摘    要:采用催化超临界水氧化(CSCWO)技术对香料废水进行氧化处理,研究了催化剂浓度、反应温度、压力、停留时间等因素对废水COD、TN去除效果的影响.结果表明:在超临界水中添加cu2+催化剂后有机物的去除效率与无催化剂时相比有显著的提高.香料废水中COD、TN的去除率随催化剂浓度、反应温度和压力的升高,停留时间的延长而提高....

关 键 词:催化超临界水氧化  均相催化剂  香料废水  影响因素

Abstract:Catalytic Supercritical water oxidation(CSCWO) technology was adopted to treat perfume wastewater.Effects of the catalyst concentration,reaction temperature,reaction pressure and reaction time on degradation efficiency of COD,TN were investigated.The results indicated that in supercritical water,the efficiency of removing organic was much better after adding metal ions such as Cu2 + catalysts.The higher removal rates of COD,TN were obtained at higher concentration of the catalyst,higher temperature,higher pressure and longer residence time.With Cu2 + as the catalyst,under proper reaction conditions(T = 440 ℃,t = 50 s),the removal rate of COD could be over 95%,It showed that catalytic supercritical water oxidation was a high-efficient technology of treating perfume wastewater.
Keywords:CSCWO  homogeneous catalysts  perfume wastewater  influencing factors
