Description

Technical Field

[0001] This invention relates to the field of sludge treatment and disposal technology in river and lake ecological management, specifically to an adaptive sludge pollutant separation device and method. Background Technology

[0002] Ecological dredging is an important measure to improve the water quality and aquatic ecosystem of rivers and lakes. However, the "resource utilization, harmlessness, and volume reduction" of the dredged sediment has not yet been adequately addressed. Sediment treatment and resource utilization face significant challenges. Currently, sludge is mostly treated by dewatering and solidification to reduce its volume, and then utilized through stockpiling, land reclamation, or material processing. The solidified sludge after dewatering contains a large amount of organic or heavy metal pollutants. Traditional treatment methods easily lead to pollutant migration, causing "secondary pollution," which is a major challenge in sludge treatment and disposal. This device and method can use ultrasonic vibration to fully separate pollutant molecules from the soil particles of the sludge and allow them to enter the water body. After mud-water separation, clean soil is obtained, and the effluent undergoes further purification, effectively avoiding "secondary pollution" and providing a better approach for the treatment and disposal of dredged sediment from various types of rivers, lakes, and reservoirs, as well as sludge from wastewater treatment plants.

[0003] Based on this technical background, the present invention studies an adaptive sludge pollutant separation device and method. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an adaptive sludge pollutant separation device and method. The device utilizes a diversion baffle to guide a small portion of highly polluted sludge into a test area, while the majority is guided into an ultrasonic generating container. The test area rapidly analyzes and determines the ultrasonic vibration frequency of the highly polluted sludge, and transmits this frequency to the ultrasonic generating container to perform ultrasonic vibration on the highly polluted sludge. This achieves maximum separation of pollutants from soil particles in the sludge, resulting in clean soil. Compared with traditional treatment methods, this method can prevent pollutant overflow during sludge reuse, thus preventing "secondary pollution."

[0005] To achieve the above objectives, a first aspect of the present invention provides an adaptive sludge pollutant separation device, comprising:

[0006] A high-pollution mud input pipe is provided with a test area and a diversion baffle. The test area is used to determine the ultrasonic vibration frequency of the high-pollution mud, and the diversion baffle is used to divert a small portion of the high-pollution mud input into the high-pollution mud input pipe to the test area.

[0007] An ultrasonic generator container is used to ultrasonically vibrate the high-pollution mud transported from the high-pollution mud input pipe. It is connected to the test area through the high-pollution mud test area discharge inlet pipe. The high-pollution mud test area discharge inlet pipe is equipped with a test area bidirectional pump. The bidirectional pump is used to extract the lower soil after ultrasonic vibration for testing, optimize the ultrasonic vibration frequency, and empty the test area after the test.

[0008] The tailwater discharge pipe is equipped with a float ring and a tailwater discharge pump. The float ring is located at the head of the tailwater discharge pipe and is used to float on the polluted water after ultrasonic vibration and work with the tailwater discharge pump to extract the upper layer of polluted water, while avoiding disturbance to the lower soil layer, thus fully realizing mud-water separation.

[0009] A second aspect of the present invention provides a method for separating sludge contaminants in the above-described apparatus, comprising:

[0010] By coordinating the main control unit, bidirectional pump, multiple contaminant removal frequency testing units, signal transmission path, and ultrasonic generator container, the optimal ultrasonic vibration frequency for contaminant removal in highly contaminated sludge is dynamically adjusted.

[0011] By working together with the main control unit, ultrasonic generator container and soil pollution monitoring probe, ultrasonic vibration is applied to highly polluted mud at the optimal frequency.

[0012] Once the pollutant content in the lower soil reaches the cleanliness standard, ultrasonic vibration is stopped, and the pollutant-containing water is pumped out through the tailwater discharge pump and tailwater discharge pipe.

[0013] When the soil pollution monitoring probe measures that the pollutant content in the lower soil layer still does not meet the cleanliness standard, the ultrasonic vibration frequency of the highly polluted mud is re-determined through the coordinated operation of the main control unit, bidirectional pump, ultrasonic generator container and multiple pollution removal frequency testing units.

