摘要
本研究建立了一个用于生物能源生产的连续厌氧两级试验工厂,由 5 个主要设备组成:混合罐、一级厌氧消化器 (AD)、二级厌氧消化器、沉淀池、曝气池和最终沉淀池,所有设备均在环境条件下运行。连续厌氧两级试验工厂的运行由可编程逻辑控制器(PLC)自动控制,采用设计的控制逻辑概念来设定水力停留时间(HRT)和入口基质浓度。分别使用不同的基质:大豆残渣(SR)和食物垃圾水解物(FWH),研究了有机物负载率、水解压力预处理和微生物群落分析对沼气生产性能的影响。研究发现,在 COD 浓度为 3.56 kg m-³-d- 的 OLR 和 11 天的 HRT 条件下,食物垃圾水解物在预处理水解压力为 10 kg cm- 时的沼气生产率峰值为 1.20 m³-m-³-d-,添加 VS 时的沼气产量为 760 dm³-kg-。在第一级厌氧消化器中发现了大量的藻类,大约是第二级厌氧消化器的 6.7 倍。对连续厌氧两级试验工厂进行了适当考察,以确定其在处理食物垃圾和大豆残渣方面的应用,目的是获得可再生生物能源。
Biogas production performance using soybean residue and hydrothermal pretreated food waste hydrolysate in a continuously anaerobic two-stage pilot plant
In this study, a continuously anaerobic two-stage pilot plant was established for bioenergy production, comprising 5 major pieces of equipment: a mixing tank, 1st anaerobic digester (AD), 2nd AD, sediment tank, aeration tank, and final sediment tank, all operating at ambient conditions. The operation of the continuously anaerobic two-stage pilot plant was automatically controlled by a programmable logic controller (PLC) using a designed control logic concept to set the hydraulic retention time (HRT) and inlet substrate concentration. The organic loading rate, pretreatment of hydrolysis pressure, and microbial community analysis were investigated for their effects on biogas production performance using different substrates: soybean residue (SR) and food waste hydrolysate (FWH), respectively. It was found that the peaks of biogas production rate on daily volumetric feeding were 1.20 m³·m⁻³·d⁻1, and the biogas yield on VS added was 760 dm³·kg⁻1 from food waste hydrolysate with a pretreatment hydrolysis pressure of 10 kg cm⁻2, at an OLR in COD concentration of 3.56 kg m⁻³·d⁻1, and an HRT of 11 days, respectively. The Methanobrevibacter genus was found to be abundant in the 1st AD, approximately 6.7 times more abundant than in the 2nd AD. The continuous anaerobic two-stage pilot plant was properly examined for its application in treating food waste and soybean residue with the goal of obtaining renewable bioenergy.
期刊介绍:
Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials.
The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy.
Key areas covered by the journal:
• Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation.
• Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal.
• Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes
• Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation
• Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
