摘要： PURPOSE:To simply and inexpensively purify sewage by arranging a water tank having an inflow port and an outflow port formed to one and other ends thereof respectively in a channel such as rivers along a flow direction and arranging a large number of sheet like contact materials using bacteria in the water tank. CONSTITUTION:A water tank 5 having an inflow port 7 and an outflow port 8 respectively opened to one and other ends thereof is arranged in a channel such as rivers along a flow direction and the water tank 5 is packed with a plurality of contact material units wherein a large number of sheet like contact materials 1 using bacteria are parallelly arranged so that the contact materials 1 are arranged along the flow direction of the channel. Air diffusion pipes 3 and sludge withdrawing pipes 10 are arranged to the bottom part of the tank under the contact material units in the direction traversing the channel. Sewage flowing in the water tank 5 comes into contact with bacteria deposited on the contact materials 1 while flows through the gaps between the contact materials and org. matter in sewage is subjected to oxidative decomposition to purify sewage. By this constitution, energy is conserved by utilizing natural flow-down of rivers and bacteria are utilized to reduce maintenance cost.

摘要： PURPOSE: To completely clean and reproduce a filter material with a small quantity of cleaning water by installing a flowing down path for the filter material between an upper part aperture of a treatment tank and a filtered liquid chamber in the lower part of a filter layer and installing a filter transporting apparatus and a filter cleaning apparatus in the flowing down path. CONSTITUTION: A floating filter material 2 which captures foreign matter in raw water and is therefore choked goes up by supplying raw water still more and finally flows over to a flowing-down path 6 from an upper part aperture of a treatment tank 1. Meanwhile, at the same time, the floating filter material 2 which flows over to the flowing-down path 6 is drawn by a screw conveyer 8 by driving the screw conveyer 8 and a pump 12, flows down in the flowing-down path 6, and is cleaned with cleaning water from a cleaning nozzle 7 in the middle of the way. In this way, the floating filter material 2 which is cleaned primarily is transported to a treatment tank 1 by the screw conveyer 8 and then whose water content is discharged to a clearing cylinder 9 from a rising up part of the cylinder. The filter material 2 is cleaned secondarily with filtered liquid which flows in the cleaning cylinder 9 by opening a valve 10.
