摘要：
In this study, pretreatment of oily sludge, was carried out by Wet Air Oxidation (WAO) process. Experiments were conducted to see the effects of temperature, the initial COD, residence time, concentration of catalyst and OE (O-2 excess) on the oxidation of the oily sludge. The results showed that in the WAO 88.4% Chemical Oxygen Demand (COD) was achieved after 9min. COD removal was 92.7% in the Catalytic Wet Air Oxidation (CWAO) over Na2CO3 catalyst. The results proved that the CWAO was an effective pre-treatment method for the oily sludge.
