Abstract

The features of organic pollutants degradation mainly characterized by bio-flocculation for step-A of adsorption-biodegredation (AB) process were studied. 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 bioflocculation was deducted. And through the experiments, the kinetic constants were calculated as follows: k 1=0.005 3; k c1=1 710.7 and v max1 = 10 min−1.
