摘要：

Studying　the　effect　of　different　operation　conditions　(bovine　serum　albumin　(BSA)　concentration,　flux　and　stirring　speed)　on　the　membrane　fouling　behaviors　(the　variation　of　transmembrane　pressure　(TMP),　cake　resistance　(Rc),　pore　blocking　resistance　(Ri)　and　available　membrane　area　ratio　(A/A0))　is　of　paramount　importance　in　the　membrane　bioreactor　(MBR)　process.　The　constant　flux　filtration　experiment　was　conducted　to　investigate　the　fouling　behaviors　of　BSA　solution,　which　provides　a　guidance　for　controlling　the　membrane　fouling.　The　intermediate　blocking-cake　combined　model　was　established　and　it　was　described　mathematically　with　good　results.　The　results　showed　that　the　influence　sequence　of　operating　conditions　on　the　TMP　was　obtained　as　flux　＞　concentration　＞　stirring　speed.　Meanwhile,　Rc　decreased　with　the　increase　of　stirring　speed,　and　the　A/A0　decreased　with　the　increase　of　BSA　concentration　and　the　flux.　©　Content　from　this　work　may　be　used　under　the　terms　of　the　Creative　Commons　Attribution　3.0　licence.
