%X There is a lot of polymer-contained sewage produced from polymer flooding process in Daqing oilfield. As polymer is the main factor that determines the water characteristics, the mechanism of UF flux influenced by polymer-contained sewage is different from that done by common oil-contained sewage. The mechanism of flux decline was showed through theoretically analyzing in terms of feed-water rheology, operation pressure, cross-flow velocity, polymer concentration and various resistances. The results indicated that the mechanism of flux decline was resulted by concentration polarization and gel layer formation of polymer, and the other reason was that crude oil and inorganic matter plugged membrane pores.
