ANALYSIS OF REACTION MECHANISM OF SECTION A OF ADSORPTION BIODEGRADATION PROCESS (AB PROCESS)

The fact is discussed that the adsorption biodegradation process (AB process)due to its peculiar process flow has changed the boundary conditions which establish a kinetic equation by the traditional activated sludge process.The kinetics of section A of AB process are different from those of the normal activated sludge prdcess.This paper points out that section A of AB process can change the surface property of SS colloid particulates, promote the proceass of mutual adsorption and flocculation mainly by microbial enzymolysis.The order of reaction and the kinetic model of section A of AB process are also studied.
