Problems solved by technology

However, there are no good physical and chemical methods to deal with oil spills on the seabed or oil pollution that sinks into seabed sediments with water movement. Environmental self-purification of oil-degrading microorganisms in sediments and artificial introduction of oil-degrading microorganisms are the current solutions. Major modes of oil pollution in marine sediments
[0003] However, the disadvantages of the above-mentioned methods are: 1. Physical and chemical restoration methods can easily cause secondary pollution; Time effect, cannot form long-term effect

Embodiment 1

[0035] A restoration method for marine oil pollution degradation, comprising the following steps:

[0036] (1) Preparation of seed solution

[0037] a. Preparation of medium: Add 10g of tryptone, 5g of yeast extract and 10g of sodium chloride into 950ml of deionized water, shake the container until the solute is dissolved, adjust the pH to 7.0 with 5mol / L NaOH solution, and then set the pH with deionized water. Make up to 1L, steam sterilize at 15psi high pressure for 21min;

[0038] b. Inoculate marine restoration bacteria into the culture medium in step a, and place it on a shaker to cultivate until the absorbance is greater than 1.0, and there is no miscellaneous bacteria in the microscopic examination to prepare the seed liquid;

[0039] (2) Preparation of bacterial liquid

[0040] a, primary fermentation: in the primary fermentation tank, 450g of tryptone, 120g of yeast extract powder, 1.4g of calcium chloride, 14g of magnesium sulfate, 800g of sodium chloride, 4g of fe...

Abstract

The invention belongs to the field of marine pollution degradation, and particularly relates to a repairing method for degrading marine petroleum pollution. After a large number of functional microorganisms are cultivated in a fermental manner, a bacteria solution is adsorbed and fixed on zeolite by using an immobilization technology and is wrapped in a PGA packaging mode to form a microbial agent product, a protecting agent (nutritional agent) wraps the surface of the zeolite, in a settlement process, loss of the microorganisms in apertures of the zeolite is reduced as much as possible, meanwhile, a wrapping agent serves as a nutrient source of the microorganisms, and secondary pollution to water is avoided. The throwing mode is a brand-new throwing line, throwing coverage wide reaches 9 meters, microbial agents are spaced from one another uniformly, throwing efficiency is high, and by the high-quality microbial agents and accurate throwing, the efficient repairing method for degrading marine petroleum pollution is formed.

Description

technical field [0001] The invention belongs to the field of marine pollution degradation, and in particular relates to a restoration method for degradation of marine oil pollution. Background technique [0002] Offshore oil spills and oil pollution have always been important issues affecting the marine environment and marine ecology. At present, the emergency treatment of marine oil pollution, especially sudden oil spill accidents, mainly focuses on the surface seawater in the early stage of oil spill, and adopts physical interception, recovery and other methods for emergency treatment. However, there are no good physical and chemical methods to deal with oil spills on the seabed or oil pollution that sinks into seabed sediments with water movement. Environmental self-purification of oil-degrading microorganisms in sediments and artificial introduction of oil-degrading microorganisms are the current solutions. Major means of oil pollution of marine sediments. [0003] How...
