Description

Rapid sampling device suitable for stony sediment 0503949
Technical field
The invention relates to the technical field of sediment collection, and in particular to a rapid sampling device suitable for stony sediment.
Back ground
Sediment, also known as deposit, comes from: natural erosion products of minerals, rocks and soil, the product of biological process, degradation of organic matter, the mixture formed by sewage discharge and riverbed parent material and the accumulated substances at the bottom of the water body with the migration of water flow. Water, aquatic organisms and sediment constitute a complete water environment system. Various pollutants are accumulated in the sediment, which can record the pollution history of a given water environment and reflect the accumulation of pollutants that are difficult to degrade. Some pollutants accumulated in the sediment are easy to diffuse into the water body, leading to secondary pollution of water quality.
In order to fully understand the present situation of water environment, the pollution history of water environment and the potential danger of sediment pollution to human body, sediment monitoring is an important link that can not be ignored in water environment monitoring. By analyzing the physical, chemical and biological characteristics of sediment and studying the environment of sediment, the location of pollution sources can be determined and the degree and time of water pollution can be judged.
When monitoring the sediment, it is necessary to collect the sediment first. Most of the existing sediment sampling methods are manual diving sampling or mechanical grab bucket.
Manual sampling of sediment is mostly suitable for soil sediment, and the sampling depth is limited. Although mechanical grab bucket is suitable for sampling sediment with most types, it is necessary to use mechanical grab bucket to destroy rocks for stony sediment. On the one hand, the sampling speed is too slow, on the other hand, it is easy to damage the grab bucket.