[0014] The beneficial effects of this invention include:

[0015] (1) The adaptive sludge pollutant separation device proposed in this invention uses a diversion baffle to introduce a small portion of highly polluted sludge into the test area and the majority into the ultrasonic generating container. The test area quickly analyzes and determines the ultrasonic vibration frequency of the highly polluted sludge and transmits the frequency to the ultrasonic generating container to perform ultrasonic vibration on the highly polluted sludge. This achieves maximum separation of pollutants from soil particles in the sludge and obtains clean soil. Compared with traditional treatment methods, it can prevent pollutants from overflowing during the reuse of sludge and causing "secondary pollution".

[0016] (2) The adaptive sludge pollutant separation device proposed in this invention has a bidirectional pump that can extract the lower soil after ultrasonic vibration for testing, optimize the ultrasonic vibration frequency, and drain the test after the test; the float ring is set at the head of the tailwater discharge pipe, which can float on the polluted water after ultrasonic vibration and the tailwater discharge pump can extract the upper water and avoid disturbing the lower soil, thus fully realizing the separation of mud and water.

[0017] (3) The adaptive sludge pollutant separation device proposed in this invention has a soil pollution monitoring probe set at the bottom of the ultrasonic generator container to ensure that the bottom soil is tested; the outlet of the high-pollution mud test area discharge inlet pipe connected to one side of the ultrasonic generator container is located in the lower soil layer to ensure that the sample extracted for testing is the soil to be treated; the spare pollution removal frequency test unit interface can provide a spare test interface to improve test accuracy.

[0018] (4) The adaptive sludge pollutant separation method proposed in this invention achieves dynamic adjustment of the pollutant removal frequency in sludge by working in conjunction with the main control unit, ultrasonic generating container, bidirectional pump, tailwater discharge pump, multiple pollutant removal frequency test units and signal transmission path, thereby separating the pollutants from the soil.

[0019] (5) The adaptive sludge pollutant separation method proposed in this invention can automatically obtain the optimal ultrasonic vibration frequency of highly polluted sludge through target frequency testing, target frequency translation search and cyclic target frequency clamping search operation, while improving the accuracy of ultrasonic vibration frequency.

Detailed Implementation

[0027] Preferred embodiments of the invention will now be described in more detail. While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0028] This invention provides an adaptive sludge pollutant separation device, such as... Figure 1 As shown, it includes:

[0029] The high-pollution mud input pipe 1 is equipped with a test area and a diversion baffle 5. The test area is used to determine the ultrasonic vibration frequency of the high-pollution mud, and the diversion baffle 5 is used to divert a small portion of the high-pollution mud input into the high-pollution mud input pipe 1 to the test area.

[0030] The ultrasonic generator container 7 is used to ultrasonically vibrate the high-pollution mud transported from the high-pollution mud input pipe 1. It is connected to the test area through the high-pollution mud test area discharge inlet pipe 2. The high-pollution mud test area discharge inlet pipe 2 is equipped with a test area bidirectional pump 15. The bidirectional pump 15 is used to extract the lower soil 9 after ultrasonic vibration for testing, optimize the ultrasonic vibration frequency, and empty the test area after the test.

[0031] The tailwater discharge pipe 2 is equipped with a float ring 6 and a tailwater discharge pump 4. The float ring 6 is located at the head of the tailwater discharge pipe 2 and is used to float on the upper water body 8 after ultrasonic vibration and work with the tailwater discharge pump 4 to pump out the upper water body 8.

[0032] In this invention, a small portion of the highly polluted sludge in the input pipe is directed to the test area using a diversion baffle, while the majority is directed to the ultrasonic generating container. The test area determines the optimal ultrasonic vibration frequency for the highly polluted sludge, and this frequency is transmitted to the ultrasonic generating container to perform ultrasonic vibration on the highly polluted sludge. This achieves maximum separation of pollutants from soil particles in the sludge, resulting in clean soil. Compared with traditional treatment methods, this method can prevent the overflow of pollutants during sludge reuse, which could lead to "secondary pollution".

[0033] In this invention, the bidirectional pump can extract the lower layer of soil after ultrasonic vibration for testing, optimize the ultrasonic vibration frequency, and empty the test area after the test; the float ring is set at the head of the tailwater discharge pipe, which can float on the polluted water after ultrasonic vibration, and the upper polluted water is extracted by the tailwater discharge pump to achieve mud-water separation.

