摘要
在制浆造纸工业中含木素衍生物和其它化合物的废水主要来源于备木车间、机械浆车间和漂白车间。这些化合物中有许多是有毒的,这给废水生物处理带来了不利的影响,并且这些物质是废水色泽的主要来源。现有的技术很难除去,但在一种酚型氧化酶存在下曝气,可使酚型化合物聚合进而沉淀或在硫酸铝的作用下絮凝出去。
The waste water including lignin-ramification was mainly from pulping stage and bleaching stage. Most of these compounds were poisonous, brining about the colour of waste water and a damage to biotreatment of waste water.It is difficult to remove those compounds through general methods, while it was showed that those phenol-compounds were able to be polymerized through insolation with phenol oxidization enzymes, forming deposit or floc with alum.
