By investigating the relationship of extracellular polymeric substances(EPS) with bioflocculation and introducing kinetic model of organic pollutant degradation into EPS, the kinetic model of organic pollutant degradation for step-A hioflocculation was deducted. And through the experiments, the kinetic constants were calculated as follows: k1 =0. 005 3; kc1 =1 710.7 and vmax1=10 min^-1.展开更多
