徐州市城市生活垃圾重金属污染程度及空间分布

Degree and Spatial Distribution of Heavy Metals Pollution of Municipal Solid Waste in the City of Xuzhou

通过调研和现场取样检测,对徐州市区生活垃圾中的重金属污染程度及空间分布进行了评价。发现徐州市城市生活垃圾中的主要重金属污染元素均属于轻污染,各采样点污染程度依次是火车站>奎园>西苑小区>风华园>戏马台>彭城广场>矿大南湖;重金属元素含量低于城镇垃圾农用控制标准,对城市生活垃圾资源化利用提供了科学依据。

The degree and spatial distribution of heavy metals pollution of municipal solid waste （ MSW ） in Xuzhou were assessed after investigation and sampling on the spot. The degree of the chief heavy metal pollution of municipal solid waste was light. The pollution levels of each sampling point were railway station 〉 Kui Yuan 〉 Xiyuan district 〉 Fenghuayuan 〉 Xima Tai 〉 the square of Peng cheng 〉 the South Lake Campus of China University of Mining and Technology. The heavy metal contents were lower than the Control standards for urban wastes for agricultural use. The results provided the scientific basis for resource utilization of municipal solid waste.
