摘要:
餐厨垃圾黑水虻转化技术因其周期短、转化效率高、昆虫制品价值潜力大等优点而受到公众重视,但对黑水虻生物转化后的残留物的再处理鲜有报道。结合生化测试和波谱分析,在为期49 d 的残留物条垛式二次堆肥过程中,研究物料的生化特征及其溶解性有机质(Dissolved organic matter,DOM)的动态变化特征。结果表明堆体物料温度在7 d 内快速升至63.8 ℃,之后缓慢降低至结束时的27.7 ℃,物料含水量从初始的65.4%逐步下降至38.6%,处理后物料DOM、速效磷、总氮和铵态氮含量分别降低了69.1%、41.7%、11.8%和22.6%,而硝态氮含量提高了18.7倍。三维荧光光谱、傅里叶变换红外光谱以及核磁共振分析发现:(1)物料DOM组分中酚类、醇类、脂肪、蛋白质、以及乳酸类等物质逐步降解;(2)碳水化合物烷基链烃类物质含量逐渐下降,且链烃支链逐渐变短,烯烃类与芳香组类、多糖类等物质被降解的同时又生成新的同类物质;(3)β-木糖、β-半乳糖和β-阿拉伯糖、α-半乳糖、α-阿拉伯糖以及α-葡萄糖等溶解性单糖相对增加,有机胺、含甲基有机质、以及有强抗病毒功能的肌苷三磷酸类等物质相对增加。随着二次堆肥的进行,物料DOM化学组分多样性增加,其结构复杂性下降,稳定性和芳香性组分相对增加。上述研究表明黑水虻生物转化残留物经二次堆肥后,其腐殖化程度加深,产品质量得到提升。
Abstract:
The bioconversion technology of black solider fly larvae (BSFL) for kitchen waste treatment and reuse has attracted public attention s because of its short cycle, high conversion efficiency and great potential value of bioproducts. However, there are few reports on the reprocessing of the residues after BSFL bioconversion (i.e., vermicompost). In this paper, combined with biochemical test and spectral analysis, the biochemical features of BSFL vermicompost and the dynamic change characteristics of dissolved organic matter (DOM) during 49 days of secondary composting under the strip-stacked operational model were described. The results showed that the temperature of the vermicompost increased rapidly to 63.8 ℃ within 7 days, and then slowly decreased to 27.7 ℃ at the end , meanwhile the moisture content gradually decreased from 65.4% to 38.6%. After treatment, the contents of DOM, available phosphorus, total nitrogen and ammonium nitrogen in vermicompost decreased by 69.1%, 41.7%, 11.8% and 22.6%, respectively, while the content of nitrate nitrogen increased by 18.7 times. Three dimensional fluorescence spectroscopy, Fourier transform infrared spectroscopy and nuclear magnetic resonance analysis showed that: 1) phenols, alcohols, fats, proteins, lactic acids and other substances in DOM of vermicompost were gradually degraded; 2) The content of alkanes and alkanes in carbohydrates decreased gradually, and the branched chain of alkanes became shorter. While the alkenes, aromatics and polysaccharides were degraded over time, new similar substances were formed; 3) The soluble monosaccharides such as β -xylose, β-galactose and β-arabinose, α-galactose, α-arabinose and α-glucose were relatively increased, while organic amines, methyl organic matter and inosine triphosphate with strong antiviral function were relatively increased. With the second ary composting, the diversity of DOM chemical components in vermicompost increased, the complexity of DOM structure decreased, and the stability and aromatic components increased . In summary, the humification degree of DOM in vermicompost was deepened and the bioproduct quality was improved after secondary composting.
