以猪粪为例,通过加入腐熟剂发酵与自然发酵对比,探讨了畜禽粪便好氧发酵堆肥腐熟度的判定指标。实验表明,松散度、感官气味、温度、pH值、含水量、铵态氮、碳氮比、蛋白酶活性、大肠杆菌数、蛔虫卵死亡率、种子发芽率等可作为判定畜禽粪便腐熟度的指标,另外,重金属和抗生素也应作为重要指标进行检测,随着研究的深入还应从生物学、物理学、生物化学等方面综合判断。
Taking pig manure as an example, compared with the natural fermentation by adding the maturity agent, the determination index of the maturity of aerobic fermentation compost of livestock and poultry manure was discussed. The results showed that the degree of looseness, sensory odor, temperature, pH value, water content, ammonium nitrogen, C / N ratio, protease activity, E. coli count, ascaris egg death rate and seed germination rate could be used to judge the maturity of livestock manure Indicators, in addition, heavy metals and antibiotics should also be tested as an important indicator, with further research should be from biology, physics, biochemistry and other aspects of comprehensive judgment.
