(TS>20%), reducing hydraulic loading and increasing
volume organic loading.
At present, there are few researches and reports on
semi-dry fermentation organic loading of swine manure at
abroad. Moreover, most of the existing researches are
concentrated on batch fermentation process of mixture
material [5-6]. Due to the bottlenecks [7] on the reactor
leakproofness and rapid material loading & discharging
during batch fermentation process, as well as the simplicity
of biogas engineering materials in domestic market, cofermentation
is not suitable for domestic piggery wastes
treatment [8]. The research adopted DPAR to reveal the
yielding gas process by taking swine manure as the material.
The research results demonstrate that swine manure
continuous fermentation process is feasible [9]. However,
there is no research on volume organic loading on biogas
yields from continuous semi-dry fermentation of swine
manure at present. Consequently, to study the yielding gas
process from continuous semi-dry fermentation of swine
manure at different volumes, and to detect the optimal
volume organic loading for semi-dry fermentation of swine
manure have important significance on improving the
utilization rate of dry fermentation device and continuous
dry fermentation performance.
