Under different sludge concentrations and fluxes, the changes of transmembrane pressure, combined with changes of the appearances of the fouled membrane surface were investigated, to dynamically analyze membrane fouling process of a submerged membrane bioreactor
結合膜過濾壓差的上升和污染膜表面微觀形態的變化，對不同污泥濃度和膜通量條件下，一體式膜生物反應器中膜污染過程進行了動態分析。 -
Soluble organic foulants contributed little but sludge particles deposited on the membrane surface resulted in a rapid increase of the transmembrane pressure
溶解性有機物在膜面的附著，對膜過濾壓差即膜過濾阻力的變化影響不大，而活性污泥在膜表面的大量沉積將導致膜過濾壓差迅速上升。 -
This is to say, pu composite hollow fiber membranes pore size can become large with transmembrane pressure increasing, and can recover completely with transmembrane pressure reverting to original pressure at a specification condition. from the hagen - poiseuille equal ion, pu composite hollow fiber membrane pore radius magnification was calculated. in our experiment, the variation of membrane pore radius attained to much six times larger than the primitive membrane pore radius
根據一般非變形膜的純水通量一壓力差的直線關系，首次提出了孔徑變化分離膜的純水通量一壓力差的曲線關系，並根據hagenf公式，理論上計算出了幾種pu復合中空纖維膜最大變形時的膜孔徑為原始膜孔徑的倍數，最小膜孔徑變化也達到原始孔徑的一倍多，最大膜孔徑變化達到原始孔徑的六倍多。 -
5 have a better recovery. the flux - transmembrane pressure curves of several kinds of pu composite hollow fiber membranes differed completely from non - deformation membranes, deviated from the linear relation obviously. this strongly indicated that, due to pu characteristics, such as good elasticity and strong recovery, pu - sio2 composite hollow fiber membranes have a comparatively good pressure - responsivity
通過調整紡絲液濃度、 sio _ 2含量、中空芯液流量、紡絲溫度、凝固浴溫度等參數，紡制出5種較為理想的壓力響應性pu復合中空纖維膜，其中，含有20和25 sio _ 2的pu復合中空纖維膜孔徑增加和孔徑回復最為理想。
