Abstract: A pilot-scale experiment was conducted in order to remove ammonia nitrogen from gold smeltery industrial wastewater, Zijin Mining Group Co.,Ltd., by electro-catalytic-oxidation process. The results showed that: electrolytic time has significant effects on ammonia nitrogen removing rate; batch treatment indexes are better than continuous, and with little costs. Electro-catalytic-oxidation operation has the advantages of low cost, fine effect and operating environment friendly, and considered to have a welcome industrial application prospect.
