PROBLEM TO BE SOLVED: To efficiently treat organic materials, such as harmful chemical materials dissolved in water, contaminants and sludge, to render these materials harmless. SOLUTION: Within a running water pipeline configuring a water treatment apparatus, a Venturi tube 4 consisting, successively from the upstream side, of a throttle section, a throat section and a diffuser section is installed. From the inlet of the throttle section of the Venturi tube 4 toward the upstream side, an oxidative solution inlet 5 is provided at a position apart by≥3 times the inner diameter of the inlet. The water treatment apparatus is operated under conditions such that the static pressure in the throat section of the Venturi tube is kept at a saturated steam pressure or below and cavitation is generated on the downstream side from the throat section.
