Abstract

The invention belongs to the technical field of co-production of biogas and organic fertilizer from biomass energy, and particularly relates to a system for co-producing biogas and organic fertilizer from straw, livestock and poultry manure. The system comprises crushing equipment, a biogas slurry temporary storage tank, a pusher, a manure liquid receiving tank, a homogenizing tank, a fermentation tank, a biogas filtering and purifying system and an organic fertilizer treatment system; according to the straw, livestock and poultry manure, biogas and organic fertilizer co-production system, livestock and poultry manure and straw are fermented to produce biogas, high-quality organic fertilizer can be produced at the same time, a proper amount of organic fertilizer is applied at proper time according to different needs of crops in different periods, the application amount of chemical fertilizer can be effectively reduced, and the soil structure is improved; therefore, soil degradation is restrained, groundwater pollution is prevented, and the yield and quality of agricultural products are improved. The system has very important significance for enhancing agricultural ecological environment construction and promoting agricultural sustainable development.

Description

technical field [0001] The invention belongs to the technical field of biomass energy combined production of biogas and organic fertilizer, and in particular relates to a system for combined production of biogas and organic fertilizer with straw, livestock and poultry manure. Background technique [0002] Implementing the strategy of sustainable development is the basic national policy of our country. Sustainable development requires that while economic development is underway, environmental pollution should be controlled and environmental quality improved. At present, the rapid development of my country's large-scale breeding industry is at the expense of the environment to a certain extent. With the rapid development of my country's livestock and poultry breeding industry, the pollution of livestock and poultry manure to the environment has become increasingly prominent. By the end of 2009, the discharge of livestock and poultry manure in China exceeded 4 billion tons, abo...
