Description

Changing food waste water-oil separating integrated equipment for wastewater treatment

Technical field

The invention belongs to a kind of refuse treatment engineering technical field, relate to a kind of changing food waste treatment facility, especially relate to a kind of changing food waste water-oil separating integrated equipment for wastewater treatment.

Background technology

Along with improving constantly of China's constant development of economy and living standards of the people; The catering trade in each city has also got into the high speed development stage; But thing followed house refuse, changing food waste are seriously polluting urban environmental hygiene, bring great harm for the life health of numerous people.

Changing food waste is commonly called as " swill "; It is the residue after the meal of food and beverage enterprises such as hotel, dining room, dining room and family; Mainly comprise rice and wheaten foods remnants, vegetables, vegetable oil, animal oil, meat bone class, fishbone etc., the animal and plant wet goods contains the organic substance of abundant biomass energy.Changing food waste is a kind of potential resource that receives long-standing neglect, owing to utilize improper many social concerns that produced.With regard to quantity, the discharge capacity of big city such as Beijing, Shanghai every day all surpasses kiloton, and medium-sized city such as Ningbo, Chengdu also all has to surpass hundreds of tons every day.

At present, China's rapid economic development urban population increases rapidly, and the people's lives level improves constantly, and urban restaurant trade is become increasingly prosperous, and the generation of changing food waste is unprecedentedly increased.The National urban sales of the catering industry were 10,345 hundred million yuan in 2006, reached 12,352 hundred million yuan in 2010, every year on average with 17.9% speed increment.Do not comprise small-sized cities and towns, annual more than 2,000 ten thousand tons of the changing food wastes that produce in national big and medium-sized cities.

Compare with other domestic wastes; The changing food waste water content is high, content of organics is high, and fat content and salt content are high, and poisonous and harmful substance (like heavy metal etc.) content is few; But the speed that rots is fast; It is perishable rotten to be prone to grow bacterium, particularly high temperature season, causes a large amount of rapidly breedings of harmful substances such as pathogenic microorganism, mycotoxin.Therefore, if can not get dealing carefully with, will cause adverse effect to environment and health.

Existing changing food waste treatment technology mainly comprises both at home and abroad: physics fragmentation, high temperature aerobic composting, anaerobic fermentation, earthworm are handled, dried heat is handled.These technology all have application abroad, and have obtained certain effect.

American-European developed country is because the changing food waste generation is less, and it is main that its processing mode pours sewer with the physics fragmentation, but this processing mode is also incompatible to the big national conditions of Chinese changing food waste generation, can increase the processing load of sewage treatment plant on the contrary.

Current, domestic changing food waste treatment technology mainly is to adopt/anaerobic organism fermentation or heat treated mode, and its product mainly contains two kinds of fertilizer and protein feed raw materials.But owing to contain rich nutrient substances in the changing food waste, more development trend is that its processing is processed as the protein feed raw material, so not only makes resource obtain utilizing, and more can effectively alleviate the situation of " people and animals strive grain ".But; Most of technology just directly is processed into the protein feed raw material after with changing food waste letter sorting, preliminary treatment, dehydration, drying; And ignored the risk that changing food waste exists as feed; Then possibly there are the problem of potential safety hazard in pathogenic microorganism wherein and animal derived materials if can not deal carefully with.In 20 end of the centurys, worldwide popular of livestock and poultry communicate illness such as rabid ox disease, itch makes people recognize that fully homology eats the seriousness of problem mutually.Therefore, a kind of method of utilizing producing protein feed material by utilizing food wastes is provided at present,, reduces homology phase eating habit danger to ensure meal kitchen class feed product quality.

Dining room rubbish mainly contains two kinds through the prior art that anaerobic fermentation obtains biogas at present:

The first obtains biogas from refuse landfill.The advantage of this method is that procurement cost is low, treats that the landfill yard landfill waste is abundant, and normally when being about to closing, direct cannulation goes into by the extraction of landfill waste depths to get final product.The shortcoming of the method is that anaerobic methane production efficient is poor, and atmosphere pollution.This is because landfill yard is in wide-open environment; In the rubbish can the rotten organic matter overwhelming majority be to become thoroughly decomposed at good oxygen condition (or half good oxygen condition); Several years such as have only even make more than 10 years when before enough thick rubbish cover layer (generally about 10 meters) being arranged by the landfill waste top; Could really make before to be in anaerobic state by landfill waste, but this moment in the rubbish can rotten organic matter seldom.But we can feel still that sometimes the category sludge gas amount is very big, and that only is because by the quantity of refuse of the landfill cause that is too big really.Though so scheme is cheap, the anaerobic methane production poor efficiency can not obtain high benefit.

It two is rubbish to be stored in the airtight container through anaerobic fermentation obtain biogas.The advantage of this method is that to obtain biogas efficient high because in the rubbish can rotten organic matter be in basically fully become thoroughly decomposed in the anaerobic environment stable.Weak point is that to expend cost too high, mainly expends: gentle circulation ventilation etc. is pulverized, forces to stir, added to refuse classification (organic waste is sorted out), organic waste.All these cost costs all are to become thoroughly decomposed as early as possible in order to quicken organic waste, shorten the anaerobic fermentation cycle, generally can be controlled in 30 days.The enough subsidies of anarchy although consequently the biogas benefit is fine, but still are not enough to offset cost, if will be difficult to keep on the go.Though so scheme anaerobic methane production efficient is high, cost is too high, can not obtain high benefit.

