摘要
农业废弃物蕴涵着巨大的能量,德宏州农业废弃物太阳能值达9.217×10^(22)sej。不当的处理方式会造成能量损失,还可能产生污染空气、水体、土壤的污染物,要稀释这些污染物,大气、水体污染降级所需环境贡献能值分别为1.76×10^(15)sej和1.74×10^(22)sej。德宏州原有的处理方式废弃物利用率仅为1.338×10~4sej/J,而使用(饲料+有机肥)废弃物循环处理法,废弃物资源利用率达到了2.54×10~6sej/J,具有较好的资源效益和环境效益。
The agricultural wastesinDehong contain 9.217×10 22 sejofliuge energy. Inappropriate disposal of the wastes would lose energy and pollute air, water, and soil. In order to consume these wastes, 1. 76×1015sej and 1. 74×10 22sej of energy were needed to degrade air and water pollution. The utilization rate of the previous ways of disposing the waste was just 1. 338×104sej/J. However, the utilization rate would reach to 2. 54 ×10 6sej/J when the recycling process of forage and organic fertilizer was applied, which indicated a better resource benefits and en-vironmental benefits.
