摘      要：The paper presents results of phenol oxidized under the conditions of high temperature created during collapse of cavitation *** degradation efficiency has been greatly improved by using cavitation water jets combined with H2O2 as demonstrated in laboratory *** factors affecting phenol removal ratio were ex-amined and the degradation mechanism was revealed by high performance liquid chromatography(HPLC).The re-sults showed that 99.85% of phenol was mineralized when phenol concentration was 100 mg·L-1 with pH value of 3.0,H2O2 concentration of 300 mg·L-1,confining pressure of 0.5 MPa,and pumping pressure of 20 *** in-termediate products after phenol oxidation were composed of catechol,hydroquinone and ***,phenol was degraded into maleic acid and acetic ***,a dynamic model of phenol oxidation via cavi-tation water jets combined with H2O2 has been developed.
