STORMWATER RUNOFF TREATMENT SYSTEM USING HYBRID-TYPE UPFLOW-FILTER
A rainfall runoff treatment system using a hybrid-type upflow filter is provided in one embodiment of the present invention, comprising: a first mixing motor for receiving runoff containing fine floating materials and driven electrically; a runoff storage tank having a first mixing wheel rotated by the first mixing motor; a second mixing motor for measuring a water level by using a water level adjustment sensor while accommodating runoff introduced from the runoff storage tank by being connected to the runoff storage tank and a first supply pipe, and if the measured water level is lower than a predetermined water level, for driving a water pump installed inside the runoff storage tank to receive runoff and driven electrically; a sidestream storage tank having a second mixing wheel rotated by the second mixing motor; a hydrocyclone for receiving runoff accommodated in the sidestream storage tank according to a driving of a centrifugal pump mounted on a second supply pipe connected to the lower side of the sidestream storage tank and at the same time, receiving a coagulant having a required concentration and aggregating, and condensing at a high speed and then filtering; a coagulant injector for injecting a coagulant having a concentration required for the hydrocyclone; a lower side drain water transfer pipe and a lower side drain water supply pipe for collecting lower side drain water containing a coagulant via a lower port connected to the lower side of the hydrocyclone and thereafter, re-supplying to the upper side of the sidestream storage tank; and an upflow filtering apparatus for receiving runoff from the hydrocyclone via an upper side runoff supply pipe connected to the upper side of the hydrocyclone.
