Problems solved by technology

However, these oil spill cleanup methods have certain limitations.
The traditional physical method is inefficient and labor-intensive, and it is difficult to remove the oil spill completely
Most oil dispersants and oil collectors are prone to secondary pollution to the ocean
The advantages of using biological methods to remediate crude oil-contaminated seawater are that it is safe, non-toxic, biodegradable, and usually does not cause secondary pollution to the environment. Suitable for large area marine oil spill remediation

Abstract

The invention relates to a method for environment-friendly efficient restoration against marine oil spill. The method comprises the following steps: a step (1) of taking, by mass parts, 20-27 parts of bran, 20-27 parts of wheat straw, 19-25 parts of wood shavings, 16-22 parts of duckweed, 12-17 parts of grape seeds, 10-17 parts of apple peel, 9-16 parts of pomegranate rind, 9-16 parts of scale, 7-14 parts of bitter gourd seedlings, 7-14 parts of mulberry leaves, 5-9 parts of tremella fuciformis, 3-4 parts of vermiculite, 6-10 parts of east wall earth, 4-5 parts of distillers' dried grains and 3-5 parts of dry yeast powder; a step (2) of adding purifier water into the mixed material in the step (1), performing fermentation in the absence of light, filtering the mixed materials, and taking obtained fermentation liquid; a step (3) of evenly mixing the fermentation liquid, alkyl glycoside and polysorbate; a step (4) of placing petroleum degrading strains and the mixture obtained in the step (3) into seawater polluted by crude oil. The method has the advantage of being high in oil spill degradation efficiency.

Description

technical field [0001] The invention belongs to the field of marine oil spill pollution treatment, and in particular relates to an environmentally friendly and ecological restoration method for marine oil spill pollution. Background technique [0002] With the increase of global demand for petroleum products and marine transportation of petroleum, the amount of offshore petroleum transportation and offshore petroleum exploration has increased rapidly, and marine oil spill accidents have also continued to increase, which seriously threatens the ecological environment of the ocean and coastal areas. In recent years, the increasingly serious marine oil spill pollution has aroused the attention of marine management departments and ecologists all over the world. Oil spills mostly occur at sea, and the oil drifting to the coastline with the wind and waves not only causes serious environmental pollution, but also seriously affects the environmental quality and biodiversity index of...
