Abstract

The invention relates to the technical field of management of oil polluted environments, in particular to an oleophylic fertilizer for bioremediation and a method for preparing the oleophylic fertilizer. The oleophylic fertilizer is composed of lecithin, oleic acid, nitrogen-phosphorus solution and alcohols. The preparation method includes: mixing the lecithin with the alcohols proportionally, heating, ultrasonically dissolving, adding the nitrogen-phosphorus solution and oleic acid of a certain quantity, and performing vortex oscillating to form water-in-oil microemulsion, so that the product is obtained and sealed for storage. After the oleophylic fertilizer contacts with oil pollutants, the oil pollutants can form fine oil drops to be aggregated, the oleophylic fertilizer is attached onto the oil drops to provide nitrogen and phosphorus source needed by oil degrading microorganisms, and bioremediation effect can be remarkably improved.

Description

1 technical field

[0001] The invention relates to the technical field of oil-polluted environment treatment, in particular to an lipophilic fertilizer for bioremediation and a preparation method thereof. After the fertilizer is in contact with petroleum pollutants, it can make the oil film form fine oil droplets and aggregate, while the lipophilic fertilizer adheres to the periphery of the oil droplets and provides the nitrogen and phosphorus sources required for the growth of petroleum-degrading bacteria, which can significantly improve the bioremediation effect. 2 background technology

[0002] With the rapid development of the petroleum industry, the damage of petroleum to the environment has attracted more and more attention. Especially for the marine environment, various oil spill accidents have caused serious harm to the marine ecosystem and restricted the sustainable development of human society and the environment. The bioremediation technology of oil pollution is c...
