Hollow fiber (HF) and flat sheet (FS) Sponge MBRs were operated at 10-20 LMH flux treating hospital wastewater. Simultaneous nitrification denitrification (SND) occurred considerably with TN removal rate of 0.011-0.020mg TN mgVSSd. Furthermore, there was a remarkable removal of antibiotics in both Sponge MBRs, namely Norfloxacin (93-99% (FS); 62-86% (HF)), Ofloxacin (73-93% (FS); 68-93% (HF)), Ciprofloxacin (76-93% (FS); 54-70% (HF)), Tetracycline (approximately 100% for both FS and HF) and Trimethoprim (60-97% (FS); 47-93% (HF). Whereas there was a quite high removal efficiency of Erythromycin in Sponge MBRs, with 67-78% (FS) and 22-48% (HF). Moreover, a slightly higher removal of antibiotics in FS than in HF achieved, with the removal rate being of 0.67-32.40 and 0.44-30.42µgmgVSSd, respectively. In addition, a significant reduction of membrane fouling of 2-50 times was achieved in HF-Sponge MBR for the flux range.
中空纤维（HF）和平板膜（FS）海绵 MBR 在 10-20LMH 通量下运行，处理医院废水。同时发生了相当程度的硝化反硝化（SND），TN 去除率为 0.011-0.020mgTNmgVSSd。此外，两种海绵 MBR 中抗生素的去除率都非常高，诺氟沙星（93-99%（FS）；62-86%（HF））、氧氟沙星（73-93%（FS）；68-93%（HF））、环丙沙星（76-93%（FS）；54-70%（HF））、四环素（FS 和 HF 均约为 100%）和甲氧苄啶（60-97%（FS）；47-93%（HF））。虽然海绵 MBR 中红霉素的去除效率相当高，达到 67-78%（FS）和 22-48%（HF）。此外，FS 中的抗生素去除率略高于 HF，分别为 0.67-32.40 和 0.44-30.42µgmgVSSd。此外，在通量范围内，HF-海绵 MBR 实现了 2-50 倍的膜污染显著减少。
