However, since seepage is the movement of the polluted liquid in the pores of the medium, and the shape, size and distribution of the pores are extremely complex, the trajectory of the particles of the seepage polluted liquid is also very irregular and has a random nature.
The traditional seepage model does not consider the tortuous path, but only considers its main flow direction, so it is difficult to obtain the specific seepage situation of pollutants in the medium, and it is also difficult to obtain the distribution of polluted liquid in the medium at different depths
This makes it difficult to analyze the seepage distribution of pollutants in the medium

Embodiment Construction
[0019] The present invention will be further described below in conjunction with accompanying drawing.
[0020] Such as Figure 1 to Figure 4 As shown, the present invention includes a seepage tank 1, four groups of drawable metal strips 4 are respectively inserted on the left and right sides of the seepage tank 1, and each group of metal strips is provided with two pieces, and the ends of the metal strips located inside the seepage tank 1 are provided with Detector 2 and collection tube 3. There are electric wires and data wires inside the metal strip. The wires can supply power to the detector 2 and the collection tube 3. The other end of the data wire is connected to the control system. The detector 2 will send the detected pollutant concentration to the On the computer side, when the user wants to collect a sample of the contaminated liquid at a certain point in the seepage tank 1, a collection signal is sent from the computer, and the collection pipe 3 at the designated ...

The invention discloses a model device for researching a pollutant seepage law. The device comprises a seepage groove, wherein a plurality of groups of metal strips are respectively inserted into twosides of the seepage groove, a detector and a collecting pipe are arranged at an end of the metal strip located in the seepage groove, a pollution liquid distribution groove is formed in the top of the seepage groove, an end of the pollution liquid distribution groove is connected with a pollution liquid configuration box, a homogenizing bin is arranged in the pollution liquid configuration box, storage bins are arranged on two sides of the top of the homogenizing bin, and second flashboards are arranged between the storage bins and the homogenizing bin. The device is advantaged in that a realpollution source emission rule can be simulated, the concentrations of the pollution liquids at different positions in the medium are monitored, and the medium and the pollution liquid sample at thespecified position are collected, so the change mechanism of the pollutants in the medium is revealed, and permeability parameters of the medium, the purification effect of the medium on the pollutants, the migration law of the pollutants and the like are accurately considered.
Description
technical field [0001] The invention relates to a model device, in particular to a model device for studying the seepage law of pollutants. Background technique [0002] In the study of the characteristics of pollutants, the investigation of the seepage of polluted liquid in different media plays an important role in obtaining the permeability parameters of the media, the purification effect of the media on pollutants, and the migration rules of pollutants. However, since seepage is the movement of contaminated liquid in the pores of the medium, and the shape, size and distribution of pores are extremely complex, the movement track of the particles of seepage contaminated liquid is also very irregular and has a random nature. The traditional seepage model does not consider the tortuous path, but only considers its main flow direction, so it is difficult to obtain the specific seepage of pollutants in the medium, and it is also difficult to obtain the distribution of polluted...
