Description
Technical Field
The utility model relates to ocean sampling equipment, in particular to an ocean multichannel in-situ suction filtration device.
Background
Suspended Particulate (SPC) in the ocean, including planktonic microorganisms and suspended silt, is the major source of sediment, which is the major carrier for the transport of many trace elements from surface water to bottom water, and serves an important role in element transport, circulation and removal, and is an established form of elements. The quantity of suspended particles on the surface layer of the water body influences the transparency of the dampening water and the thickness of the true light layer, thereby influencing the photosynthesis and the primary productivity of plankton; the suspended particles can be used as the food of micro-organisms, and the inorganic particles and organic debris can be used as the main food source of benthos after reaching the seabed; seismic or turbidity currents can cause large amounts of sediment to be suspended, greatly increasing the density of the bottom water and often altering the temperature and salinity of the bottom water. Therefore, the accurate observation of the suspended particles has important significance for researching marine material transportation and water body element characteristics. In offshore areas, the deposition of suspended particulate matter affects seawater quality, biocenosis, and geochemical morphology.
At present, the most fundamental mode for measuring the concentration of suspended particulate matters is to obtain a water sample on site, return the water sample to a laboratory and then filter and analyze the water sample; or estimated based on optical, acoustic, density, dielectric constant, etc. measurements. Therefore, the measurement methods thereof are mainly classified into two types, i.e., the conventional method and the modern method. The traditional method is to take water on site (three-point or six-point method), then filter, weigh and calculate the mass concentration of suspended particulate matters of the water sample, which is considered as the most accurate method; however, it is time-consuming and expensive to obtain only a few layers of depth and a large time interval of the suspended particulate data. The modern method is to indirectly observe the concentration of the suspended particles by utilizing sensors such as optics, acoustics, density, dielectric constant and the like, and is characterized by high efficiency, continuous acquisition and capability of obtaining the information of the suspended particles with higher space-time resolution; however, the measurement accuracy is low, and these methods for indirectly observing the concentration of suspended particles require periodic calibration of the equipment and are limited by the applicable measurement depth. Therefore, how to realize the measurement of the concentration of suspended particulate matters at multiple measuring points, full water depth and multiple water layers for a long time in a time-saving and labor-saving manner is a problem which needs to be solved urgently at present. Seawater in-situ filtration is expected to become a beneficial supplement to the traditional laboratory filtration method after seawater is lifted.
