基于某南方填埋场筛分资源化车间氨气浓度分布的喷淋除臭工艺优化方向葛亚军,杨旭,曹占强,戴小东(北京首创环境科技有限公司,北京101300)【摘要】以某运行中的生活垃圾填埋场筛分资源化项目为研究对象,通过检测车间中不同区域的氨气浓度,取得以氨气为代表的车间臭气分布结果。结果表明:筛分车间上料区、滚筒筛设备区和腐殖土落料区为重点除臭区域。设计除臭系统时,应在这些区域增加除臭液喷淋量和喷淋频率。除臭效果持续时间的检测结果表明,停止喷洒除臭剂后,臭气浓度缓慢回升,但7min后,回升速度加快。因此,卸料间隔小于8min时,才能获得较为持续的除臭效果。相关结果可为同类项目除臭系统设计局部细化提供参考。【关键词】筛分资源化;填埋场;除臭;植物除臭剂中图分类号:X701文献标识码:A文章编号:1005-8206(2023)01-0087-04DOI:10.19841/j.cnki.hjwsgc.2023.01.014OptimizationofSprayDeodorizationProcessBasedonAmmoniaConcentrationDistributionofScreeningandRecyclingWorkshopinASouthernLandfillGEYajun,YANGXu,CAOZhanqiang,DAIXiaodong(BeijingCapitalEnvironmentalTechnologyCo.Ltd.,Beijing101300)【Abstract】Ascreeningandrecyclingprojectofawastelandfillinoperationwastakenastheresearchobject,bydetectingtheconcentrationofammoniagasindifferentareasoftheworkshop,thedistributionresultsoftheworkshopodorrepresentedbyammoniagaswereobtained.Theresultsshowedthatthefeedingarea,trommelscreenequipmentareaandhumusblankingareaofthescreeningworkshopwerethekeydeodorizingareas.Whendesigningthedeodorizingsystem,thesprayingvolumeandfrequencyofdeodorizingliquidshouldbeincreasedintheseareas.Thedetectionresultsofthedurationofthedeodorizingeffectshowedthatafterthedeodorantsprayingwasstopped,theodorconcentrationslowlyrecovered,butaftersevenminutes,therecoveryspeedaccelerated.Therefore,whenthedischargeintervalwaslessthaneightminutes,amoresustainabledeodorizationeffectcouldbeobtained.Therelevantresultscouldprovidereferencesfortherefinementofdeodorizationsystemdesignofsimilarprojects.【Keywords】screeningandrecycling;landfill;deodorization;plantdeodorant1引言生活垃圾筛分资源化工艺是填埋场治理技术中的一种。与原位治理技术相比...