[0034] According to the present invention, a soil pollution monitoring probe 10 is provided at the bottom of the ultrasonic generating container 7, and the soil pollution monitoring probe 10 is used to measure the content of pollutants in the lower soil layer 9;

[0035] The test area is equipped with multiple contamination removal frequency test units 11 and multiple backup contamination removal frequency test unit interfaces 12;

[0036] Multiple contamination removal frequency testing units 11 are used to determine the ultrasonic vibration frequency of highly contaminated sludge;

[0037] Multiple backup pollution removal frequency test unit interfaces 12 are used to connect new pollution removal frequency test units 11;

[0038] The outlet of the discharge pipe 2 of the high-pollution mud test area is located in the lower soil layer 9, and the pipe opening on one side of the ultrasonic generator container 7 is connected to the ultrasonic generator container 7.

[0039] According to the present invention, it further includes:

[0040] The main control unit 14 communicates in real time with at least one of the ultrasonic generating container 7, the bidirectional pump 15, the tailwater discharge pump 4, and the multiple pollution removal frequency testing units 11 through the signal transmission path 13.

[0041] According to the present invention, the main control unit 14 communicates in real time with multiple pollution removal frequency testing units 11 to determine the ultrasonic vibration frequency of highly polluted sludge.

[0042] The main control unit 14 communicates with the ultrasonic generating container 7 in real time to control the ultrasonic generating container 7 to perform ultrasonic vibration on the highly polluted mud at a determined ultrasonic vibration frequency.

[0043] The main control unit 14 communicates in real time with the tailwater discharge pump 4 and the soil pollution monitoring probe 10. When the soil pollution monitoring probe 10 measures that the pollutant content in the lower soil 9 has decreased to the cleanliness standard, it feeds back to the main control unit 14. The main control unit 14 then sends a control command to the tailwater discharge pump 4 to pump out the upper water 8.

[0044] Preferably, the main control unit 14 communicates in real time with the bidirectional pump 15, the soil pollution monitoring probe 10, and multiple pollution removal frequency testing units 11. When the soil pollution monitoring probe 10 measures that the pollutant content in the lower soil layer 9 does not meet the standard, the main control unit 14 feeds the information back to the bidirectional pump 15. The bidirectional pump 15 extracts the lower soil layer 9 from the ultrasonic generating container 7 to the test area, and uses multiple pollution removal frequency testing units 11 to redetermine the ultrasonic vibration frequency of the highly polluted mud.

[0045] In this invention, the soil pollution monitoring probe is located at the bottom of the ultrasonic generator container to ensure that the test layer soil is intact; the outlet of the discharge pipe of the high-pollution mud test area is located in the lower soil layer to ensure that the sample extracted for testing is the soil to be treated; the spare pollution removal frequency test unit interface can provide a spare test interface to improve test accuracy.

[0046] The present invention also provides a method for separating sludge pollutants in the above-described apparatus, such as... Figure 2A and Figure 2B As shown, it includes:

[0047] The optimal ultrasonic vibration frequency for removing pollutants from highly polluted sludge is dynamically adjusted through the coordinated operation of the main control unit 14, bidirectional pump 15, multiple pollutant removal frequency testing units 11, signal transmission path 13, and ultrasonic generating container 7.

[0048] The main control unit 14, the ultrasonic generator container 7 and the soil pollution monitoring probe 10 work together to perform ultrasonic vibration on highly polluted mud at the optimal frequency.

[0049] Once the pollutant content in the lower soil layer 9 is reduced to the cleanliness standard, ultrasonic vibration is stopped, and the upper water layer 8 containing pollutants is pumped out through the tailwater discharge pump 4 and the tailwater discharge pipe 3.

[0050] When the soil pollution monitoring probe 10 measures that the pollutant content in the lower soil layer 9 does not meet the standard, the ultrasonic vibration frequency of the highly polluted mud is re-determined through the coordinated operation of the main control unit 14, the bidirectional pump 15, the ultrasonic generating container 7, and multiple pollution removal frequency testing units 11.

