A continuous baffle flow electrocatalytic oxidation device, using porous Ti4O7 anodes prepared through vacuum plasm spraying technology, was developed to achieve the effective degradation of sulfamethoxazole (SMX) in wastewater. The effects of operation conditions on SMX degradation efficiency were examined, the energy consumption and the stability of the system were assessed in the treatment of actual wastewater. The possible electrocatalytic degradation mechanism of SMX was also proposed. SMX removal efficiency, energy consumption, mineralization efficiency and mineralization current efficiency could reach at 82.0%, 13.1kWh/m3, 34.2% and 0.7%, respectively, at the initial SMX concentration of 10mg/L, Na2SO4 concentration of 5mmol/L, current density of 5mA/cm2, and solution velocity of 27mL/min. The primary degradation mechanism of SMX was indirect oxidation, and the contribution efficiencies of ·OH and were 76.2% and 5.8%, respectively. The dominant degradation pathways were hydroxylation, N-S bond cleavage, oxidation and coupling reactions. The device exhibited good stability during the long-term treatment of both experimental and actual wastewaters, with SMX degradation efficiency, TOC removal efficiency, and COD removal efficiency in actual wastewater reaching 100%, 19.8%, and 72.2%, respectively. The electrocatalytic oxidation device effectively degraded SMX, and it also reduced the toxicity. Therefore, the continuous baffled flow electrocatalytic oxidation device based on the porous Ti4O7 electrode can effectively eliminate SMX from wastewater.

通过真空等离子体喷涂技术成功制备多孔Ti4O7电极,并构建连续折流式电催化氧化装置,以实现水中磺胺甲恶唑(SMX)的有效降解.考察了操作条件对SMX降解效率的影响,计算了体系能耗,并评估了系统的稳定性和实际废水处理效果,同时推测了SMX的电催化降解机理.结果表明,在10mg/L SMX初始浓度、5mmol/L电解质浓度、5mA/cm2电流密度、27mL/min溶液流速的反应条件下,连续折流式电催化氧化装置对SMX的去除效率可达82.0%、降解能耗13.1kWh/m3、矿化效率34.2%、矿化电流效率0.7%.SMX的主要降解机理为间接氧化,·OH和在SMX降解反应中的贡献效率分别为76.1%和5.8%,其主要降解路径主要为羟基化、断键、氧化和耦合,最终生成小分子物质.对实验配水和实际废水的长期处理过程中表现出良好的SMX降解性能和运行稳定性,实际废水中SMX去除效率、TOC去除效率和COD去除效率等分别为100%、19.8%、72.2%,且经过电氧化处理后废水毒性降低.因此,基于多孔Ti4O7电极的连续折流式电催化氧化装置可实现对水中SMX的有效去除.

通过真空等离子体喷涂技术成功制备多孔Ti4O7电极,并构建连续折流式电催化氧化装置,以实现水中磺胺甲恶唑(SMX)的有效降解.考察了操作条件对SMX降解效率的影响,计算了体系能耗,并评估了系统的稳定性和实际废水处理效果,同时推测了SMX的电催化降解机理.结果表明,在10mg/L SMX初始浓度、5mmol/L电解质浓度、5mA/cm2电流密度、27mL/min溶液流速的反应条件下,连续折流式电催化氧化装置对SMX的去除效率可达82.0%、降解能耗13.1kWh/m3、矿化效率34.2%、矿化电流效率0.7%.SMX的主要降解机理为间接氧化,·OH和在SMX降解反应中的贡献效率分别为76.1%和5.8%,其主要降解路径主要为羟基化、断键、氧化和耦合,最终生成小分子物质.对实验配水和实际废水的长期处理过程中表现出良好的SMX降解性能和运行稳定性,实际废水中SMX去除效率、TOC去除效率和COD去除效率等分别为100%、19.8%、72.2%,且经过电氧化处理后废水毒性降低.因此,基于多孔Ti4O7电极的连续折流式电催化氧化装置可实现对水中SMX的有效去除.

A continuous baffle flow electrocatalytic oxidation device, using porous Ti4O7 anodes prepared through vacuum plasm spraying technology, was developed to achieve the effective degradation of sulfamethoxazole (SMX) in wastewater. The effects of operation conditions on SMX degradation efficiency were examined, the energy consumption and the stability of the system were assessed in the treatment of actual wastewater. The possible electrocatalytic degradation mechanism of SMX was also proposed. SMX removal efficiency, energy consumption, mineralization efficiency and mineralization current efficiency could reach at 82.0%, 13.1kWh/m3, 34.2% and 0.7%, respectively, at the initial SMX concentration of 10mg/L, Na2SO4 concentration of 5mmol/L, current density of 5mA/cm2, and solution velocity of 27mL/min. The primary degradation mechanism of SMX was indirect oxidation, and the contribution efficiencies of ·OH and were 76.2% and 5.8%, respectively. The dominant degradation pathways were hydroxylation, N-S bond cleavage, oxidation and coupling reactions. The device exhibited good stability during the long-term treatment of both experimental and actual wastewaters, with SMX degradation efficiency, TOC removal efficiency, and COD removal efficiency in actual wastewater reaching 100%, 19.8%, and 72.2%, respectively. The electrocatalytic oxidation device effectively degraded SMX, and it also reduced the toxicity. Therefore, the continuous baffled flow electrocatalytic oxidation device based on the porous Ti4O7 electrode can effectively eliminate SMX from wastewater.
