摘要

The present invention relates to a method for manufacturing a filter medium for a nonpoint pollution source, a filter medium for a non-point pollution source thereof, and a filter and apparatus for reducing a non-point pollution source including the same. According to the present invention, bulk, middle, and fine filter media with a different structure and size for a nonpoint pollution source are used for the filter and/or apparatus for reducing the nonpoint pollution source individually or in a combination. Accordingly, the present invention provides advantage of being suitable for filtration for the nonpoint pollution source in initial rainfall, providing high filtration efficiency, and manufacturing the filter medium for the non-point pollution source with an inexpensive material easy to find.;COPYRIGHT KIPO 2020
