Electrochemical treatment can solve the problems arising due to effluents and offer an effective alternative to the existing methods. An undivided static electrolyser was charged with distillery effluent and the organics were oxidized electrochemically. Anodized graphite plate anodes and graphite cathodes were used for the treatment of distillery effluent. The effect of pH and current density on the treatment was studied. Sodium fluoride, sodium chloride and sodium bromide were chosen as electrolyte and their influence was found out. Complete decolorization has been observed in all cases. A maximum of 93.5% of biological oxygen demand reduction, 85.2% of chemical oxygen demand reduction and 98.0% absorbance reduction were obtained in the presence of sodium chloride as supporting electrolyte. Probable mechanism was also proposed for the oxidation of organics present in the effluent.
电化学处理可以解决废水产生的问题，并为现有方法提供一种有效的替代方案。一个未分隔的静态电解槽装入酿酒厂废水，有机物通过电化学方式被氧化。采用阳极氧化石墨板阳极和石墨阴极来处理酿酒厂废水。研究了pH值和电流密度对处理效果的影响。选择氟化钠、氯化钠和溴化钠作为电解质，并研究了它们的影响。在所有情况下均观察到完全脱色。在以氯化钠作为支持电解质的情况下，生物需氧量最多降低了93.5%，化学需氧量最多降低了85.2%，吸光度最多降低了98.0%。还提出了废水中有机物氧化的可能机理。
