摘要
沼气系统是古泉生态实验场的核心部分。通过对沼气的建设和消化池的运转,使实验场产生的有机废弃物得以充分利用,并转化产出了沼气、沼液和沼渣,是农村重要的燃料、饲料和肥料来源。由于废弃物的综合利用,还减轻了实验场各子系统对外界能量的依赖程度,降低了成本,有利于实现持续和稳定的生产,具有显著的经济效益、生态效益和社会效益,故发展沼气是农村生态建设的重要内容之一。
The biogas system is the kernel component of Guquan Experimental Farm of Ecological Engineering. The wastes of the farm are used by the biogas digestors to produce biogas, liquid and solid slurry, which are used respectively as fuel, feed and fertilizer in the farm. Through using integratedly them, the intensity of the farm's being dependent on the input from external system is lightened and the cost of the farm is decreased so that the production of the farm is more sustainable and stalable and that the economic, ecological and social efficiences have been gotten more highly. The authors point out that the development of biogas is one of important projects to rural ecological construction.