[0051] According to the present invention, the optimal frequency for pollutant removal in highly polluted sludge is dynamically adjusted by the coordinated operation of the main control unit 14, the bidirectional pump 15, multiple pollutant removal frequency testing units 11, the signal transmission path 13, and the ultrasonic generating container 7, including:

[0052] After the highly polluted mud is sent into the highly polluted mud input pipe area 1, a small amount of mud is obtained through the diversion baffle 5 and enters the test area. The initial optimal ultrasonic vibration frequency for pollutant removal is obtained by analyzing multiple pollution removal frequency test units 11 and main control unit 14. This frequency is transmitted in real time to the ultrasonic wave generating container 7 through the signal transmission path 13 for ultrasonic vibration. During the ultrasonic vibration process, the lower soil 9 is extracted by the bidirectional pump 15 in the test area. The optimal ultrasonic vibration frequency is determined by the dynamic analysis of the lower soil using multiple pollution removal frequency test units 11 and main control unit 14 and transmitted in real time.

[0053] The main control unit 14, the ultrasonic generating container 7, and the soil pollution monitoring probe 10 work together to perform ultrasonic vibration on highly polluted mud using the optimal ultrasonic vibration frequency, including:

[0054] The ultrasonic generating container 7 uses the optimal ultrasonic vibration frequency for pollutant removal to fully vibrate the highly polluted mud, and the soil pollution monitoring probe 10 monitors the pollutant concentration in the lower soil layer 9 in real time and transmits the concentration to the main control unit 14.

[0055] According to the present invention, the method of pumping out the polluted upper water body 8 through the tailwater discharge pipe 3 via the tailwater discharge pump 4 includes:

[0056] Turn on the tailwater discharge pump 4, and use the float ring 6 to descend synchronously with the upper water body 8 containing pollutants through the tailwater discharge pipe 3 to completely remove the upper water body 8 for subsequent purification treatment. The remaining lower soil body 9 is then treated and disposed of for resource recovery.

[0057] When the pollutant content in the lower soil layer 9 measured by the soil pollution monitoring probe 10 does not meet the standard, the ultrasonic vibration frequency of the highly polluted slurry is re-determined through the coordinated operation of the main control unit 14, the bidirectional pump 15, the ultrasonic generating container 7, and multiple pollution removal frequency testing units 11, including:

[0058] When the soil pollution monitoring probe 10 measures that the pollutant content in the lower soil layer 9 does not meet the standard, the main control unit 14 feeds the information back to the bidirectional pump 15. The bidirectional pump 15 draws the lower soil layer 9 from the ultrasonic generating container 7 to the test area, and uses multiple pollution removal frequency test units 11 to redetermine the ultrasonic vibration frequency of the highly polluted mud.

[0059] In this invention, the adaptive separation of silt and pollutants is achieved by the main control unit working in conjunction with the ultrasonic generating container, the bidirectional pump, the tailwater discharge pump, multiple pollution removal frequency testing units, and the signal transmission path.

[0060] According to the present invention, the frequency adjustment method in dynamically adjusting the optimal ultrasonic vibration frequency for pollutant removal in highly polluted slurry and re-determining the ultrasonic vibration frequency of highly polluted slurry includes:

[0061] The initial frequency range and frequency interval are set according to the number of multiple pollution removal frequency test units 11, and the target frequency is tested.

[0062] If the target frequency obtained from the test is outside the initial frequency range, the frequency range and frequency interval are reset to perform a target frequency translation search.

[0063] If the target frequency obtained from the test is within the initial frequency range or the reset frequency range, then narrow the frequency range and frequency interval to perform a target frequency squeeze search.

[0064] Based on the target frequency obtained by the target frequency squeeze search, the frequency range and frequency interval are further narrowed to perform the target frequency squeeze search. This process is repeated multiple times until the test accuracy of the target frequency is achieved.

[0065] Preferably, setting an initial frequency range and frequency interval based on the number of multiple pollution removal frequency test units 11, and conducting tests at the target frequency includes:

[0066] New pollution removal frequency test units 11 are installed on multiple spare pollution removal frequency test unit interfaces 12 respectively. The initial frequency range and frequency interval are set according to the number of the original multiple pollution removal frequency test units 11 and the number of new pollution removal frequency test units 11, and the target frequency is tested.

[0067] In this invention, the optimal ultrasonic vibration frequency for highly polluted mud can be automatically obtained through target frequency testing, target frequency translation search, and cyclic target frequency clamping search operations, while improving the accuracy of ultrasonic vibration frequency.

[0068] The present invention will be described in more detail below through embodiments.

