摘要
湿式空气氧化法(WAO)和超临界水氧化法(SCWO)废水处理技术近年已有广泛研究。当催化剂存在于氧化体系时,不仅能降低反应温度、压力,而且可提高废水中有害物质的降解效率。介绍了氨的湿式空气氧化和超临界水氧化催化剂应用的研究进展、各种催化剂在超临界水中的稳定性能及氨的催化超临界水氧化情况。
Wet air oxidation (WAO) and supercritical water oxidation (SCWO) as innovative wastewater treatment technologies have received considerable research attention in recent years. The addition of catalysts into oxidation system can decrease the reaction time, lower the reaction temperature and increase the degradation rate of pollutants in wastewater. The research progresses of catalysts used in the treatment of ammonia wastewater by WAO and SCWO are reviewed, and the stability of different catalysts and the oxidation of ammonia in supercritical water are described.
