Abstract

The invention relates to the technical field of livestock dung treatment, and specially, relates to an environmentally friendly recycle method for preparing a civil fuel from fresh cow dung. Herdsmen have habits of preparing a fuel from cow dung from of old. Fresh cattle dung has high water content and thus being dried in air. Fresh cow dung has water content above 80% and thus needing long time for drying in air, and it is the biggest difficult point in timely treatment and recycle of the fresh cow dung. The environmentally friendly recycle method comprises the following steps of mixing uniformly 4.100 to 4.500 parts by weight of fresh cow dung, 4.800 to 4.500 parts by weight of dry coal powder, and 1.100 to 1.000 parts by weight of a mixture of a deodorization adsorbent and a bonding reinforcing mixed agent, compacting the mixture obtained by the previous step by coal product processing equipment for molding, and carrying out a hardening process, wherein a product obtain by the hardening process is utilized as a civil fuel. The environmentally friendly recycle method has simple processes and good practical applicability, can treat fresh cow dung timely and efficiently, can reduce pollution and can improve the environment, and thus compared with the prior art, having real progress.

Description

technical field [0001] The invention relates to the technical field of livestock manure treatment, in particular to an environment-friendly reutilization method for preparing civil fuel from fresh cow manure. Background technique [0002] At present, there are mainly three ways to control and scientifically utilize cow manure, that is, directly as organic fertilizer (feed) material for agricultural production, biogas production or power generation production, edible fungus production substrate and biological fertilizer raw materials, etc. The increase in transportation costs, the large construction costs of biogas and power generation projects and the high operating costs, the particularity of the northern winter climate (very low temperature), and the small scale of edible fungus production have limited the scientific reuse rate to only About 30%, especially in large-scale dairy (beef) cattle breeding plots and pastures with a high degree of intensification, in the late veg...
