Description
Technical Field
The invention relates to the technical field of cultivation waste treatment, in particular to a pig raising excrement conversion and utilization device with a dry-wet separation function.
Background
With the continuous development of economy and society in China, the living standard is rapidly improved, the demand of residents on meat and egg foods is rapidly increased, the domestic livestock and poultry breeding industry is in a rapid development trend and tends to be stable, the pork yield reaches 5299 million tons and accounts for 45.5 percent of the world total amount, and the livestock and poultry breeding industry gradually becomes the most active growth point and the main supporting industry in agricultural economy in China. However, with the improvement of the intensification degree of the farm, the farm is separated from the planting industry, a large amount of excrement is not consumed, the breeding wastewater is discharged out of order, and the like, which is the reason for the large discharge amount of phosphorus in the breeding industry in China and is one of the sources of non-point source pollution of agriculture in China.
With the development of pig raising scale in China, the manure discharge of pig farms is one of the largest pollution industries in China, and although pig raising wastes have more environmental risks, the pig raising wastes are carriers of nutrients and energy and are special agricultural resources, so that the pig raising wastes distributed in small and medium-sized pig farms in rural fields are used for irrigating farmlands for a long time in large quantities, the physical and chemical properties of soil are easily deteriorated, the air permeability and the water permeability of the soil are reduced, and steep growth, lodging, late maturity or immature maturity, yield reduction and even large-area rotting of crops are caused. Improper treatment of pig raising wastes is also prone to breeding mosquitoes and flies, spreading pathogens and further harming human and livestock health. In addition, ammonia, hydrogen sulfide and mercaptan substances in the pig raising waste are main sources of odor pollution, so that the air quality is influenced, and the health of people and livestock is also endangered. Therefore, the problem that the pig raising waste is treated by adopting a reasonable technical means becomes an urgent need to be solved in the existing pig raising industry. In the prior art, three methods are commonly used for treating pig raising wastes: aerobic composting, anaerobic fermentation and thermochemical treatment.
Thermochemical treatment methods include hydrothermal, wet oxidation, incineration, gasification, thermal cracking, and the like. Thermochemical treatment techniques have several common advantages: 1. the range of the solid waste which can be treated is wide, and the solid waste can be treated in a dry or wet manner, has single or complex components, and can be treated in a municipal or agricultural manner; 2. the added value of the product is high, the application is wide, and the resource utilization is realized; 3. belongs to a harmless and quantitative reduction technology, can effectively kill pathogenic bacteria, degrade organic pollutants, reduce the volume of waste and reduce the landfill pressure of urban land. The thermochemical treatment technology is generally only suitable for municipal refuse treatment, and has the disadvantages of high cost, complex treatment procedure, high energy consumption and difficult popularization when being used for treating the excrement of the live pigs.
An aerobic composting method, namely a waste stabilizing and humification process for realizing the aerobic degradation of organic matters and killing pathogenic bacteria at high temperature by microorganisms by artificially controlling the conditions of carbon-nitrogen ratio, water content, pH value, temperature, ventilation quantity and the like of materials of easily degradable organic wastes. In the aspect of treating the pig raising wastes, the pig raising wastes have certain market with the advantages of simple operation, low treatment cost, thorough decomposition of organic matters, good deodorization and sterilization effects, product fertilizer application and the like. However, in the specific operation process, because the type of the feed used by the farmers in the process of feeding the live pigs is not used, the composition of the excrement of the live pigs is different, meanwhile, in the specific implementation process of the aerobic composting method, the difference in the aspects of the control mode and the like can greatly affect the flora of microorganisms, the quality of the compost products and the surrounding environment of the plant area, and the aerobic composting technology still has the problems of serious greenhouse gas emission, difficult treatment of percolate, uneven quality of the compost products, heavy metal pollution risk in the subsequent application and the like. The aerobic composting method has complicated steps, long period in the specific implementation process and high cost of required equipment, so the aerobic composting method is not widely applied in the actual production process.
The anaerobic fermentation method is one of the traditional ways for realizing resource utilization of organic wastes. The technology can effectively convert organic matters into methane and carbon dioxide to burn and generate electricity mainly through assimilation of anaerobic bacteria. Therefore, the method is already in the farming era, and the technology is widely applied. However, the existing anaerobic fermentation has the following problems: firstly, three processes of low-temperature fermentation, medium-temperature fermentation and high-temperature fermentation are generally needed in the process of fermenting the pig manure, and the existing anaerobic fermentation tank cannot realize accurate temperature regulation and control. The method is widely applied to the treatment of the live pig manure through wet anaerobic fermentation and medium-high temperature anaerobic fermentation. The PH value required by anaerobic fermentation is generally 6.5-7.5 from the viewpoint of ensuring the methane production; from the viewpoint of stabilization of organic matter, the retention time is generally 20 to 30 days. However, the pig manure contains a large amount of organic matters containing refractory components such as wood fibers and the like, so that the effect of anaerobic fermentation of the pig manure is reduced; in addition, the conventional anaerobic fermentation of the pig manure is limited by the fermentation temperature, so that a large amount of pathogenic bacteria are remained in the pig manure.
