The utility model belongs to the technical field of environment friendliness and mainly relates to an upward flow biofilm reaction device. The treated water flows into a water inlet trough (102) by a water inlet (101) and then is uniformly distributed into a plurality of water inlet distribution tanks (104) through water inlet tank triangular weirs (103), is uniformly distributed into the bottom of a reaction tank (100) through a plurality of water inlet distribution pipes (105), then upwards flows and is uniformly distributed again through a grille filler partition plate (400) or a long-handle filter head; the treated water flows through the filler and is uniformly distributed through a plurality of water-producing triangular weirs (202) arranged at the upper part of the reaction tank for three times and finally flows out through a by-product water trough (203) and a main-product water trough (204). Since the water flow is homogenized for many times, the efficiency of the reaction tank is significantly improved.
