| 摘 要： | 分2-3次随机采集北京市城八区的5个垃圾转运站及宣武区、丰台区8个功能区共48个生活垃圾样品，分别测定垃圾的有机质含量、含水率、密度、pH和C／N指标，用Fisher判别法初步评价48个垃圾样品堆肥的适宜性并建立堆肥适宜性的判别函数。用小武基和马家楼转运站筛分后粒径15～60mm的垃圾堆肥适宜性的判别函数进行检验，准确率达100％，8周堆肥的腐熟度指标变化验证了判别函数。通过判别函数推出决定垃圾堆肥的主要因素为垃圾的含水率和C／N。

| Abstract: | Forty-eight domestic waste samples selected from five waste transfer stations in Beijing city and eight functional districts in Xuanwu district and Fengtai district were measured to identify the content of organic matter,moisture content,density,pH and C/N in domestic waste.According to Fisher discriminant analysis,Fisher discrimination function was established to judge the suitability of domestic waste composting.The accuracy rate of Fisher discrimination function on suitability of domestic waste compostin... |
