APPARATUS FOR REMOVAL OF NONPOINT SOURCE POLLUTION USING A HYDRODYNAMIC FILTER SEPARATOR

摘要

The present invention relates to an improved type of non-point source removal device having a filter mounted directly inside a hydrodynamic separator (HDS; Hydrodynamic Separator), the cylindrical swirl flow chamber (10) for rotating the influent; An inlet 20 formed at one side of the swirl flow chamber 10 and having an inflow water therein; A filter chamber 30 extended with the swirl flow chamber 10 on the swirl flow chamber 10; A filter cartridge 40 mounted inside the filter chamber 30; A filter 50 accommodated inside the filter cartridge 40; A treatment water discharge part 60 formed at one side of the filter chamber 30 and discharged from the treatment water; A central shaft 70 supporting the filter cartridge 40 and removing air bubbles; A float trap 80 installed at one side of the filter chamber 30 to discharge the float in the treated water to the outside; It is formed on the upper side edge of the filter chamber 30, the overflow water discharge portion 90 for overflowing the influent in case of; According to the non-point source removal apparatus using the hydrodynamic filtration separation method according to the present invention, the particle separation efficiency of the non-point contaminants is improved, and the life of the filter is improved, the equipment by forming the swirl flow chamber and the filter chamber integrally formed in the same container It can reduce the required area.
