Background technology
Biogas technology has the developing history of last 100 years in China, everybody generally believes that biogas technology is processing organic waste
One of object, environmental protection, most economical, most efficient method for turning waste into wealth, so biogas technology has obtained extensively should in China
With, but in the long-term use, it is found that biogas technology still has a critical defect：Handle highly filled or other difficulties
It is a space without any shelter in the methane-generating pit of the organic liquid waste of degradation, is not provided in pond for biogas bacterium attachment life
Gu fixation the inert media ----bacterium bed of long breeding.Since there are this defects, cause to have in biogas production process and much ask
Topic is difficult to solve, and production rate of methane is difficult to improve always：
1. the mean concentration of fermentation is small
Fermentation raw material is divided into sediment layer, active layer, supernatant layer, scum layer naturally.The material concentration phase of sediment layer, scum layer
To larger, the material concentration of active layer takes second place, and the material concentration of supernatant layer is minimum.Usually our described suitable fermentation concentration are
Average fermentation concentration in entire methane-generating pit is not the optimum concentration of biogas bacterium production biogas, actually biogas bacterium production natural pond
The optimum concentration of gas is bigger than the suitable fermentation concentration usually described in us.Although stirring power breaks raw material layering, raw material is allowed
Be uniformly distributed in pond with strain, increase the contact surface of raw material and strain, but due to stirring difficulty it is big, it is costly, be out of order

It sinks to bottom of pond or floats to feed liquid surface layer and form crust.A part could not be absorbed and utilized by biogas bacterium and just be discharged in fermentation raw material
Outside pond, formed " short circuit " of raw material；A part is accumulated in bottom of pond and forms sediment, forms " blocking ", " open circuit " of raw material；Also one
Fraction floats are on the top of methane-generating pit, and slowly water shortage, drying shrinkage, crust until being formed.When raw material is unevenly distributed in pond, stops
Between the uneven utilization rate and utilization rate of tank volume for largely reducing fermentation raw material, the ferment effect for discharging biogas slurry is also difficult
To ensure.
3. biogas strain quantity is few, it is low to bear organic loading ability
Due to not consolidating bacterium bed, biogas strain exists with suspension, and survival and reproduction space of the biogas strain in pond be not solid
Determine, be unevenly distributed and easily rise with discharging or volatile acid content and be lost in, cause biogas strain quantity few, bear organic
Load-bearing capacity is low.
