Description
Technical field
The utility model belongs to technical field of waste treatment, particularly relates to a kind of extremely livestock and poultry and changing food waste and comprehensively produces commercial grease and fertilizer system.
Background technology
Dead livestock and poultry (carcase) are the special production of a class, domestic refuse.Spread disease, endanger food safety, harm ecotope, impact economic order, be that four of carcase endanger greatly, and the accident made a very bad impression can be caused thus.The domestic animal died of illness, the most death because having suffered from certain transmissible disease of poultry.Wherein have some to be transmissible diseases of infecting both domestic animals and human, as anthrax, tuberculosis, rabies etc., as these livestock meat of dying of illness edible, people with regard to easy infected these diseases upper, this healthy very harmful to people.Although some livestock and poultry is not dead because of transmissible disease, after death, the Salmonellas in body, intestinal bacteria, Bacillus proteus etc., will also be disseminated to rapidly in the muscle of livestock and poultry by amount reproduction, some bacteriums can also produce enterotoxin, if people has eaten the meat of this livestock and poultry, will poison by food.Some poultry may be poisoned to death because of the foodstuff eating contaminated highly toxic pesticide, if people has eaten this dead livestock and poultry, equally also likely poisoning, even causes death.Therefore, for dying of illness or the livestock and poultry of dysoemia, harmless treatment must be carried out according to the relevant regulations of administrative department for animal husbandry and veterinary of State Council, must not arbitrarily dispose.According to the provisions of the relevant regulations issued by the State and and the practical situation in rural area, dead livestock and poultry should take following way to carry out harmless treatment: the livestock and poultry of dead livestock and poultry, dysoemia are forbidden to appear on the scene, transfer the possession of, sell, abandon, and should meet the place destruction of animal epidemic prevention condition.The big-and-middle domestic animal such as horse, ox, pig, sheep is dead burns latter buried less than 2 meters without exception.The animalcule such as poultry, rabbit is dead burns latter buried less than 1.5 meters without exception.
Changing food waste is topmost one in food refuse, comprises the food process tankage (kitchen is remaining) of the generations such as family, school, dining room and catering industry and edible remaining (hogwash).Its complicated component, the mainly mixture of the many kinds of substance such as oil, water, pericarp, vegetables, rice and flour, fish, meat, bone and useless tableware, plastics, paper handkerchief, chemically on composition, have starch, Mierocrystalline cellulose, protein, lipid and inorganic salt.China's changing food waste quantity is very huge, and in quick ascendant trend.
Changing food waste has the duplicity of significant harm and resource, and its feature can be summarized as: (1) water ratio high, 80%-95% can be reached.(2) salt content is high, some areas are high containing capsicum, acetic acid.(3) organic content high, protein, Mierocrystalline cellulose, starch, fat etc.(4) be rich in nitrogen, phosphorus, potassium, calcium and various trace element.(5) have pathogenic bacteria, pathogenic micro-organism.Perishable, rotten, smelly, grow mosquito.
In waste resource, according to Ministry of Agriculture relevant expert measuring and calculating, changing food waste includes a large amount of nutritive substances, and main component is grease and protein, alternative corn, fish meal, dregs of beans etc. are processed into high energy protein high-quality feed, are also the applicable raw materials of preparing biological diesel oil.Expert interpretation, calculate by dry matter content, 5000 ten thousand tons of changing food wastes are equivalent to the high-quality feed of 5,000,000 tons, and the energy equivalence included is in annual 1000 ten thousand mu of energy quantums of output of ploughing, and the protein included is equivalent to the protein quantum of output of annual 2000 ten thousand mu of soybean.That is, if the changing food waste of China's 1 year output is all utilized, be equivalent to save 1,000 ten thousand mu of arable lands.In the face of Chinese arable land is nervous, food shortage, the annual present situation needing a large amount of food import feed, Appropriate application changing food waste is the effective way increasing resource utilization, solve China's food problem to a certain extent.Further, this utilization, meets minimizing, recycling, resource utilization feature, is the lively case of developing a circular economy.
For changing food waste hazardness mainly contain following some:
(1) contaminate environment, affect the appearance of the city.Because changing food waste contains higher organic matter and moisture, be easily subject to the effect of microorganism, and the phenomenon that rots; And discarded storage period is more of a specified duration, putrid and deteriorated phenomenon is just serious all the more.Particularly to summer, temperature is higher, rots also faster, at this time easily produces a large amount of water from diffusions and foul gas, grows mosquito, make a very bad impression to environmental health.
(2) be detrimental to health.Meat proteins in changing food waste and the lipoid material of animality, mainly come from those livestock poultry that meat-based food is provided, livestock is after the changing food waste of directly eating food without effectively process, the homology of easy generation " cannibalism " is polluted, and cause the cross infection of epidemic disease between people and animals, be detrimental to health, and the propagation of some fatal disease may be promoted.As the transmissible disease of large-scale outbreak in history.Say for another example, the cause of the bird flus etc. of propagating in many places at present, may be because the corpse of sick ox, sick sheep or sick pig has been made into animal-feed, thus cause the extensive infection of disease.
(3) spread disease.The outdoor storage of changing food waste can cause the amount reproduction of mosquitos and flies mouse worm, and it is the main media that disease spreads.
(4) the lower sepage produced when stacking in changing food waste enters into Sewage treatment systems, can cause the increase of organic content, thus increase the weight of the burden of sewage work, increases running cost.
At present, aerobic compost or anaerobic digestion producing methane technique are generally adopted to changing food waste, idiographic flow is: after unified recovery enters process for producing line, through sorting, magnetic separation, sifted out by the inorganicss such as chopsticks, plastics bag, metal, remaining kitchen castoff, after fragmentation, oily water separation, dehydration, send into aerobic fermentation equipment, the kitchen castoff after process becomes industrial grease and Nutrition Soil.Anaerobic digestion process, pre-treatment and aerobic compost pre-treatment basically identical, after carrying commercial grease, slurrying feeding anaerobic jar carries out anaerobically fermenting, produce biogas, afterwards by centrifugation, natural pond slag is carried out to mixture, natural pond liquid is separated, and natural pond slag is as the raw material of fertilizer processed, and natural pond liquid processes qualified discharge further.Existing to the natural pond slag after anaerobic digestion of kitchen wastes, generally take to add flocculation agent precipitation add caliche after, filter press, dewater to less than 55%, landfill disposal.One is cause organic resources to waste, and two is that equipment investment is large, and processing cost is high, and three is landfill land occupation resources.And take centrifuge dehydration aerobic fermentation process, the social utilization ratio of resource can be improved, produce good Social and economic benef@.
For the comprehensive treating process of dead livestock and poultry and changing food waste, can purify living environment like this, make full use of resource, take up an area space less, produce Social and economic benef@, therefore this is the difficult problem needing solution badly.
