摘要
本研究采用电化学氧化技术,针对华东某钢铁企业地下水中的氨氮污染开展中试试验,旨在探索电化学氧化技术在处理氨氮污染地下水中的应用.本文考察了水力停留时间、电流密度和氯离子浓度对氨氮去除效率的影响.试验结果表明,适当的水力停留时间和电流密度对提高氨氮去除效率至关重要,而氯离子浓度在一定范围内对去除效率的提升作用有限.此次试验展现了电化学技术良好的经济性和环境效益,为钢铁企业地下水氨氮的深度治理提供了有效的技术方案和切实可行的实践经验.
Abstract
This study employs electrochemical oxidation technology to conduct pilot-scale experiments on ammonia nitrogen pollution in the groundwater of a steel enterprise in East China,aiming to explore the application of electrochemical oxidation technology in treating ammonia nitrogen-contaminated groundwater.The effects of hydraulic retention time,current density,and chloride ion concentration on the removal efficiency of ammonia nitrogen were investigated.The experimental results indicate that appropriate hydraulic retention time and current density are crucial for enhancing the removal efficiency of ammonia nitrogen,while the role of chloride ion concentration in improving the removal efficiency is limited within a certain range.The experiment demonstrates the good economic and environmental benefits of electrochemical technology,providing an effective technical solution and practical experience for the in-depth treatment of ammonia nitrogen in the groundwater of steel enterprises.
