Eco-friendly Filtration Grit Chamber AND Rain Water Recirculation System Using Thereof

摘要

The present invention relates to an eco-friendly filtering water catchment and a rainwater recirculation system using the same. The present invention includes: a purification collecting well (350) installed in a green belt, a residence area, a factory, a commercial area, or a road to primarily filter rainwater by collecting the rainwater from the ground; a filtering water catchment (100) connected from the purification collecting well (350) to a rainwater inflow pipe (310) to secondarily filter the rainwater, and including a water tank block (110), a filtering block (120) installed on the water tank block (110), a filter (130) installed in a floor part (122) of the filtering block (120), an inflow tank block (200) installed in the upper part of the filtering block (120), and an outlet (212) and a cover (216) covering and blocking the upper surface of the inflow tank block (200); a rainwater tank (400) connected to the filtering water catchment (100) through a rainwater discharge pipe (150) to store water filtered in the filtering water catchment (100); a distributing duct (510) delivering the water, stored in the rainwater tank (400), to the ground; and a rainwater pump (500) connected to the distributing duct (510) to pump up the water, stored in the rainwater tank (400), to the ground. The water and rainwater, used as urban environment water or water for living, are collected into the purification collecting well (350) to be primarily filtered and then secondarily filtered in the filtering water catchment (100), and the secondarily filtered rainwater is stored in the rainwater tank (400) and then reused as urban environment water or water for living.
