The invention relates to the field of rainwater treatment, and discloses a combined device for treating road runoff rainwater. The combined device comprises a first water tank, a guide chamber and a second water tank. The guide chamber is arranged between the first water tank and the second water tank. A perforated plate is arranged at the upper end of the guide chamber. A micro wet-land unit is arranged on the upper side of the guide chamber. A rainwater strainer is arranged at the top of each of the first water tank and the second water tank. Cobblestones are piled on the rainwater strainers. A mud guard and a guide plate are arranged in the first water tank. A mud collection groove is formed in the bottom of the first water tank. The mud guard is arranged on one side of the mud collection groove and inclines toward one side of the guide chamber. A water outlet is formed in the wall of the second water tank. A water outlet pipe is arranged on the wall, opposite to the water outlet, of the second water tank and is used for being connected with a municipal rainwater pipeline. The combined device has the advantages that discharge of runoff rainwater pollutants can be reduced and runoff volume and runoff peak can be decreased.
