The present invention relates to a membrane filtration system and a membrane bioreactor comprising same. The present invention comprises: a treatment tank; a membrane support frame disposed in the treatment tank and having a separator membrane provided thereto; a separator membrane module provided to the membrane support frame; a vane member disposed on a lower end of the membrane support frame so as to enable sludge accumulated on a lower portion of the treatment tank to float; and a reciprocation means connected to the membrane support frame so as to enable the membrane support frame to reciprocate, wherein the separator membrane module may comprise an upper frame and a lower frame, and a hollow fiber membrane interposed between the upper frame and the lower frame. According to the present invention, mobility is stabilized when flowability is given to the separator membrane by enabling the separator membrane to reciprocate in order to remove foreign substances attached thereto, and thus the foreign substances may be effectively removed.
