Degradation device for offshore oil pollution area

Technical Field

The invention belongs to the technical field of petroleum pollution degradation, and particularly relates to a degradation device for an offshore petroleum pollution area.

Background

Oil pollution refers to pollution caused by leakage and oil discharge during oil exploitation, transportation, loading and unloading, processing and use, and mainly occurs in oceans. The petroleum floats on the sea surface and quickly diffuses to form an oil film, and can be migrated and converted through diffusion, evaporation, dissolution, emulsification, photodegradation, biodegradation, absorption and the like. The oil can adhere to fish gill to suffocate fish, inhibit oviposition and incubation of waterfowl, destroy water impermeability of feather, and reduce aquatic product quality. The formation of the oil film can block the reoxygenation of the water body, influence the growth of marine plankton, destroy the ecological balance of the sea, and in addition, can also destroy the landscape of the seashore and influence the aesthetic value of the seashore. The petroleum pollution prevention and treatment can be carried out through an oil containment boom, an absorption material, an oil eliminating agent and the like besides controlling a pollution source and preventing accidents.

The microorganism is applied to put and degrade the petroleum leakage area in the ocean, and a certain use effect is also obtained. However, because the thrown microorganisms have strong freeness, particularly along with the shaking of seawater, the displacement speed is higher, and the treatment efficiency is also influenced; and the microorganisms may be separated from the petroleum-contaminated area, which further results in a reduction in degradation efficiency.
