[0035] Example

[0036] In current technology, when leaching technology is applied to the field of soil remediation, the leaching devices used are generally complex in structure, have high power consumption, and are inefficient in collecting and utilizing the leaching solution. At the same time, the relevant society is difficult to exist in the soil for many years, resulting in waste of resources and increased environmental pressure.

[0037] To do this, see Figure 1-2 The utility model provides a device for collecting and extracting nutrient leaching liquid of farmland soil, comprising: a liquid collecting box 1 and a filtrate collector 4 located below the liquid collecting box 1, the filtrate collector is connected to the liquid collecting box 1 through a connecting pipe a3, and the filtrate collector 4 comprises a ventilation device and a filtrate extraction device;

[0038] Among them, a filtrate collector 4 is configured below the liquid collecting box 1. The collector is closed on all sides and can effectively filter out impurities in the eluent. The device is connected to the air inlet 8 on the periphery of the soil through a natural gas pipeline. This design allows the gas to enter the natural gas pipeline through the air inlet 8 and then enter the collector when the eluent flows through the filtrate collector 4. The setting of this ventilation device not only increases the dissolved oxygen content in the eluent, provides favorable conditions for the growth of microorganisms, but also helps to promote the biodegradation of substances. At the same time, the introduction of gas helps to improve the extraction efficiency of the substance, making the elution process more efficient.

[0039] The inner bottom of the liquid collecting tank 1 is provided with an inclined surface 2 , and a filler 21 is arranged on the inclined surface 2 .

[0040] Among them, a connecting pipe hole is provided at the bottom of the liquid collecting box 1, which is used to allow the eluent in the liquid collecting box 1 to enter the filtrate collector 4 through the connecting pipe a3; the ventilation device balances the air pressure by passing gas into the filtrate collector 4, and can also increase the dissolved oxygen content in the eluent, and can also increase the extraction efficiency.

[0041] The liquid collecting box 1 comprises an inclined surface 2, and the whole box body presents a heptahedron structure with one end open. There is a pipe hole at the bottom of the inclined surface 2 for connecting to the filtrate collector 4 below.

[0042] The filtrate collector 4 is a rectangular parallelepiped structure, with three pipe holes on one side, one for connecting the upper end of the liquid collecting box 1, and the other two for connecting the vent and the filtrate collecting port 7, which is connected to the filtrate collector 4 through a natural gas pipeline. Applying a certain suction force at the collecting port 7 can drain the eluent in the filtrate collector 4, which is convenient for sampling and collection. This design makes the collection of eluent more convenient and quick, and improves the use efficiency of the entire device.

[0043] Further as Figure 1-2 As shown, it is worth explaining in detail that the filtrate extraction device includes a connecting pipe c6 connected to the connecting pipe port provided on the filtrate collector 4, and a filtrate collecting port 7 is provided at the top of the connecting pipe c6.

[0044] The filtrate collecting port 7 draws the eluent out of the filtrate collector 4 by suction.

[0045] Further as Figure 1-2 As shown, it is worth explaining in detail that the ventilation device includes a connecting pipe b5 connected to the connecting pipe port provided on the filtrate collector 4, and an air inlet 8 is provided at the top of the connecting pipe b5.

[0047] The eluent is collected through the upper part of the liquid collecting box 1, and a layer of filler 21 is provided at the bottom of the liquid collecting box 1 to filter impurities and prevent large particles from clogging the pipe holes. The device is made of high-quality stainless steel and natural gas pipeline materials, which can greatly reduce pollution to the environment and can be buried underground for a long time.

[0048] Further as Figure 1-2As shown, it is worth specifically explaining that the liquid collecting box 1 is a rectangular box, and the length, width and height are 120 cm, 60 cm and 15 cm respectively. The bottom end of the liquid collecting box 1 is designed as a triangular prism of the same size, and the two are connected into one by a rectangular parallelepiped with an open end. The filtrate collecting box is a box closed on four sides, and the length, width and height are 30 cm, 20 cm and 60 cm respectively. The materials used to make the liquid collecting box 1 and the filtrate collector 4 are both stainless steel materials. The connecting pipes a3, b5 and c6 are all natural gas pipes, and the diameters of the connecting pipes a3, b5 and c6 are all 1 cm.

[0049] It should be noted that one end of the natural gas pipeline connected to the filtrate collecting port 7 in the filtrate collector 4 is tilted at a certain angle, which is conducive to the extraction of the eluent from the filtrate collector 4 .

This design allows the gas to enter the natural gas pipeline through the air inlet 8 and then enter the collector when the eluent flows through the filtrate collector 4. The setting of this ventilation device not only increases the dissolved oxygen content in the eluent, provides favorable conditions for the growth of microorganisms, but also helps to promote the biodegradation of substances. At the same time, the introduction of gas helps to improve the extraction efficiency of the substance, making the leaching process more efficient;

[0053] The coordinated use of the ventilation device and the filtrate collection device not only improves the extraction efficiency of the substance, but also contributes to the biodegradation of the substance and the protection of the environment;

The elution tray is buried at a depth of 60 cm, and the eluent collection device is buried at a depth of 90 cm. The inside of the elution tray is filled with nylon mesh, quartz sand and in-situ soil from bottom to top. The sampling tube is 100 cm above the ground surface. The sampling tube and ventilation tube are sealed and opened during sampling to prevent rainwater, insects and other impurities from entering the device. After the device is buried, the soil of the same soil layer is backfilled in situ to minimize the disturbance of the arable soil.
