吸附生物降解法(AB工艺)A段反应机理分析

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

讨论了AB工艺由于其独特的工艺流程 ,改变了以往传统的活性污泥法建立动力学方程的边界条件 ,AB工艺A段在动力学方面与普通活性污泥法有所不同 ,本研究提出AB工艺A段主要是通过微生物的酶解作用 ,改变SS胶体颗粒的表面性质 ,促进其相互间吸附 ,絮凝的过程 。

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 process. This paper points out that section A of AB process can change the surface property of SS colloid particulates, promote the process 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.