[0069] Example 1:

[0070] like Figure 1 As shown, this embodiment provides an adaptive sludge pollutant separation device, including:

[0071] The high-pollution mud input pipe 1 is equipped with a test area and a diversion baffle 5. The test area is used to determine the ultrasonic vibration frequency of the high-pollution mud, and the diversion baffle 5 is used to divert a small portion of the high-pollution mud input into the high-pollution mud input pipe 1 to the test area.

[0072] The ultrasonic generator container 7 is used to ultrasonically vibrate the high-pollution mud transported from the high-pollution mud input pipe 1. It is connected to the test area through the high-pollution mud test area discharge inlet pipe 2. The high-pollution mud test area discharge inlet pipe 2 is equipped with a test area bidirectional pump 15. The bidirectional pump 15 is used to empty the test area or extract the lower soil 9 after ultrasonic vibration for testing, and optimize the ultrasonic vibration frequency.

[0073] The tailwater discharge pipe 2 is equipped with a float ring 6 and a tailwater discharge pump 4. The float ring 6 is located at the head of the tailwater discharge pipe 2 and is used to float on the upper water body 8 after ultrasonic vibration and work with the tailwater discharge pump 4 to pump out the upper water body 8.

[0074] The bottom of the ultrasonic generator container 7 is equipped with a soil pollution monitoring probe 10, which is used to measure the content of pollutants in the lower soil layer 9.

[0075] The test area is equipped with multiple contamination removal frequency test units 11 and multiple backup contamination removal frequency test unit interfaces 12;

[0076] Multiple contamination removal frequency testing units 11 are used to determine the ultrasonic vibration frequency of highly contaminated sludge;

[0077] Multiple backup pollution removal frequency test unit interfaces 12 are used to connect new pollution removal frequency test units 11;

[0078] The outlet of the discharge pipe 2 of the high-pollution mud test area is located in the lower soil layer 9, and the pipe opening on one side of the ultrasonic generating container 7 is connected to the ultrasonic generating container 7.

[0079] The apparatus in this embodiment also includes:

[0080] The main control unit 14 communicates in real time with at least one of the ultrasonic generating container 7, the bidirectional pump 15, the tailwater discharge pump 4, and multiple pollution removal frequency testing units 11 through the signal transmission path 13.

[0081] The main control unit 14 communicates in real time with multiple pollution removal frequency testing units 11 to determine the ultrasonic vibration frequency of highly polluted mud.

[0082] The main control unit 14 communicates with the ultrasonic generating container 7 in real time to control the ultrasonic generating container 7 to perform ultrasonic vibration on the highly polluted mud at a determined ultrasonic vibration frequency.

[0083] The main control unit 14 communicates in real time with the tailwater discharge pump 4 and the soil pollution monitoring probe 10. When the soil pollution monitoring probe 10 measures that the pollutant content in the lower soil 9 has decreased to the clean standard, it feeds back to the main control unit 14. The main control unit 14 sends a control command to the tailwater discharge pump 4 to pump out the upper water 8.

[0084] The main control unit 14 communicates in real time with the bidirectional pump 15, the soil pollution monitoring probe 10, and multiple pollution removal frequency testing units 11. When the soil pollution monitoring probe 10 measures that the pollutant content in the lower soil layer 9 does not meet the standard, the main control unit 14 feeds the information back to the bidirectional pump 15. The bidirectional pump 15 extracts the lower soil layer 9 from the ultrasonic generating container 7 to the test area, and uses multiple pollution removal frequency testing units 11 to redetermine the ultrasonic vibration frequency of the highly polluted mud.

[0085] like Figure 2A As shown, this embodiment provides an adaptive sludge pollutant separation method, the specific steps of which include:

[0086] 1) Optimal removal frequency test and analysis of sludge pollutants:

[0087] After the dredged sediment enters the high-pollution mud input pipe area 1, a small amount of mud is obtained through the diversion baffle 5 and enters the frequency test area. The initial optimal frequency for pollutant removal is obtained by analyzing multiple pollution removal frequency test units 11 and the main control unit 14. The signal is transmitted in real time to the ultrasonic generator container 7 through the signal transmission path 13. During ultrasonic vibration, the mud is extracted by the bidirectional pump 15 in the test area. The optimal frequency is dynamically analyzed and transmitted in real time by multiple pollution removal frequency test units 11 and the main control unit 14, so that it is dynamically adjusted to the optimal frequency for pollutant removal.

