摘要
超高温堆肥是近年出现的一种新技术,能够加速有机物分解,缩短堆肥腐熟时间。综述了超高温堆肥工艺方法的优缺点,总结了超高温堆肥在资源化和无害化方面的研究进展,表现在提高了难降解有机物的降解率和总氮的保留率,改善了传统堆肥中抗生素抗性基因难降解的问题,对重金属有一定的钝化效果;论述了超高温堆肥现有研究中的不足,并提出相关建议,旨在优化超高温堆肥工艺,为实际应用提供理论指导。
Hyperthermophilic composting is a new technology in recent years,which can accelerate the decomposition of organic matter and shorten the decomposition time.The advantages and disadvantages of the hyperthermophilic composting process were reviewed in this paper.In addition,research progress on hyperthermophilic composting and its resource and harmlessness were summarized,in which enhanced the degradation rate of organic matter and the nitrogen retention rate,improved the problem of low degradation of antibiotic resistance genes,and passivated heavy metals in certain extent.The shortcomings existed in the current research were discussed and advices were given,which aimed at optimizing the hyperthermophilic composting process and providing theoretical guidance of practical application.
