Description
Technical field
The utility model belongs to changing food waste processing and utilizing technology field, relates in particular to a kind of closed horizontal double-layer barrel aerobic fermentation tank.
Background technology
Changing food waste is topmost a kind of in food refuse, comprises food process leftover bits and pieces (kitchen is remaining) and edible remaining (hogwash) that family, school, dining room and catering industry etc. produce.Its complicated component, is mainly the mixture of the many kinds of substances such as oil, water, pericarp, vegetables, rice and flour, fish, meat, bone and useless tableware, plastics, paper handkerchief, chemical composition, has starch, cellulose, protein, lipid and inorganic salts.China's changing food waste quantity is very huge, and is fast rise trend.
Changing food waste has the dual character of significant harm and resource, and its feature can be summarized as: (1) moisture content high, can reach 80%-95%.(2) salt content is high, some areas are high containing capsicum, acetic acid.(3) high, the protein of content of organics, cellulose, starch, fat etc.(4) be rich in nitrogen, phosphorus, potassium, calcium and various trace element.(5) have pathogen, pathogenic microorganism.Perishable, rotten, smelly, grow mosquito.
Aspect waste resource, according to the relevant expert of Ministry of Agriculture measuring and calculating, changing food waste includes a large amount of nutriments, 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 explains, pressing dry matter content calculates, 5000 ten thousand tons of changing food wastes are equivalent to the high-quality feed of 5,000,000 tons, and the energy equivalence including is in the Energy output amount in annual 1000 ten thousand mu of arable lands, and the protein including is equivalent to the protein quantum of output of annual 2000 ten thousand mu of soybean.That is to say, if the changing food waste of 1 year output of China 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, need every year the present situation of a large amount of food import feeds, rationally utilizing changing food waste is the effective way that increases resource utilization, solves to a certain extent China's food problem.And this utilization, meets minimizing, recycling, resource feature, it is the lively case of developing a circular economy.
For changing food waste harmfulness mainly contain following some:
(1) contaminated 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 standing time 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 leakage water and foul gas, grows mosquito, and environmental sanitation is made a very bad impression.
(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 product is provided, livestock is after directly eating food without the changing food waste of effectively processing, the homology that " cannibalism " easily occurs is polluted, and cause the cross infection of epidemic disease between people and animals, be detrimental to health, and may promote the propagation of some fatal disease.As the infectious disease of large-scale outbreak in history.Say for another example, at present in the cause of many local bird flus of propagating etc., may be that the corpse due to sick ox, sick sheep or sick pig has been made into animal feed, thereby 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 producing while stacking in changing food waste enters into sewage disposal system, can cause the increase of content of organics, thereby increase the weight of the burden of sewage treatment plant, increases operating cost.
At present, changing food waste is generally adopted to composting process, idiographic flow is: unified recovery enters after process for producing line, through sorting, magnetic separation, the inorganic matters such as chopsticks, polybag, metal are sifted out, and remaining kitchen castoff, after fragmentation, water-oil separating, dehydration, send into aerobic fermentation equipment, the kitchen castoff after processing becomes industrial grease and Nutrition Soil.And aerobic fermentation equipment is the key that determines that Nutrition Soil is processed, existing aerobic fermentation equipment has complex structure, treating capacity is little, and fermentation period is long, and attenuation degree is inhomogeneous, poor processing effect, and the defect such as automaticity is low, needs badly further and is improved.
