摘要:
构建了一种电还原-电氧化耦合电化学系统，评估了其处理膜浓缩液的脱氮、除碳和解毒效能。在运行时间为3 h、电流密度为20 mA/cm2条件下，耦合电化学系统对TOC的去除率为（68.4±1.5）%，对TN的去除率为（42.7±1.7）%，较同步还原氧化系统分别提升42.8和32.4个百分点。该耦合电化学系统避免了氧化活性自由基与还原活性自由基的相互消耗、抵消，实现了还原与氧化作用的协同增效。同时，耦合电化学系统还原路径的有效发挥，实现了氧化氯化副产物的还原脱氯，显著强化了系统解毒效能，可使发光细菌抑制率从（57.6±2.0）%进一步降至（28.7±1.4）%。此外，直接还原脱氮（NO3-至N2）与直接氧化脱氮（NH4+至N2）的循环往复交替，也促进了脱氮效能的显著增强。TOC与TN协同去除效能的有效强化也进一步削减了废水的生物急性毒性。因此，该耦合电化学系统可用于高盐膜浓缩废水处理。
Abstract:
A coupled electroreduction-electrooxidation electrochemical system was constructed, and its performance in treating membrane concentrate was evaluated in terms of nitrogen removal, carbon removal, and detoxification. After 3 hours of operation at a current density of 20 mA/cm2, the removal rates of TOC and TN by the coupled electrochemical system were (68.4±1.5)% and (42.7±1.7)%, respectively, which were 42.8 percentage points and 32.4 percentage points higher than those of the simultaneous redox system. The coupled electrochemical system avoided mutual depletion and counteraction between oxidizing and reducing active radicals, achieving a synergistic effect between reduction and oxidation. Meanwhile, the effective functioning of the reduction pathway enabled the reductive dechlorination of oxidized chlorinated by-products, significantly enhancing the detoxification efficiency of the system and further reducing the inhibition rate of luminescent bacteria from (57.6±2.0)% to (28.7±1.4)%. Furthermore, the alternating cycle of direct reduction for TN removal (NO3- to N2) and direct oxidation for TN removal (NH4+ to N2) also significantly promoted nitrogen removal efficiency. The enhanced synergistic performance of TOC and TN removal further reduced the bio-acute toxicity of the treated wastewater. Therefore, this coupled electrochemical system can be used for the treatment of high-salinity membrane concentrate wastewater.
