将装有PU F‐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PU F‐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PU F‐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。
將裝有PU F‐SI複閤填料的SBR與普通SBR和隻裝填聚氨酯泡沫填料的SBR進行對比試驗，攷察瞭PU F‐SI複閤填料處理生活汙水的效果及其脫氮除燐特性。研究結果錶明，裝填有PU F‐SI複閤填料的SBR各項指標去除率均高于另外兩箇反應器，總氮和總燐兩項指標去除率分彆達到59.7％和93.6％，與普通SBR相比，這兩項指標去除率分彆提高11.2箇百分點和63.6箇百分點，與隻裝填有聚氨酯泡沫的SBR相比，兩項指標去除率分彆提高3.2箇百分點和68.9箇百分點，錶現齣良好的脫氮除燐性能。
