SYSTEM FOR TREATING A RIVERBANK FILTRATION ON SITU BY USING AN INCLINED INJECTION PIPE

摘要

The present invention relates to an on-site treatment system for a riverside filtered water using an inclined injection pipe, to inject oxygen water in high injection efficiency by efficiently reducing concentration of iron or manganese in underground water collected by a riverside water collecting system even if multiple vertical injection wells (or vertical wells) passing through the bottom of a river to inject the oxygen water onto a river bottom area are not installed. The on-site treatment system for a riverside filtered water using the inclined injection pipe includes: the vertical collecting well, one or more horizontal collecting pipes, and one or more inclined injection pipes. The vertical collecting well is vertically installed on the ground surface around the riverside water. The horizontal collecting pipe includes: one end unit connected to an outer wall of the vertical collecting well; and the other end unit formed in a radial form to the outside of the vertical collecting well. A path of the filtered riverside water is connected to the vertical collecting well. The inclined injection pipe includes: one end unit adjacent to the vertical collecting well; and the other end adjacent to the other end unit of the horizontal collecting pipe. So, the inclined injection pipe is arranged to be inclined toward the other end unit of the horizontal collecting pipe and injects the oxygen water provided from the outside to the ground.
