生活垃圾转运站恶臭污染指标初探

Elementary Study of Odor Contaminations in Municipal Solid Waste Transfer Station

报道了广州部分垃圾转运站恶臭指标的检测结果。发现国家标准(GB14554-1993)中的单项污染物指标的测定值大多远低于标准限值,而综合指标臭气浓度普遍超标,两类指标间存在严重不符。利用SAS统计软件综合分析各指标的检测数据,结果表明,垃圾转运站臭气中恶臭指标的含量存在较大的变异,且在垃圾站内的变异程度更大;恶臭单项指标在垃圾站内和垃圾站边界点的测定均值间无显著差异;臭气浓度和恶臭单项指标整体间可能存在一定的线性关系,但和某个具体的恶臭指标的线性相关性并不显著。

This paper reports the determination results of odor targets in Municipal Solid Waste Transfer Station （SWTS） based on national standard （GB14554- 1993）, which provides a proof about the inconsistency between odor concentration and other odor targets, Analyzing the data using SAS software, more characteristics of odor targets in SWTS are discovered ： First, odor targets have broad range deviation, and in the SWTS, the deviation is more; Second, except odor concentration, there have no significant difference at the 0.05 level while comparing the mean of odor targets in and out SWTS ; And the third, although odor concentration and other odor targets have theoretically lineal correlation, the correlation between odor concentration and the certain odor target has not be found.
