Tunnel transverse passage road surface tiled type longitudinal drainage pipe crystallization accelerating device

The utility model discloses an accelerated crystallization device for a pavement tiled longitudinal drainage pipe of a tunnel transverse passage, which is connected to a tunnel drainage blind pipe and comprises a water inlet device, a spiral-wound reverse osmosis membrane element, a water outlet device and a wastewater collecting device, water flowing into the tunnel drainage blind pipe sequentially flows through the water inlet device and the spiral-wound reverse osmosis membrane element; a concentrated water outlet of the roll-type permeable membrane element is communicated with the wastewater collecting device, and water flowing out of a fresh water outlet of the roll-type reverse osmosis membrane element flows to the tunnel drainage blind pipe through the water outlet device. The tunnel transverse channel pavement tiled longitudinal drainage pipe crystallization accelerating device has the beneficial effects that calcium and magnesium ions which are easy to form crystals in wastewater can be filtered, and
