Non-powered non-point pollution reduction device using circular screen filtration device that can improve river water pollution

摘要

The present invention relates to an apparatus for reducing boiling point pollution, and more particularly, to easily filter foreign substances from contaminated water using a circular screen made of a cylindrical shape, and provide a filtration tank of several stages so that the perforated holes of the circular screen are sequentially reduced. It is easy to filtration according to the size of, and in the final step, it relates to a non-powered non-point pollution reduction device using a circular screen filtration device that can improve water pollution in a river that can improve filtration efficiency by removing fine foreign substances using an adsorption filter. . To this end, a non-powered non-point pollution reduction device using a circular screen filtration device capable of improving water pollution in a river according to an embodiment of the present invention includes a first filtration tank in which non-point contaminated water is introduced to filter impurities, in the first filtration tank. Including a second filtration tank for filtering unfiltered foreign matter from the filtered non-point contaminated water and a third filtration tank for removing residual foreign matter from the non-point contaminated water filtered in the second filtration tank and transferred, wherein the first filtration tank, the second Each of the filtration tank and the third filtration tank has a circular shape, and is provided with a circular screen in which a perforated hole having a small size is sequentially formed.
