REDUCING APPARATUS OF NON-POINT SOURCE POLLUTION OF TURVULENT FILTRATION TYPE}

The present invention relates to a vortex filtration type non-point source reducing apparatus, and more particularly, the first screen, the second screen, the first filtration filter and the second filtration filter to provide a purification efficiency of the non-point source contained in the initial rainwater. At the same time, the present invention relates to a vortex filtration type non-point source reduction device that facilitates maintenance of the device.

In general, water sources are divided into point source pollution and non-point pollution sources for the convenience of prevention and management.

Point sources are pollutants that emit wastewater containing pollutants in sewage pipes or ditches in certain areas, such as sewage plants, wastewater treatment plants, power plants, waste mines, oil tanks, oil wells, etc. Since specific pollutants can be separated from the contaminated water, a purification system suitable for the characteristics can be installed.

However, nonpoint pollution sources are pollutants accumulated in the ground, such as urban areas, construction sites, parking lots, roads, etc., along with contaminants accumulated on the surface, flowing down to rivers, lakes, and seas without contaminating water and polluting water quality.

These nonpoint sources usually occur in areas such as parking lots, shopping malls, housing complexes, industrial complexes, etc. during the initial rain, and they do not have specific discharge paths and are generated through unspecified discharge paths. It flows out together and discharges to rivers, etc., and worsens the water quality.

The methods used for the removal of non-point sources are storage type (reservoir tank, pond, artificial wetland), infiltration type (penetration tank, infiltration ditch, pore packing), vegetation type (vegetable filtration unit, vegetation channel), device type (storm filter). , Sand filter, stormceptor, stormgate, etc.), there are economic problems such as the need to install a new treatment site and expensive equipment in order to remove pollutants caused by rainfall using the above facilities. .

In other words, in the case of the storage type, a relatively large amount of land is required, so it is difficult to install due to the rise of land prices in developed areas, and in summer, pests such as mosquitoes and flies are generated, causing health problems. Due to the continuous inflow of suspended solids and contaminants, it is difficult to maintain due to the blockage of voids, and the groundwater is contaminated because it is penetrated into the basement. The vegetation type requires land over a certain size and the vegetation is maintained. Ideal environmental conditions can be required, and the device type has problems such as high installation cost and limited installation location.

As described above, the conventional non-point source reduction apparatus has a problem in that the installation cost of the apparatus is expensive and not easy in terms of maintenance.

Moreover, due to the rapid development of cities, roads, factories, etc., the pollutants caused by rainfall are not directly removed from the rivers, but aquatic plants are dead and water pollution is intensified. There is a difficulty in applying a technique.
