能源化工EnergyChemicalIndustry第44卷第3期2023年6月Vol.44No.3Jun.,2023基于AspenPlus的氨氮废水处理流程模拟于国栋，胡德栋*，韩俊杰(青岛科技大学机电工程学院，山东青岛266061)摘要：超临界水氧化技术作为高级氧化技术对氨氮废水具有较好的处理效果，但超临界水氧化技术能耗较大，因此精确预测超临界水氧化工艺参数，进而较好地实现自热可以降低超临界水氧化技术的能耗。采用AspenPlus软件对超临界水氧化工艺进行模拟，研究结果表明，在氧气过量、温度为600℃、压力为25MPa、停留时间为200s时，氨氮废水可以被彻底降解，在1s内大部分有机物被降解，提高反应器和泵的㶲效率能大幅提高超临界水氧化技术的处理能力。关键词：超临界水氧化；AspenPlus；氨氮废水；㶲效率中图分类号：X703；TQ018文献标志码：A文章编号：2095-9834(2023)03-0060-05引文格式：于国栋,胡德栋,韩俊杰.基于AspenPlus的氨氮废水处理流程模拟[J].能源化工,2023,44(3):60-64.SimulationofammonianitrogenwastewatertreatmentprocessbasedonAspenPlusYUGuodong,HUDedong,HANJunjie(CollegeofElectromechanicalEngineering,QingdaoUniversityofScienceandTechnology,Qingdao266061,Shandong,China)Abstract:Asanadvancedoxidationtechnology,supercriticalwateroxidationtechnologyhasgoodtreatmenteffectsonwastewatercontainingammonianitrogen.However,theenergyconsumptionofsupercriticalwateroxidationtechnologyisrelativelyhigh.Therefore,accuratelypredictingtheparametersofsupercriticalwateroxidationprocessandachievingself-heatingcaneffectivelyreducetheenergyconsumptionofsupercriticalwateroxidationtechnology.TheAspenPlussoftwareisusedtosimulatethesupercriticalwateroxidationprocess.Theresearchresultsshowthatunderexcessiveoxygen,temperatureof600℃,pressureof25MPa,andresidencetimeof200s,ammonianitrogenwastewatercanbecompletelydegraded,andmostorganicmattercanbedegradedwithin1s.Improvingtheexergyefficiencyofthereactorandpumpcansignificantlyimprovethetreatmentcapacityofthesupercriticalwateroxidationtechnology.Keywords:supercriticalwateroxidation;AspenPlus;ammonianitrogenwastewater;exergyefficiency收稿日期：2022-07-07。作者简介：于国栋(1997—)，男，山东武城人，硕士研究生在读，研究方向为超临界水氧化技...
