Oil spill dispersant and preparation method thereof

Abstract

The invention relates to the field of water-polluted environmental remediation and discloses an oil spill dispersant and a preparation method thereof. On the basis of total weight of 100wt%, the oil spill dispersant comprises 2-8wt% of biosurfactant, 4-10wt% of synthetic surfactant, 2-10wt% of inorganic mineral, 2*108-10*108 CFU / mL microorganism spore aqueous solution and the balance of water. Thebiosurfactant is selected from ester and peptide type biosurfactant; the synthetic surfactant is selected from alkyl glycoside and / or fatty alcohol-polyoxyethylene ether; the inorganic mineral is selected from at least one of nitrogenous inorganic mineral salt, phosphorus-containing inorganic mineral salt and potassium-containing inorganic mineral salt; the microorganism spore is selected from the spore formed by the crude oil degrading bacteria for generating spore. The spore is added into the oil spill dispersant disclosed by the invention, so that the microorganism concentration of the oilspill dispersant can be kept stable for a long time, the stress resistance of microorganism can be promoted and the dispersing and degrading effects of oil spill can be improved.

Description

technical field [0001] The invention relates to the technical field of environmental remediation of water body pollution, and more particularly relates to an oil spill dispersant and a preparation method thereof. Background technique [0002] With the acceleration of global economic integration, the development of marine transportation and the development of offshore oil resources, marine oil spill pollution has become more and more serious, and marine oil spill pollution has also attracted more and more attention from all countries in the world. [0003] When a large-scale oil spill accident occurs, a large amount of oil enters the marine environment instantly, and spreads rapidly to form a thick oil layer on the sea surface, causing severe hypoxia in the large area below it, which in turn causes plankton, fish and shrimp Die from lack of oxygen. If the oil pollution is not cleaned up in time, it is very easy to cause explosion and fire, leading to serious consequences. I...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an oil spill dispersant to improve the stress resistance of microorganisms in view of the problem that the existing oil spill dispersant loses all the active microorganisms with the prolongation of the storage period, resulting in a decline in oil spill dispersion and degradation effects , to enhance the effect of offshore oil spill treatment
