The utility model discloses a floc re-flocculation suspension filtering device which comprises a tank body, and an inner cavity of the tank body is divided into a flocculation area, a settling area, a filtering area and a water storage area. The upper end of the flocculation area is communicated with the upper end of the settling area, the bottoms of the settling area and the filtering area are communicated to form a sludge discharging area, and the upper end of the filtering area is communicated with the water storage area. A water inlet and sludge return re-flocculation system is arranged in the flocculation area and is respectively communicated with an external sewage supply system and a sludge discharge area, so that to-be-treated sewage enters and sludge generated by precipitation, interception and filtration flows back to the flocculation area, and up-and-down circular flow is formed in the flocculation area to fully stir and react. According to the device disclosed by the utility model, the process com
