摘要:研究了甘蔗榨季和非榨季期间蔗渣堆场空气中挥发性有机物的种类和含量的变化，并对蔗渣堆场渗滤液的有机物种类进行了分析。结果表明，在榨季和非榨季堆场空气中可分别检出32种和24种有机污染物；榨季堆场空气中挥发性有机污染物的浓度比非榨季高。在蔗渣堆场渗滤液中共检出32种有机污染物，其中酸类和芳烃类化合物各占14种。

Abstract:Ambient VOCs samples and bagasse infiltration fluid at bagasse yard in a paper mill during the periods of pressing and non-pressing season of sugarcane were analyzed. Results showed that 32 and 24 kinds of compounds were detected in the pressing and non-pressing seasons,respectively; Compared to the non-pressing season, concentrations of most of the volatile organic pollutants were higher in the pressing season. There were 32 kinds of volatile organic pollutants that were detected in bagasse infiltration fluid, among which 14 kinds were acids and 14 kinds were aromatic hydrocarbon compounds. Therefore, the environmental management should not be overlooked in bagasse yard of paper mill.
