  • 摘要: 开发了一种新型淹没式平板膜组件,可将废水中氨氮进行富集分离。在实验室条件下,探讨了电极材料、电流强度、电极淹没比、膜出水流量、出水抽停比对膜组件氨氮富集效率的影响。结果表明:铁电极稳定时氨氮富集率为66.88%优于钛电极时的60.33%;在考察的电流范围内,氨氮富集率与电流呈正相关,膜出水流量为2.9 mL·min-1时氨氮富集率达到最佳为81.7%;电极淹没比与氨氮富集率呈负相关;膜运行最佳出水抽停比为10 min:5 min,此时富集率达到稳定。
    Abstract: A novel composite membrane that can separate and enrich NH4+ from wastewater was developed.The influence of factors that enrich NH4+(under laboratory conditions) were studied,such as electrode materials,current intensity,electrode submerged ratio,effluent flow of the membrane,and on/off pump ratio.The results indicated a 66.88% NH4+ enriching efficiency with the iron electrode,which was higher than that of the titanium electrode(60.33%).While a positive correlation was observed between the current intensity and the NH4+ enriching efficiency,a negative correlation was observed between the current intensity and electrode submerged ratio.An optimal NH4+ enriching efficiency of 81.7% was observed when the effluent flow of the membrane was 2.9 mL·min-1.Furthermore,an on/off pump ratio of 10 min:5 min yielded a stable NH4+ enriching efficiency.
