摘要： PURPOSE: To install a catalytic oxidation device before an outflow channel of a sedimentation basin, and to remove dissolved organic matter and floating polluted solid matter remaining in treated water by sedimentation in the sedimentation basin to improve its clarity. CONSTITUTION: Before an outflow channel of a sedimentation basin 1, an outflow stopping plate for stopping the inflow of treated water 4 is installed. A catalytic oxidizing material 6 is filled into a space between the stopping plate 4 and the wall of the sedimentation basin 1 to make it a catalytic oxidation device. The treated water in the sedimentation basin 1 is led to the lower part thereof by the outflow stopping plate 4, and is caused to flow in the catalytic oxidation device from the lower side thereof. The treated water gets rid of dissolved organic matter and floating polluted solid matter while coming into contact with the oxidizing material, and is discharged outside the system.

摘要： PURPOSE:To shorten the cleaning time of a filter medium by stirring and dispersing the filter medium with a raw water supplied, jetting the raw after into the filter medium after discharging the water and taking out he sewage after cleaning the filter medium from the bottom part of a closed tank at the time of cleaning the filter medium in an upflow type filter of the raw water. CONSTITUTION:When the raw water fed to the tank 1 from a main supply pipe 10 through a valve V2, a supply pipe 7a and a pit 7 is ascending in a filter medium layer 4, a contained dirt is captured and the filtrate is taken out from a discharge pipe 6a through a water collecting nozzle 3. At the time of clogging by the filtering operation, the filter medium is separated by rotating a stirring propeller 8 while continuously supplying the raw water and at the same time, the dirt is separated and only the separated water is discharged through the valve V5. Next, the rotation of stirring propeller 8 is stopped and the filter medium separated from the dirt is floated to form the filter medium layer. After that, the valve V5 is closed and the raw water through a valve V1 is reversely fed into the filter medium layer 4 from the nozzle 3 and the dirt is discharged from the valve 3.
