摘　　要：以造纸厂剩余污泥为原料制得微生物絮凝剂LBF,通过实验确定了使用LBF和另一种生物絮凝剂CBF处理造纸废水和生化出水的最佳使用条件。在最佳条件下,LBF处理造纸废水后COD去除率为39%,SS去除率为87%,色度去除率为71%;以CBF处理,COD、SS、色度去除率分别为47%、75%、44%。与PAC相比,微生物絮凝剂LBF、CBF处理造纸废水的效果更好。Microbial flocculant LBF has been prepared by using the residual sludge in paper-making plants as raw material. Through experiments,the best service conditions of using LBF and another biological flocculant CBF for treating paper-making wastewater and biologically treated effluent are determined. Under these conditions,the removing rate of COD, SS, chroma after the wastewater is treated with LBF are 39%, 87%, 71%, respectively. By using the other bio-flocculant （CBF）,the removing rate of COD,SS, chroma are g7%, 75% ,44% ,respectively. Compared with traditional flocculant （PAC）, microbial flocculants CBF and LBF have better treatment effects on paper-making wastewater.
