本试验采用嗜热菌酶好氧发酵工艺快速发酵鸡粪,添加1‰的嗜热菌酶发酵剂,温度控制在80℃-90℃,在热酶反应器中快速发酵8 h,在4 h、6 h、8 h分别取样评价其发酵对鸡粪品质的影响.研究结果表明:鸡粪原料经发酵后外观明显改善,刺激性气味明显减少;有机质含量无明显变化,氮磷钾浓度上升至11.02%,较鸡粪原料提升25.8%,实际肥效提高;经8h发酵后,细菌数量明显减少,真菌、放线菌、粪大肠杆菌及蛔虫卵均未检出,说明通过热酶发酵技术去除了鸡粪中的有害生物成分;鸡粪发酵样品进行发芽试验,种子发芽率均在93.33%以上(鸡粪原料为89.33%),表明样品已腐熟完全.从试验结果可以看出,利用嗜热菌酶好氧发酵工艺快速...

The experiment used thermophilic enzymes（1 %cthermophilic enzymes added） and aerobictic fermentation technology to ferment chicken droppings under 80-90 °C ,and the fermentation was carried out in the reactor for 8 hours and sampling was made in 4h, 6h and 8h. The results showed that the appearance of chicken manure was im-proved and pungent smell decreased significantly after fermentation ; Organic matter content had no obvious change while the total content of N, P and K increased to 11.02% ,the content increased 25. 8% compared with the c...