[0088] 2) Separation of sludge pollutants from soil particles:

[0089] The ultrasonic generator 7 uses the optimal frequency for contaminant removal to fully vibrate the sludge, and the soil contamination monitoring probe 10 monitors it in real time. The data is transmitted to the main control unit 14 to analyze the concentration of soil contaminants. Vibration can be stopped when the soil contaminant concentration reaches the cleanliness standard.

[0090] 3) Sludge-water separation:

[0091] After vibration is stopped, the upper water body 8 containing pollutants is pumped out through the tailwater discharge pump 4 and tailwater discharge pipe 3 for further purification treatment. With the help of the float ring 6, the pipe opening and the upper water body can be lowered synchronously until they are completely removed. The remaining lower soil body 9 can be disposed of through other means in the later stage.

[0092] 4) Feedback mechanism:

[0093] If the concentration of pollutants in the soil does not meet the standard, it will be reported to the test area, which will extract the mud from the ultrasonic generator container 7 and retest the optimal frequency.

[0094] like Figure 2B As shown in the figure, this embodiment provides a frequency testing procedure in an adaptive sludge pollutant separation method, the specific steps of which include:

[0095] 1) Initial frequency range and interval setting:

[0096] First, assume that there are 5 pollution removal frequency test units 11 (P1, P2, P3, P4, P5) in the test range. If more accurate results are desired, new pollution removal frequency test units 11 can be installed on multiple spare pollution removal frequency test unit interfaces 12. Here is an operation example: The initial frequency range is set as P1 = 40kHz, P2 = 50kHz, P3 = 60kHz, P4 = 70kHz, P5 = 80kHz, with an interval of 10kHz between each component. Assuming that the optimal frequency obtained from the initial frequency group is P5 = 80kHz, proceed to the next step: target frequency translation search, with the overall frequency shifted to the right.

[0097] 2) Target frequency translation search:

[0098] At this point, the frequency range is shifted to the right, set as P1 = 80kHz, P2 = 90kHz, P3 = 100kHz, P4 = 110kHz, P5 = 120kHz, with a 10kHz interval between each component; assuming the optimal frequency for this frequency group is P2 = 90kHz, then proceed to the next step, target frequency squeeze search.

[0099] 3) Target frequency squeeze search:

[0100] At this point, the frequency range is squeezed between 80kHz and 10kHz; P1 = 80kHz, P2 = 85kHz, P3 = 90kHz, P4 = 95kHz, P5 = 100kHz; it is assumed that the optimal frequency for this frequency group is P2 = 85kHz.

[0101] 4) Optimize the search through multiple iterations:

[0102] Based on the optimal frequency of P2 = 85kHz and the test interval of 5kHz, the frequency range is reset as follows: P1 = 80kHz, P2 = 82.5kHz, P3 = 85kHz, P4 = 87.5kHz, P5 = 90Hz. Assuming the optimal frequency is now P4 = 87.5kHz, there is no need for target frequency shifting search; the target frequency squeeze search is performed again. The number of iterations can be customized by the user to ensure the accuracy of the test results.

[0103] The adaptive sludge pollutant separation device proposed in the embodiments of the present invention uses a diversion baffle to guide a small portion of the highly polluted sludge from the input pipe into the test area, while the majority is guided into the ultrasonic generating container. The test area determines the optimal ultrasonic vibration frequency of the highly polluted sludge and transmits this frequency to the ultrasonic generating container to perform ultrasonic vibration on the highly polluted sludge. This achieves maximum separation of pollutants from soil particles in the sludge, resulting in clean soil. Compared with traditional treatment methods, this can prevent pollutant overflow during sludge reuse, which could lead to "secondary pollution".

[0104] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.

