Optimization of Electrocatalytic Oxidation Treatment for Chlorine-containing Ammonia Nitrogen Wastewater Using Response Surface Methodology
摘要
Abstract
Electrocatalytic oxidation was adopted to treat simulated chlorinated ammonia nitrogen wastewater.The response surface methodology(RSM)was used to optimize and predict the optimal reaction conditions for electrocatalytic oxidation treatment.Furthermore,the mechanism of ammonia nitrogen removal was explored.The results showed that under the optimal conditions of the initial Cl-concentration of 7 700 mg/L,the initial pH value of 9.7,and the current density of 0.05 A/cm2,the actual removal rates of ammonia nitrogen and total nitrogen were 96.4%and 94.8%after 50 minutes of reaction,respectively,which were close to the values predicted by the model.In the chlorinated system,ammonia nitrogen was mainly removed by the oxidation of active chlorine generated from the anodic reactions.The reaction by-product,nitrate nitrogen was simultaneously reduced to nitrogen gas or ammonia nitrogen at the Cu cathode,achieving efficient and simultaneous removal of ammonia nitrogen and total nitrogen.The research results indicated that the response surface methodology was feasible for optimizing and predicting the process conditions of electrocatalytic oxidation treatment of chlorine-containing ammonia nitrogen wastewater,providing a solution for the subsequent treatment of actual wastewater and industrial applications.关键词
