校园生活垃圾的理化特性及分类研究

Studyon Physicochemical Property and Classification of Campus Solid Waste

对校园生活垃圾物理组成、含水率、热值进行测试和分析。结果表明:校园生活垃圾的主要物理组分有易腐类(24%)、塑料(19%)、草木类(16%)、纸类(13%)、玻璃(8%)、金属(6%)、布类(5%)、橡胶(4%)、土渣(3%)及其它类占2%,含水率均值为40.45%,热值均值为23194.89 kJ/kg。利用聚类分析法进行垃圾处理组分分类分析,根据分类结果探讨了垃圾处理可行性分析,对校园生活垃圾分类及处理方面提供参考。

The physical composition,moisture content and calorific value of campus solid waste were tested and analyzed.The results showed that the main physical components of campussolid waste were perishable(24%),plastic(19%),vegetation(16%),paper(13%),glass(8%),metal(6%),cloth(5%),rubber(4%),soil residue(3%)and other types accounting for 2%.The average moisture content was 40.45%,and the average calorific value was 23194.89kJ/kg.According to the classification results,the feasibility analysis ofcampus solid wastetreatment was discussed,which could provide reference for the classification and treatment of campussolid waste.
