摘　　要：难生化降解的麦草浆造纸废水采用聚合硫酸铁(PFS)混凝工艺预处理,考察了工艺参数对去除CODCr和色度的影响。结果表明,各影响因素的优化结果为:PFS用量为2 g/L,混凝pH值为6.0,混凝转速为90 r/min,助凝剂种类为非离子型聚丙烯酰胺(NPAM),NPAM用量为0.1 g/L。在此条件下,CODCr去除率和脱色率分别为85%和93%。Given several process parameters including the amount of polymeric iron sulfate(PFS),the matching type and amount of coagulant aids,oscillating pH and the coagulation speed,and take PFS coagulation process to achieve the biochemical degradation of wheat straw pulp papermaking wastewater.The results show that the best value of the influencing factors is:2 g/L of the PFS,matching coagulant aids 0.1 g/L of wastewater,the reaction pH is 6.0,the coagulation speed is 90 r/min,the coagulant type is NPAM.Under this condition,the removal rate of the effluent COD Cr is 85%and decolorization rates is 93%.
