An object of the present invention is to provide a surface treatment apparatus which can be easily used and can perform surface treatment excellent in effects such as antifouling and polishing. A surface treatment apparatus (1) includes pressure-resistant containers (15a, 15b) accommodating a large number of granules containing tourmaline powder, and flows water from a water source into the pressure-resistant containers (15a, 15b) to contact the granules and ionize the particles. The pump includes a pump 11 for producing water, and a nozzle 5a for jetting ionized water pressurized by the pump 11 toward a surface to be treated. Further, an ionization flow path 41 that connects the water storage tank 13 for storing water from the water source and the suction side of the pump 11 via the pressure-resistant containers 15a and 15b, and a pressure-resistant container that connects the water storage tank 13 and the suction side of the pump 11 to each other. The three-way switching valve 11 is provided for selectively opening and closing the bypass flow path 40 connected without any intervention. [Selection diagram] Fig. 4 |
