Description
Technical field
The present invention relates to process the Apparatus and method for of organic waste, particularly a kind of Apparatus and method for that changing food waste is changed into fertilizer.
Background technology
Changing food waste and resident living are closely-related, and we will have a meal every day, have a meal and will abandon refuse more or less, and these refuses are exactly changing food waste, claim again swill.Along with industrial develop rapidly, the increase of world population, changing food waste is to the mankind's harm and the emphasis that the pollution of environment more and more caused to people.
China is the country that world population is maximum, and 1,300,000,000 people produce changing food waste every day up to 130,000 tons more than, and according to statistics, there be nearly 3,500,000 of hotel, restaurant in China at present, and the changing food waste quantity that produce every day is very surprising.According to < < Domestic Waste In Beijing in 2004, administer in white paper > > and point out, Beijing " approximately 1050 tons of daily output changing food wastes ".White paper also predicts, by 2008, Beijing's daily output changing food waste will reach 1200 tons of left and right.Another Shanghai, big city of China, daily output changing food waste also approaches 1000 tons.This has also reflected from another one side that the waste of China on dining table is very surprising.Changing food waste has become can affect our important factor healthy and surrounding environment safety, takes the generation of efficient manner management and control changing food waste, and rationally safe disposal changing food waste, very urgent.On the one hand, because changing food waste water ratio is high, difficult problem is collected and transported to ubiquity, if mixed with common domestic refuse, also the water ratio that has improved common rubbish, has reduced calorific value, for the application of garbage incineration technology, has just produced certain difficulty; On the other hand, the organic content in changing food waste is high, and microorganism, bacterium amount reproduction are easy to rot, produce stink under hot conditions, especially rotten in easy fermentation of storage stage and recovery haulage stage temporarily, distributes unpleasant odor, contaminate environment; In addition " rubbish pig " and " sewer oil " that, changing food waste brings are more and more heavier to the mankind's healthy effect.
At present, the common method of processing meal kitchen organic waste has " burying method ", " burning method " and " focusing on the feed chemical fertilizer method of producing " and " microorganism killing method ", and still, these methods are processed organism changing food waste all weak point.
Wherein, the process of " burying method " is: collect transportation, landfill, its shortcoming is to pollute domestic environment in the process of collecting and transporting, and grows mosquito fly phenomenon, after being landfilled, also easily permeate and then polluted underground water, take a large amount of soils simultaneously and produce the problem of secondary pollution.
" burning method " is first with incinerator, to burn away the refuse, with landfill method, process the residue that it produces again, when its shortcoming is burning, because incomplete combustion can produce obnoxious flavour-Dioxins, and landfill incineration residue can produce secondary pollution---soil pollution, particularly, burn and contain very juicy changing food waste and need auxiliary combustion equipment, make incinerator equipment very huge, standing charges are very expensive.
" focus on produce feed chemical fertilizer method " is heating, is uniformly mixed and utilizes the composting mode of microorganism fermentation, its shortcoming to be, the compost of generation, due to reasons such as its ripening degree, quality and component ratios, can not be immediately for the fertilising in farmland; In addition, owing to processing, required time is very long, and the standing charges of collection, carrying, placement and compost, storage are high, and the problem of the health aspects such as stench, corruption is not well solved yet.At present, the time of every batch of changing food waste of the method processing is longer, is generally 2-3 month, and the operation cost of equipment is high.
For example, CN101058098 discloses a kind of swill rubbish dry recovery method, and the method adopts dry, wet tripping device utilizes the weight of changing food waste self to realize the part of changing food waste separated; By centrifugal drying device, realizing moderate dewaters; Collection realizes dry type and deposits; Packing and transporting.Although the method has been sloughed the moisture in changing food waste, can reduce the pressure and the generation of avoiding secondary pollution of terminal process, still need to be transported to destructor plant burning or environment-friendly fertilizer factory and process to obtain organic fertilizer and recycle.
And for example, a kind of apparatus for disposing of food waste is disclosed in CN101199969A, this equipment is to utilize microorganism fermentation to decompose the remaining organic waste in kitchen, and rubbish from cooking can be intersected mobile and mixes with microorganism and carry out pulverization process along fore-and-aft direction, to improve the activation degree of microorganism.
