摘要
以悬浮填料为生物载体的膜生物反应器连续运行两个月表明,在投加悬浮填料的反应器内不需投入活性污泥.悬浮性生物量降低到1 g/L以下,在很大程度上减轻了对膜组件的污染.与此同时,由于填料的投加,延迟了曝气气泡上升的时间,极大地提高了氧的传质率和利用率,大大节省了能源消耗,降低了处理成本.出水水质同常规MBR相比几乎没有差别,可以满足中水回用的水质标准.
Suspended carrier is added to the membrane bioreactor as the media of biomembrane, and it's two months continual running shows that sludge is unnecessary to be added in the reactor and the suspended solid (SS) is decreased to below 1 g/L, which alleviates the fouling of the MBR system in large extent. Furthermore, for adding the carrier, the time of air uprising in the water is prolonged, so the transmission and availability of oxygen will be improved eorrespondently, which economizes the dissipation of energy, and widely saves the processing cost. The quality of the outlet water by this process is nearly the same as that by the traditional MBR system and reaches the standard of reused water.
