Research on the Treatment of Ammonia Nitrogen in Groundwater by Electrochemical Technology
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.
