摘　　要：为了探索在SBR法处理制浆中段废水过程中投加固定化漆酶结合处理的效果,进行平行对比实验。结果表明,SBR法结合固定化漆酶处理废水,CODCr去除率从单纯的SBR法处理时的84%上升到90%左右,出水CODCr在120mg·L-1以下;BOD5去除率也从90%上升到95%左右;出水色度从原来的100倍下降到50倍左右。In this experiment, the effect of SBR-immobilized laccase on middle stage effluent treatment was mainly studied. Through the parallel and contrastive experiment, the results showed that, the significant effect was obtained by SBR-immobilized laccase actor. CODCr removal rate rose to 90% comparing with 84% only treated by SBR, and the effluent CODcr was 120mg·L^-1 below. BOD5 removal efficiency rose from 90% to 95%. The chroma of effluent declined from 100 to 50 times.
