摘要:氧化锡(SnO2)电极在电解处理水性油墨废水领域具有广泛的应用前景。本文首先通过酸析降低水性油墨废水的固体悬浮物(SS)、化学耗氧量(CODcr)和色度,并在使用自制氧化锡电极和添加电解助剂条件下,进行了电流密度、极距以及pH值等条件的优化;然后,对比自制氧化锡电极与常用电极对水性油墨废水电解处理的效果。

Abstract:Tin oxide (SnO2) electrode has a wide application in the electro-oxidation treatment of water-based printing ink wastewater. In this paper, the suspended solid (SS), chemical oxygen demand (CODcr) and color of water-based printing ink wastewater are firstly reduced by acid precipitation. Secondly, current density, pH value and polar distance are optimized under the condition of using home-made tin oxide electrodes and electrolysis additive. Then, the effects of electro-oxidation treatment of water-based printing ink wastewater pared between home-made tin oxide electrode mon electrode.
Keywords: electro-oxidation; water-based printing ink wastewater; chemical oxygen demand; color
前言
水性油墨也称水基油墨或环保性油墨,由水溶性高分子树脂、颜料、溶剂(主要为水)以及相关助剂制备而成。水性油墨废水主要来源于清洗印刷设备过程中的污水排放。例如:洗棍、洗槽、洗桶、冲洗操作间等产生的废水。[1]油墨色彩的千变万化导致其废水的化学成分非常复杂
