电解芬顿法处理三硝基甲苯废水中有机物的研究

摘要

用电解芬顿法处理三硝基甲苯废水,讨论Fe2+添加量、电解电压、处理温度、通氧量与pH值等对有机物去除率的影响.结果表明,Fe2+添加量为15 mg/L,电解电压为6V,处理湿度为50℃,通氧量为100 mL/min及pH =0时,反应3h后,有机物去除率可达93％.%The wastewater produced in TNT preparation is processed by the electro-Fenton method and the effect of Fe2 + addition, electrolytic voltage, process temperature, oxygen flow volume and pH value on the efficiency of organic matter removal are discussed. The results showed that the removal efficiency of 93% can be achieved under the conditions of Fe2+ 15 mg/L, electrolytic voltage 6 V,processing temperature 50℃, oxygen flow volume 100 mL/min and pH = 0 after the reaction of 3 h.
