醋酸废水的压力生物膜法处理

DISPOSED OF ACETIC WASTE-WATER BY PRESSURE BIO-FILM METHOD

将物理中总压与分压的概念应用于醋酸废水的生物膜法处理中。实验结果表明 ,适当增加空气的压力 ,不会伤害微生物 ,并且由于氧分压的增加更提高了氧的传递推动力 ,有利于生物氧化处理 :对比在 0 .2 MPa、0 .3MPa较常压下 COD去除率增加 30 % - 40 %。

Here,the acetic waster water was disposed by pressure bio film method through the principle of Dolton partial pressure law,the experiment results show that increasing air pressure would not harm microoraganism,otherwise,it would be benefit to the bio film oxidation processes.The removal efficiency of COD was increasing 30%-50% at 0.2 MPa and 0.3 MPa atomsphere pressure compared with normal pressure.
