高分子有機膜材料：聚丙烯腈、聚砜類、含氟聚合物等?！　?/p>

有機膜，造價便宜，膜的制造工藝較為成熟，膜孔徑和形式也較為多樣，但運行過程易污染、強度低、使用壽命短?！　?/p>

無機膜：是由無機材料，如金屬、金屬氧化物、陶瓷、多孔玻璃、沸石、無機高分子材料等制成的半透MBR膜?！　?/p>

在MBR膜中使用的聚偏氟乙烯膜，長處是：它通量高、能耗相對較低，在高濃度產業廢水處理中具有很大競爭力；缺點是：目前使用數量較小、膜的加工制備有一定難題。

Polymer organic membrane materials: polyacrylonitrile, polysulfone, fluoropolymer, etc.

Organic membrane has low cost, mature manufacturing process, and various pore sizes and forms, but the operation process is easy to be polluted, the strength is low, and the service life is short.

Inorganic membrane: it is a semi permeable MBR membrane made of inorganic materials, such as metals, metal oxides, ceramics, porous glass, zeolite, inorganic polymer materials, etc.

Polyvinylidene fluoride membrane used in MBR membrane has the advantages of high flux, relatively low energy consumption and great competitiveness in high concentration industrial wastewater treatment; The disadvantages are: at present, the use quantity is small, and there are some problems in the processing and preparation of membrane.
