摘要
2-萘酚是严重污染环境和危害人体健康的有害物质,目前采用传统废水处理方法,很难将其彻底去除。超临界水氧化技术是一种新兴废水处理技术,能够对许多传统方法难以去除的有机废水进行有效处理。对含2-萘酚废水的超临界水氧化降解进行了研究,主要讨论了温度、压力、停留时间等因素对反应的影响,2-萘酚的降解率随着这3个因素的升高而升高;同时比较了Cu2+与Mn2+对2-萘酚降解的作用,得出Cu2+具有更好的催化效率;在此基础上确定了本实验体系适宜的工艺条件。
2-naphthol,as a harmful pollutant,has seriously affected on human health.It is difficult to completely decompose 2-naphthol by traditional wastewater treatments.Supercritical water oxidation(SCWO) is the promising technology for the treatment of organic-contained wastewater.The supercritical water oxidation of 2-naphthol was investigated,and the effects of temperature,pressure and residence time on the decomposition of 2-naphthol were investigated,the results show that the removal rate of 2-naphthol was increased with the raising of the three factors.Degradation of Cu2+ and Mn2+ on the 2-naphthol was compared,and Cu2+ had a better catalytic efficiency.Under these conditions,appropriate conditions in this experimental system were determined.
