【摘要】 随着水产养殖量逐年增加,养殖废水的污染问题日趋严重,尤其是氨氮,亚硝态氮及有机物等对环境造成了巨大的危害。电化学降解技术一种无二次污染的"环境友好技术",降解过程中,废水中氨氮、亚硝酸盐氮、硝酸盐氮和有机物以氮氧化物,氮气或者二氧化碳的形式从废水中有效去除。电极是影响去除率的一个重要因素,但目前多为贵金属或者其氧化物,经济成本高,所以电化学降解技术在水产养殖废水的应用还处以理论研究阶段。另外,将电化学和其他技术联合的绿色高效的工艺也是电化学在降解水产养殖废水处理中的一个重要研究方向。更多还原

【Abstract】 With the increase of the aquaculture quantity year by year, water pollution problem is getting more and more serious, and ammonia, nitrite and organic compounds have caused tremendous harm to environment. Electrochemical degradation technique is an "environmental-friendly technology" without secondary pollution and has a good application in the treatment of aquaculture wastewater. Ammonia, nitrite, nitrate and the organics are electrochemically degraded to nitrogen oxides, N2, and CO2. Electrode is an important factor to influence the efficiency of electrochemical degradation, but most electrodes are made by noble metal or their oxides with high economic costs, so the application of electrochemical in aquaculture wastewater treatment is still at the theoretical and experimental research stage. Thus, the hot research spot in this field is to prepare inexpensive and efficient electrode. Furthermore, it’s also very important to develop a process of combining electrochemical and other degradation technologies.更多还原
