The invention provides an acid mine wastewater treatment system based on microbiological treatment. The acid mine wastewater treatment system comprises a regulating tank, an aeration tank, a neutralizing tank and a dissolving tank which are arranged in sequence, wherein a bacterial liquid adding device, an aeration stirring device and two groups of collecting devices are arranged in the aeration tank, and the aeration stirring device is arranged between the two groups of collecting devices, so that sediments can be forced to be collected in the collecting devices while the oxygen content of the wastewater is increased. The collecting device comprises a guide rod group fixed at the bottom of the aeration tank, a movable plate frame connected to the guide rod group in a sliding manner and a hoisting mechanism for forcing the movable plate frame to lift, and a gauze bag for collecting sediments is detachably mounted at the bottom of the movable plate frame; in the initial state, the movable plate frame and the g
