A vortex treatment apparatus for initial rainwater is provided to intensify precipitation efficiency by forming spiral vanes in the vortex guiding filter net to the vortex rotative direction. A vortex treatment apparatus for initial rainwater comprises a rainwater tank(10), and a vortex guiding filter net(20). The rainwater tank has an inlet(12) and an outlet(14) and receives a receiving part(11). The vortex guiding filter net is arranged in the receiving part, formed with an inlet pipe(22), and formed with a wide-upper and narrow-lower shape. The initial rainwater is flown along the side wall through the inlet pipe to guide the vortex. The vortex guiding filter net is connected with a scum intrusion prevention extension net contacted with the inner wall of the rainwater tank. Spiral vanes(24) are installed in the vortex guiding filter net. A scum collecting part(30) includes a scum discharging pipe(32). The scum collecting part has a skimmer(34). |
