NON-POINT CONTAMINANTS PURIFICATION SYSTEM FOR TREATING FIRST RAIN

摘要

PURPOSE: A facility for treating the non-point pollutants of initial rainwater is provided to completely separate and eliminate suspended impurities and grease and to form the generation of vortex by introducing water to a tangential direction. CONSTITUTION: A facility for treating the non-point pollutants includes a screen chamber(100), a filtering chamber, a second partition, and a filtering unit. The screen chamber includes an inlet(130), a cylindrical screen(120), a comb-shaped screen(150), and a drain(140). A rainwater inlet and a treated water outlet are installed at both sides of the screen chamber. The cylindrical screen primarily filters solid materials from rainwater. The comb-shaped screen secondarily filters the primarily filtered rainwater. The second partition connects the screen chamber and the filtering chamber based on the drain. The filtering unit is arranged at the filtering chamber. The filtering unit defines a space between the drain and the outlet.
