| 摘要： | Landfill site is one of important odour emission sources.Odour emissions from landfill sites depend on the waste buried,operation activities,running conditions,etc.Odorants from landfill sites may include reduced volatile organic sulfur compounds (VOSCs),volatile organic compounds (VOCs),inorganic compounds,and so on.A set of sampling and measurement methods had been used for determination of odorous compounds from a municipal waste landfill site.Emissions from landfill gas and leachate were all considered and measured for identification of potential odorant contributors.Landfill gas was sampled directly into Tedlar bags for sulfur compound analysis,while Tenax TA sorbent tube samples were collected for VOC determination.5 L of leachate sample was also collected from the leachate storage dam for flux hood emission test as emission sampling was impossible to be conducted on-site because of safety issue.14 volatile sulfur compounds were identified in the landfill gas,of which 10 were quantified with the concentrations of 5 VOSCs above their odour thresholds and identified as potential contributors to the odour observed on site.The VOSC speciation of the leachate flux hood emission samples identified only two major sulfur components: carbonyl sulfide (COS) and hydrogen sulfide (H2S); and their abundances are considerably less (H2S = 0.0006 mg/m3) than that from the landfill gas (H2S = 0.0257 mg/m3).Over 130 VOCs were detected in the landfill gas; with at least 28 of them being documented odorants.However only 6 VOCs were identified as odorant contributors in the leachate emission samples. |
