A degradation device for marine oil polluted areas

Abstract

The invention discloses a marine petroleum polluted area degradation device, which comprises a fence, stay ropes, and degradation bags. The tail and head of the fence are connected to enclose a region. Multiple stay ropes are arranged in the region. Two ends of each stay rope are both fixed on the fence. Multiple degradation bags are arranged on each stay rope at equal intervals. The floating type fence can enclose a petroleum polluted area so as to effectively prevent a petroleum layer in the petroleum polluted area from escaping; and at the same time, the impact of sea water out of the polluted area on the petroleum in the polluted area is reduced. The degradation bags are fixed on the stay ropes, the degradation bags will not be lost, moreover, the degradation bags can be evenly distributed in the polluted area, the degradation efficiency is improved; the fence and cell immobilization can reduce the impact of sea water, the falling of degradation bacteria caused by impacting is reduced, and the using time of immobilized cells is prolonged. The structure is simple, the device is user-friendly, the enclosing effect is good, the escape of petroleum layer is effectively prevented, moreover, the degradation bags are evenly distributed, and the degradation efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of petroleum pollution degradation, and in particular relates to a degradation device for marine petroleum pollution areas. Background technique [0002] Oil pollution refers to the pollution caused by leakage and discharge of oil during oil extraction, transportation, loading and unloading, processing and use, mainly in the ocean. Oil floats on the sea surface and rapidly spreads to form an oil film, which can be migrated and transformed through diffusion, evaporation, dissolution, emulsification, photodegradation, biodegradation and absorption. The oil can adhere to the gills of the fish, suffocate the fish, inhibit the spawning and hatching of waterfowl, destroy the impermeability of their feathers, and reduce the quality of aquatic products. The formation of oil film can hinder the reoxygenation of water bodies, affect the growth of marine plankton, and destroy the ecological balance of the ocean. In ad...

Problems solved by technology

[0005] The purpose of the present invention is to provide a degradation device for offshore oil-contaminated areas, which aims to solve the problems in the prior art that the degrading bacteria that are sprinkled are relatively free, and are prone to separation from oil-contaminated areas, resulting in poor degradation effects
