厌氧酸化菌产酸过程研究

Research on the Acidolysis Process of Anaerobic Acidification Bacterium

摘要:

以葡萄糖模拟废水为研究对象,在温度37±0．5℃下,通过对不同影响因素下酸化过程的研究,确定水解酸化最佳条件为pH=6．5。重点对此条件下水解酸化过程中产酸速率的动力学进行了推导,通过计算,得出此条件下的动力学常数为V_max=8．45d^-1,K_s=1,089mg/L。说明了酸化过程较好氧过程和完全厌氧过程快的理论依据。

Abstract:

Acidolysis kinetics on the process of the hydrolysis acidification by using glucose as the only energy sources was researched.It was concluded that the acidolysis kinetics constants are V_max=8.45d^-1 and K_s=1089mg/L,under the circumstances of a temperature 37℃±0.5℃and the influent pH value 6.5.The results show that the rate of anaerobic acidification process is greater than that of completed an- aerobic or anoxic process.
