SWIRL FILTER DEVICE FOR TREATMENT OF URBAN STORM RUNOFF AND MICROPARTICLES

摘要

Swirl filter device for treating coarse particles and fine particle material in rainfall effluent according to an embodiment of the present invention spirally vortex baffle so that the coarse particles in the rainwater can be separated by the difference in specific gravity by forming an influent rainwater vortex A first filtration tank having an inlet formed of (Vortex Baffle); A screen arranged to be connected to the inlet in the first filtration tank and to remove residual coarse particles in the rainwater introduced through the inlet; A second filtration tank separated from the first filtration tank through a dividing wall formed at a lower portion of the flow path for communicating with the first filtration tank, the second filtration tank having an outlet for outflowing the final treated water to the outside; And a cartridge filter that removes fine particles in the treated water and discharges the final treated water when the treated water discharged to the lower portion of the screen flows into the second filtration tank through the flow path hole.