By working together with the main control unit (14), the ultrasonic generator (7) and the soil pollution monitoring probe (10), ultrasonic vibration is applied to the highly polluted mud at the optimal frequency. Once the pollutant content in the lower soil layer (9) is reduced to the cleanliness standard, ultrasonic vibration is stopped, and the upper water layer (8) containing pollutants is pumped out through the tailwater discharge pump (4) and the tailwater discharge pipe (3). When the soil pollution monitoring probe (10) measures that the pollutant content in the lower soil (9) does not meet the standard, the ultrasonic vibration frequency of the highly polluted mud is re-determined by the cooperation of the main control unit (14), the bidirectional pump (15), the ultrasonic generating container (7) and multiple pollution removal frequency testing units (11). The optimal frequency for pollutant removal in highly polluted sludge is dynamically adjusted by the coordinated operation of the main control unit (14), bidirectional pump (15), multiple pollutant removal frequency testing units (11), signal transmission path (13), and ultrasonic generator container (7). After the highly polluted mud is fed into the highly polluted mud input pipe (1), a small amount of mud is obtained through the diversion baffle (5) and enters the test area. The initial optimal ultrasonic vibration frequency for pollutant removal is obtained by analyzing the multiple pollution removal frequency test units (11) and the main control unit (14). The frequency is transmitted in real time to the ultrasonic wave generating container (7) through the signal transmission path (13) for ultrasonic vibration. During the ultrasonic vibration process, the lower soil (9) is extracted by the bidirectional pump (15) in the test area. The optimal ultrasonic vibration frequency is determined by the dynamic analysis of the lower soil using the multiple pollution removal frequency test units (11) and the main control unit (14) and transmitted in real time. The ultrasonic vibration of highly contaminated mud is carried out by the main control unit (14), the ultrasonic generating container (7) and the soil pollution monitoring probe (10) working together, using the optimal ultrasonic vibration frequency. The ultrasonic generating container (7) uses the optimal ultrasonic vibration frequency for pollutant removal to fully vibrate the highly polluted mud, and the soil pollution monitoring probe (10) monitors the pollutant concentration in the lower soil layer (9) in real time and transmits the concentration to the main control unit (14).

4. The method according to claim 3, characterized in that, The upper water body (8) containing pollutants is pumped out through the tailwater discharge pump (4) and tailwater discharge pipe (3), including: Turn on the tailwater discharge pump (4), and use the float (6) to descend synchronously with the upper water body (8) containing pollutants through the tailwater discharge pipe (3) to completely remove the upper water body (8) for subsequent purification treatment, and carry out resource-based treatment and disposal of the remaining lower soil body (9). When the soil pollution monitoring probe (10) measures that the pollutant content in the lower soil layer (9) does not meet the standard, the ultrasonic vibration frequency of the highly polluted mud is re-determined through the coordinated operation of the main control unit (14), the bidirectional pump (15), the ultrasonic generating container (7), and multiple pollution removal frequency testing units (11): When the soil pollution monitoring probe (10) measures that the pollutant content in the lower soil layer (9) does not meet the standard, the main control unit (14) feeds the information back to the bidirectional pump (15), and the bidirectional pump (15) extracts the lower soil layer (9) from the ultrasonic generating container (7) to the test area, and uses the multiple pollution removal frequency test units (11) to redetermine the ultrasonic vibration frequency of the highly polluted mud.

5. The method according to claim 3, characterized in that, The frequency adjustment methods for dynamically adjusting the optimal ultrasonic vibration frequency for pollutant removal in highly polluted slurry and for redetermining the ultrasonic vibration frequency of highly polluted slurry include: The initial frequency range and frequency interval are set according to the number of multiple pollution removal frequency test units (11), and the target frequency is tested. If the target frequency obtained from the test is outside the initial frequency range, the frequency range and frequency interval are reset to perform a target frequency translation search. If the target frequency obtained from the test is within the initial frequency range or the reset frequency range, then narrow the frequency range and frequency interval to perform a target frequency squeeze search. Based on the target frequency obtained by the target frequency squeeze search, the frequency range and frequency interval are further narrowed to perform the target frequency squeeze search. This process is repeated multiple times until the test accuracy of the target frequency is achieved.

6. The method according to claim 5, characterized in that, Based on the number of multiple pollution removal frequency test units (11), an initial frequency range and frequency interval are set, and the target frequency test is performed, including: New pollution removal frequency test units (11) are installed on multiple spare pollution removal frequency test unit interfaces (12). The initial frequency range and frequency interval are set according to the number of existing multiple pollution removal frequency test units (11) and new pollution removal frequency test units (11), and the target frequency is tested.
