电芬顿技术处理印染废水的研究

摘要

To deal with the dyeing wastewater effectively, this paper focused on the eletro-Fenton process and make a study of decoration dyeing wastewater contained rhodamine B. Results showed that the best factors were initial pH=3, air 0.3 L/min, the electrolysis volt-age of 8 V, current density 40 mA/cm2 , FeSO4 concentration of 15 mmol/L, electrolytic 45 min.%为降解印染废水中的有机物,利用电芬顿技术对印染废水降解进行了研究.实验结果表明,电芬顿处理实际工程印染废水的最佳降解条件为初始pH值3、曝气量为0.3 L/min、电解电压为8 V、电流密度为40 mA/cm2、FeSO4浓度为15 mmol/L、电解45 min.
