FIRST FLUSH STORMWATER TREATMENT SYSTEM OF CATCH PIT FOR BRIDGES USING NON-WOVEN FABRIC

摘要

PURPOSE: An initial rainwater treatment system of a catch basin for a bridge using non-woven fabric is provided to discharge rainwater, in which contaminants are eliminated, into a neighboring water zone. CONSTITUTION: An initial rainwater treatment system of a catch basin for a bridge using non-woven fabric comprises a catch basin(10) of a bridge, a cover(14), non-woven fabric(16), and strings(18). The cover is detachably installed on the top of the catch basin and flows rainwater into the catch basin. The non-woven fabric is inserted between the top of the catch basin and the bottom of the cover and filters nonpoint pollutants. The strings are formed in the end of the non-woven fabric and flow the rainwater toward the catch basin.
