Description
Technical field
The present invention relates to a kind of agricultural byproducts circulating resources and utilize the new technology of sustainable production biogas, belong to agricultural and sideline product
Product technical field of comprehensive utilization.
Background technology
Along with socioeconomic development and structural readjustment of rural industry optimization, livestock breeding industry is fast-developing, scale, collection
Reduction livestock and poultry cultivation scale constantly expands, and progressively instead of the decentralized cultivation of traditional type, it has also become the certainty of animal husbandry development
Trend.In recent years, China's poultry industry development is swift and violent, and livestock and poultry cultivation had become the important channel of growth of agricultural efficiency, increasing peasant income already.But
Along with the development of animal husbandry, a large amount of feces of livestock and poultry to environment cause pollution, feces of livestock and poultry and sewage with to the pollution of environment and
The impact bringing himself sustainable development, it has also become the principal element that restricting current animal husbandry develops in a healthy way, also to livestock products
The safety of product constitutes a threat to, pollution administration, protects and improves the ecological environment, and promotes livestock and poultry breeding industry sustainable development, it has also become
The task of top priority of new century agricultural environmental protection.On the premise of not with sacrificialing environment quality as cost, it is achieved livestock and poultry cultivation quick
Increase, change traditional production of energy mode and consumption pattern, utilize livestock and poultry liquid dung to develop biomass and produce the energy of cleaning
Source is one of best selection.Utilize anaerobic digestion techniques to process livestock breeding wastewater, produce clean energy resource biogas, administering
Turn waste into wealth while pollution, reduce the discharge capacity of greenhouse gases, thus realize the sustainable development of national economy.
Agricultural crop straw is the first big reproducible living resources in the world, is also a kind of important money that can comprehensively utilize
Source.How making full use of stalk resource and not making environment be contaminated is a great problem that faces of modern agriculture.Straw profit at present
During with, most with fertilizer (including direct returning to farmland) utilization, account for the 36.6% of stalk resource, next to that direct fuel and raising
Material consumption, accounts for the 23.7% and 22.6% of stalk resource respectively, and other is as the raw material of industry (papermaking etc.), burned and throw aside and account for altogether
