(1)磷酸活化法
磷酸法制备活性炭的过程中,磷酸与木质纤维原料的作用机理可分为以下几个方面:润胀作用、加速活化作用、脱水作用、氧化作用和芳香缩合作用。 [2]
磷酸活化法的基本工艺包括木屑筛选、干燥、磷酸溶液配制、混合(或浸渍) 、炭化、活化、回收、漂洗(包括酸处理和水洗)、离心脱水、干燥与磨粉等工序,如生产颗粒活性炭还需增加捏合工艺。另外,附设专门的废气净化系统,回收烟气中的磷酸和炭粉,减少对环境的污染。磷酸活化法的生产工艺中,要注意在炭化段控制度,让磷酸充分渗透入木屑,再与活化段协同控制,可以明显提高活性炭吸附能力,产品质量稳定,同时适当降低活化温度对降低产品灰分有利。炭活化尾气采用多段液相回收可以增加磷酸和细炭粉的回收,采用高压静电方式也有利于尾气中焦油的去除。
(2)生物再生法
利用生物的新陈代谢,将吸附在活性炭上的污染物质氧化降解的方法称作生物再生法。活性炭的孔径一般只有几纳米,生物很难进入其孔隙内部,通常生物细胞酶可以流至细胞胞外,通过活性炭对酶的吸附,在炭表面形成酶促中心,分解污染物,达到再生的目的。生物法的投资和运行费用相对较低,但再生时间较长,水质和温度对再生效果的影响很大。同时,生物处理污染物的选择性很强,且一般不能将所有的有机物彻底分解成CO2和H2O,其中间产物仍残留在孔中,多次循环后再生效率会明显降低。
