黑水虻转化有机废弃物及虫沙资源化利用研究进展OA

The conversion of waste by black soldier fly(BSF)is a maturing resource utilization technology,and the resulting larval frass is a highly valuable organic fertilizer.The biological conversion efficiency(BCE)of BSF can range from 3.75%(cattle manure)to 59.4%(food waste).This paper starts with improving the BCE of BSF and the fertilizer potential of larval frass,and reviews the effects of nutrient supply such as crude protein and crude fat in different substrates,as well as environmental factors such as temperature,humidity,pH,and larval density on larval growth and BCE.It also analyzes the production process,nutrient value,and fertilizer effect of BSF larval frass,explores the synergistic role of microorganisms in the conversion process,and reveals the main problems faced by the BSF waste conversion technology,such as the difficulty in improving quality due to extensive production,ecological challenges in the industrialization of BSF larval frass,and the lack of industry standards.The paper also offers prospects and suggestions from the aspects of stabilizing conversion efficiency,ensuring ecological safety,and leading industrial standardization.It is hoped that this work can provide inspiration for the efficient utilization of organic waste and the development of the BSF conversion industry.
