| Abstract: |
| The research was carried out in summer of 2011. The dynamic changes o
f basic properties and microbial community during the composting process of shee
p slaughterhouse waste were investigated. And the effects of different microbial
agents that inoculated to the compost process were also discussed. The results
showed that the temperature was increased at the beginning of the process and th
en decreased. The seed germination index and the vigor of weed seed had the incr
easing tendency, while the microbial biomass and eggs of insects had the decreas
ing tendency through the composting process. The pH value increased faster in wa
rming phase (average by 1.75), then leveled off, and decreased slightly to an av
erage of 8.20 at last. Bacterium biomass increased fast from 2.42×108 to 5.16
×108 CFU·g-1 averagely. Actinomycete and fungi increased slowly at the
beginning of the process, then actinomycete and fungi increased significant at
the beginning of the process. bacterium were decreased slump at the moment. The
speed of change that fungi biomass were slowly than actinomycete. Inoculated mic
robial ag
ents could raise the temperature of compost, speed up the rate of fermentation e
ffectively. The results showed that agents of No.4 were best among the microbial
agents studied. |
