| 中文摘要: |
| 针对黄土高原地区自然生态及农村校园环境现状,对“猪、厕—沼—菜”农村沼气生态校园模式系统结构与功能进行了研究和设计,得到卫生厕所亚系统、高效沼气亚系统、生态养殖亚系统及生态种植亚系统(太阳能日光温室)的设计方法和关键技术,并从技术经济方面分析评价了以沼气为纽带的“猪、厕—沼—菜”农村沼气生态校园模式的可行性。该模式的关键技术将微生物(沼气)、动物(猪)、植物(蔬菜)、厕所废弃物(粪污)紧密地结合起来,变废为宝,建立资源节约型、环境高效型生态校园物质能量良性循环体系,具有“四节三增二净化”的综合效应。 |
| 英文摘要: |
| Based on ecology, economics and energy science, a new mode of eco-campus with biogas as a link in the Loess Plateau region of China was presented.The results show that the biogas technology, sanitary toilet, eco-plantation with eco-breeding, the utilization technology of substituting the ferment residues (i.e.bio dross and bio liquid) for pesticide and chemical fertilizer, etc.are feasible in the extreme.Simultaneously, the biogas technology can be used to organize invidual agricultural technology (i.e.pig raising, vegetable planting etc.) properly to produce pollution-free vegetables.In the mode the biogas plays the role as linkage between planting and raising, linking the planting and raising together and improving each other, and forming a benign ecology cycle which can provide social and economic benefits. |
