Abstract：Anti-inflammatory agent (Naproxen) and antibiotics (Norfloxacin) were added into the sewage water separately to assess their effect on MBR performance. Membrane bioreactors show lower organic matters and nutrients removal when pharmaceuticals existed in treated water. Compared with traditional sewage water removal rate (COD was 89.84%, NH4+-N was 90.83%), the existence of Naproxen or Norfloxacin resulted in lower removal rate for COD (90.37% and 87.46%, respectively) and NH4+-N (70.12% and 73.68%,respectively). Undesirable settling property of active sludge was illustrated when adding Naproxen or Norfloxacin (even in low doses) into the test water. According to the TTC-ETS bioactivity test, Naproxen showed more poison effect than Norfloxacin, which was in accordance with the sludge sedimentation performance. Membrane fouling was illustrated by SEM and trans-membrane pressure analysis. The excess organic matter retained by membrane led to increasing membrane pollution. Critical pressure was reached about 30h ahead of normal time.

摘要：本文考察了水中萘普生或诺氟沙星对膜生物反应器除污性能的影响，包括去除COD、NH4+-N的效果对比分析、活性污泥沉降性能、微生物活性及微生物种群与数量等，同时从膜渗透压的变化及SEM分析，对膜污染状况进行了探讨。结果表明，诺氟沙星和萘普生对COD的去除效果影响不明显，COD的去除率从原来的89.84%分别达到87.46%和90.37%。诺氟沙星和萘普生对NH4+-N去除效果均有明显下降，去除率从原来的90.83%分别降到73.68%和70.12%。污泥沉降性能和微生物活性及PCR-DGGE分析表明，萘普生比诺夫沙星更易使污泥性能下降。诺氟沙星和萘普生使膜临界压力提前了30h，加速了膜污染。
