Embodiment 1
[0047] Embodiment 1: a kind of treatment process of efficiently removing marine oil spill, comprises the following steps:
[0048] (1) Air-dry and sieve the sediments taken from the muddy beach at the estuary of the Dagu River, the content of organic matter in the described sediments is 8g / kg, and the density is 2.5g / cm 3 , to obtain particles with a particle size not greater than 35.5 μm;
[0049] (2) Sorting operation:
[0050] ① Filtrate the seawater taken from the sea area of Jiaozhou Bay with a 0.45 μm microporous membrane to obtain filtered seawater;
[0051] ②The appropriate height of the cylindrical reactor is marked as H, and the appropriate height of the bottom of the cylindrical reactor is marked as h; the particles with a particle size not greater than 35.5 μm obtained after air-drying and sieving are mixed with an appropriate amount of filtered seawater in the cylindrical reactor. Mix well in the reactor, make 10g / L seawater solution, and start timing;
