【摘要】：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发酵鸡粪原料,可以活化养分,提高实际肥效,并去除鸡粪中的有害生物组分,达到快速腐熟,实现鸡粪的无害化处理。
[Abstract]:This test uses chicken fast fermentation bacteria enzyme thermal thermophilic aerobic fermentation process, thermophilic enzyme fermentation agent to add 1 per thousand, under the temperature of 80 C and 90 C, in the heat of the enzyme reactor rapid fermentation for 8 h, 4 h, 6 h, 8 h respectively to evaluate the sampling quality of chicken manure fermentation effect of chicken manure. The results showed that after fermentation of raw materials with improved appearance, pungent odor significantly reduced; organic matter content had no obvious change, nitrogen phosphorus and potassium concentration increased to 11.02%, compared with the actual effect of chicken manure raw materials increased by 25.8%, increased by 8h; after fermentation, significantly reduced the number of bacteria, fungi, actinomycetes, fecal coliform coli and Ascaris eggs were not detected by enzyme, fermentation technology of heat removal of harmful biological components in chicken manure; chicken manure fermentation samples for germination test, seed germination rate was above 93.33% (89.33% for raw materials, chicken manure) showed that the sample has been decomposed completely. The test results show that. Fermented chicken manure can be rapidly fermented by thermophilic enzyme aerobic fermentation process, which can activate nutrients, improve actual fertilizer efficiency, and remove harmful biological components from chicken manure, so as to achieve rapid maturity and achieve the harmless treatment of chicken manure.

【正文快照】： 1引言家禽规模化养殖为市民提供大量肉类、禽蛋及制品的同时也带来了大量的废弃物——禽粪。中国作为畜禽大国每年会产生大约27亿t畜禽粪便[1],其中鸡粪约有4.1×108t,如何将这些废弃物变废为宝,相关人员进行了大量研究。禽粪的有机质和氮磷钾养分含量都较高,是制作有机肥的上
