摘要
采用固定化漆酶深度处理制浆造纸废水，取得了良好的处理效果。最佳工艺条件：控制固定化漆酶的投加量为0．2g/L，废水pH为6．5，CuSO4投加量为10mg／L，HBT投加量为4mg/L，在25℃曝气反应8h后色度去除率可达85％左右，COD去除率达12．51％。若把HBT改为磷钼酸，控制磷钼酸投加量为500mg／L，反应8h后色度去除率达50％左右。
The immobilized laccase was used for papermaking wastewater deep treatment. The optimal conditions were obtained： control of immobilized laccase dosage was 0.2 g/L, wastewater pH 6.5, CuSO4 dosage was 10 mg/L, HBT for 4 mg/L, at 25 ℃ aeration reaction 8 h, color removal up to 85%, COD remove rate of 12.51%. The HBT replaced by phosphomolybdic acid, control of phosphomolybdic acid dosage was 500 mg/L, chroma removal rate was about 50% aider reacted for 8 h.
