PURPOSE: A dehydrator for treating wastewater is provided, which obtains efficient dehydration effect, doubles productivity, greatly improves filtering function of filter cloth and simply separates sludge cakes filtered on the filter cloth. CONSTITUTION: The dehydrator comprises a wastewater supply hole(103) formed on a protrusion body(102) formed at an upper side of filter plate(101) so as to receive wastewater through the wastewater supply hole(103); a supply passageway(104) for connecting the wastewater supply hole(103) and the depressed surface(107) to supply the wastewater supplied through the wastewater supply hole(103) to both sides of a depressed surface(107) of the filter plate(101); an assembly mold(111) assembled into an inserting hole of the filter cloth(132) connected to the wastewater supply hole(103) and the supply passageway(104) to supply the filtered wastewater to the depressed surface(107) after filtering the wastewater supplied to the supply passageway(104) using sludge cake filter cloth(132); a plurality of discharge passageways(109) formed at a lower side of the depressed surface(107) to discharge water filtered by the filter cloth(132) of the assembly mold(111) to the outside; and a plurality of discharge holes(108) connected to the discharge passageways(109) to discharge water of the discharge passageways(109) to a water tank, wherein the dehydrator further comprises washing water supply holes(105) formed at upper both sides of the filter plate(101) to supply clean water, and injection holes(106) for connecting the washing water supply holes(105) and the depressed surface(107) to supply water of the washing water supply holes(105) to the depressed surface(107).
