Wastewater treatment facilities having biofilm contact and solid-liquid separation functions are disclosed, wherein a biofilter unit having biofilm contact, inclination plate precipitation and de-filming functions comprises an inclination plate settler formed with a plurality of inclination plates (2), each plate spaced in parallel relative to water surface at a predetermined downward angle and a predetermined distance apart, and spacings formed by the plates (2) are filled by biofilm media (3,3a) formed with specific surface-increased and bio-affinity materials so that micro-organisms can attach and grow in the shapes of biofilms therein, and de-filming means for separating biofilms attached to and grown on the biofilm media (3, 3a) and solids deposited on the surfaces of the inclination plates (2) by applying shearing force to biofilm media (3, 3a) and inclination plates (2).
A biofilter unit comprising:
A water treatment facility using a biofilter unit, wherein at least one or more biofilter units (1a, 1b) of any one claim of 1 to 7 are disposed on at least one or more reactors (22, 24) in a wastewater treatment facility comprised of one or more reactors (21,22, 23, 24) and a settling chamber (20a), and a clarified effluent passage of the biofilter units (1a, 1b) communicate with the subsequent reactor (23) or the settling chamber (20a) so that effluent of the biofilter units (1a, 1b) can flow into the subsequent reactor (23) or the settling chamber (20a).
A water treatment facility using a biofilter unit, wherein one or more biofilter units (1) of any one claim of 1 to 7 are disposed at an upper surface of a reactor (30) comprised of an influent water inlet (31) and a clarified effluent outlet (32) and where physiochemical or biological reaction occurs, and a clarified effluent passage (7) of the biofilter unit (1) communicate with the clarified effluent outlet (32) of the reactor (30) so that effluent of the biofilter unit (1) can be discharged to an outside via the clarified effluent outlet (32).
