Document Type and Number:
WIPO Patent Application WO/2011/099656
Kind Code:
A1
Abstract:
The present invention relates to a downflow high-speed fine filtering apparatus for wastewater, the apparatus comprising a jacket-shaped outer container member (2) defining a space therein for storing water, having a filtering raw water supply pipe (21) formed at one side thereof for supplying filtering raw water from the top of a filtering member (82) configured as a weft, and having a reverse wash water discharge pipe (16) formed on the other side thereof for discharging reverse wash water and air for reverse washing, wherein the downflow high-speed fine filtering apparatus further comprises: a fluid discharge guide plate (26) at the upper portion of the outer container member (2), for guiding the discharge of reverse wash water through a central portion of an inner container member (23) during reverse washing; the inner container member (23) disposed within the outer container member (2) and having the filtering member (82) configured as a weft installed therein; a multifunctional porous plate (24) at a lower portion of the inner container member (23), for performing the functions of discharging filtered water and supplying reverse wash water and air for reverse washing; a multifunctional member (4) in communication with the bottom of the inner container member (23) and having a running-water collector (43) installed therein; a running-water collector main pipe (6) connected to the bottom of the multifunctional member (4), for discharging filtered water; a reverse wash water supply pipe (7) connected to a side of the running-water collector main pipe (6), for supplying reverse wash water; and a reverse washing air supply pipe (9) connected to the other side of the running water collector main pipe (6), for supplying air for reverse washing.
