PURPOSE: A non-point pollution disposal system for initial rainwater is provided to separate and purify initial rainwater with non-point pollutants. CONSTITUTION: A non-point pollution disposal system for initial rainwater comprises an initial rainwater separation unit(10), a first screen(11), a nonpoint purification unit(20), an initial rainwater collection unit(30), a blocking unit, a drain pipe(71), and a rain tank(72). The initial rainwater separation unit is arranged on the inner surface of a rainwater tank(100). The first screen is arranged on the top of the initial rainwater separation unit and separates foreign materials. The nonpoint purification unit has a filter(22). When initial rainwater exceeds the processing capacity of the nonpoint purification unit, the initial rainwater collection unit temporarily stores the rainwater. The blocking unit blocks the initial rainwater supplied from the initial rainwater separation unit. |
