A scale-down experimental device for simulating the impact of oil spill weathering on water quality

Abstract

An experimental device for simulating the impact of oil spill weathering on water quality in scale. Including: oil spill weathering simulation device, oil and dispersant metering and adding module, water quality sampling and analysis module, aiming at oil spill volume, water surface oil film, water depth, water flow and waves, natural light and other weathering conditions, oil spill weathering and dispersed water quality concentration Changes and other influencing factors, reproduce the impact of oil spill weathering (including oil spill dispersion) on water quality in the scaled-down simulation environment, and restore and convert the experimental results of specific oil products and scaled-down simulation environmental conditions to similar oil spills in the real environment Phase-wise variation in concentration of water quality indicators caused by weathering. The invention provides experimental technical support for scientifically understanding oil spill and its dispersed environmental fate and hazards, carrying out oil spill environmental impact assessment and environmental risk assessment, and actively and effectively taking pollution prevention, emergency response, and environmental restoration countermeasures.

Description

technical field [0001] The invention relates to an experimental device for reducing-scale simulation of oil spill weathering and water quality influence, which belongs to the technical field of environmental protection, oil spill emergency and environmental impact experiments, and can reproduce oil spill weathering (including oil spill dispersion) in a reduced-scale simulation environment The impact on water quality, and restore and convert the experimental results of specific oil products and scaled-down simulation environmental conditions into the concentration fluctuations of water quality indicators in stages caused by similar oil spills in the real environment weathering, so as to scientifically understand oil spills and their dispersion. Environmental fate and hazards after oil spills, carry out oil spill environmental impact assessment and environmental risk assessment, actively and effectively take pollution prevention, emergency response, and environmental restoration ...
