Description

Technical Field

[0001] The present invention relates to the technical field of soil pollutant detection, and in particular to soil pollutant analysis equipment and methods for environmental supervision. Background Art

[0002] Soil and groundwater pollution has become a global environmental problem, so it is urgent to carry out pollution site management and remediation to improve soil environmental quality. At present, soil and groundwater pollution control faces great difficulties. The main limiting factor is that the irregularity and heterogeneity of the spatial distribution of pollutants deep underground make it extremely difficult to detect pollution and define the scope of pollution. The migration and distribution of pollutants in soil and groundwater are not only affected by the characteristics of the pollution source, but also by the spatial structural characteristics of the storage medium (soil). Therefore, compared with the distribution of pollutants in surface water and the atmosphere, the spatial distribution characteristics of pollutants in soil and groundwater are more complex.

[0003] At present, one of the conventional methods for analyzing the distribution characteristics of pollutants in contaminated sites is the geochemical exploration method. The basic principle is to collect contaminated soil samples at different spatial points through drilling, then analyze the pollutant concentration in the soil through the laboratory, and finally obtain the spatial distribution characteristics of the pollutant concentration through spatial interpolation. It can be seen that the accuracy of the distribution characteristics of pollutant concentration depends to a large extent on the number of sampling points or soil samples. The denser the sampling points and the more soil samples analyzed, the more accurately the range of pollutants and their concentration distribution characteristics can be obtained.

[0004] At present, a common method for detecting the concentration of pollutants in the collected contaminated soil samples is the inductively coupled plasma mass spectrometry (ICP-MS) detection method. The ICP-MS detection method has the advantage of high accuracy of the detection results, but it often takes a longer time and cost to complete the detection of pollutant concentrations. Another commonly used detection method is to use a portable X-ray fluorescence spectrometer (PXRF) analyzer for detection (PXRF detection method). The PXRF detection method has the advantages of fast detection speed and low cost, but the accuracy of the detection results is relatively low. However, there is no equipment in the existing technology that combines the advantages of the two, which results in the inability to combine the advantages of the two detections.

[0035] Example 1

[0036] Reference Figure 1-6 The present invention discloses a soil pollutant analysis device for environmental supervision, including a sampling component 100. In this embodiment, the sampling component 100 includes a movable bracket 102. The movable bracket 102 can be moved on the ground. The operator can move the entire device by pushing the movable bracket 102, so that the entire device is moved to the collection position for collection operation. A receiving platform 103 is also provided on the movable bracket 102. The receiving platform 103 is an operator-operable area and is used to receive the collected soil sample. A receiving vessel 104 is provided on the receiving platform 103. The receiving vessel 104 is a glass vessel and is used to receive part of the soil sample. A protective cover body for protecting the receiving vessel 104 is provided on the receiving platform 103. A sampling component 101 is provided between the movable bracket 102 and the receiving platform 103.

[0037] Furthermore, the present invention also includes an analysis component 200, which includes a soil analysis module 201, a concentration detection and analysis module 202, and an interval processing component 203 arranged in a receiving container 104. The interval processing component 203 collects soil samples of different depths and analyzes them synchronously. The soil analysis module 201 and the concentration detection and analysis module 202 are used to synchronously analyze the soil. The analysis equipment is used to establish a detection model corresponding to the target pollutant according to the PXRF concentration and ICP-MS concentration corresponding to each of the M soil samples. The detection model reflects the mapping relationship between the ICP-MS concentration and the PXRF concentration.

[0038] In this embodiment, the sampling component 101 includes a drill probe rod 104 arranged on a movable bracket 102, a drill bit 101a rotatably connected to the lower end of the drill probe rod 104103, a lifting column 101b arranged outside the drill bit 101a, a sample retaining component 101c arranged inside the lifting column 101b, and a connecting rod 101d fixedly installed on the outer surface of the sample retaining component 101c. A movable box 101e is arranged at the uppermost end of the drill bit 101a, and a first bevel gear connected to the drill bit 101a and a second bevel gear meshing with the first bevel gear are arranged in the movable box 101e, and a motor 101f is connected to the second bevel gear.

[0039] Furthermore, the drill bit 101a is provided with a conical drilling portion 101a-1 and a transmission portion 101a-2.

[0040] Specifically, the sample retaining component 101c includes a soil inlet 101c-1 opened inside the lifting column 101b, an active chamber 101c-2 opened inside the lifting column 101b, a soil box 101c-3 installed in a sliding connection inside the active chamber 101c-2, a spring 101c-4 arranged at the bottom of the soil box 101c-3 and fixedly connected to the active chamber 101c-2, a trigger block 101c-5 arranged in a movably connected manner inside the active chamber 101c-2, and a return spring 101c-6 installed in the active chamber 101c-2 and fixedly connected to the trigger block 101c-5;

[0041] Furthermore, the soil inlet 101c-1 is in communication with the movable cavity 101c-2, and the soil material box 101c-3 is provided with a slot having the same size as the soil inlet 101c-1.

[0042] More preferably, one end of the connecting rod 101d is fixedly connected to a baffle 101d-1, and when the soil material box 101c-3 moves, the baffle 101d-1 will be driven to move through the connecting rod 101d.

