The treatability study of distillery wastewater by electrochemical (EC) oxidation technique as pretreatment has been carried out. Batch experiments were conducted using stainless steel plates as electrodes to assess the effects of operating parameters such as pH, electrolysis duration (ED) and current density (CD). The EC treatment removed 58% COD at current density 0.12 A cm(-2) and at wastewater pH 3 with 120 min of ED. The BOD to COD ratio increased from 0.25 to 0.76 indicating considerable improvement in wastewater biodegradability. The maximum anodic efficiency and minimum energy consumption observed were 7.44 kg COD h(-1) A(-1) m(-2) and 0.19 kWh kg(-1) COD respectively.
已经开展了采用电化学（EC）氧化技术对酿酒厂废水进行预处理的可处理性研究。使用不锈钢板作为电极进行了批次实验，以评估诸如pH值、电解持续时间（ED）和电流密度（CD）等操作参数的影响。在电流密度0.12 A cm(-2)、废水pH值为3且电解持续时间为120分钟的条件下，EC处理去除了58%的化学需氧量（COD）。生化需氧量（BOD）与COD的比值从0.25增加到0.76，表明废水的生物降解性有了显著改善。观察到的最大阳极效率和最小能耗分别为7.44 kg COD h(-1) A(-1) m(-2)和0.19 kWh kg(-1) COD。
