Process and production line for harmless treatment of livestock and poultry breeding and slaughtering wastes and agricultural wastes

Abstract

The invention relates to a production line for harmless treatment of livestock and poultry breeding and slaughtering wastes and agricultural wastes, belonging to the fields of animal husbandry and harmless treatment of the agricultural wastes, and aiming at solving the problem of resource regeneration and utilization of the animal husbandry and the agricultural wastes. The carcasses of sick animals or the slaughtering wastes are crushed and cured, the separated water granulated slag and the crushed agricultural wastes are mixed with the recovered biogas slurry, and the obtained mixture is sentto an anaerobic fermentation tank so as to be subjected to anaerobic fermentation. The separated crude oil is purified to generate biodiesel or chemical oil, and the biogas produced by means of fermentation is purified for being used as fuel for calcining ceramsite or purified into natural gas. The biogas residue obtained after the anaerobic fermentation is mixed with the construction spoil or river silt so as to be granulated, the obtained granules are sent to a ceramsite calcining device so as to be calcined into light ceramsite, and the product can be made into a wallboard together with cement, gypsum and the like. The biogas slurry is returned to the production process or used for preparing fabricated wall panels. The production line realizes energy utilization and building material utilization during waste treatment, enables the environmental, social and economic benefits to be coordinate and unified, and is suitable for the treatment and comprehensive utilization of livestock and poultry farming and the agricultural wastes.

Description

Technical field [0001] The present invention belongs to the field of harmless comprehensive treatment of animal disease and death carcasses, livestock and poultry slaughter waste and agricultural waste in the livestock industry, and mainly relates to the prevention of disease and death of livestock and poultry, slaughter waste and agricultural waste in the process of treatment.
