The present invention relates to a screw-type low-speed solid-liquid separation apparatus. The screw-type low-speed solid-liquid separation apparatus comprises: a base frame; a case in which a discharge space portion, a treated water discharge portion, and a solid discharge portion are formed; a cylindrical screen part which has a plurality of dewatering holes, is rotatably provided in the discharge space portion of the case, and separates treated water and solids from raw water and discharges the treated water and the solids; a feeding means which feeds raw water including solids to the cylindrical screen part; a transfer scraping means which is provided in the feeding means in a screw form, comes into contact with an inner surface of the cylindrical screen part, and removes solids from the dewatering holes and transfers the solids to the solid discharge part; and a driving means which rotates the cylindrical screen part and the feeding means at different rotation speeds. According to the present invention, treated water and solids are separated while raw water is being rotated at low speed, and solids caught on the cylindrical screen part are removed by the screw-type transfer scraping means and can be easily transferred to the solid discharge part, thereby improving dewatering rate of solids. |
