摘　　要：膜生物反应器处理污水过程中,依据胞外聚合物(EPS)、蛋白质、多糖、粘度等参数随时间的变化趋势以及对膜通量的影响,求出上述参数及蛋白质/多糖的比值与膜通量间的相关系数分别为0.28、0.57、0.38、0.14、0.70。结果表明:蛋白质/多糖的比值与膜通量的衰减速度两者相关系数最大。The changing trend of parameters with operation time,such as extracellular polymeric substances(EPS),protein,carbohydrate,viscosity,was studied.And the influence of parameters on membrane flux was also discussed.Moreover,the correlation coefficients of these parameters with membrane flux were obtained.That is,the coefficient of extracellular polymeric substances(EPS) was 0.28,protein was 0.57,carbohydrate was 0.38,viscosity was 0.14,the ratio of protein/carbohydrate in EPS was 0.70.The results showed that t...
