INITIAL RAINWATER PURIFICATION SYSTEM FROM A NON-POINT SOURCES

摘要

A selective collecting system of initial rainwater from a non-point contamination source is provided to discharge the purified initial rainwater to the river and precluded the river from being contaminated by forcibly passing at least initial rainwater through the initial rainwater storage sump pit and the purification container. A selective collecting system of initial rainwater from a non-point contamination source comprises an overflow manhole(3) connected to flow the rainwater from the sump pit around the non-point contamination source; an initial rainwater storage sump pit(5) receiving/saving the rainwater from the lower side of the overflow manhole; a purification container(11) installed with a filter(9) receiving/purifying the rainwater from the initial rainwater storage sump pit through a connection pipe(7); an overflow rainwater pipe(13) directly connecting the upper side of the overflow manhole and the downstream of the filter of the purification container; and a discharge pipe(15) discharging the rainwater from the upper part of the purification container to the river.
