Abstract

The invention discloses a biological oil spilling dispersing agent which is used for emulsifying spilled oil by a surfactant and performing biological repair quickly by using related microbes when oil spilling accidents occur in the process of oil exploitation, oil transportation and oil storage and a preparation method of the biological oil spilling dispersing agent. When the oil spilling accidents occur, the oil spilling dispersing agent is one of common methods for emergent treatment at present, but the conventional chemical oil spilling dispersing agent product has the defects of more consumption of chemical reagents, low degradation speed of the spilled oil and long periods of treatment time and the defect that pollutants can be transferred but cannot be degraded in the process of treating oil spilling leakage. Aiming at the defects, the novel biological oil spilling dispersing agent which contains the surfactant and is used for degrading oil spilling microbial strains quickly is developed. Compared with the conventional oil spilling dispersing agent, the biological oil spilling dispersing agent has the obvious advantages of energy conservation, consumption reduction, environment friendliness, emission reduction, direct reduction in pollution and the like and is quick, simple and convenient when applied to the oil spilling accidents. The microbial inoculum capable of degrading the spilled oil quickly has the advantages of high stability, high spilled oil degradation activity, high growth speed and no secondary pollution to the environment. The biological oil spilling dispersing agent and the preparation method thereof can also be applied to on-site biological repair during the emergent leakage pollution accidents of other various petrochemical products.

Description

Background technique [0001] In recent years, with the rapid development of China's economy, the rapid increase in energy consumption of energy and materials such as oil, and the amount of refining of oil exploration and mining and storage and transportation has also increased significantly.However, due to improper operation or accidents, there are often oil spill or discharge, and oil spill accidents will cause serious environmental pollution.This type of oil pollution has become one of various oil pollution, especially the type with the highest frequency of oil pollution at sea, the widest distribution area, and the largest harm.Petroleum pollution will not only cause acute and chronic poisoning of the human body, but also have a huge impact on the growth, reproduction of nature creatures and the entire ecosystem.If the human body inhale high -concentration of petroleum components, it will immediately cause severe obstacles in the central nervous system, tremor, green skin, chaos...
