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

使用一种具有高活性表面积/体积比的特殊类型的反应器，研究通过光电催化过程从气田采出水中降解有机污染物的情况。GC-MS分析表明，该废水中有50多种有机物质。因此，化学需氧量被认为是研究的目标参数。用于降低废水的高TDS的简单蒸发工艺将其电导率从 6300μS/ cm降低到 1100μS/ cm，同时初始COD同时从9500  mg / L降低到750  mg / L。使用盘管式微反应器通过光电催化过程再次处理蒸发过程中产生的蒸馏废水，其COD降至143 毫克/升 在本研究中，代替光电化学中常用的半导体，如TiO ₂，氮化硼碳（BCN）纳米片被用作光催化剂。调查不同参数对COD去除率的影响表明，在停留时间得到最大的COD去除率（81％）15 分钟，pH值 =  3，施加的电池电压20 伏，导电率 =  2500  μS/厘米和H ₂ ö ₂浓度为 8mM。
