INFILTRATION SYSTEM WITH CLEANING SYSTEM USING RIVERBED FILTRATION

摘要

A catchment system using a riverbed filtration process having cleaning facilities is provided to lower concentrations of iron and manganese contained in filtered water and maximize the removal of organic matters by supplying oxygen and saturating a soil layer in the riverbed with oxygen, thereby oxidizing iron and manganese. In a catchment system(100) using a riverbed filtration process having cleaning facilities including: a horizontal catchment pipe installed by digging a riverbed; and a catchment well(110) for transferring the river water onto the ground by raising river water of which quality has been improved through alluvium of a riverbed through the horizontal catchment pipe, the catchment system using the riverbed filtration process having the cleaning facilities comprises: a cleaning part(120) installed on a top part of the catchment well to clean the horizontal catchment pipe; an air injection pipe(130) which is installed in the catchment well, which surrounds an inner peripheral surface of the catchment well, and which has an air diffuser formed on a surface thereof to remove odor and organic matters in the catchment well; and one or more air pipes which are installed outside the catchment well, which surround the catchment well in the same direction as the length direction of the catchment well, and which have holes formed in surfaces thereof.
