The invention discloses a municipal administration road rainwater reuse facility based on a bioretention zone system. Through the gradient of a cross slope of a V-type pavement, rainwater runoff on the both sides of a road is aggregated into a bioretention zone, so that the rainwater discharge time is shortened to a certain extent; then absorption of pollutants by plant roots, removal of rainwaterrunoff suspended solids (SS) by the planting soil layer and removal of nitrogen and phosphorus by microorganisms in the planting soil layer are carried out after rainwater enters the bioretention zone, then the rainwater enters an artificial filler layer, and the pollutants are further removed in the artificial filler layer; and the rainwater reaches a gravel layer and is drained into a perforated drainage pipe through the gravel layer to enter an impounding reservoir. The device achieves adjustment of the pavement structure, treatment of the pollutants in the rainwater runoff entering the bioretention zone and stora
