Abstract

In this study, an electrochemically coupled micro-electrolytic technology–enhanced soil infiltration system (E-ME-SIS) was proposed to address the problem of the high cost of traditional soil infiltration system (SIS) and the difficulty of removing imidacloprid (IMI) wastewater efficiently by a single treatment process. Micro-electrolytic ceramic substrates (MECS) were prepared from iron, activated carbon, aluminum, and fly ash and combined with an external power source to optimize the electrochemical and micro-electrolytic synergy and investigate their effectiveness in treating IMI wastewater. The results showed that MECS had a rough surface with a specific surface area of 2.682 m²/g, combining strong adsorption capacity (maximum adsorption of 1.149 mg/g) and wear resistance (24 h wear rate of 6.4%). The removal of total nitrogen (TN), total phosphorus (TP), and IMI by E-ME-SIS was stabilized at 99%, 98%, and 98%, respectively, at a current density (CD) of 0.625 mA/cm² and influent C/N (COD/N) = 5. This study significantly enhanced the removal of difficult-to-degrade pollutants by SIS through an electrochemically enhanced micro-electrolysis reaction, which provides an energy-saving and stable technical reference for the efficient treatment of IMI wastewater with a potential for engineering applications.

电化学强化微电解陶瓷基板渗透系统处理吡虫啉废水的研究

本研究针对传统土壤渗透系统（SIS）成本高、单一处理工艺难以高效去除吡虫啉（IMI）废水的问题，提出了电化学耦合微电解技术增强土壤渗透系统（E-ME-SIS）。以铁、活性炭、铝和粉煤灰为原料制备微电解陶瓷基板（MECS），并与外部电源结合，优化电化学和微电解协同作用，考察其处理IMI废水的效果。结果表明，MECS表面粗糙，比表面积为2.682 m2/g，具有较强的吸附能力（最大吸附量为1.149 mg/g）和耐磨性（24 h磨损率为6.4%）。当电流密度（CD）为0.625 mA/cm2，进水C/N (COD/N) = 5时，E-ME-SIS对总氮（TN）、总磷（TP）和IMI的去除率分别稳定在99%、98%和98%。本研究通过电化学强化微电解反应，显著提高了SIS对难降解污染物的去除效果，为高效处理IMI废水提供了节能稳定的技术参考，具有工程应用潜力。
