Description
Technical field
The present invention relates to a kind of inorganic agent and production method thereof of farm animal excrement, especially feces of livestock and poultry is carried out the method that harmless treatment makes it to become the crops fertilizer.
Background technology
Current, our country begins pay attention to day by day to food safety, the enforcement of pollution-free food, non-polluted farm product, ecological agriculture plan, and the livestock and poultry breeding industry development is swift and violent, and livestock and poultry cultivation has become the important channel of growth of agricultural efficiency, increasing peasant income.Because livestock and poultry breeding industry is fast-developing, the pollution of farm animal excrement increases the weight of day by day.At present, the big-and-middle-sized livestock and poultry farm of China (referring to 10,000 above pig farms, 100 above cattle farms and the above chicken house of 100,000 plumages) has reached more than 14800, and focuses mostly near coastal big and medium-sized cities, east." People's Republic of China's noxious waste pollution environment is prevented method of treatment " being carried out check result in 2003 according to the National People's Congress and show that China's large-scale cultivation field feces of livestock and poultry generation reaches 21.6 hundred million tons, is 2.7 times of industrial solid castoff.Because the feces of livestock and poultry generation is very big, the livestock and poultry farm 80% or more is comprehensive utilization and sewage treatment facility not, and the facility of having built more than 70% is with to equip also not good enough because of treatment process, equipment performance difference etc. former thereby fail to play a role; Caused the serious environmental pollution, wherein to pollute the proportion account for bigger in the intensive culture field, and the garbage of many livestock and poultry farms can not get timely processing; The long-term stacking let alone to expose to the sun and rain, and causes the interior mosquitos and flies evil of colony house to be given birth to; Pestilence spreads; The laying rate of poultry descends, and mortality of livestock increases, and loss of enterprises is heavy; Livestock and poultry breeding industry feces serious threat that even more serious is and the regional environmental quality that influence big and medium-sized cities cause seriously " solid " pollution to water source, soil, air and the biology of surrounding.According to expert introduction; If poultry give birth to excrement without biological decomposition; Plant does not absorb; Directly advance people's soil and also can cause worm's ovum, germ contamination and uric acid to kill and wound plant, as the bird flu of wide-scale distribution lets people feel startling in Asia area then, the bird flu virus 180d of in feces of livestock and poultry, can surviving; Pollute the big public hazards become society, seriously restricted the sustainable development of agricultural production, therefore, the feces of livestock and poultryization evil of how accumulation being caused disaster is treasured, carries out innoxious, recycling treatment and has become a global problem.
Feces of livestock and poultry is a kind of environmental hazard material of reality; Be again a kind of available living resources; Utilizing improper to it will be serious polluter; If realize harmless treatment, can bring into play the effect of resources such as feces of livestock and poultry biomass energy, refuse nutrition to a great extent, realize the utilization again of waste resource.At present, the processing method of feces of livestock and poultry mainly contains following several kinds both at home and abroad.
1, directly does fertilizer or sanitary landfills; This method is that feces of livestock and poultry directly is put in the cropland or imbeds underground landfill, through the biochemical action of microorganism in the ground, makes it to be decomposed into plant absorbing; But stated on this method; Undecomposed feces of livestock and poultry plant does not absorb, and directly advances people's soil and also can cause worm's ovum, germ contamination and uric acid to kill and wound plant, and landfill is land occupation, polluted underground water and surrounding in a large number again.
2, this method of burning disposal is mainly used in the feces that the strong pathogenic bacteria brood cell of resistance pollutes, and the general using incinerator carries out harmless treatment with feces of livestock and poultry.Can be used for generating etc. though burning method produces a large amount of heat energy, a large amount of feces water content that China intensive culture field produces are high, and drying is difficulty relatively, are difficult to as fuel as not handling; Simultaneously, burn and to discharge a large amount of harmful substances, cause second environmental pollution, thereby application prospect is little.
3, as feedstuff; Contain nutritional labelings such as a large amount of nitrogens, mineral, cellulose in the feces; But contain many potential harmful substances in the feces of livestock and poultry simultaneously; Like mineral trace element (copper, zinc, arsenic etc.), various medicines (anticoccidial drug, sulfa drugs etc.), antibiotic and hormone etc., and a large amount of pathogenic microorganisms, parasite and ovum thereof.So feces of livestock and poultry has only through after certain technical finesse, can be as the feedstuff of fish, pig or cattle, but its processing procedure is comparatively complicated, cost is high and feed quality is relatively poor, applies thereby limited it.
4, anaerobic fermentation producing methane; Anaerobic fermentation is the method for a kind of effective processing feces of livestock and poultry and resource recycling, can not only solve the fecal pollution problem of livestock and poultry farm, and the biogas of fermentation can directly supply peasant household to use; Natural pond liquid and natural pond slag can utilize again, meet ecological principle.Its shortcoming is NH
3Volatilization loss is many, and the treatment pond volume is big, and can only on-the-spot disposal and utilization.Because natural pond liquid utilization receives the agricultural cultivating mode of territorial environment, crop species to limit bigger; The bottleneck that makes the present anaerobic fermentation biogas engineering operation of effectively being treated as of natural pond liquid; And construction investment is high, payoff period is long, so owner's enthusiasm is not high, anaerobic fermentation technology is applied and is restricted.
5, aerobic compost is handled; Aerobic compost is exactly under Artificial Control; Under certain humidity, temperature, C/N ratio and ventilation condition; Utilize the Fermentation of microorganisms such as the extensive antibacterial that distributes of nature, actinomycetes, fungus, promote the microbiological process of biodegradable Organic substance artificially to stable humus biochemical conversion.Aerobic compost handle be realize that feces of livestock and poultry is innoxious, a kind of effective method the most of minimizing, resource, industrialization; Have advantages such as operating cost is low, treating capacity big, non-secondary pollution because of it, become a research focus in countries in the world resource, environmental protection field in recent years.Various pathogenic bacterias and weed seed that the composted process not only can be killed in the feces make feces reach innoxious, also can generate in a large number the available nutrient that can be utilized by plant absorbing, and synthetic new humus, are the important substance that constitutes soil fertility; Handling sophisticated compost and be not only a kind of fine fertilizer, still is a kind of good soil conditioner, can improve the physicochemical property of soil.Adopt compost method to handle feces of livestock and poultry, the end product foul smell of processing is less, and dry, packs easily, spreads fertilizer over the fields.Shortcoming is that NH is arranged in the processing procedure
3Loss, can not control foul smell fully, the place that compost needs is big, the processing time is long.
