PURPOSE: A non-point pollutant processing unit is provided to improve the water quality discharged after the non-point pollutant treatment by increasing the amount of dissolved oxygen in rainwater through a vortex. CONSTITUTION: A non-point pollutant processing unit comprises a first partition plate(100), a second partition plate(200), and a third partition plate(300). The first partition plate partitions the upper space on a precipitation unit, and forms a passage on a lower space for holding floating substances in rainwater flowed from an inlet(10). The second partition plate is installed on the lower side of the inlet opposed to the first partition plate, and the lower side of the second partition wall is bent upwards to form a vortex by disturbing the flow of the rainwater which moves from the upper side to the lower side. The third partition plate passes through the lower space of the first partition plate while partitioning the lower space of the precipitation unit, and is bent downwards to form a vortex disturbing the flow which moves from the lower side to the upper side. |
