摘要
通过构建农业废弃物沼气化利用潜力估算模型,确定各种农业废弃物沼气化转化参数,估算了2009年中国种植业、畜牧业生产和人类生活所产生的农作物秸秆、畜禽粪便和人粪尿等生产和生活废弃物的量,结果表明2009年全国农作物秸秆量达到89 886.75万t、畜禽粪便量达到399 115.6万t,人粪尿达到25 333万t,在35℃条件下沼气化资源潜力为5 832.675亿m3,相当于4.14亿t标准煤。研究种植业、畜牧业等农村生产和生活产生的废弃物数量及其沼气化利用的资源潜力计算方法,对摸清我国农业废弃物数量、沼气化利用潜力具有重要意义。
With the fast development of agricultural economy in China, the quantity of crop straws and other wastes produced by plant industry, animal husbandry and human activities is instantly increased, an estimation of their quantities and associated methods converting to biogas production potential is critical to their rational evaluation and exploration. In this study, conversion coefficients of various agricultural wastes to biogas were determined by development of methods for evaluation of their biogas transforming potentials, and the total amount of agricultural wastes were estimated for the year 2009 in China. The results showed that the amount crop straws reached 8.99 × 10^8 t, excrement and urine of beasts and birds 39.9 × 10^8 t, and the human being＇s night soil 2.53 x l0s t. Their mash gas potentials were estimated to be 5832.67 × 10^8 m3 in total, which is equivalent to 4.14 × 10^8 t SCE （standard coal equivalent）. We conclude that the marsh gas resource potential of agricultural wastes is enormous in China, which is important to practical cycling economy.
