UNIFIED APPARATUS FOR COHESION AND PRECIPITATION

摘要

Disclosed is an integrated apparatus for cohesion and precipitation. According to an embodiment of the present invention, the integrated apparatus for cohesion and precipitation comprises an in-line mixer having an inlet for a flocculant at a fleet to which wastewater is supplied; and a sedimentation tank connected to the rear end of the in-line mixer in which flocculation and sedimentation reaction of colloidal particles contained in the wastewater supplied through the in-line mixer occurs. The sedimentation tank is connected to the rear end of the in-line mixer to the inside of the tank and comprises: a first inner wall generating a cyclone phenomenon in the wastewater supplied via the in-line mixer; a tube vertically arranged in the inner center of the inner wall; a second inner wall disposed outside the first inner wall to surround the first inner wall and having a second outlet at the lower end; and an outer wall arranged outside the second inner wall to surround the second inner wall and having a supernatant outlet and a sludge outlet respectively formed at the top and bottom of the outer wall.
