PURPOSE: A natural infiltration trench type nonpoint pollution reduction facility using recycling water is provided to efficiently remove pollutants from a pollution source and to maximize the removal of pollutants. CONSTITUTION: A natural infiltration trench type nonpoint pollution reduction facility using recycling water comprises a first pollution reduction unit(200), a second pollution reduction unit(300), a first bypass pipe(400), a second bypass pipe(500), a treatment tank(600), and a power supply unit(800). The first pollution reduction unit is connected to an inflow pipe(100) and primarily removes twigs and mud flowing with rainwater. The second pollution reduction unit includes an adsorption layer, a rubble layer, and a gravel layer. The first bypass pipe re-filters the rainwater primarily filtered by the first pollution reduction unit in the second pollution reduction unit. The second bypass pipe transfers the rainwater flowing into the first pollution reduction unit to the treatment tank. The treatment tank collects the rainwater not filtered by the first pollution reduction unit and discharges the rainwater externally when the amount of collected rainwater is more than a set of the collected amount. The power supply unit drives a pump installed inside the treatment tank, thereby inputting again the rainwater inside the treatment tank to the second pollution reduction unit. |
