Problems solved by technology
The disadvantage is that after a period of time in the general filter device, the suspended solid sample particles will form a blockage on the filter screen. As the filtration progresses, the filter screen can no longer filter the suspended solid particles, making the sampling process unable to continue.
[0005] Obviously, the above two suspended solids sampling methods are difficult to truly meet the requirements of suspended solids sampling

The invention discloses a grading sectional acquisition apparatus for water body suspended solids, which belongs to the technical field of environmental monitoring and relates to suspended solid sample acquisition of rivers, lakes and reservoirs. The grading sectional acquisition apparatus comprises a lifting ring, a mooring rope with scales and a grading sectional acquisition apparatus for suspended solids, wherein the mooring rope with scales is wound on a wire shaft, penetrates through the lifting ring and is connected with the grading sectional acquisition apparatus for suspended solids; the acquisition apparatus is in the shape of a circular barrel, divided into a top water outlet part, a middle suspended solid collecting part, a barrel bottom supporting base and a bottom water inlet part; the middle suspended solid collecting part is divided into an upper suspended solid collecting layer, a middle suspended solid collecting layer and a lower suspended solid collecting layer which are stacked from top to bottom in sequence; the three suspended solid collecting layers are connected through a flange plate type structure. The grading sectional acquisition apparatus achieves home positions, weak perturbation and grading sampling of the suspended solids, avoids a filter membrane blockage problem, can be used for obtaining suspended solid samples with different grain sizes, is convenient to operate, good in fidelity, high in precision and strong in representativeness, and can be used for acquiring suspended solid samples in water body of rivers, lakes, reservoirs and the like.
Description
technical field [0001] The invention belongs to the technical fields of environmental monitoring, environmental treatment and suspended matter sample collection, relates to the collection of suspended matter samples of rivers, lakes and reservoirs, and particularly relates to a water suspended matter grading and binning collector. Background technique [0002] The protection and management of water quality in water source areas is the foundation of ensuring safe water supply. Pollutants in source water often exist in the form of dissolved, suspended and sedimentary states. Suspended solids refer to solid substances suspended in water, including water-insoluble inorganic substances, organic substances, sediment, clay, and microorganisms. Suspended solids can not only adsorb a variety of harmful substances, but also contain biochemical processes. They are composite pollutants with high pollutant concentrations and outstanding sensory smell. During the operation of the water s...
