Description

A kind of organic waste dry-type anaerobic high temperature fermentation system and zymotechnique
Technical field
The present invention relates to processing technology field like organic wastes such as the organic moiety in the domestic refuse, rubbish from cooking, greening rubbish, agricultural crop straw, feces of livestock and poultry, septic tank bed mud, active sludge and Herba Eichhorniae, blue-green algaes.
Background technology
At present, the organic composition in China's domestic refuse is in continuous increase.Organic composition in China's domestic refuse is compared with developed countries, and very big difference is arranged, and the content of its paper is lower; The content of rubbish from cooking, greening rubbish etc. is higher; And the water ratio of rubbish from cooking is higher, and general water ratio is 70%~80%, and the water ratio of melon skin etc. can be up to more than 95%.Burn away the refuse to have and reclaim heat energy and waste reduction advantage the most completely, burn afterwards that the rubbish volume can reduce 80%~95%, yet organic waste moisture is high; Net thermal value is low; Suitable the burning, and burn easy " dioxin " type material that produces, cause serious environmental to pollute.Directly landfill waste can produce a large amount of landfill percolates again, handles the bad very easily polluted underground water and the surface water, and percolate is formed complicacy because of it, and concentration is high, and the cost of processing is also very big.Adopt the composting mode treating refuse, can make rubbish become fertilizer, but the fertilizer efficiency of this garbage tankage is low, sell limitedly, room for development is little.
Containing a large amount of moisture, glucide, fat and protein etc. in the organism, is the basic substance of carrying out a biological disposal upon.Anaerobically fermenting is that organism under anaerobic is consumed through the Metabolic activity of mikrobe, and the while is with the generation of methane and carbonic acid gas etc.Anaerobically fermenting is recycled biogas easily because of producing, so claim biogas fermentation again.Do not need oxygen supply in the anaerobic treatment process; Power consumption is low; The organism major part changes biogas into and can be used as bioenergy, and the innoxious degree of fermentation residue raffinate is good, and parasitic ovum and pathogenic micro-organism can be killed during the fermentation; Can become the higher fertilizer of fertilizer efficiency behind the organic matter fermentation, can also be made into novel biomass fuel with mud simultaneously---rod RDF.So anaerobically fermenting often is used as in the research of the ecological agriculture and practice and sets up that an important step is used in the benign cycle agroecosystem, receives increasing concern.
