摘要
本课题通过对比试验对生物除磷的电场强化作用及其动力学进行了初步研究,结果表明,在试验条件下(电流密度:i=0．04～0．08mA／cm2),无论哪个反应时段(厌氧段、好氧段)施加电场,对提高、稳定生物除磷效率都有积极的作用;且厌氧放磷反应及好氧吸磷反应都近似地符合一级动力学规律,电场可增大厌氧放磷及好氧吸磷速率常数,从而提高、稳定生物除磷效率。
The aggrandizement of electric field of biological dephosphorization and kinetics were studied in this paper. The results demonstrated that in both reaction periods, the electric field contributed to the efficiency and stability of dephosphorization, and the rate of phosphorus uptake and release were consistent with the first-order kinetics, furthermore, electric field could increase velocity constants and accordingly enhance efficiency of biological dephosphorization.
