生活垃圾转运站臭气属性特征及不同除臭工艺效果分析

Analysis on Characteristics of Stench and Effect of Different Deodorization Processes in Domestic Refuse Transfer Station

通过对北京市2座垃圾转运站内外不同除臭工艺的开启前后臭气的定性及部分恶臭指标(臭气浓度及氨)的定量分析,结果表明:2个转运站在除臭系统开启前分别检出挥发性有机物31种和28种,其中转运站不同区域(转运站内和门外5 m处)均检出挥发性有机物分别为22种和21种,系统开启后分别检出挥发性有机物29种和22种,其中转运站不同区域(转运站内和门外5 m处)均检出挥发性有机物分别为20种和18种,2个转运站在除臭系统开启前后,不同区域共检出6种美国环保署(USEPA)优先控制污染物。

The quantitative analysis of some odor targets（odor concentration and ammonia）and qualitative analysis of the odor from two kinds of refuse transfer stations inside and outside in Beijing with the opening before and after different deodorization process were carried out. Before the opening of deodorization process,31 kinds and 28 kinds of volatile organic compounds（VOCs）were detected respectively. 22 kinds and 21 kinds of VOCs were separately detected in different areas of transfer station（inside and 5 meters outside the transfer station）among them. Identically,after the opening of the system,29 kinds and 22 kinds of VOCs were detected respectively,with 20 kinds and 18 kinds of VOCs were separately detected in different areas of transfer station among them. Before and after the opening of the deodorization system,six USPEA priority pollutants were detected totally.
