Description

Municipal sludge or the airtight aerobic biological organic fertilizer system processed of meal natural pond, kitchen slag
Technical field
The utility model belongs to Assessment of MSW Disposal Technologies field, relates in particular to a kind of municipal sludge or the airtight aerobic biological organic fertilizer system processed of meal natural pond, kitchen slag.
Background technology
Changing food waste is topmost a kind of in food refuse, comprises food process tankage (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 constitution, has starch, Mierocrystalline cellulose, protein, lipid and inorganic salt.China's changing food waste quantity is very huge, and is fast rise trend.
Changing food waste has the duplicity of significant harm and resource, and its feature can be summarized as: (1) water ratio high, can reach 80%-95%.(2) salt content is high, some areas are high containing capsicum, acetic acid.(3) high, the protein of organic content, 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.
Aspect waste resource, according to the relevant expert of Ministry of Agriculture 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 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 utilization feature, it 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 diffusion and foul gas, grows mosquito, and environmental health 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-based food 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 transmissible 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 treatment systems, can cause the increase of organic content, thereby increase the weight of the burden of sewage work, increases running cost.
At present, changing food waste is generally adopted to aerobic compost or anaerobic digestion producing methane technique, idiographic flow is: unified recovery enters after process for producing line, through sorting, magnetic separation, the inorganicss such as chopsticks, plastics bag, metal are sifted out, and remaining kitchen castoff, after fragmentation, oily water separation, dehydration, send into aerobic fermentation equipment, the kitchen castoff after processing becomes industrial grease and Nutrition Soil.Anaerobic digestion process, pre-treatment and aerobic compost pre-treatment are basically identical, proposing after commercial grease slurrying sends into anaerobic jar and carries out anaerobically fermenting, produce biogas, afterwards mixture is carried out to natural pond slag by centrifugation, natural pond liquid is separated, and natural pond slag is as the raw material of fertilizer processed, and natural pond liquid is further processed qualified discharge.Existing to the natural pond slag after anaerobic digestion of kitchen wastes, generally take to add that flocculation agent precipitation adds after caliche, filter press, dehydration is to below 55%, landfill disposal.The one, cause organic resources waste, the 2nd, equipment investment is large, and processing cost is high, and the 3rd, landfill land occupation resource.And take centrifuge dehydration aerobic fermentation process, and can improve the social utilization ratio of resource, produce good society and economic benefit.
Mud is the product after sewage disposal, is a kind of extremely complicated heterogeneous body being comprised of organic relic, bacterium thalline, inorganic particle, colloid etc.The main characteristic of dewatered sludge is water ratio high (more than 80%), and organic content is high, easily degenerates smellyly, causes serious atmospheric pollution, affects resident's life; And particle is thinner, proportion is less, is gluey liquid.It is the concentrated thing between liquid and solid, can transport with pump, but it is difficult to carry out solid-liquid separation by sedimentation.
Natural pond, meal kitchen slag (the natural pond slag after changing food waste anaerobically fermenting) and dewatered sludge in city, can make full use of resource like this, takes up an area less space, produces society and economic benefit, is therefore a difficult problem of needing solution badly.
