办沼气将引起农村燃料、肥料、环境卫生的一埸技术革命,而其实际效盆如何,需要首先予以明确。我们从北京郊区情况出发,着重对燃料、肥料效益作了一些试验和调查研究,其中许多工作是和顺义县沼办、荣各庄大队一同进行的,现将结果整理报告如下。一、办沼气的燃料效益露天堆肥是我国北方农村几千年来的积肥方式,达种方式主要是好气性微生物分解有机物,分解过程有相当部分的化学能转化为热能,表现为堆肥温度升高,热能在空气中散失;
Doing biogas will cause a revolution in rural fuel, fertilizers and sanitation, and its actual effectiveness needs to be clarified first. Based on the situation in the suburbs of Beijing, we made some experiments and investigations on the benefits of fuels and fertilizers. Much of our work has been carried out with the Shunyi County Marshes Office and Ronggezhuang Brigade. The results are summarized as follows. First, the fuel benefits of running biogas Open-air compost is the rural areas in northern China for thousands of years of fertilizer, up to species mainly aerobic microbial decomposition of organic matter, a considerable part of the decomposition process of chemical energy into heat energy, manifested as compost temperature , Heat loss in the air;
