Black soldier fly larvae (BSFL) have garnered considerable attention for their efficacy in mitigating waste management challenges. However, their potential in treating antibiotics contaminated chicken manure remains uncertain. This study investigates the physicochemical properties changes and nutrient dynamics during the composting of contaminated-chicken manure using BSFL. The results indicate that BSFL treatment reduces electrical conductivity (by 6.01-58.09 %), organic matter, and dissolved organic carbon content in chicken manure throughout the composting process, while maintaining a more stable pH value (pH ∼ 6.0-8.0). This is attributed to the consumption of organic matter by BSFL and the subsequent promotion of organic acid formation. Additionally, BSFL treatment improves the degree of aromatization of dissolved organic matter (DOM) in chicken manure and increases the proportions of fulvic acid (up to 48.77 %) and humic acid (maximally 14.27 %) within the DOM. The germination index and pot experiments indicated improved compost maturity and plant growth in BSFL-treated composts. Furthermore, BSFL meal demonstrated high protein and essential fatty acid content, highlighting its potential as a protein supplement in animal feed. This study underscores the efficacy of BSFL in enhancing compost quality and nutrient availability, offering a sustainable solution for waste management and animal feed production.
黑水虻幼虫（BSFL）在缓解废物管理挑战方面的功效引起了广泛关注。然而，它们在处理抗生素污染鸡粪方面的潜力尚不确定。本研究调查了使用 BSFL 处理污染鸡粪时理化性质变化和养分动态。结果表明，BSFL 处理在整个堆肥过程中降低了鸡粪的电导率（降低 6.01-58.09%）、有机质和溶解有机碳含量，同时保持了更稳定的 pH 值（pH 值约为 6.0-8.0）。这归因于 BSFL 消耗了有机物质，随后促进了有机酸的形成。此外，BSFL 处理改善了鸡粪中溶解有机物质（DOM）的芳构化程度，并增加了 DOM 中富里酸（高达 48.77%）和腐殖酸（最高 14.27%）的比例。发芽指数和盆栽实验表明，BSFL 处理的堆肥中堆肥成熟度和植物生长得到了改善。此外，BSFL 粉表现出高蛋白和必需脂肪酸含量，这突显了其作为动物饲料蛋白质补充剂的潜力。本研究强调了 BSFL 提高堆肥质量和养分有效性的功效，为废物管理和动物饲料生产提供了可持续的解决方案。
