In the search for greener treatment technologies, this work studies the coupling of a wind turbine energy supply with an electrolytic cell (CWTEC device) for the remediation of wastewater polluted with pesticide 2,4-dichlorophenoxyacetic acid (2,4-D). The discontinuous and unforeseeable supply of energy is the main challenge inspiring this new proposal, which aims at reducing the environmental impact of electrolytic treatment by using a green energy supply. The results obtained using the coupled technologies are compared with those obtained by powering the electrolyser with a traditional power supply with a similar current intensity. The mineralisation of wastewater can be accomplished independently of how the electrolytic cell is powered, although differences in performance are clearly observed in the total organic carbon (TOC) and 2,4-D decays. These changes can be explained in terms of the changing profile of the current intensity, which influences the concentrations of the oxidants produced and thereby the mediated electrolytic process.
在寻找更环保的处理技术的过程中,本工作研究了将风力涡轮机能源供应与电解槽(CWTEC 装置)耦合,以修复受农药 2,4-二氯苯氧乙酸(2,4-D)污染的废水。能量的不连续和不可预见的供应是激发这一新提案的主要挑战,该提案旨在通过使用绿色能源供应来减少电解处理的环境影响。使用耦合技术获得的结果与通过使用具有相似电流强度的传统电源为电解槽供电获得的结果进行了比较。尽管在总有机碳 (TOC) 和 2,4-D 衰减方面观察到性能差异,但废水的矿化可以独立于电解槽的供电方式来完成。这些变化可以根据电流强度的变化情况来解释,电流强度会影响所产生氧化剂的浓度,从而影响介导的电解过程。
