Diffusion preventing, collecting and clearing method for floating oil pollutants on ocean water surface

Abstract

The invention discloses a diffusion preventing, collecting and clearing method for floating oil pollutants on an ocean water surface. The method comprises the following steps of: forming an oil blocking fence by using inflatable floating bodies on an anticorrosive oleophobic surface, and drawing a rope in the fence to shrink the closed area of the fence to collect floating oil chemicals on the water surface till the floating oil chemicals on the water surface are basically collected cleanly; arranging a permanent oil blocking fence on four sides of an oil drilling (recovery) well; arranging an oil blocking belt with a rope on a steamboat so that a temporary oil blocking fence is immediately arranged when an accident happens to timely enclose the water area around a leakage point and prevent the diffusion of the floating oil pollutants; arranging a shrinkable fence, and collecting the floating oil chemicals on the water surface till basic cleanliness; and arranging a last oil blocking fence carrying a photocatalyst and a degradable enzyme so that the residual floating oil pollutants are naturally cleared in a small range. The method can effectively prevent and greatly reduce the diffusion and the residual number of the floating oil pollutants on the wide water surface. The method is simple in operation, low in cost and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of environmental protection of vast water surfaces such as oceans, in particular to a method for preventing the diffusion, collection and removal of floating oil chemical pollutants on the ocean water surface. Background technique [0002] The known method of collecting oil slicks on vast water surfaces such as oceans has only the method of collecting oil slicks on ocean water surfaces. It is to throw hair, fur, etc. into polluted waters, and utilize the lipophilicity of hairs to absorb oil slicks; The best way to remove oil-like chemical pollutants from a wide water surface is to sprinkle (sprinkle) photocatalysts and inoculate microorganisms that can decompose oil-like chemical pollutants to the polluted water surface area. When oil slick pollutants are produced in large quantities (such as oil spills from tankers) or continuously (such as oil spills from offshore oil production wells), the former absorpti...

Problems solved by technology

[0003] In order to overcome the limitations of existing technologies that cannot collect and utilize oil slick pollutants leaked on wide water surfaces such as the ocean and limit the spread of oil slick pollutants themselves and microorganisms used to decompose and remove pollutants, better solve the increasing problems caused by The prevention of diffusion, collection and utilization, degradation, decomposition and removal of oil slick pollutants on the vast water surface caused by accidents such as water transportation and mining, etc. The present invention provides a method for preventing the diffusion, collection and removal of oil slick pollutants on the water surface. It can prevent the spread of oil slick pollutants on the vast water surface, and can collect and reuse the oil slicks. At the same time, it can also prevent the spread of the pollutants themselves and the products after treatment, and limit the scope of pollution and pollution removal until the pollutants are removed. It is basically collected and the residual part is completely degraded and decomposed. At the same time, it can avoid the re-pollution and the spread of re-pollution caused by the decontamination process, and greatly improve the quality and efficiency of the removal of chemical pollutants such as floating oil on the water surface.
