Simultaneous Measurement Method for Vertical Distribution of Suspended Fine Particulate Matter in Rivers
A technology of vertical distribution and synchronous measurement, which is applied in particle suspension analysis, suspension and porous material analysis, and measurement devices. It can solve problems such as complex implementation procedures, inability to achieve synchronous measurement, and interference with the concentration distribution of fine particle suspensions. To achieve the effect of inhibiting the development

Embodiment 1
[0029] This embodiment is preferably carried out in an indoor rectangular cross-section water tank, the water tank is 0.8 m wide, 32 m long, the experimental water depth is 40 cm, and the water flow velocity is 0.2 m / s. Before the start of the experiment, 0.8 cm thick hollow glass beads were spread on the bottom of the tank. The glass beads had a diameter of 110 μm and a specific gravity of 2.0.
[0030] Such as figure 1 and image 3 As shown, the present embodiment includes: eight streamlined sampling bottles 1 are arranged in parallel along the same vertical direction and suspended on a carbon steel connecting rod 6 with a diameter of 2 mm, and the connection point is at the side of each sampling bottle at a position 9 cm away from the mouth of the bottle. . The distance between each sampling bottle 1 is 4cm, and the center line of the first sampling bottle at the bottom is 5cm away from the bed surface.
[0031] The diameter of the mouth of the streamlined sampling bottl...
Embodiment 2
[0042] This embodiment is preferably carried out in a section of natural straight river section with a width of 5.2m and a length of 16m, with a water depth of 100cm and a water velocity of 0.27m / s. The median diameter of suspended fine particulate matter in the river was 125 μm, and the mean square deviation was 83 μm.
[0043] Such asfigure 1 and image 3 As shown, the present embodiment includes 19 streamlined sampling bottles 1, arranged along the same vertical direction, suspended on the connecting rod 6, the connecting rod is a carbon steel rod with a diameter of 2mm, and the connecting point is at the side of each sampling bottle from the bottle. At the position of 9.5cm from the mouth. The distance between the 19 sampling bottles is 5 cm, and the centerline of the first sampling bottle at the bottom is 6 cm from the bottom bed surface.
[0044] The diameter of the mouth of the streamlined sampling bottle is 2.5mm; the uniform height of the bottle body is 2.6cm; the h...
