季戊四醇生产废水的生物降解

BIODEGRADATION OF WASTEWATER PRODUCED BY MANUFACTURING PFNTAERYTHRITOL

论述了季戊四醇的可生化性,及其在生物酸化-SBR串联反应器中的生物降解原理,季戊四醇在A/O过程中生化降解速度远高于连续曝气的好氧过程,废水中季戊四醇浓度小于1000mg/L时,不妨碍甲醛等有机物的降解,且季戊四醇在SBR出水中不会检出。

The biodegradability of pentaerythritol and the principle ofbiological degradation of pentaerythritol in a biological acidization-SBRseries reactor have been discussed.The rate of biodegradation of pentae-rythritol in A/0 process is much higher than aerobic process of continuousaeration.There is no obstruction on the degradation of organic compounds,such as formaldehyde, whne pentaerythritol's concentration is below 1000mg/L,and pentaerythritol is undetected in the treated water(outlet water)out of the SBR system.
