    Abstract：Cavitating water jet flow is a new type of jet flow in which such course as air bubble generation，growing up and burst will occur when pressure at certain point in the jet flow field drops down below the saturated steam pressure，air bubble burst will result in instant high temperature and high pressure phenomenon and generate such strong oxidation materials as H+，OH+，etc. Effects of water jet cleaning，derusting and crushing and metal surface properties can be improved through such high temperature，high pressure，micro jet and other physical effects. Through mechanical shear，pyrolysis，radical oxidation，supercritical water oxidation and other chemical effects，chemical degradation can be conducted to organic matters with nonbiodegradable toxicity. Cavitating water jet has wide application prospects in such field as oil industry，mining industry and environmental protection.
