FACILITY DECREASING NON-POINT SOURCE POLLUTION FOR RAILWAY FACILITIES

摘要

The present invention relates to a non-point pollution reducing facility that is appropriate in reducing exposure to non-point pollution and reflecting the characteristics of a railway facility, wherein stable non-point pollution removal is performed specifically to a railway facility so as to help the low carbon green growth of the railway industry. Especially, the present invention is to make maintenance of the facility be more convenient. To achieve such purposes, the non-point pollution reducing facility of the present invention includes a concrete block including a pre-treating tank, a filtering tank, and a medium tank. The pre-treating tank has an oil adsorbing screen for adsorbing oil contained in non-point pollution materials. The oil adsorbing screen adjusts the flow speed of rainfall effluent and is installed in the pre-treating tank to adsorb oil contained in non-point pollution materials. The oil adsorbing screen includes an oil adsorbent therein and further includes a cover for replacing the oil adsorbent.
