Description

A kind of system being applied to changing food waste process
Technical field
The invention belongs to changing food waste process applied technical field and in particular to a kind of be applied to changing food waste process be System, improves the treatment effeciency of kitchen rubbish rubbish and changing food waste resource maximally utilizes rate.
Background technology
Changing food waste, is commonly called as hogwash, also known as water from washing rice, swill, is the sanitary waste that resident is formed during personal consumption, Easily rot, distribute stench, spread germs and virus.Changing food waste main component include meter dough-making powder group food remaining, Vegetable, vegetable and animals oils, meat bone etc., chemically on composition, have starch, cellulose, protein, lipid and inorganic salt.
Food waste be mainly characterized by content of organics enrich, moisture high, perishable, its character and abnormal smells from the patient all can kitchen Garbage disposal makes a very bad impression to environmental health, and easily grows the harmful substances such as pathogenic microorganism, mycotoxin.One minute Front or delicacies, became rubbish after one minute.Due to cooking culture and custom of having a dinner party, changing food waste has become Chinese exclusive showing As Chinese dining table wastes surprising, the daily changing food waste producing flood tide, from the numeral of Development in Beijing reform committee, Beijing Produce daily 1200 tons of changing food wastes, environment system of Tsing-Hua University solid waste pollution control and Resource analysis statistical data Show, Chinese city produces changing food waste every year and is not less than 60,000,000 tons, changing food waste is topmost one kind in food refuse, Food process leftover bits and pieces (food waste) including generations such as family, school, dining room and catering industries and edible remnants (hogwash).It becomes Point complexity, mainly oil, water, peel, vegetable, rice and flour, fish, meat, bone and the many kinds of substance such as useless tableware, plastics, napkin Mixture.China's changing food waste quantity is very huge, and is in rapid increase trend.Changing food waste has significant harm and resource Dual character, its feature can be summarized as:(1) moisture content is high, up to 80%-95%;(2) salt content is high, some areas contain Fructus Capsici, Acetic acid is high;(3) content of organics height, protein, cellulose, starch, fat etc.;(4) it is rich in nitrogen, phosphorus, potassium, calcium and various micro unit Element;(5) there is pathogen, pathogenic microorganism;(6) perishable, rotten, smelly, grow mosquito.
Changing food waste unification is pressed solid waste treatment method and is processed, and processing method mainly has Physical, chemical method, bioanalysises Deng, specific treatment technology has the modes such as landfill, burning, compost, fermentation, regardless of whether being Physical, chemical method, bioanalysises etc., It is all to be respectively processed to separate with municipal sewage plant, and treatment effeciency is low and maximization that cannot realize kitchen resource Reuse, and this is current urgently to be resolved hurrily.
Therefore, based on the problems referred to above, the present invention provides a kind of system being applied to changing food waste process.
Content of the invention
Goal of the invention:It is an object of the invention to provide a kind of system being applied to changing food waste process, the conjunction of its design structure Reason, in operation, changing food waste is directly combined with municipal sewage plant, realizes efficiently reusing of resource, and processes ring Guarantor, the phenomenon of non-secondary pollution.
Technical scheme:The present invention provides a kind of system being applied to changing food waste process, including changing food waste pretreatment dress Put, and the mix and blend pond being connected with utensil garbage pre-processing device, and the digester being connected with mix and blend pond, and with digestion Tank connected mixing arrangement, and the SBR nitrogen rejection facility being connected with mixing arrangement, and the Sewage Plant work being connected with SBR nitrogen rejection facility Property Aeration tank.
The technical program, the described system being applied to changing food waste process, also include sending out with the tank connected biogas of digestion Electric installation.
The technical program, the described system being applied to changing food waste process, also include the burning being connected with mixing arrangement Device.
Compared with prior art, the having the beneficial effects that of a kind of system being applied to changing food waste process of the present invention:Its Rationally, in operation, changing food waste is directly combined design structure with municipal sewage plant, realizes efficiently reusing of resource, And process environmental protection, the phenomenon of non-secondary pollution.
Brief description
Fig. 1 is a kind of system schematic being applied to changing food waste process of the present invention;
Wherein, in figure sequence number mark is as follows:1- utensil garbage pre-processing device, 2- mix and blend pond, 3- digester, 4- natural pond Gas electric generating apparatus, 5- mixing arrangement, 6- incinerator, 7-SBR nitrogen rejection facility, 8- Sewage Plant activated aeration pond.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention.
A kind of system being applied to changing food waste process as shown in Figure 1, including utensil garbage pre-processing device 1, and with The mix and blend pond 2 that utensil garbage pre-processing device 1 connects, and the digester 3 being connected with mix and blend pond 2, and with digester 3 The mixing arrangement 5 connecting, and the SBR nitrogen rejection facility 7 being connected with mixing arrangement 5, and the Sewage Plant being connected with SBR nitrogen rejection facility 7 Activated aeration pond 8.
It is further preferred that being applied to the system of changing food waste process, also include the marsh gas power generation dress being connected with digester 3 Put 4, mud in digester 3 and the produced biogas of utensil garbage pre-processing device 1 are used for generating electricity, carry out the maximization profit of resource With, and power generation operation mode environmental protection, safety;And it is applied to the system of changing food waste process, also include being connected with mixing arrangement 5 Incinerator 6, the mixed liquor that mixing arrangement 5 is processed carries out filter pressing by pressure filter and becomes after cake, is carried out no using incinerator 5 Public hazards, environmental protection burning disposal.
The system of changing food waste process should be used for, the substrate of utensil garbage pre-processing device 1 is changing food waste and feces, Changing food waste and feces and mud access after carrying out mix and blend that in digester 7, (biologic garbage fermentation produces biogas, carries out sending out Electricity).
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art For member, under the premise without departing from the principles of the invention, some improvement can also be made, these improvement also should be regarded as the present invention's Protection domain.
