摘要

The filter material for water purification of eutrophication contaminated water according to the present invention is an average particle size having a microporous structure as a whole by oxidizing ash from low-grade coal that is not suitable for use as fuel. Is a granular material of activated coal having a diameter of 5 mm or more, and an activated coal granular material in which the ratio of silicon and carbon in the component elements is regulated within a predetermined range is used. As a result, eutrophied contaminated water that effectively uses the excellent ability of activated coal particulate material obtained by oxidizing low-grade coal at low cost, the ability to purify microorganisms, and the ability of plants to absorb nitrogen and phosphorus. It is possible to provide a filtering material for water purification and a water purification facility using the same.
