Cooperative treatment method for livestock excrement, organic wastes of processing factory and straws

Abstract

The invention discloses a cooperative treatment method for livestock excrement, organic wastes and sewage of processing factory and straws and belongs to the technical field of environment protectionand renewable energy sources. The cooperative treatment method comprises the following steps: carrying out dry-wet separation pre-treatment on livestock excrement, organic wastes of a slaughter house / a food processing factory, plant straws, waste urine of a livestock farm and wastewater / sewage of the slaughter house; carrying out disinfection and sterilization treatment at high temperature of 70 DEG C and under constant pressure for 30min, and then carrying out high-temperature anaerobic digestion; carrying out desulfurization and purification on biogas in a biogas storage cabinet and conveying the biogas into State Grid and a municipal fuel gas pipe net respectively; conveying dried and qualified biogas residues into related units and preparing the biogas residues into organic fertilizersoil to be subjected to resource utilization; adopting a source pre-treatment technology and carrying out source pre-treatment on the livestock excrement, the organic wastes of the slaughter house / the food processing factory, waste urine of the livestock farm, waste sewage of the slaughter house and the plant straws in a collection vehicle; carrying out drying treatment to obtain a finished product. The squeezed biogas residues enter a solar drying workshop and are further dried; then the biogas residues are convened to the related units to be prepared into the organic fertilizer soil, and the resource utilization is realized.

Description

technical field [0001] The invention relates to the technical field of environmental protection and renewable energy, in particular to a method for synergistic treatment of livestock and poultry manure, organic waste from processing plants and straw. Background technique [0002] Livestock and poultry manure and slaughterhouse / food processing factory organic waste and farm waste sewage and urine water Slaughterhouse waste water and plant straw collaborative treatment method, farm waste water, urine water and slaughterhouse waste water treatment method as aquaculture The waste in the industry has complex components and is extremely perishable and degenerate. It is harmful to the environment and livestock and poultry diseases in the breeding industry, and it is also extremely harmful to the human body. Therefore, livestock and poultry manure and slaughterhouse / food processing factory organic waste and farm waste and urine water slaughterhouse waste water and plant straw collab...
