中文摘要：
在漆酶催化作用下，添加的对-羟基肉桂酸能与化机浆APMP废水中的可溶性木素及其衍生物发生聚合反应，从而生成疏水性的大分子聚合物而沉淀除去。实验表明：在漆酶的作用下添加对-羟基肉桂酸可以有效地除去废水中的可溶性木素及其衍生物，在对-羟基肉桂酸用量为0．066g／L，漆酶用量为14．82IU／L，处理温度为25℃，处理时间为1h的条件下废水的处理效果最好，木素的脱除率可达73．g％，CODCr的去除率可达69．1％，色度脱除率为86．7％。
英文摘要：
Under the laccase catalysis, the water soluble lignin in APMP effluent and its derivatives were polymerized with p-hydroxycinnamic acid to form high molecule hydrophobic lignin polymer which will be removed by sedimentation. The results of the experiment indicate that addition of p-hydroxycinnamic acid could effectiveiy remove soIuble lignin and its derivatives in the effluent under the reaction of laccase. The optional effluent treatment condition： p-hydroxycinnamic dosage 0.066 g/L, laccase dosage 14.82 IU/L, temperature 25℃, reaction time lh. The removal rate of lignin reached 73.9%, the removal rate of CODCr was 69.1% and the chroma removal rate was 86.7% respectively.
