What is the method to clean up the oil spill at sea

If the clean-up crew arrives at the scene within an hour or two, then the containment of the oil slick and the spill can be used to clean up. That is, the oil spill is enclosed with a long buoyant fence and a skirt that goes deep into the water to prevent further spread of contamination.

At this point, the clean-up vessel can easily suck the oil spill from the surface of the water into the storage. In addition, there is the adsorbent method, in which a huge sponge is used to adsorb the oil spill, and then the oil is incinerated using on-site combustion technology. However, the disadvantage of this method is that it produces air pollution, so it is not likely to be used to clean up oil spills near the coast.

The above method is suitable for oil spill accidents with smooth traffic and far away from the city. In many cases, however, the situation is much more complex, and the site is often dirty, dangerous, and accompanied by air pollution. Oil spills can float to shore and threaten wildlife.

Oil spills on the sea surface are generally handled by a combination of professional companies, using specialized equipment and materials, and a variety of methods.

1. After the oil spill occurs, the oil spill should be contained as soon as possible to prevent the spread. It mainly uses various types of oil boom control. If there is an oil spill on the water surface, depending on the site conditions, solid float type rubber oil boom, solid float type PVC oil boom, rubber inflatable oil boom, PVC inflatable oil boom, fence type oil boom, light inflatable oil boom, flexible fast deployment oil boom, beach and shore oil boom can be used.

If the water flow rate at the oil spill site is large, a fast-flow PVC oil boom can be used to keep the boom erected in the water. In the event of an oil spill from the water surface**, a fireproof oil boom made of heat-resistant steel floats, oil-resistant rubber cloth or PVC high-strength cloth and heat-resistant elements can be used.

2. After the oil spill is controlled in a certain area, according to the thickness of the oil spill, GM-2 oil spill dispersant, oil coagulant, PP-2 linoleum suction felt, oil suction drag bar, combined with different types of skimmers (rope skimmer, turntable skimmer, down belt skimmer, self-propelled skimmer, vacuum skimmer, weir skimmer, turntable brush skimmer), oil spill nets and other different ways. Use floating oil bladders, portable oil storage tanks and other containers to temporarily store and take the oil spill away from the site.

3. If the oil spill area is large, you can also use large-scale equipment such as marine composite skimmer and oil slick ship.

There are many ways to do this, but I'll briefly talk about 1Decomposing ** with a decomposer is very costly, incomplete, and pollutes the environment 2The use of lime to make ** precipitation, more thorough, quite polluting the environment, will harm the seabed life 3

It is collected or burned by fencing, which is suitable for calm seas, and the oil must be very thick.

If you use microorganisms, you can completely eliminate it....It seems to be solved with activated carbon now....

Invent a water-oil separator.

Treatment Methods There are physical, chemical, and biological methods for dealing with offshore oil spills (see). Physical treatment method: such as the use of oil booms, oil-absorbing materials, "oil brooms", vortex sea surface cleaners, etc.

Chemical treatment: such as spraying dispersants, detergents, detergents and other surfactants, etc., to disperse the oil slick on the sea surface into very small particles, so that it can emulsify, disperse, dissolve or settle to the seabed in seawater. Biological Treatment:

For example, the use of microorganisms to remove oil films.

1. Physical removal method: including using a suction machine to absorb oil, scraping oil with a grating and skimmer, and blocking oil diffusion with an oil cable.

2. Chemical closed tomb removal method stove limb: use scavenger or dispersant to decompose ** to form tiny particles that can be dissipated in water.

3. Biological removal method: use microorganisms, such as oleophiles to eat, or use some plants to adsorb.

Marine oil pollution, marine oil spillage accidents or heavy oil spills occur frequently, causing marine pollution and endangering marine life, which has become a major problem of concern in the living world. When oil spills into the sea, it spreads rapidly on the surface of the water and isolates the exchange of oxygen between the seawater and the air. Under the action of wind and waves, some oils can also form oily water with water.

1 liter of oil and water needs to be completely oxidized, and 400,000 liters of oxygen in the water need to be consumed, and many marine organisms are affected by the oxygen in the water"Plunder"While"Suffocation"Die.

Why does a ship leak oil? Most of the oil spills from cargo ships are due to marine accidents.

For example, a ship collision. How to clean up oil pollution, such as natural disasters, shipwrecks, etc.? A leaking freighter can be fenced off to stop it from leaking fuel.

Then use an oil suction ship to suck away the oil pollution at sea.

Also, if the oil washes up on the shore.

then the contaminated sand and gravel should be cleaned up.

According to the past oil spill accidents of oil tankers at sea, the following points are generally inseparable, and the chance of human accidents is very small: 1Hit the rocks.

