PURPOSE: A device for separating initial rainwater is provided to improve the efficiency of sewage disposal facilities by enabling initial rainwater with multiple non-point pollutants to be separated. CONSTITUTION: A device for separating initial rainwater comprises an initial rainwater separation unit(10), a first screen(11), a water control unit(20), an initial rainwater collection unit(30), and a blocking unit. The initial rainwater separation unit is formed on the inner surface of a rainwater tank(100). The first screen is formed on the top of the initial rainwater separation unit and separate foreign materials from the rainwater tank. The water control unit receives rainwater and gradually discharge the rainwater through a filter(22). The initial rainwater collection unit temporarily stores rainwater when the rainwater exceeds the processing capacity of the water control unit. When the rainwater exceeds the processing capacity of the initial rainwater collection unit, the blocking unit blocks rainwater supplied from the initial rainwater separation unit. |
