采用CuO-ZnO/多孔陶瓷为粒子电极的三维电催化氧化技术，对氨氮与2-氨基吡啶模拟废水的电催化氧化降解中的竞争过程进行研究。考察了氨氮及氨氮与2-氨基吡啶直接氧化和间接氧化降解的情况，并分析了氨氮与2-氨基吡啶的竞争反应过程。结果表明：间接氧化过程更有利于氨氮的去除，并可降低硝酸盐氮的累积率，2-氨基吡啶主要通过直接氧化降解，不受氨氮和氯离子的影响，直接氧化条件下2-氨基吡啶开环产物与氨氮存在强烈的竞争现象，间接氧化对2-氨基吡啶开环产物与氨氮的降解都有提高，且氨氮的去除优先于2-氨基吡啶开环产物。因此，可以通过改变三维电催化体系的直接和间接氧化条件，调整氨氮与有机物的去除效果，并可应用于含氨氮有机废水处理的现场调试。

Competition between ammonia and 2-aminopyridine was studied by three-dimensional electrocatalytic with CuO-ZnO/porous ceramic as particle electrodes. The direct and indirect electro-oxidation degradation of ammonia,ammonia and 2-aminopyridine was investigated,and competition between ammonia and 2-aminopyridine was analyzed. Indirect oxidation process was more conducive to removing ammonia , and could reduce accumulation rate of nitrate nitrogen , while 2-aminopyridine was degraded mainly through direct oxidation and was not affected by ammonia and chloride ions. Ammonia and intermediates of 2-aminopyridine showed strong competition under direct electro-oxidation. Degradation of ammonia and intermediates of 2-aminopyridine increased under indirect electro-oxidation,and ammonia was preferably removed than 2-aminopyridine intermediates. Changing the conditions for direct and indirect electro-oxidation of the three-dimensional system could adjust removal of ammonia and organic matter,and could be used in commissioning wastewater treatment facility.
