The coking wastewater was treated by supercritical water oxidation process.The effects of residence time,reaction pressure on the results of the treatment were investigated and the process conditions of supercritical water oxidation process were optimized.The results showed that when reaction pressure was 28 MPa,residence time was 60 s,reaction temperature was 580 ℃,and oxygen was exceeded 2 to 3 times,the removal rate of CODCr of the wastewater could be over 99.5%.
