抗生素广泛存在于地表水和地下水中,对水生环境和人类健康构成了严重威胁,已成为国际公约管控的重要新污染物。高级氧化技术是处理难降解新污染物的有效技术。基于电化学-过硫酸盐的高级氧化技术在抗生素等新污染物治理中受到了广泛关注,但传统铁阳极活化方法仍存在污泥产量大等缺陷。因此,本研究开发了基于铁阴极电化学活化过硫酸盐(PDS)的高级氧化技术,并研究了其对抗生素(四环素)的降解动力学和机理。研究建立了四环素降解的多过程耦合动力学理论模型,模型模拟结果与实验数据基本吻合,结果表明铁阴极体系能高效降解四环素(0.42±0.007 38 M~(-1) ·s~(-1))并降低电极损耗。通过对主控因子的解析,发现PDS浓度、电流大小、初始pH值、初始四环素浓度均能不同程度影响四环素的降解动力学。通过对降解机制研究,发现铁阴极体系中的主要活性氧物种为·SO_4~-和·OH,它们对四环素降解的贡献分别为28.02%和71.98%。研究结果为应用铁阴极-过硫酸盐技术高效治理抗生素等新污染物提供了重要支撑。 |

Antibiotics are widely present in surface water and groundwater,posing a serious risk to aquatic environments and human health,and have become important new pollutants under international conventions.Advanced oxidation technologies are effective for treating refractory new pollutants.The electrochemical activation of persulfate-based advanced oxidation technology has received widespread attention in the treatment of antibiotics and other new pollutants,but traditional iron anode activation methods still suffer from high sludge production and other deficiencies.Therefore,this study developed an advanced oxidation technology based on the electrochemical activation of peroxydisulfate (PDS) using an iron cathode,and investigated its degradation kinetics and mechanisms on tetracycline.The study established a multi-process coupled kinetic theoretical model for tetracycline degradation,and the simulation results were in good agreement with the experimental observations.The results indicated that the iron cathode system could effectively degrade tetracycline (0.42±0.007 38 M~(-1)·s~(-1)) and reduce electrode losses.Through the analysis of key factors,it was found that sulfate concentration,current magnitude,initial pH value,and initial tetracycline concentration could all affect the degradation kinetics of tetracycline to varying degrees.Inspection of degradation mechanisms revealed that the main active oxygen species in the iron cathode system were ·SO_4~- and ·OH,contributing 28.02% and 71.98%,respectively,to the degradation of tetracycline.These findings provide important support for the efficient treatment of antibiotic and other new pollutants using the iron cathode-persulfate technology. |
