摘　　要：利用曝气生物滤池处理啤酒废水,通过监测分析挂膜阶段和正常运行过程中除去可溶性正磷酸盐的效果和反应池内的微生物相特征.结果表明,曝气生物滤池对磷酸盐的去除率在反冲洗后较短时间内就可达到最高,但很快就下降到负值,无法维持对磷酸盐的高去除率;另外发现若固着态微生物快速繁殖,可使曝气生物滤池迅速挂膜.The character of microbial morphology in a hanging-membrane phase and regular operation phase and the effect of removing dissolvable phosphate was analyzed in a device of BAF for the treatment of beer wastewater. It was shown that BAF can not continually remove considerable soluble phosphate because the removal rate of phosphate quickly achieves a maximum but then is soon reduced. It was also found that microbial morphology was obviously influenced due to hanging-membrane, back washing, and the height of the filter material.
