Open publisher page 1 citations

Abstract

The organic wastewater taken from a company in Jiangsu Province is treated through the wet air oxidation technology.The results show that at the condition of 250℃,Po2=3.5 MPa,reaction time of 2h and diluted multiples of 0.5 times(COD=100 000 mg/L around),the removal rate of COD was 56%,the BOD/COD increased to 0.63 and the biochemical nature of wastewater was improved greatly,thus providing a good condition for the successive biological treatment.
