摘要
蚯蚓生物堆肥作为一种新型的堆肥方式为规模化奶牛养殖场粪污处理提供了新的途径。我国已出台多项相关政策,为奶牛粪蚯蚓生物堆肥技术发展推广提供了良好条件。奶牛粪经蚯蚓过腹处理得到的蚯蚓粪和蚯蚓均具有较好的利用前景。本文以1000头规模化奶牛养殖场为例,设计了该技术模式的一般工艺流程,并对该模式下的经济效益、环境和社会效益进行了分析,以期为奶牛粪蚯蚓生物堆肥技术模式推广提供依据。
As a new type of composting method,earthworm biological composting shows great development potential,provides a new way for large-scale dairy farms to treat cow manure.The government has issued a number of relevant policies,which provide good conditions for the development and promotion of dairy cow dung earthworm biological composting technology.The worm feces and earthworms obtained by the treatment of cow dung through the abdomen of earthworms all have good prospects for utilization.This paper takes a 1000-head dairy farm as an example to design the general process flow of this technology model and the economics of this model.Benefits,environmental and social benefits were analyzed,in order to provide a basis for the promotion of the technology model of dairy cow manure and earthworm biological composting.
