The high concentration organic solids such as rubbish, the expired food of supermarket, food processing discarded object, vinasse, agriculture organic solid castoff are discarded
Thing is not perfect in China due to classification mechanism, and traditional organic waste is generally using landfill, burning or aerobic compost processing mode.
Due to the restriction using soil, landfill is faced with more and more difficult location problem in China；Although burning can obtain compared with
Good reduction, but the higher organic waste of moisture content often greatly increases burning cost；Organic waste compost is at me
One-hundred-year history goes up in state, but it has some row such as odor pollution, product outlet, causes aerobic compost thoroughly to have
Effect solves extensive organic waste and centrally disposes problem.
And anaerobic digestion is produced natural pond technology and organic waste can be turned waste into wealth, its biogas for producing belongs to reproducible biomass
The energy, belongs to the new forms of energy that country encourages the substitute fossil fuels of development, and the epoch of energy scarcity in the world, this point is particularly weighed

In fixed three phase separator easily blocked by high concentration material, UBF fillers also due to blockage problem, need to strictly control into
Material impurity content.CSTR techniques are low compared with other wet type anaerobic digestion process to impurity content requirement, processing moisture content in recent years
More application has been obtained in higher organic materials.
How wet type and dry type anaerobism each advantage is given full play to, and traditional handicraft adopts split-type design, i.e. dry type anaerobism
Jing after dehydration, liquid phase enters back into wet type anaerobic digestion for digestion discharging, and its complex process, floor space are big, and need to arrange middle slow
Deposit and dewatering system, because dry type anaerobism adopts full-mixing type digestion method, containing a large amount of undegradable organic matters in discharging, Jing takes off
After water system, only liquid phase part enters wet type anaerobic digestion, and more undegraded organic matter is still contained in dehydration solid phase.
