摘　　要：将装有PUF-SI复合填料的SBR与普通SBR和只装填聚氨酯泡沫填料的SBR进行对比试验,考察了PUF-SI复合填料处理生活污水的效果及其脱氮除磷特性。研究结果表明,装填有PUF-SI复合填料的SBR各项指标去除率均高于另外两个反应器,总氮和总磷两项指标去除率分别达到59.7%和93.6%,与普通SBR相比,这两项指标去除率分别提高11.2个百分点和63.6个百分点,与只装填有聚氨酯泡沫的SBR相比,两项指标去除率分别提高3.2个百分点和68.9个百分点,表现出良好的脱氮除磷性能。The capability of the polyurethane foam and sponge iron （PUF-SI） composite fillers in domestic wastewater treatment was investigated by comparing three SBR reactors which were filled with PUF-SI composite fillers SBR reactor, conventional activated sludge SBR reactor and filled with polyurethane foam filler SBR reactor respectively. The results showed that PUF-SI com- posite fillers SBR reactor showed best performance on removing COD, NH3--N, TN and TP. Es- pecially, its average removal rate of TN and TP reached 59.7% and 93.6%. Compared with the conventional SBR reactor, the nitrogen and phosphorus removal rate increased by 11. 20% and 63.6 % respectively~ compared with the only two indicators increased by 3. 2% and 68. 9 performance was satisfying. filled with polyurethane foam filler SBR reactor, these respectively. Its nitrogen and phosphorus removal
