等问题,将纳米光催化与ACF吸附技术相组合,研究了二者组合后的吸附光催化机理及对ACF滤料的阻力等.ACF can adsorb many organic contaminations, but now ACF is only using for displace infectants and cannot decompound them. Nanometer Photocatalysis can decompose the organic contaminations,but the concentration of infectants is high. Because low concentration can reduce the velocity of decompose and affect the purification effect. Thereby, combined nanometer Photocatalysis and ACF adsorbent technology,its adsorption and Photocatalysis principle are investigated.
