据国际经济界分析统计 ,由于能源不足引起的国民经济损失大约为能源本身价值的 2 0～ 60倍。最近 ,由于家畜粪尿的净化处理有一定的局限 ,用家畜粪尿制成堆肥或液肥以实现粪尿的资源化成为各方面关注的问题。与对家畜粪尿的净化处理相比 ,不仅处理费用低且可以再利用废弃的资源 ,因而是一种可取的处理手段。畜粪作为堆肥的原料价值优于其它农副产品、都市及工业废弃物 ,在废物能源化领域中有着广泛的应用前景。但由于未熟堆肥的流通、有机质和副产品肥料价格较高等原因 ,在应用的过程中存在一些问题。文章介绍了畜粪堆肥的目的、特点及其应用 ,并分析了当前家畜粪尿堆肥化过程中出现的主要问题。
According to the statistics of the international economic community, the national economic loss caused by insufficient energy is about 20 to 60 times of the value of energy itself. Recently, as livestock decontamination has some limitations, the compost or liquid fertilizer made from livestock excreta in order to realize the reutilization of excrement becomes a concern in various aspects. Compared with the decontamination of livestock excrement, it is not only a cheap treatment but also the reuse of waste resources, so it is a desirable treatment. The value of animal manure as a raw material for compost is superior to other agricultural and sideline products, urban and industrial wastes and has broad application prospects in the field of waste energy. However, due to the circulation of immature compost, organic fertilizer and by-product fertilizer prices higher reasons, there are some problems in the application process. This paper introduces the purpose, characteristics and application of manure composting, and analyzes the main problems in the composting process of manure excrement.
