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7 min后,回升速度加快。因此,卸料间隔小于8 min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。
A screening and recycling project of a waste landfill in operation was taken as the research object,by detecting the concentration of ammonia gas in different areas of the workshop,the distribution results of the workshop odor represented by ammonia gas were obtained.The results showed that the feeding area,trommel screen equipment area and humus blanking area of the screening workshop were the key deodorizing areas.When designing the deodorizing system,the spraying volume and frequency of deodorizing liquid should be increased in these areas.The detection results of the duration of the deodorizing effect showed that after the deodorant spraying was stopped,the odor concentration slowly recovered,but after seven minutes,the recovery speed accelerated.Therefore,when the discharge interval was less than eight minutes,a more sustainable deodorization effect could be obtained.The relevant results could provide references for the refinement of deodorization system design of similar projects.