2.Touching an iceberg by mistake. 3.

Unfortunately, a typhoon caused the oil tanker to capsize, resulting in an oil spill. The Drum Zen method for dealing with oil spills at sea from oil tankers generally takes three main steps to remove the oil slick from the water surface. First of all, use a fence oil cable like a floating fence to enclose the oil film and then use a skimmer to suck the oil away; Then, adding an adsorbent substance (human hair is a good adsorptive substance) to the enclosed oil spill to make the oil adhere to it, which is much easier than cleaning up the oil alone; Thirdly, a dispersant (similar to a liquid cleaner) can be used, but this method is not as satisfactory as the physical removal method, because this method only disperses the oil into the water or water, not removes, but the air dust method is very useful when the liquid preparation prevents the oil slick from reaching the coast and causing greater harm, but some environmental experts say that although this method can solve one environmental pollution problem, on the other hand, it creates another environmental pollution problem. Reference:

When the ship leaks oil in the open sea, due to the strong wind and waves, it is difficult to deal with it, so it is difficult to take the best measures, and the damage can only be blocked. The oil that has been leaked can only be left to its course.

If there is an oil spill offshore or in a port, the following measures are generally taken: First, there are special rescue vessels carrying oil barrages made of rubber to intercept the oil slick. This type of vessel is usually operated by two groups of two, and can be used as a dragnet fishing boat, pulling the two ends of a floating dam separately, encircling the oil in the middle and limiting its continued spread.

The second step is to stretch out the oil pollution ** pipe and pump the oil slick back to the special storage tank on the ship. The end of this ** pipe is equipped with a float, so that the nozzle always floats on the sea surface, and only sucks the oil slick on the sea surface, but does not suck a large amount of seawater. When the oil layer on the sea surface is thick, this kind of oil pollution pipe can play a very high efficiency.

The last step is to use linoleum ** residual oil stains. When the residual oil layer is very thin, the ** pipe is useless (only a large amount of seawater will be pumped up), and then the rescue ship throws a large amount of linoleum similar to white sponge into the water. This linoleum has undergone a special treatment to absorb only oil and not water.

Then the rescue ship salvaged the linoleum. After these treatments, the oil stain is basically cleaned up. The rescue ship can put away the oil dam and return to the sea.

At present, it is only a lot of fur to suck ......

Method 1: Fence the oil slick first If the amount of oil spilled is large, the first step is to fence the oil with a floating fence. Some of these floating fences are inflatable, some are made of lighter than water, and are generally about 1 meter above the water, some "sit" on the waves, and some stretch out 1 meter of "skirts" underwater. Method 2: Physical and chemical method For the oil slick on the water surface, you can use the "oil pumping ship" to separate the oil and water.

Some tankers suck the oil-water mixture into the tanks on board, separate it with centrifuges, and then discharge the water into the sea. You can also use something like a sponge to suck the oil inside, which can be made with chemical fibers, or you can use natural fibers like hair. In order to obtain oil, it is sometimes possible to add an "oil coagulant" to it.

It can change the oil in the water from a liquid state to a semi-solid state, even a solid state like rubber. This kind of object is easy to fish, and it can also prevent the oil from volatilizing benzene, formaldehyde, acetone and other substances into the air. This hardener is relatively less harmful to the environment.

Some curing agent manufacturers claim that the cured petroleum can be reused to produce asphalt or elastomer, or even used as a fuel with very little ash. There is also a way to do the opposite, which does not allow the oil to solidify, but allows them to bind better with water. The "dispersant" breaks the intact oil film of the oil, allowing it to disperse into small droplets in the seawater.

Method 3: Adopt "oil-eating bacteria" At present, the use of bacteria to degrade oil is mainly used to repair small-scale oil spills at sea and oil pollution on land. In the case of large-scale offshore oil spills, the spilled oil is generally collected by physical and chemical methods until there is some oil left that is difficult to collect, and then degraded by microorganisms. **Which product is better As for how long it takes for the oil to be completely degraded, it has a lot to do with environmental conditions, such as the cold and heat of the environment, and the decomposition rate in Alaska and the equator is definitely different.

It is also related to the composition of petroleum, the more heavy oil, the more difficult it is to decompose, and the salt content of seawater is relatively high, and the nutrients are relatively small, so it will be more difficult to decompose. In general, it will certainly not be broken down in a day or two. This rate also has a lot to do with the biomass, activity, and survival time of bacteria.

In short, human beings have "eighteen kinds of weapons" to deal with oil pollution, which is generally difficult to get rid of oil, and at the same time inevitably hurt themselves, so it is best that they never have a chance to be used.
