大型鸡场处理鸡粪的费用昂贵。对许多大型鸡场来说,处理鸡粪而不造成环境污染是一个重要问题,因此,发展利用、处理鸡粪的技术就很有必要。一般来说,一个典型的5万只鸡的蛋鸡场,每天约产生粪肥10吨,这些废物必须进行处理。本文介绍的是利用纯蛋鸡粪肥,通过厌氧发酵,对其生产甲烷潜力进行研究的情况。试验研究所用的鲜粪是当天从喂食玉米和大豆的蛋鸡圈中收集的,通过抽样化验,鲜粪含有80%水分和20%干物质。干物质成分如表1所示。干物质含有76%挥发性固体,亦称 Large farms handling chicken manure is expensive. For many large-scale farms, dealing with manure without causing environmental pollution is an important issue. Therefore, it is necessary to develop and utilize chicken manure. In general, a typical chicken farm of 50,000 chickens produces about 10 tons of manure per day and these wastes must be disposed of. This article describes the use of pure chicken manure, through anaerobic fermentation, the methane production potential of its research. The fresh manure used in the pilot study was collected on the same day from the layers of hens fed with corn and soybeans. Through sampling, fresh manure contained 80% moisture and 20% dry matter. The dry matter components are shown in Table 1. Dry matter contains 76% volatile solids, also known as
