摘要：A rain water purifying apparatus for a bridge is provided to preclude the initial rain water and impurities on the bridge from directly falling to the river regardless of the amount of the water by containing the sludge discharge pipe. A rain water purifying apparatus(1) for a bridge comprises a purifying tank(10) having at least one purifying tub and a purifying water discharge pipe extended from the purifying tub to the outside; and a rainfall control pipe unit(20) having a rainfall guide pipe(21) connected to a drain pipe of the bridge, an initial rainfall inlet pipe(23) branched in the purifying tub at the rainfall guide pipe, and a rainfall control valve(25) opening/closing the inlet pipe according to the rise and fall of the water level of the purifying tub. The purifying tub is arranged as a precipitated tub(11) and a filtering tub(15) divided by an overflow wall(13). A sludge discharge pipe(11a) faces the upper surface of the road of the bridge from the lower part of the precipitated tub.
