摘要： In a submerged membrane bioreactor (MBR or SMU), diffusers are used to eject air bubbles, primarily to facilitate the movement of mixed liquor past the membrane surfaces, cleaning and scouring the surfaces of the membranes with the mechanical energy of the combined air/liquid/solids movement. Oxygen transfer from the bubbles into the mixed liquor is often a secondary goal, for supplying oxygen to biological processes. The invention involves the use of a specific bubble diffuser, oriented at a selected upward angle, to enable a single style diffuser to accomplish simultaneous generation of mid-size and fine bubble aeration, with adjustment of the tilt angle varying the percentages of mid-size and fine bubble aeration. The angle selection, along with the number of diffusers and air volume selected, allows achievement of target liquid movement through the MBR.

摘要翻译： 在浸没式膜生物反应器（MBR或SMU）中，扩散器用于喷射气泡，主要是为了便于混合液体通过膜表面的移动，用组合的空气/液体的机械能清洗和冲洗膜表面 /固体运动。 氧气从气泡转移到混合液中通常是将氧气供给生物过程的次要目的。 本发明涉及使用特定的气泡扩散器，其以选定的向上的角度定向，以使得单一型式的扩散器能够同时产生中等尺寸和细小的气泡曝气，其中倾斜角度的调整改变了中等尺寸 和细气泡曝气。 角度选择以及所选择的扩散器和空气量的数量允许通过MBR实现目标液体运动。
