Processing technique for efficiently removing ocean oil spill

Abstract

The invention discloses a processing technique for efficiently removing ocean oil spill. The technical solution of the invention is as follows: the processing technique for efficiently removing the ocean oil spill comprises the following steps of: (1) air-drying and screening sediments of the muddy sand beach taken from the entrance of the Dagu River to obtain particulate matters with particle size of not more than 35.5 mu m; (2) sorting to obtain the separated particulate matters with particle size of 6-10 mu m; (3) mixing the right amount of particulate matters with sea water, preparing a particle solution of 200-1000 mg / L, and filling the solution in a can to store; and (4) according to the oil spill quantity in the sea water, selecting the particle solution with proper concentration, spraying the particle solution on the surface layer of the oil spill, and stirring the solution through a propeller of a cleaning vessel until the oil spill is fully removed. The processing technique for efficiently removing the ocean oil spill has the following beneficial effects that: (1) by adopting the particulate matters made of natural sediments, the ocean oil spill is removed, toxicity and pollution are free, and interference to the original ecological system after using is less; (2) the processing technique has very high removing efficiency on the oil spill with low concentration; and (3) as the particulate matters have sufficient sources, the particulate matters need not be recycled after using, and further, the cost is low.

Description

technical field [0001] The present invention provides a process that can be used to clean up marine oil spills. Background technique [0002] At present, the main methods to deal with marine oil spill pollution are physical method, chemical method, biological method and incineration method. The physical method mainly includes the deployment of oil booms in the oil spilled waters to prevent the spread of oil spills, and the organization of cleaning ships to remove the spilled oil by mechanical recovery such as oil skimmers and adsorption of absorbent felts and other physical methods. The deployment of oil booms can also be combined with incineration for treatment. The chemical treatment method is mainly to spray oil dispersants, oil collectors and curing agents and other chemicals into the water to disperse or solidify the spilled oil before treatment. The biological method mainly uses the degradation of microorganisms to remove oil spills, including adding nutrients and ad...

Problems solved by technology

[0003] However, these methods have certain limitations. For example, oil slicks of a certain thickness can be recovered by the deployment of oil booms and mechanical recovery methods, but the cost is high, and they cannot be fully utilized due to the influence of weather and ocean hydrodynamic conditions. effect, and the removal of oil spills is not thorough enough

For the adsorption method, the commonly used synthetic organic adsorption materials are costly, difficult to recover and treat after oil absorption, difficult to degrade, and easy to cause secondary pollution if handled improperly; some natural organic and inorganic mineral oil absorption materials have a wide range of sources, but the oil absorption rate is relatively low , It is difficult to operate and control

Incineration is affected by weather and ocean hydrodynamic conditions and can cause significant air pollution

For chemical methods, oil collectors and curing agents are expensive, have a short period of action, and still need to be supplemented by means of mechanical recovery; chemical dispersants are usually toxic to marine organisms and cause secondary pollution to the environment

Generally speaking, bioremediation is more suitable for low-concentration oil spill pollution, but the repair time is long, and the repair effect is greatly affected by complex ocean dynamic conditions, and the highly efficient genetically engineered bacteria cultivated by genetic engineering may have a negative impact on the environment. to bad effects
