摘要
本研究旨在分析生猪屠宰场废弃物高温堆肥过程中其基本性质和微生物特性的动态变化规律,探讨添加不同微生物菌剂对屠宰场废弃物堆肥进程的影响。试验结果表明:屠宰场废弃物堆肥温度、种子发芽指数(GI)、草籽灭活率、卫生指标和微生物数量的变化规律与动物粪便高温堆肥规律基本相同,但所用时间略长,pH在升温阶段大幅度升高,然后持平,最后略有降低。在堆肥过程中,微生物数量总的趋势是细菌的数量最多,放线菌次之,真菌的数量最少。向堆肥中添加微生物菌剂可加快堆肥腐熟,缩短堆肥周期。其中添加微生物菌剂3的堆肥,各项指标变化相对较快,综合判定添加菌剂3的堆肥效果最好。
Dynamic change rule of basic properties and microbial community during the composting process of pig slaughterhouse waste was investigated;discuss the effect of different microbial agent that inoculated to the compost process.The results showed that the change role of temperature,the seed germination index（GI）,the seeds of weeds,the eggs of insects,microbial biomass were similar to the composting of animal manures,only the time is longer than animal manure;pH was increased faster in warming phase,then steady,decreased slightly at last.During the composting process,the most of microorganism count was bacterium,the second was actinomycete and the least was fungi.Inoculated microbial agent could raise the temperature of compost,speed up the rate of fermentation effectively.The results showed that microorganism agents of No.3 was better among the microorganism agents studied.
