摘要
A removal apparatus of non-point source pollutants for a rainwater drain pipe is provided to prevent the pollution of a river by removing various pollutants contained in initial rainwater discharged together with various pollutants of a road surface and draining off rainwater smoothly after moving the pollutants. A removal apparatus of non-point source pollutants for a rainwater drain pipe includes an integral filter device connected to the bottom of a water collection pipe(200) by fastening members(240,241) and equipped with an inner water collection pipe(201), a precipitation box(270), a filter(220) and a drain filter(291) to let rainwater flow in the inner water collection pipe, to settle solids in the precipitation box and to remove pollutants of initial rainwater through the filter, and then to discharge superior rainwater, an impact prevention net(210) installed between the integral filter device and the fastening member to relieve the impact of rainwater, a discharge pipe(300) installed to the upper part of the water collection pipe to discharge rainwater smoothly if the rainwater is filled in the water collection pipe due to the lowering of efficiency of the filter, and a flow control plate(310) installed to the discharge pipe connected to the upper part of the water collection pipe to prevent initial rainwater from scattering to the discharge pipe while dropping from a drain pipe(100) to the water collection pipe, thereby to prevent the pollutants contained in the initial rainwater from discharging to a river effectively.
