A special type of reactor with a high active surface-to-volume ratio was used for investigation of organicpollutants degradation from a gasfield produced water by photoelectrocatalysis process. The GC–MSanalysis showed that there were more than 50 organic substances in this wastewater; therefore, COD wasconsidered as the target parameter for studying. A simple evaporation process used for decreasing highTDS of the wastewater reduced its electrical conductivity from 6300 mS/cm to 1100 mS/cm and also initialCOD decreased simultaneously from 9500 mg/L to 750 mg/L. Distilled wastewater from the evaporationprocess was treated again by the photoelectrocatalysis process using a coil type microreactor, and its CODdropped off to 143 mg/L. Instead of usual semiconductors in photoelectrocatalysis like TiO2, boron carbonnitride (BCN) nanosheets are used as a photocatalyst in this study. Investigating the impact of differentparameters on COD removal efficiency showed that the greatest COD removal efficiency (81%) wasobtained at residence time 15 min, pH = 3, applied cell voltage 20 V, electrical conductivity = 2500 mS/cmand H2O2 concentration of 8 mM.
