  • 摘要: 为研究电化学技术对海水养殖尾水中氨氮和亚硝酸盐的去除作用,以天津市杨家泊镇某海水养殖工厂排放的养殖尾水为研究对象,选用DSA(dimensionally stable anodes)电极、间歇流的处理方式,考察电压、电极板间距、电化学处理时间对养殖尾水中氨氮和亚硝酸盐去除率的影响,并进行了能耗分析。结果表明:在电极板间距为2 cm,电压为3 V、电化学处理时间为5 min时,氨氮去除率达96.0%,此时能耗仅为0.79 kW·h/g;电极板间距为3 cm,电压为3 V,电化学处理时间为7 min时,亚硝酸盐去除率最高,为98.9%;去除亚硝酸盐的最低能耗为0.032 kW·h/g,此时去除率为75.2%;27组试验组中有14组经电化学处理后的养殖尾水总无机氮浓度达到SC/T 9103—2007《海水养殖水排放要求》一级排放标准。电化学技术对氨氮和亚硝酸盐均有很好的去除作用,不同试验条件下氨氮和亚硝酸盐去除率均较高,且能耗较低。
