摘要
对上海市区3个不同位置的垃圾中转站运行过程中的臭气产生状况进行了为期一年的监测和分析,研究了其浓度和变化规律。结果表明,3个中转站内气体污染物中H2S、NH3以及臭气浓度范围分别为0.005～0.20mg/m3,0.44～4.67 mg/m3以及16～40,大多在春季达到最高,且与温度和垃圾量没有明显相关性。而挥发性有机物VOCs中主要有1,2-二氯乙烷、苯、甲苯、乙酸乙酯、间二甲苯等污染物,浓度在10-1～103μg/m3之间变化。分析结果表明,臭气浓度和VOCs的产生量与日垃圾处理量呈正比。
The odor generated by three different transfer stations（TSs） in Shanghai was monitored and assayed for a year.The results showed that odor pollutants,such as H2S,NH3 and their odor concentration,in these three transfer stations（TSs） ranged from 0.005 to 0.20 mg/m3,0.44 to 4.67 mg/m3 and 16 to 40 respectively,and most of them were higher in spring,showing no obvious linear correlation with temperature and waste amount.The concentrations of main VOCs pollutants,such as 1,2-dichloroethane,benzene,toluene,ethyl acetate and meta-xylene,were within 10-1~103 μ g/m3.The comprehensive evaluation of the result showed that the odor concentration and the VOCs amount were proportional to the amount of daily waste treatment capacity.
