FIELD: process engineering.
SUBSTANCE: invention relates to equipment intended for storm flows cleaning of oil products and suspended substances and can be used for cleaning storm flows and industrial effluents. Proposed device comprises settling zone, coalescence zone, two-level cylindrical mechanical filter with major working surface of oleophilic sorption material, floating bed filter and sorption filter with activated charcoal. Settling zone is equipped with oil products collector comprising oil product withdrawal pipeline, flow distributor and inclined baffle for concentration of oil product film in oil product withdrawal container. Coalescence zone is provided with oil product film collection tray wherefrom said film is forced into settling zone by pump. Two mechanical quartz-sand-filled filters are located downstream of coalescence zone. Purified water is discharged from sorption filter with activated charcoal from its top section.
EFFECT: higher quality of cleaning.
