摘　　要：以西宁地区牛羊屠宰厂废弃物为研究对象,以减少环境污染、综合利用为目标,分析检测了西宁地区牛羊屠宰厂废弃物的组成,并进行了自然发酵和添加酵素菌发酵的对比试验。试验结果:西宁地区牛羊屠宰厂废弃物中含N0.83%、P2O50.23%、K2O0.67%、有机质52.18%、有机物总量69.59%、水分52.66%、粗灰分30.41%。结果表明:西宁地区牛羊屠宰厂废弃物中营养元素多、有机质含量高,添加酵素菌可以缩短发酵时间,减少养分损失。In the trial, wastes from the cattle and sheep＇s butchery in Xining region was selected as research material and investigated to reduce environmental pollution and take comprehensive utilization. The composition of wastes were analyzed, and the comparative test between natural fermentation and enzyme microorganism fermentation was made. The results showed that there were 0.83 % N, 0.23 % P205, 0.67 % K2O, 52.18 % organic matter, total amount of organic 69.59 %, 52.66 % moisture, 30.41% ash in wastes. The conclusion can be made that there were multi-nutrient elements and high organic matter content in wastes, the fermentation time can be shortened by enzyme microorganism fermentation.
