PURPOSE: A rainwater recycling system is provided to enable to recycle rainwater by filtering and to eliminate foreign materials by considering properties of the foreign materials contained in the rainwater to enhance efficiency for filtering the rainwater. CONSTITUTION: A rainwater recycling system comprises a first water collection unit(100), a second water collection unit(200), a preprocessing filter(300), a first storage tank(400), a first pump(500), a water filter(600), a second storage tank(700), and a second pump(800). The first water collection unit collects rainwater running down a rooftop, a roof, and an exterior wall etc. in case of raining. The second water collection unit collects the rainwater existing in areas around a building and on the ground in case of raining. The preprocessing filter is connected to the first and second water collection units and eliminates foreign materials of large particles contained in the rainwater collected by the first and second water collection units. The first storage tank is connected to the preprocessing filter and stores the rainwater has passed through the preprocessing filter. The first pump is connected to the first storage tank and pumps the rainwater stored in the first storage tank. The water filter is connected to the first pump and filters the rainwater pumped by the first pump. The second storage tank is connected to the water filter and stores the rainwater filtered by the water filter. The second pump is connected to the second storage tank and pumps the rainwater stored in the second storage tank. |
