The present invention relates to a rainwater utilization and non-point pollutant treatment device. The rainwater utilization and non-point pollutant treatment device comprises: a filtering unit receiving rainwater from a rainwater supply unit, and discharging the rainwater to a rainwater treatment unit by filtering foreign substances contained in the rainwater; a settling tank connected to the filtering unit such that a part of the rainwater supplied from the rainwater supply unit to the filtering unit flows inside, and having a water storage space storing the rainwater in order for the foreign substances contained in the rainwater to be precipitated; an initial rainwater distinguishing unit distinguishing initial rainwater from the rainwater supplied to the filtering unit; and a blocking unit blocking the rainwater discharged to the rainwater treatment unit in the filtering unit, and discharging the rainwater to the settling tank when the rainwater supplied to the filtering unit is distinguished as the initial rainwater wherein the blocking unit is connected to the initial rainwater distinguishing unit. According to the present invention, the rainwater utilization and non-point pollutant treatment device distinguishes the initial rainwater among the rainwater flowing inside, and enables the initial rainwater to flow into the settling tank such that the foreign substances contained in the initial rainwater can be precipitated; thus improving filtering efficiency on the initial rainwater. |
