PROBLEM TO BE SOLVED: To make compact a device, as a whole, by placing a pump for feeding vehicle washing water to tanks and a pump for delivering purified water purified at the tanks to the outside in one outer case, and to reduce the installation space for the outer case and a vehicle washing water recycling device by arranging the tanks and pumps in series in the outer case to easily install the case and the device in a narrow space in a gas station. SOLUTION: In a longitudinally long rectangular box-shaped outer case 60, there are provided in series a coagulating reaction tank 10 into which vehicle washing water 2 is supplied from the outside, a primary filter tank 20, an active carbon tank 30, a secondary filter tank 40, and a suction pump 50 for feeding vehicle washing water to the tank 10 and a feed water pump 51 for delivering washing water 2' from the tank 40 to the outside. A cylindrical first filter 21 of the tank 20 is back-washed by a washing nozzle 24 provided outside the filter 21. A cylindrical second filter 41 of the tank 40 is back-washed by a washing cylinder provided inside the filter 41. |
