Globally, bauxite residue is creating extensive environmental problems. Nevertheless, there are numerous functional microorganisms that exist in this extreme environment, and fungus has an essential role the pedogenesis of residue. This study describes a microbial method to reduce alkalinity through actions produce acidic substances. Bauxite samples were screened for fungal activity, tolerance was assessed using saline alkaline media varying concentrations, aniline blue-PDA medium evaluate...
Abstract Ecological reconstruction on bauxite residue (tailings) disposal areas is regarded as an effective approach to eliminate potential environmental risks. Establishment of microbial communities and associated functions may improve physical chemical properties, stimulate soil formation in residue. Spontaneous colonization at a area Shandong Province, China, over 50 years, indicated that natural weathering can ameliorate residues, turn, support the establishment vegetation communities....
The construction of deep foundation pits that are adjacent to an operating subway tunnel can cause significant disturbance the surrounding soil and structure. Assessing stability in security area is key controlling displacement Assuming behind wall elastic stage small deformation, unloading stress distribution law on excavation surface side inversely calculated using horizontal curve retaining Based analytical solutions for settlement proposed this paper, spatial characteristics deformation...
Ecological succession by microbial activity on bauxite residue disposal areas (BRDAs) would accumulate nutrients and convert the into a soil-like material. However, role of microorganisms in nutrient cycling remains elusive BRDAs. Carbon (C), nitrogen (N) phosphorus (P) ecological stoichiometry is critical indicator an ecosystem. In order to investigate changes following long-term natural weathering process, contents C, N, P, biomass carbon (MBC), (MBN), (MBP) were measured chronological...
Abstract Purpose Long-term weathering promotes the development of microbial communities and increased diversity in bauxite residue. However, effect different vegetation cover on stability community are still poorly understood. Methods In this study, residue samples from three typical including Artemisia (BA), Cynodon (BC), Hedysarum (BH) were collected a deposit area. Illumina high-throughput sequencing technology was applied to determine Results Residues vegetated sites exhibited lower...
Aims Phosphorus mining wasteland is a very special kind of degraded ecosystems, where vegetation and land- scape are severely damaged. Our objective was to select plants suitable for phytoremediation phosphorus-rich soils in wasteland. Methods We conducted pot experiments investigate phosphorus uptake accumulation capacity Helian- thus annuus, Sorghum sudanense Cucurbita moschata grown with different levels sup- ply. The concentrations applied 0, 100, 300, 500 700 mg·kg -1 . concentration,...
The simulation of the structure frame a flying car is carried out to verify feasibility design scheme.Based on Patran/Nastran, simulated by finite element method.The mechanical performance under working condition, strength redundancy and deficiency original are analyzed sought in order achieve optimal frame.The optimization results indicate that distribution more reasonable after lightweight design, weight reduced 32.62% compared with design.
