PURPOSE: A device for processing initial rainwater of road inlet using a nonwoven filter is provided to improve flux box and ability compared to other filter type due to hydraulic conductivity and induce the processing water flow into natural flow by water level, thereby having excellent contaminant adhesive ability and managing economical maintenance and having excellent wide usage. CONSTITUTION: A device for processing initial rainwater of road inlet using a nonwoven filter is comprised of road inlet well(12), a processor(28), a casting lid(30), a steel grating(32), a division plate(34). The road inlet well has a single projection part(9) in upper part of body. The processor(28) is comprised of chamber where nonwoven filter(26) is filled in one side inside the body and a detritus tank. The processor is inserted into the road inlet well. The flange is formed in upper part of the body and is located in upper surface of single projection part of the road inlet well. A partition wall(16) is installed in vertically downward direction in center part of the body. An initial rainwater inlet(18) is formed in upper part of the partition wall. Along the upper part of the wall surface of body, overflow hole is formed in predetermined interval for rainwater to go out when rains heavily. The casting lid has a through-hole in center part. The steel grating has a through-hole having predetermined interval but is placed in upper surface of the casting lid. |
