As a basic means to control odorants released from a landfill leachate treatment station (LLTS), effluents venting from this station were treated via incineration with methane rich landfill gas (at 750°C). A list of the key offensive odorants covering 22 chemicals was measured by collecting those gas samples both before and after the treatment. Upon incineration, the concentration levels of most odorants decreased drastically below threshold levels. The sum of odorant intensities (SOIs), if compared between before and after incineration, decreased from 6.94 (intolerable level) to 3.45 (distinct level). The results indicate that the thermal incineration method can be used as a highly efficient tool to remove most common odorants (e.g., reduced sulfur species), while it is not so for certain volatile species (e.g., carbonyls, fatty acids, etc.).
作为控制垃圾渗滤液处理站(LLTS)释放的污染物的基本手段,通过用富含甲烷的垃圾填埋气(750°C)对该站的排放物进行焚烧来进行处理。通过收集处理前后的气体样本,测量了涵盖 22 种化学物质的关键恶臭污染物清单。在焚烧过程中,大多数污染物的浓度水平急剧下降到阈值以下。如果将焚烧前后的气味强度总和(SOI)进行比较,它从 6.94(无法忍受的水平)下降到 3.45(明显的水平)。结果表明,热焚烧法可作为一种高效去除大多数常见污染物(例如,还原硫物质)的工具,而对于某些挥发性物质(例如,羰基化合物,脂肪酸等)则不是如此。
