摘要
对北京市城区和近郊区的新鲜城市生活垃圾进行了分类调查和理化性质测定。结果表明:(1)新鲜生活垃圾可农用部分占84.04%,冬季可农用部分所占比率高;(2)垃圾肥料有机质含量在12.50%—19.70%范围,全氮在0.53%—0.87%范围;(3)垃圾肥料重金属含量和残毒含量符合国家卫生标准和城市垃圾农用控制标准。建议垃圾肥料与处理过的禽畜粪便混合,可生产出优质有机肥料。
In this study, a survey is conducted to have classed municipal garbage in urban and suburb of Beijing and their physical and chemical properties were tested. The results showed that: 1. 84.04% of the fresh municipal garbage was a vailable use on agriculture with the highest amount in winter; 2. The organic ma tter contents in the garbage compost were in a range of 12.50%to 19.70%, while total nitrogen of 0.53%— 0.87%; and 3.
