摘要
研究了膜生物反应器（MBR）处理酒精生产废水的特性和效果。探讨了生物降解和膜滤作用对CODCr、氨氮（NH＋4-N）、总氮（TN）、总磷（TP）的降低效果以及膜组件运行压力等。研究结果表明,膜生物反应器（MBR）中生物在2~4 h内对CODCr、氨氮（NH＋4-N）、总氮（TN）、总磷（TP）的降解效果明显,而膜滤是强化生物降解效果的补充,对CODCr,NH＋4-N,TN和TP的去除均有着不同程度的效果,说明膜生物反应器能净化酒精生产废水。
The characteristics and effects of alcohol wastewater treatment by membrane bioreactor（ MBR） is studied.The removal efficiency of biodegradation and membrane filter on chemical oxygen demanded（ CODCr）,ammonium（ NH＋4- N）,total nitrogen（ TN） and total phosphorus（ TP） is investigated,as well as operational pressure of membrane. The results indicate that the biodegradation efficiency of CODCr,NH＋4- N,TN and TP is obvious within 2-4 hs. The membrane filter is good to biodegradation and effective to the removal of CODCr,NH＋4- N,TN and TP.The phenomenon illustrates that the membrane bioreactor has better ability for purifying alcohol wastewater.
