摘要

研究了生物炭（BC）、零价铁（Fe0）、生物炭负载的零价铁（BC/Fe0）、磷酸铁锂（LiFePO4）和生物炭负载的磷酸铁锂（BC/LiFePO4）对水热处理后的Platanus orientalis Linn （FLPOL）落叶液固混相厌氧消化（AD）过程中甲烷生成的影响。结果表明：在水热固液混相产物AD实验中，最有效的促进剂为Fe0，累计产气量为252.3 mL/g VS， SCOD去除率为95%，甲烷产率为159.9 mL/g VS；在水热液相产物AD实验中，最有效的促进剂为LiFePO₄，累计产气量为104.7 mL/g VS， SCOD去除率为90.9%，累计产甲烷量为64.2 mL/g V。

Effect of Accelerators on Hydrothermal Anaerobic Digestion of Platanus Orientalis Linn Fallen Leaves

The effects of different accelerators—biochar (BC), zero-valent iron (Fe⁰), biochar-loaded zero-valent iron (BC/Fe⁰), lithium iron phosphate (LiFePO₄), and biochar-loaded lithium iron phosphate (BC/LiFePO₄)—on methane production during anaerobic digestion (AD) of the fallen leaves of Platanus orientalis Linn (FLPOL) in both liquid and solid–liquid mixed phases after hydrothermal treatment were investigated. The results showed that in the hydrothermal solid–liquid mixed-phase product AD experiment, the most effective promoter was Fe⁰, with a cumulative gas production of 252.3 mL/g VS, a SCOD removal rate of 95%, and a methane yield of 159.9 mL/g VS; In hydrothermal liquid-phase product AD experiments, the most effective promoter was LiFePO₄, with a cumulative gas production of 104.7 mL/g VS, an SCOD removal rate of 90.9%, and a cumulative methane production of 64.2 mL/g V.

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
