PURPOSE:To facilitate maintenance control by reducing the load to a filter tank, by mounting a dehydration apparatus, which is equipped with a foldable strip shaped filter for filtering sludge water fallen from a perforated plate and collects sludge, an extrusion apparatus and a filter apparatus. CONSTITUTION:The sewage in a tank 8 is transferred to a stirring tank 10 through a flow meter 9 by a pump 8A. A treating agent is added to the stirring tank 10 and a precipitate or a flocculated substance is generated through reaction to be separated from water. The sludge water after reaction is precipitated to a sump part 10A and sent to a dehydration apparatus 22 by using a valve 23 and uniformly fallen on the strip shaped filter 27 on a conveyor 26 through the apertures of a perforated plate 25. Water as a floc separated liquid passing through the filter 27 is accumulated in a tank 29 and returned to the tank 8. The filter 27 is received in a treating box 30 in a stacked form while folded. |
