Embodiment approach 1

[0047] Embodiment 1: The method for in-situ remediation of oil pollution by pioneer plants and clamworms on this tidal flat includes the following steps:

[0048]1) Build a processing unit: such as figure 1 As shown, according to the size and depth of the oil pollution, dig out the oil pollution, mix it with soil, coal cinder, sandstone or other readily available solid materials to form high-oil soil, put it aside for later use, and form when digging oil pollution In the pit, first spread the grass felt layer 1 or the oil-absorbing paper layer, then spread the high oil soil layer 2 on the grass felt layer 1, then spread the straw layer 3, and finally fill the soil layer 4 to form One or more repair units.

[0049] A film layer 5 is also provided below the straw felt layer, and the film layer 5 is made of plastic film or oil-absorbing paper. At least one through hole 6 is opened on every square meter of the film layer 5, and the area of ​​the through hole 6 is between 3-5 cm2...

Abstract

The invention relates to a method for the in situ restoration of petroleum pollution through the combination of pioneer plants on a tidal bank and clam worms. A method for the in situ restoration of petroleum pollution through the combination of pioneer plants on a tidal bank and clam worms comprises the steps of constructing a processing unit, planting reeds, carrying out broadcast sowing on Suaeda heteroptera and adding clam worms in order to fill up the gap in the prior art. The method for the in situ restoration of petroleum pollution through the combination of pioneer plants on a tidal bank and clam worms has the advantages of high survival rate, fast degradation, and rapid improvement of the oil stain zone landscape, is suitable for the in situ restoration of petroleum pollution, and is especially suitable for the biological restoration of petroleum pollution of watersides of sea beaches, river banks, lake beaches and the like.

Description

technical field [0001] The invention relates to a method for remediating oil pollution in situ by combining pioneer plants and clam worms on tidal flats. Background technique [0002] Marine oil pollution refers to the pollution caused by oil and its refined products (gasoline, kerosene, diesel, etc.) entering the marine environment during the process of exploitation, refining, storage, transportation and use. Ways include all kinds of oily waste water injected into the ocean through rivers or directly; offshore oil tanker oil spills, discharges, and oil tanker accidents; submarine oil field mining spills and blowouts; the settlement of petroleum hydrocarbons that escape into the atmosphere and natural oil spills on the seabed, etc. It mainly occurs in estuaries, harbors and offshore waters, around offshore oil transportation lines and subsea oil fields. [0003] my country's "Marine Oil Pollution Level" is positioned according to the amount of oil spilled. Small oil spill ...
