脱氮活性污泥降解乙酸根试验

Acetate degradation by denitrifying activated sludge

本文报道脱氮活性污泥降解乙酸根的过程.分析了过程中pH值、PO2、TOC、TS等的变化情况.在本实验条件下,乙酸根的降解可在10～24h内完成.不同的pH值介质对降解速率有显著的影响.降解过程中pH值会升高1.4～1.7个pH值单位.将pH值始终控制在7.4时,降解速度显著减慢.

Acetate was degraded by denitrffying activated sludge. Variations of pH, PO2, TOC, TS in degradation process were discussed. Acetate completed degradation by denitrifying sludge expended 10 - 24h. The process was influenced stank by pH value and in process pH value raised 1.4 - 1.7pH unit. The degradation rate was reduced if pH value at 7.4 was controlled.
