【摘要】：针对某电厂脱硫废水膜浓缩COD含量高且含少量F-等特点,采用标准三电极电化学体系试验研究了2种适用于脱硫废水膜浓缩浓水的DSA阳极材料的电解制氯性能,并考察了电流密度、温度、极板清洗等因素对电解制氯的影响。结果表明:Keramox涂层(不抗氟)电极的制氯性能明显优于MS-0880涂层(抗氟)电极;Keramox涂层电极电解的最佳电流密度为100mA/cm2,最佳温度为20℃,相应的电流效率可达62.6%,直流电耗为4.59(kW·h)/kg;通过定期酸洗可有效恢复电极性能;2种电极的强化寿命均超过30h,满足工业应用要求;在试验工况下,电解制氯过程符合零级动力学方程。
[Abstract]:Aiming at the characteristics of high COD concentration and a small amount of F- in desulfurization wastewater of a power plant, the electrolytic chlorine production properties of two kinds of DSA anode materials suitable for concentrated water concentration in desulfurization wastewater were studied by using standard three-electrode electrochemical system. The effects of current density, temperature and plate cleaning on electrolysis chlorine production were investigated. The results show that the chlorine preparation performance of the 1: Keramox coated electrode is obviously better than that of the MS-0880 coating electrode. The optimum current density is 100 Ma / cm 2 and the optimum temperature is 20 鈩，
