Abstract

This utility model discloses an integrated fiber disc filter for wastewater treatment, comprising a tank body, a treatment tank, an effluent tank, and an influent tank located inside the tank body, a fiber disc rotatably installed inside the treatment tank, a reduction motor installed on the top of the tank body, with the output end of the reduction motor connected to the central shaft of the fiber disc via a chain; and a detachable coarse filter assembly, comprising a rectangular top plate and two rectangular insert frames fixed to the bottom of the rectangular top plate. This utility model improves and optimizes the existing integrated fiber disc filter for wastewater treatment by adding a detachable coarse filter assembly. This allows wastewater to undergo preliminary coarse filtration by two metal filter screens after entering the influent tank through the influent pipe, filtering out larger impurities and foreign objects in the wastewater before flowing into the treatment tank for fine filtration by the fiber disc. This improves the filtration efficiency of wastewater and reduces the filtration burden on the fiber disc.
