Description
Technical field
The invention belongs to oil clean technologies field, and in particular to a kind of environment-friendly type is used for the detersive for removing slick
And preparation method thereof.
Background technology
The exploitation of submarine oil starts from early 20th century, but only finds a small amount of offshore oil field within suitable long-term, until
The exploration and exploitation of later stage sixties offshore oil just obtain the development advanced by leaps and bounds.Present existing more than 100 countries in the whole world
Oil-gas exploration is carried out in coastal waters with area, more than 40 countries and regions are exploited in more than 150 offshore oil and gas fields, Crude Oil at Sea
Yield increases day by day, and the daily output more than 1,000,000 tons, accounts for the 1/4 of world oil total output.
Oil and its refined product, such as gasoline, kerosene, diesel oil, easily enter during exploitation, refining, storing and use
The pollution for entering marine environment and causing, is a kind of current global serious marine pollution.
The oil film that oil is formed on sea can hinder the gas exchanges between air and seawater, have impact on sea to electromagnetism spoke
Absorption, transmission and the reflection penetrated.The long-term oil film for being covered in polar region ice face, can strengthen ice cube heat absorption capacity, accelerate ice sheet to melt,
Potential impact is caused to global sea change and longer term climatic change.Oil pollution can destroy seabeach scenic spot and beach bath
.Such as December nineteen eighty-three, " east ambassador " number oil tanker hits a submerged reef stranded, more than 3000 tons of oil spilling, serious ground contamination in Jiaozhou Bay of Qingdao
Qingdao beach and Jiaozhou Bay.
Oil film also reduces the energy that solar radiation penetrates seawater, influences the photosynthesis of sea-plant.Meanwhile, oil film is stained with
The fur and seabird feather of dirty sea beast, dissolve lipid phase therein, and the ability for making them lose insulation, swimming or flight is done
Disturb the ability such as chemotaxis of the ingesting, breed, growing of biology, behavior and biology.Also resulted in by the marine site of oil severe contamination
Individual organisms wealth of species and the change of distribution, so as to change the species composition of group.
The oil slick clean method used at present mainly uses Physical, its shortcoming be Physical cleaning by stormy waves and
The influence of the factors such as viscosity is very big.And the product of the peace and quiet oil of chemical method is used on the market, although it is better than in terms of clean-up performance
Physical, but secondary pollution is easily caused to ocean, or even marine ecology balance can be destroyed, therefore, how to overcome existing skill
