                          活性炭处理印染废水
                          印染废水主要由退浆废水、漂白废水、染色废水和印花废水等组成,印染废水一般具有污染物浓度高、种类多、含有毒有害成分及色度高等特点。因此要采取有效的方法进行处理,吸附作用是活性炭的首要指标。
                          活性炭微孔的孔隙容积一般只有0.25-0.9mL/g,孔隙数量约为1020个/g,全部微孔表面积约为500-1500m2/g;钚蕴考负95%以上的表面积都在微孔中,因此除了有些大分子进不了外,微孔是决定活性炭吸附性能高低的重要因素。中孔的孔隙容积一般约为0.02-1.0mL/g,表面积最高可达几百平方米。其作用能吸附蒸汽,并能为吸附物提供进入微孔的通道,又能直接吸附较大的分子。
                          大孔的孔隙容积一般约为0.2-0.5 mL/g,表面积只约0.5-2 m2/g,其作用一是使吸附质分子快速深入活性炭内部较小的孔隙中去;二是作为催化载体时,催化剂常少量沉淀在微孔内,大都沉淀在大孔和中孔之中。很多吸附是可逆的物理吸附,即被吸附物为流体,在一定温度和压力下被果壳活性炭吸附,在高温低压下被吸附物又解吸出来,活性炭内表面恢复原状。
