摘要：
SCWO and electrochemical process of oily wastewater were investigated. The Ti/CeO2 electrode was prepared by electrodeposition technique and applied to treat oily wastewater via electrochemical oxidation. The results show temperature imposes a great impact on electrochemical oxidation of oily wastewater. Under the optimal condition, the COD removal of reached 55.30%. More than 80% chemical oxygen demand (COD) removal from oily wastewater was achieved using NaHCO3 catalytic SCWO under the following conditions using a 0.7 L batch reactor: temperature is 320 degrees C and concentration of NaHCO3 is 100 mg/L. 99.62% of COD removal was achieved. BOD5/COD ratio is now 0.56.