[0043] It should be noted that three identical groups of sample retaining components 101c are simultaneously arranged inside the lifting column 101b.

[0044] In this embodiment, the adjustment component 300 includes a soil retention tube 302 rotatably connected in the installation groove 300b and a clamping block arranged on the soil retention tube 302, a rotating plate 304a arranged at the lower end of the conversion block 300a, a first guide groove 304b opened on the rotating plate 304a, and a fixed plate 304c arranged at the lower end of the conversion block 300a, a second guide groove 304d is opened on the fixed plate 304c, the first guide groove 304b is arc-shaped, and the two ends of the first guide groove 304b are opened corresponding to the two ends of the second guide groove 304d, and the second guide groove 304d is opened along the radial direction of the fixed plate 304c, and a connecting rod 305 is arranged between the first guide groove 304b and the second guide groove 304d, and each connecting rod 305 is arranged corresponding to the soil retention tube 302.

[0045] Preferably, an ear plate 306 extends downward from the lower end of the soil retention tube 302, a transfer rod 307 is hinged between the lower end of the soil retention tube 302 and the connecting rod 305, a ring gear 308 is arranged on the outer edge of the rotating plate 304a, a driving gear 309 meshing with the ring gear 308 is arranged in the storage box 102c, and a driving motor 309a connected to the driving gear 309 is arranged in the storage box 102c.

[0046] Operation process: When in use, the conveying part 101a-2 rotates to convey the soil upwards. At this time, the soil will enter the soil box 101c-3 from the soil inlet 101c-1. At this time, the conveying part 101a-2 continues to rotate and touches the trigger block 101c-5, causing the trigger block 101c-5 to move back and forth under the elastic force of the return spring 101c-6. The trigger block 101c-5 pushes the soil box 101c-3 so that the soil box 101c-3 will move up and down frequently through the spring 101c-4 at the bottom, causing the soil inside to shake and be evenly placed. When the soil inside the soil box 101c-3 is collected to a certain weight, the soil box 101c- Driven by gravity, the spring 101c-4 will not rebound. At this time, the soil inlet 101c-1 is closed, and the soil sampling is completed. Then, the baffle 101d-1 is driven downward by the connecting rod 101d connected to the soil box 101c-3 to open the second upper sample retaining component 101c. Repeat the above operation to collect the remaining two sample retaining components 101c. Because when the first sample retaining component 101c is collecting, the soil inlets 101c-1 of the two upper sample retaining components 101c are not opened, and the conveying part 101a-2 will continue to transport the soil upward, so the remaining two sample retaining components 101c will collect soil at different depths.

[0047] The driving motor 309a is connected to a wireless data transceiver module via a data connection line. The wireless data transceiver module is electrically connected to the control module 104 via a wireless module. After the electrical connection, the electrical signal is transmitted to the wireless data transceiver module, and then transmitted to the driving motor 309a, thereby driving the driving motor 309a to rotate. The rotation of the driving motor 309a drives the rotation of the rotating plate 304a, thereby changing the position of the plurality of connecting rods 305 (moving from near the edge to near the center of the rotating plate 304a, or moving from the center to the left). When the connecting rod 305 moves to the center, it pulls the soil retention tube 302 to rotate, so that the lower end of the soil retention tube 302 rotates from a position close to the edge to a position close to the center, thereby adjusting the upper end of the connecting rod 305 from a state of being close to each other to a state of being far away from each other, and then the state of the upper end of the soil retention tube 302 is continuously changed by driving the motor 309a in forward and reverse rotation, thereby centrifuging the soil.

[0048] Through the above-mentioned centrifugal action, the soil sample is mixed with the reaction liquid to form a mixture after being acted upon by centrifugal force, thereby facilitating the subsequent measurement of PXRF concentration and ICP-MS concentration. The analysis module is used to establish the PXRF concentration and ICP-MS concentration corresponding to each of the M soil samples to establish a detection model corresponding to the target pollutant, so that the operator can intuitively know the soil pollutant concentration in the current soil environment.

[0050] The present invention also discloses an analysis method of soil pollutant analysis equipment for environmental supervision, comprising:

[0051] Obtain the PXRF concentration and ICP-MS concentration corresponding to each of the M soil samples in the target area. The ICP-MS concentration is obtained by using the ICP-MS detection method to detect the target pollutant, N>M>1;

[0052] According to the PXRF concentration and ICP-MS concentration corresponding to each of the M soil samples, a detection model corresponding to the target pollutant is established, and the detection model reflects the mapping relationship between the ICP-MS concentration and the PXRF concentration;

[0053] Determine the ICP-MS concentration corresponding to each of the N soil samples according to the detection model and the PXRF concentration corresponding to each of the N soil samples;

[0054] According to the ICP-MS concentrations corresponding to the N soil samples and the sampling positions corresponding to the N soil samples, the concentration distribution characteristics of the target pollutant in the target area are determined.

[0055] Among them, after each soil sample is collected, a specific analysis can be carried out to mark the different layers of the current soil.
