    摘要
  • 摘要: 电化学氧化法是一种高效且环保的处理技术,在对包括阿莫西林在内的抗生素的处理上具有显著优势。向传统二维电极反应器中添加活性炭作为粒子电极,能降低系统中传质阻力,提高电流效率。探究了利用三维电极反应器处理阿莫西林模拟废水的最佳工艺,并与传统二维电极反应器和单纯活性炭吸附工艺进行对比。结果表明:三维电极反应器处理阿莫西林适宜条件为石英砂占填充粒子总体积为10%,施加电流密度为5 mA/cm2,电解质为17 mmol/L Na2SO4,溶液初始pH为5.56,此时 TOC去除率为49.1%,阿莫西林去除率为99.0%;且三维电极反应器存在电解和吸附的协同作用,使TOC去除率高于单纯活性炭吸附法和二维电极反应器去除率的加和(49.1%>22.0%+8.7%),具有较好的应用前景。
    Abstract: Electrochemical oxidation is an efficient and environmental-friendly technology with significant advantages in the treatment of antibiotics including amoxicillin. The traditional two-dimensional electrode reactor packed activated carbon as particle electrode will reduce the mass transfer resistance in the system and improve current efficiency. This study explored the optimal conditions for the treatment of amoxicillin simulated wastewater by a three-dimensional electrode reactor, and compared with a two-dimensional electrode reactor and the adsorption process. The optimal conditions were as follows: the quartz sand accounted for 10% of the total volume of the packed particles, the current density was 5 mA/cm2, the electrolyte was 17 mmol/L Na2SO4, and the initial pH of the solution was 5.56. Under the optimal condition, the TOC removal rate was 49.1%, and the amoxicillin removal rate was 99.0%. The synergy between electrolysis and adsorption in the three-dimensional electrodes reactor made the TOC removal rate higher than that of adsorption and traditional two-dimensional electrode reactor (49.1%>22.0%+8.7%), showing a good application prospect.
