摘要

摘要: 为探究液态粪污发酵过程中理化指标的变化和微生物群落结构的演替特征,采用好氧发酵方法,奶牛液态粪污稀释后添加益生菌液(effective microorganisms,EM)和有机肥发酵菌剂(organic fermentation bacteria,OFB)进行发酵。分析发酵过程中COD、氮和磷的变化规律,以种子发芽指数作为腐熟度指标考察液态粪污腐熟程度,探明发酵过程细菌群落的结构特征。结果表明:添加微生物复合菌剂均可以有效降解有机物,粪污稀释为低浓度(low,L)后能更快进入腐熟阶段。其中L-OFB处理在发酵结束时种子发芽指数(GI)达到84.01%,达到完全腐熟。采用高通量测序对Alpha多样性、物种差异分析发现,发酵过程中主要优势菌门为变形菌门、拟杆菌门和厚壁菌门;在发酵周期内,添加EM、OFB菌剂处理的样品中ML635J-40 aquatic group属、Truepera属、Aquamicrobium属、Anaerovorax属、Pseudomonas属的相对丰度较对照处理(CK)处理中更高;冗余分析结果表示,TN是第1影响因子,与细菌群落组成变化显著相关(P<0.05);GI与Aquamicrobium属的相关性最强,在发酵结束时相对丰度较大,可作为腐熟期指示微生物。研究可为今后液态粪污处理工艺的优化提供理论依据。

Abstract: To study the changes in physical and chemical indices and the succession characteristics of the microbial community structure in the process of manure fermentation, using the aerobic fermentation method, commercial microbial compounds including effective microorganisms(EM) and organic fermentation bacteria(OFB), were added for fermentation after dilution of dairy manure. Changes in COD, nitrogen and phosphorus during the fermentation process were analysed. The seed germination index was used as a maturity index to investigate the maturity of the liquid manure, and the structural characteristics of the bacterial community in the fermentation process were studied. The results showed that the addition of microbial compounds can effectively break down organic matter, and the liquid manure can reach the maturity stage more quickly after diluting to low (L) concentrations. The seed germination index of the L-OFB treatment reached 84.01% at the end of fermentation, indicating full maturity. Alpha diversity and species difference analysis using high-throughput sequencing showed that the main dominant phyla in the fermentation process were Proteobacteria, Bacteroidetes and Firmicutes. During the fermentation period, the relative abundance of the ML635J-40 aquatic group, Truepera, Aquamicrobium, Anaerovorax and Pseudomonas was higher in the samples treated with EM and OFB than in the control. The results of the redundancy analysis showed that total nitrogen was the prime factor significantly correlated with the change in bacterial community composition (P<0.05). The correlation between seed germination index and Aquamicrobium was the strongest, and the relative abundance was high at the end of fermentation, which could be used as an indicator microorganism of maturity. This study can provide a theoretical basis for future optimisation of the liquid manure treatment process.
