电化学氧化法处理低浓度氨氮废水的研究
Study of advanced treatment in low ammonia nitrogen water by electrochemical oxidation process
摘要
Abstract
In this study ,the electrochemical oxidation was used in the treatment of low con-centration ammonia nitrogen wastewater and its influence factors on the ammonia-nitrogen removal efficiency ,such as the current density ,the chloride ion concentration ,the initial pH and the ammonia concentration were studied .The results showed that :ammonia can be com-pletely removed in 50 min and the concentration of ammonia has little effect when the initial ammonia concentration was 300 mg/L ,the current density was 20 mA/cm2 ,the chlorine ion concentration was 5 000 mg/L ,the initial pH was controlled in the range of 7~9 .The elec-trochemical oxidation was used in the treatment of the practical wastewater at the optimum process parameters ,ammonia nitrogen could be removed completely after 60 min ,while the TOC removal rate was 30% and the energy consumption for wastewater treatment was 18 KW .h/t .关键词
