对于氨气和硫化氢释放量的减少有显著差异, 翻堆间隔 3天的处理在第 7天氨气和硫
化氢的释放量为 76.97%和 63.67%,对于硫化氢的减少量而言,在第 7天时,翻堆间
隔三天和五天并无显著差异,但与间隔七天差异显著。而翻堆间隔时间短会增加工作
量,所以从经济角度看,堆肥开始后前 2 周每 3天翻 1次,之后每 5天翻 1次。

Abstract
With the development of pig industry and people of environmental protection
consciousness, the pig breeding pig improve stench pollution problem has already more
and more prominent, about the deodorization processing pig has become one of the
important production and pollutionfree link.Anhui is the big province in our country for
producing rape, the perennial rape yield in the country, is the second one of the main
production base of rapeseed. The large relative to rape the utilization rate of planting, rape
straw is very low, the burning of the majority, namely environmental pollution and a waste
of resources, So taking pig and rape straw for research object, add microbes in the
deodorization bacterium agent conditions, the pig and rape straw mixed aerobic
composting process temperature, seed germination index (GI), composting process and
organic content the pH, total nitrogen content, ammonia and hydrogen sulphide levels and
other parameters of the change rule, so as to explore the different parameters and the
relationship between composting compost filtrated compost, the optimal parameters of
compost. Compost deodorization of pig has certain directive significance.
The main results were as follows:
、
1 The optimization of fermentation conditions: through the use of single factor
experiments and orthogonal test method, derived microbial deodorant ideal fermentation
conditions 7NC nutrient broth medium: peptone 1