Existing storing bulk material silo generally adopts steel construction or reinforced concrete structure, accomplishes in case build, and its warehouse height all is changeless.The warehouse material is except that satisfying the requirement of strength; Adequate thickness also must be arranged to form the rigidity that whole silo body has resistance to deformation; So just can guarantee no matter buy securities with all one's capital or hole capital after selling all securities in the silo; Whole silo body all is stable, and we are referred to as " rigidity silo " this silo, and existing silo belongs to the rigidity silo basically.

Because of the warehouse thickness of rigidity silo is to thicken with the silo capacity, so if build big capacity rigidity silo, cost can be very expensive.

The dining room discarded object has the characteristics of himself, when carrying out sanitary landfills, has problems such as floor space is big, secondary pollution, potential safety hazard; It is maximum to burn the minimizing degree, and initial investment and operating cost are higher, processing procedure possibly produce danger wastes such as bioxin, flying dust, receive common people's degree of awareness to limit and supervise restriction, and burning disposal is still promoted difficulty; The compost treatment organic solid castoff exists then that heavy metal is difficult to separate, nitrogen loss is serious, energy consumption is big, shortcomings such as the high and difficult collection of odorous gas concentration.

Anaerobic fermentation is under anaerobic, and it is CH that organic matter is carried out decomposition and inversion 4And CO 2Process.Have following advantage: (1) floor space is little, the processing cycle short; (2) sweat can produce methane as clean energy source and high-quality humus fertilizer; (3) sweat is controlled easily, does not produce secondary pollution; (4) but complete closed handle, can not pollute surrounding enviroment.

More to anaerobic fermentation research at present, the fermentation of individual event anaerobic fermentation and diphasic anaerobic is arranged; Mesophilic digestion and hot fermentation; Wet type fermentation, dry type fermentation and half dry type fermentation.

Anaerobic fermentation in the past is often to single material; Carbon-nitrogen ratio, moisture content, acid-base value etc. are in smaller scope; Need the parameter of adjusting many; Particularly the single fermentation material can produce feedback inhibition to methane backeria, has the ammonia nitrogen concentration height, has inhibitory action, fermentation load to hang down the characteristics such as solid holdup is low that reach to methanogen and hydrogenogen like manure fermentation; Changing food waste has that oil content is big, foreign matter is many, solid holdup is high, the characteristics of the easy acidifying of fermentation substrate; Domestic waste has that the content of organic matter is low, composition is big with the space-time fluctuation, the characteristics big to the anaerobic fermentation system impulsive force.Build treatment facility respectively to various discarded objects in addition, investment is big and be difficult to bring into play the scale effect.Particularly the inhibition factor of single material is obvious, and material adjusting difficulty is very big.

The dining room discarded object carries out anaerobic fermentation after the preliminary treatment; Can solve that the fermentation materials homogenieity is poor, fermentation efficiency is low, the tunning inhibitory action; Can enlarge simultaneously the biogas scale of producing; Promote liquid natural pond, natural pond slag quality, focus on various organic solid castoffs, improve the level of resource, innoxious and minimizing.

Changing food waste is different from other discarded objects (house refuse, industrial refuse, TRADE REFUSE, agricultural wastes etc.), and its characteristics are: 1, moisture content is high, about 72% (removal free water)-92% (containing free water); 2, complicated component, content of organics is high, about 90% (dry weight); 3, fat content is high; 4, contain anaerobic fermentation is had inhibiting salt; 5, because of not classification, contain 10% the impurity (being mainly chopsticks, plastics, paper, little metal, cutlery box, packing material etc.) of having an appointment, post-processed equipment (fermentation, dehydration, pipeline etc.) is had a negative impact.

The main method of present processing utensil rubbishes; Be that organic waste is handled through operations such as grease separation, preliminary sorting, Mechanical Crushing, hydraulic pulping, allotment slurry, anaerobic fermentations; Make changing food waste degrade fully; Finally decomposite biogas through anaerobic digestion, biogas after desulfurization is handled as using energy source; The natural pond slag is produced the high-quality fertilizer through control oxygen compost; Isolated grease can be recycled as regeneration raw material of industry oil.At the waste water reusable edible that processing procedure produces, final unnecessary waste water is through qualified discharge after the biochemical treatment; The foul smell that rubbish produces in the processing procedure is handled directly discharging of back up to standard through biofiltration.This processing method complex technical process, energy consumption is higher; The equipment that needs is many, and investment is high.

At present, the whereabouts of changing food waste mainly contains direction: the one, do not add processing and feed " swill pig " as raw material, through the food chain harm humans in virtually; The 2nd, from changing food waste, pulled out " waste oil " by some illegal retailers and be processed into " edible oil " and come into the market again, the grievous injury consumer health jeopardizes food security; The 3rd, directly discharge as rubbish, not only stop up the urban sewage pipeline, distribute rancid smell, and the severe contamination water source, environmental sanitation is caused enormous pressure.

Therefore, the integrated processing of changing food waste water-oil separating safely and efficiently can realize good changing food waste being carried out resource, harmless treatment, both can stop the harm of swill from the source, can alleviate the china natural resources problem of shortage again.
