The emerging pollutant such as metronidazole, chloramphenicol and sulphonamide were utilized for this research. Three-dimensional electrochemical reactor with particle electrodes such as Strychnos potatorum used to treat the above emerging pollutants. Voltage, pH, initial pollutant concentration and the particle electrode concentration were varied and the optimum conditions for the effective removal was found to be at 9 V, 15 grams of particle electrode and 100 mg/L of initial pollutant concentration. The efficiency of removal was found to be 93.68% for metronidazole, 94.56% for chloramphenicol and 94.11 % for sulphonamide under optimum conditions. The air flow was varied to 2 L/min, 3 L/min and 5 L/min, the removal efficiency was found to be 80.24 %, 94.12% and 95.26 % for the above air flow rates. The comparison of adsorption, two-dimensional electrochemical treatment and three-dimensional electrochemical treatment was done and among them, three-dimensional electrochemical treatment was found to be 18.3 % higher when compared to two-dimensional electrochemical treatment The removal efficiency for three-dimensional and two-dimensioanl treatment were found to be 53.74 % and 45.83 % in 60 min.

利用电化学处理和吸附去除水生系统中新出现的污染物:比较分析

本研究利用了新出现的污染物,如甲硝唑、氯霉素和磺胺。具有粒子电极的三维电化学反应器,如马铃薯用于处理上述新兴污染物。电压、pH、初始污染物浓度和粒子电极浓度是变化的,发现有效去除的最佳条件为 9 V、15 克粒子电极和 100 mg/L 初始污染物浓度。在最佳条件下,甲硝唑的去除效率为 93.68%,氯霉素为 94.56%,磺胺为 94.11%。空气流量变化为 2 L/min、3 L/min 和 5 L/min,发现对于上述空气流速,去除效率分别为 80.24%、94.12% 和 95.26%。对吸附、二维电化学处理和三维电化学处理进行了比较,发现其中三维电化学处理为18个。
