Description
Technical field
The invention belongs to the organic matter anaerobic fermentation process field in environmental treatment, and in particular to a kind of excrement and food rubbish
Rubbish processing meanss.
Background technology
Food refuse（Rubbish from cooking, changing food waste）, excrement（Cultivation excrement, human faecal mass）It is the mankind in organic matter discarded object
One of pollutant being often difficult to avoid that during productive life, deals with improperly and very easily the living environment of the mankind is caused
Greatly pollution or destruction.The mode for processing organic matter discarded object at this stage mainly has landfill, burning, cracking and anaerobic fermentation.
Wherein, landfill disposal is the most convenient, and cost is also minimum, but can cause serious environmental pollution and environmental disruption, after landfill
Organic matter discarded object easily forms the secondary pollution such as percolate or environmental disruption gas, and can ecological environment be caused to grow
Phase, lasting impact, are unfavorable for the protection and sustainable development of ecological environment.Burning disposal has mainly for moisture content is relatively low
Machine matter discarded object, the subject matter that presently, there are have that early stage dehydration is difficult, burning facility floor space is big, energy consumption and processing cost
Height, the energy for burning release are difficult to the problems such as reclaiming, and are difficult in the recent period continue development.Cracking is a kind of novel process mode, can
Most of organic matters in organic matter discarded object are generated the organic matters such as the energy substance that can be utilized by cracking reaction, but
Many insoluble technical barriers are yet suffered from present, and the such as requirement in cracking process to temperature, pressure is higher, equipment corrosion
Depreciation is serious, lysis efficiency is low, not yet find cracking reaction effective catalyst the problems such as.
There is addressing difficulty, high energy consumption, invest big etc. asking in the organic matter offal treatment modes such as landfill, burning, cracking
Topic, large-scale application are extremely restricted.Compare process described above mode, the anaerobic fermentation of organic matter discarded object
Processing carries out resolution process by fermentable to organic matter discarded object, and energy consumption is relatively low, can return after the completion of fermentation reaction
The clean energy resource that transmitting-receiving ferment is obtained, farthest reduces pollutant volume, and can kill organic matter during the fermentation
Pathogen microorganism and parasite in discarded object, has great advantage in terms of environmental treatment.
The decomposition that anaerobic fermentation mainly completes to organic matter discarded object by the enzymatic reaction of microorganism, is reacted by which
Particularity limit, requirement of this processing method to raw material be very high, is only best suitable for the original of anaerobe breeding and metabolism
Material environment just can guarantee that the efficiency of anaerobic fermentation.
Due to organic matter discarded object often wide material sources and composition is sufficiently complex, wherein may be unfavorable for fermenting comprising part
The composition and the inorganic constituents without reactivity of reaction and microbial metabolism breeding, spy is to be processed in industrialization on a large scale
Cheng Zhong, food refuse, cultivation excrement are two raw material sources important greatly.These organic wastes hold in life and production process
The impurity such as many sandstones, paper is easily mixed into.Sandstone is easily in anaerobic reaction-pot bottom deposit, abrasion pipeline, pump etc.；Paper etc. floats
Float is easily enriched with the liquid surface of anaerobic reaction-pot, is affected gas to discharge, is blocked pipeline.Therefore it is reacted in anaerobic fermentation
Front particularly important to raw material desanding removal of impurities.
