Abstract

PURPOSE: To raise filtration capacity by always renewing a filter medium packed layer in a rectangular moving bed type filter by virtue of slant downward flow of the water to be treated and rotation of filter medium dischargers.
CONSTITUTION: Waste water containing suspedned matters is fed from water feed pipe 1 to water receiving sections 6 of a filter having a plurality of rectangular filter medium packed layers 5. Metallic screen parts 9 higher on the sides of sections 6 and lower on the sides of treated water receiving sections 7 are provided on the lower parts of supporting plates for forming filter medium packed layers 5, the water flows slantly downward through layers 5 from sections 6, and suspended matters contained in the water are filtered. Clear treated water is discharged through sections 7 and discharge pipe 3. The filter medium is fed to each layer 5, allowed to flow down by virtue of slant downward flow of the water and rotation of filter medium dischargers 10 without stagnating in layers 5, thus permitting filtration performance to be deteriorated, and a filter of large capacity in a small size to be obtained.
