A screw type of solid-liquid separation equipment of which volume is reduced, which can perform cleaning of very small gaps very well, and which prevents the cleaning means from being broken down and enables the cleaning means to be installed and dismantled promptly and simply by simplifying the structure of cleaning means, is provided. A screw type of solid-liquid separation equipment comprises: a casing(10) having a sludge inlet(11) formed at one side thereof, a solid outlet(12) formed at the other side thereof, and a catchment part(14) formed on a lower part thereof; separation means(20) comprising supporting plates(27a,27b) installed at at least both sides of the casing, a plurality of fixing rings(21) fixed between the supporting plates to form very small gaps(g) therebetween, and a screw-inserting space part(S) formed in the fixing rings; a screw(30) which is inserted into the screw-inserting space part, and on which a spiral blade(32) is formed; and cleaning means(40) comprising supporting members(41) fixed onto an outer peripheral surface of the spiral blade in an axial direction of the screw, and a plurality of cleaning blades(44) which are supported and connected to the supporting members and are inserted each into each of the very small gaps such that the cleaning blades are rotated only by rotary power of the screw.
