以实际养殖海水中的氨氮为研究对象,采用电化学氧化技术对废水中的氨氮进行去除。分析了氨氮的去除效果,电化学处理过程中产生的残余氯以及三卤甲烷的生成,并考察了电化学技术处理海水中氨氮所需的能耗。结果表明,电化学氧化技术可以有效地将氨氮转化成氮气去除。增加电流密度和水力停留时间可以增加残余氯浓度,但处理实际养殖海水的过程中生成三卤甲烷的量也会增多。另外,电化学技术去除实际养殖海水中的氨氮需要的能耗很低,表明电化学氧化技术可以应用在海水废水的处理。 Ammonia nitrogen in the actual farming seawater as the research object, the use of electrochemical oxidation of ammonia nitrogen in wastewater removal. The removal efficiency of ammonia nitrogen, residual chlorine generated during electrochemical treatment and the formation of trihalomethane were analyzed. The energy consumption of electrochemical treatment of ammonia nitrogen in seawater was also investigated. The results show that electrochemical oxidation technology can effectively convert ammonia nitrogen into nitrogen. Increasing the current density and HRT can increase the residual chlorine concentration but the amount of trihalomethanes formed during the actual aquaculture of the seawater also increases. In addition, the electrochemical energy removal of ammonia nitrogen in the actual farming seawater requires very low energy consumption, indicating that electrochemical oxidation technology can be applied to the treatment of seawater and wastewater.
