Description

Technical Field

[0002] Marine sediments refer to the general term for seabed sediments formed by various marine sedimentation processes. Materials deposited on the seabed with seawater as the medium. Sedimentation can generally be divided into three different processes: physical, chemical and biological. Since these processes are often not carried out in isolation, sediments can be regarded as geological bodies produced by comprehensive actions. Traditionally, sediments are divided into the following categories according to depth: nearshore sediments (0-20 meters), shallow sea sediments (20-200 meters), semi-deep sea sediments (200-2000 meters), and deep sea sediments (greater than 2000 meters).

[0003] At present, when filtering and purifying marine sediment samples, only the water in the samples can be filtered out, which is not convenient for removing stones or plastics in the samples. The marine sediments contain some stones or plastics, which will affect the subsequent detection and processing of the sediments if they are not removed in time.
