Scaling and simulating experiment device for influences of spilled oil weathering on water quality

Abstract

The invention discloses a scaling and simulating experiment device for influences of spilled oil weathering on water quality. The experiment device comprises a spilled oil weathering simulating device, an oil product and dispersing agent metering and adding module and a water quality sampling and analyzing module; for the influence factors such as weathering conditions such as spilled oil quantity, water surface oil films, water depth, waterflow, waves and natural lighting, spilled oil weathering and dispersed water quality concentration changes, the influences of spilled oil weathering (including spilled oil dispersion) on the water quality reappear in a scaling and simulating environment, and specific oil products and an experiment result under the condition of the scaling and simulating environment are reduced and converted into staged water quality index concentration variation amplitudes, caused by weathering in a real environment, of similar spilled oil. According to the experiment device, experimental technique support is supplied for scientifically understanding spilled oil and environmental fate and harm after the spilled oil is dispersed, performing spilled oil environment impact assessment and environment risk assessment, actively and effectively taking counter measures of pollution prevention, emergency disposal and environment modification.

Description

Technical field [0001] The invention relates to an experimental device for scale-down simulation of oil spill weathering and water quality impact, belonging to the technical field of environmental protection and oil spill emergency and environmental impact experiments. It can reproduce oil spill weathering (including oil spill dispersion) in a scale-down simulation environment The impact on water quality, and the reduction and conversion of the experimental results under specific oil products and scaled-down simulation environment conditions into the phased water quality index concentration changes caused by similar oil spills in the real environment weathering, in order to scientifically understand oil spills and their dispersion After the environmental fate and hazards, carry out oil spill environmental impact assessment and environmental risk assessment, actively and effectively adopt pollution prevention, emergency treatment, and environmental remediation measures to provide ...
