【摘要】 利用自制的间歇式超临界水氧化(SCWO)装置对乙醇废水进行实验研究。实验表明:超临界水在低压下对乙醇废水的氧化效果影响很大,高压下影响逐渐变小;随着温度的升高及停留时间的增加,乙醇废水的去除率随之提高;乙醇废水的最终产物为二氧化碳。实验的最佳工艺条件为:压力30MPa、温度600℃及停留时间30s。更多还原

【Abstract】 Ethanol wastewater treated by supercritical water oxidation technique is studied in intermittent experimental equipment. The results show the pressure of supercritical water influences the oxidation degree for ethanol wastewater: the influence decreases with the pressure’s increase. Ethanol removal rate can be improved with increasing the reaction time and the residence time. The best technologic terms as followed: pressure 30MPa、temperature 600℃ and retention time 30s.更多还原
