Description
Technical Field
The utility model belongs to the technical field of solid waste handles's environmental protection, concretely relates to dirty and domestic waste integrated processing system of beasts and birds excrement.
Background
China is a big country in livestock and poultry breeding industry. According to the data of the national statistics bureau website, the total value of animal husbandry in 2018 in China is 28697.4 hundred million yuan, and the quantity of stocked pigs, cattle and sheep in the whole country at the end of the year is 42817.11 ten thousand heads, 8915.28 thousand heads and 29713.51 thousand heads respectively. The data of Ministry of agriculture show that the total amount of domestic livestock and poultry manure exceeds 38 hundred million tons, and the manure contains a large amount of organic pollutants, heavy metals, pathogens and the like, which can cause water body pollution, soil pollution, agricultural non-point source pollution, odor pollution, heavy metal pollution and greenhouse effect. If the livestock and poultry manure cannot be effectively treated, the development of animal husbandry is hindered, and the human health and the global ecological environment are greatly damaged. With the continuous enlargement of the livestock and poultry breeding scale, the breeding wastes such as livestock and poultry feces, sewage and the like are rapidly increased, and the livestock and poultry breeding becomes a main source of agricultural pollution in China. In addition, the excrement contains rich organic matters, and huge waste of resources is caused if the organic matters are not utilized.
In addition, domestic waste pollution is also serious in China. The accumulated quantity of the municipal domestic garbage exceeds 70 hundred million tons, the urban domestic garbage occupies about 35 hundred million square meters of land, among 660 cities in the country, 2/3 large and medium cities are surrounded by the garbage, and 1/4 cities are forced to extend a way for solving the garbage crisis to the countryside, so that the secondary pollution of the garbage is caused, and the ecological environment of urban and rural combined areas is rapidly deteriorated. Research indicates that the domestic garbage yield in China will continue to rise and reaches 2.5 hundred million tons in 2025.
In order to solve the problem of environmental pollution caused by solid wastes such as livestock waste, household garbage and the like, the state provides notice of thirteen-five planning about the development of printing energy by the national energy agency of the national development reform committee, and points out that the liquid fuel, the gas fuel and the solid forming fuel of biomass are actively developed to promote the biogas power generation and the biomass gasification power generation. The suggestion of the national academy of affairs office about accelerating the resource utilization of livestock and poultry breeding waste in 2017 indicates that the comprehensive utilization rate of livestock and poultry feces in China reaches over 75% by 2020, the equipment matching rate of feces treatment facilities in large-scale farms reaches over 95%, and the equipment matching rate of feces treatment facilities in large-scale farms reaches 100% one year in advance. In 2017, the country sets the three provinces of Jiangxi, Fujian and Guizhou as the first ecological civilization test area in the country, and marks that the construction of the ecological civilization test area in China enters the comprehensive development and accelerated promotion stage. Under the background, the method has practical significance in treating pollutants such as livestock and poultry manure, domestic garbage and the like in the region.
The preparation of biogas by anaerobic fermentation is the most mainstream treatment technology of livestock and poultry feces at present. However, research shows that the current breeding industry in China is not standard, small in scale and large in quantity, and the stable supply of fermentation raw materials is restricted. Meanwhile, the following problems exist in the production process to restrict the industrial development of the production process:
(1) the byproducts are difficult to be absorbed, and the economic benefit of the project greatly fluctuates. The biogas manure market as an important income source is still cultivated, the market demand is not clear, stable economic income is difficult to form, a large amount of biogas slurry is difficult to treat, and the unavailable biogas residue and biogas slurry cause secondary pollution to the environment.
(2) The problem that heavy metals and antibiotics in the livestock and poultry feces generally exceed standards is difficult to solve. Heavy metals and antibiotics in the biogas residues and the biogas slurry after anaerobic fermentation generally exceed standards, soil pollution is caused by continuous application of the organic fertilizer, and the heavy metals and the antibiotics finally enter human bodies through food to harm the health of the human bodies.
