城镇生活垃圾污染现状调查研究

Investigation of Pollution Status of Municipal Solid Waste

指出了随着城镇化进程的加快和社会消费水平的提高,城市生活垃圾日益成为亟待解决的社会问题,在此基础上提出了城市生活垃圾的改进方案及实施的保障措施。

This article studies the physical and chemical characteristics of the sorting waste（dry and wet waste）in Shanghai based on field sampling and laboratory testing, and monitors the indexes including physical composition, moisture, unit weight, calorific value, elements and biochemical indexes. And then it proposes some relevant treatment measures. The results show that, for dry sorting waste, the organic matter decreases by 30%, while potentially recyclable waste and combustible materials increase about 75%0, moisture and unit weight decrease significantly, and the calorific value （wet low calorific value） is between 6881~7279 kJ/kg, which is suitable for incineration disposal; for wet sorting waste, organic matter is 80%, moisture is 72 % unit weight is 304 kg/m3, calorific value is lower than 2500 kJ/kg, organic matter, protein and fat content are respectively 75% 14% and 7% of dry material proportion, which is proved to be a good material for biochemical comnost.
