The invention discloses a precipitate micro-filter. The precipitate micro-filter comprises a box body; the box body is divided into a coagulation area, a precipitation area, a filtering area and a clean water area sequentially from left to right; the coagulation area is embedded in the middle part of the left end of the precipitation area and clings to the inner wall of the left side of the box body; a water inlet pipe and a water outlet pipe are arranged on the left upper side and the right lower side of the box body correspondingly; mud discharge pipes are arranged on the front side and the back side of the precipitation area; a gathering plate is arranged at the bottom of the precipitation area; an overflow partition plate is arranged in the clean water area; precipitation inclined pipes which are arranged in parallel are arranged in the middle of the precipitation area; a supporting frame is arranged at the bottoms of the precipitation inclined pipes; a water distribution pipe communicating with the coagulation area is arranged on the lower side of the supporting frame; an overflow groove is formed in the left right side of each precipitation inclined pipe; an overflow bend is arranged on the right side of the overflow groove; a rotating roller is arranged in the middle of the filtering area; more than two groups of filtering rotating disks are arranged on the rotating rollers; and filtering cloth covers the filtering rotating disks. The precipitate micro-filter has the beneficial effects of low use cost and invested cost, no secondary pollution and waste, good precipitation effect and high efficiency.
