摘　　要：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 statistic of international economy organizations,the civil economy damage is about 20～60 times than the energy itself because of energy shortage.Recently,due to the limitation of purifying dung and urine,the method of using dung or urine as compost to solve energy shortage have been attached much importance.By comparison with the purification of dung and urine,the disposal cost of the compost technology is low and can renew wasted resource.Therefore,it is an advisable measure.Dung,as a raw material of compost,has a tigher value than other country byproduct,urban and industrial waste.So,there are wide application perspectives in the field of waste energy utilization.However,there exist some problems during the process of application because of the circulation of unbaked compost,relatively higher price of organic matter and byproduct fertilizer.This paper introduces the purpose,characteristic and application of dung compost and analyzes the main problem duing the process of dung and urine compost.
