Embodiment Construction
[0021] Attached below Figure 1-5 , the present invention is described in detail.
[0022] figure 1 For the plan view of the test circulating water tank 14 that the present invention adopts, it is made up of three parts: circulating water tank 14, power unit 1 and sampling device 2, and this circulating water tank 14 is made of very little plexiglass to adsorption, migration, diffusion influence, puts On the horizontal plane 1m above the ground, the bottom surface should choose an appropriate slope according to the test water flow conditions. The width of the tank is 0.15m, and the total circumference is 10m. The length of the two straight sections is 3.5m, the inner diameter of the curved section is 0.41m, and the outer diameter is 0.56m. The two straight sections of the plexiglass circulating water tank 14 are the main operating areas in the test, and the test power unit 1 is set on one side, and the sampling device 2 is set on the other side. The test power unit 1 is comp...

The invention relates to a method for simulating a pollutant adsorption and migration rule of Yellow River silt through a hydraulic model, and belongs to the field of water conservancy. The international patent classification (IPC) numbers are E02B 1 / 00 and E02B 1 / 02. The hydraulic model adopted in the method is composed of an organic glass circulating water tank, a power device and a sampling device. The power device comprises a variable-speed motor, a conveying belt and a water wheel. A shell and blades of the water wheel are all made of organic glass. The sampling device is composed of a fixing device and a sampling tube. The fixing device is provided with a longitudinal adjusting bolt and a transverse adjusting lead screw. The method can dynamically simulate the migration and conversion processes of pollutants in natural rivers and enhance understanding to the dispersion process, the adsorption and desorption reaction mechanism and mutual action, and accordingly the method is significant.
Description
Technical field: [0001] The invention relates to a method for using a hydraulic model to simulate the adsorption and migration of pollutants by Yellow River sediment. The IPC international patent classification numbers E02B1 / 00 and E02B1 / 02 belong to the field of water conservancy. Background technique: [0002] With the increasing shortage of water resources, the role of Yellow River water in protecting industrial and agricultural water and drinking water for residents in cities and rural areas along the Yellow River has also become increasingly prominent. How to ensure that the Yellow River water is not polluted, and how to eliminate pollution as soon as possible once polluted, is of great importance to protection. The water quality of the Yellow River is very important. Therefore, studying the adsorption of pollutants and their migration and diffusion laws by the Yellow River sediment has become an important topic for the management and protection of the Yellow River. A ...
