Abstract

PURPOSE:To enhance the efficiency of removing SS of an upward current solid- liquid type separator in which filter media are packed by providing a stage for removing the SS by means of the upward current solid-liquid type separator with high efficiency to a stage before the stage for executing treatment by an aerobic filter bed. CONSTITUTION:Raw water which is org. waste water contg. the SS is admitted into the lower part in the solid-liquid separator 2 and is passed between the filter media 3 having >=70% voids and 0.9-1.0 sp. gr. in upward current. The SS are then efficiently removed in a short period of time. The waste water is then admitted into the aerobic filter bed 5 from the upper part and is passed between the granular filter media 6 in downward current. This waste water is aerated by the air supplied by an air diffusion pipe 5 into the lower part and is aerobically treated. The entire part of the treatment system is thereby constituted to smaller size. Since the solid-liquid separator in the fore stage has the high removal efficiency of the SS, the treatment function stabilize.
