膜-生物反应器处理超市废水的试验研究
Treatment of Supermarket Wastewater in a Membrane Bioreactor
【摘要】 文章对一体式平板膜-生物反应器处理超市废水的特性进行了小试试验研究,结果表明,反应器对COD的平均去除率为91%,NH3-N平均去除率为86%。平板膜-生物反应器膜污染阻力构成为泥饼阻力占85%,孔隙堵塞阻力占13%,膜本身阻力只占2%,可忽略不计。
【Abstract】 A pilot scale study was done to treat supermarket wastewater in an integrated membrane bioreactor. Results showed that average removal efficiency of COD and NH3-N was 91% and 86% respectively. Analysis of membrane resistance distribution showed that resistance arising from cake formation was 85% of total resistance, resistance due to pore blocking was 13%, and clean membrane resistance was only 2% which could be omitted.
