摘要：工业生产过程中存在大量的废冷和废热资源,基于塞贝克效应可利用废冷和废热资源构建温差发电系统。然而,该TEG产生的低压电能如何应用仍存在挑战。本实验开展了温差发电驱动电沉积高效净化电镀行业、集成电路行业与能源行业持续增长的低浓度含铜废水的实验研究。首先探究了TEG系统的稳定性,其中系统在ΔT=130℃时最大功率为0.36 W。通过对温差和流速等参数进行优化,得到温差电池耦合电沉积系统去除含铜废水的最佳参数:ΔT=90℃、两异侧进水、流速为20 mL·min^(-1)、铜离子初始质量浓度为500 mg·L^(-1)和电极间距为0.7 cm。在最优参数条件下,电沉积60 min后,铜离子去除率达到99.42%,电流效率为67.93%。TEG与电沉积系统能量转化效率为36.96%。利用该体系处理实际含铜废水100 min后,去除率可达95.83%。此外,通过SEM、XRD和XPS对电沉积产物进行分析,结果表明该产物由金属铜和氧化亚铜的复合相组成,其中金属铜占比约60%。该研究为工业废冷废热资源化利用和重金属废水高效处理提供了参考方案。
Industrial production processes generate significant amounts of waste cold and waste heat,which can be utilized through the Seebeck effect to construct thermal gradient power generation(TEG)systems.However,a key challenge remains in determining how to effectively utilize the low-voltage electricity generated by such thermoelectric device.This study employs thermoelectric generation to drive electrodeposition for wastewater treatment,specifically targeting low-concentration copper-containing wastewater from the rapidly expanding electroplating,integrated circuit,and energy sectors.First,the stability of TEG system was investigated,with the system achieving a maximum power of 0.36 W atΔT=130°C.By optimizing parameters such as temperature difference and flow rate,the optimal parameters for the thermoelectric battery-coupled electrodeposition system to remove copper-containing wastewater were determined to beΔT=90°C,counter-current flow,flow rate of 20 mL·min-1,initial copper ion mass concentration of 500 mg·L^(-1),and electrode spacing of 0.7 cm.Under these optimal conditions,after 60 minutes of electrodeposition,the copper ion removal rate reached 99.42%,with a current efficiency of 67.93%.The energy conversion efficiency of TEG and electrodeposition system was 36.96%.Moreover,this system achieved a copper removal rate of 95.83%within 100 minutes when treating real copper-containing wastewater.Additionally,analysis of the electrodeposition products using scanning electron microscope,X-ray diffraction,and X-ray photoelectron spectroscopy revealed that the products consist of a composite phase of metallic copper and copper(I)oxide,with the metallic copper phase accounting for approximately 60%of the total.This study provides a reference for the resource utilization of industrial waste cold and waste heat,as well as the efficient treatment of heavy metal-containing wastewater.
