<P>PROBLEM TO BE SOLVED: To provide a water treatment apparatus for making the gas microbubbles by using a vacuum nozzle to dissolve, in which the vacuum nozzle is prevented from clogging due to suspended matters to operate stably for a long period of time. <P>SOLUTION: The water treatment apparatus includes a pressurizing means that pressurizes water to be treated that contains a gas, the vacuum nozzle that decompresses the water to be treated pressurized by the pressurizing means, a reaction tank into which the water to be treated jetted from the vacuum nozzle is injected, and a three-way valve inserted between the pressurizing means and the vacuum nozzle. The three-way valve is a valve that switches between a route to communicate the water to be treated pressurized by the pressurizing means to the vacuum nozzle and a route to drain the water to be treated that flows backward from the vacuum nozzle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
