在水力停留时间为0.5h的条件下，对浸没式膜生物反应器（sMBR）处理微污染地表水进行了为期110 d的小型中试试验。sMBR通过生物硝化实现了对氨氮的完全去除（去除率为89.4%）。然而，sMBR去除有机物的能力被证明是低的。TOC、CODMn、DOC、UV 254以及相应的THMFP和HAAFP的平均去除率分别为28.6%、33.5%、21.5%、15.1%、34.1%和24.7%，BDOC和AOC的平均去除率分别为51.7%和54.9%。在sMBR中，在UF膜表面上观察到污泥层。污泥层对混合液中溶解性有机物（DOM），特别是5000- 500 Da范围内的有机物分子具有额外的过滤作用。对DOM的分离结果表明，污泥层和超滤膜对疏水性中性物质、疏水性酸和弱疏水性酸的截留率分别为45.0%、42.7%和48.1%，而对疏水性碱和亲水性有机物的截留率分别为11.3%和14.6%。
The mini-pilot experiments of submerged membrane bioreactor (sMBR) for the drinking water treatment from a slightly polluted surface water supply was conducted for more than 110 days, with a hydraulic retention time of 0.5h. Perfect ammonia removal (by 89.4%) were achieved by the sMBR through the biological nitrification. However, the capacity of the sMBR for organic matter removal was demonstrated to be low. The average removal efficiencies for TOC, CODMn, DOC, UV254, and corresponding THMFP and HAAFP were 28.6%, 33.5%, 21.5%, 15.1%, 34.1% and 24.7%, respectively, though much higher removal of 51.7% and 54.9% were obtained for BDOC and AOC, respectively. A sludge layer was observed on the UF membrane surface in the sMBR. The sludge layer could provide additional filtration for dissolved organic matter (DOM) in the mixed liquor, especially for organic molecules in the range of 5000–500Da. Fractionation of DOM indicated that the sludge layer together with the UF membrane had the ability to reject hydrophobic neutrals, hydrophobic acids, and weakly hydrophobic acids by 45.0%, 42.7% and 48.1%, respectively; whereas hydrophobic bases and hydrophilic organic matter were separated mainly by the UF membrane, with the efficiencies of 11.3% and 14.6%, respectively.
