Description

Technical Field

[0001] This utility model relates to the technical field of water, wastewater, sewage or sludge treatment, and in particular to an in-situ remediation device for contaminated soil and groundwater in an industrial park. Background Technology

[0002] Industrial parks are modern industrial zones that aggregate various production factors, scientifically integrate them within a certain spatial area, enhance the intensity of industrialization, highlight industrial characteristics, optimize functional layout, and ultimately become adaptable to market competition and industrial upgrading. Existing industrial parks and their enterprises cover multiple industries, including chemicals, pharmaceuticals, and metal manufacturing. While achieving rapid economic growth, these parks are also facing increasing pressure on environmental protection and management.

[0003] As more companies move into an industrial park, the problem of groundwater pollution in the area will become increasingly apparent. According to incomplete statistics, over 80% of operating industrial parks have soil and groundwater contaminated to varying degrees. However, unlike decommissioned industrial sites, the need for soil and groundwater remediation is less urgent because operating industrial parks are still in operation. Furthermore, the difficulty in tracing the source of groundwater pollution in operating industrial parks and the wide distribution of surface buildings and structures in contaminated areas also affect the remediation of contaminated groundwater. Nevertheless, with increasing emphasis on environmental protection and remediation, the remediation of soil and groundwater in operating industrial parks will inevitably become a new hotspot in the environmental remediation industry.

[0004] The current governance of industrial parks faces the following difficulties:

[0005] (1) It is difficult to trace the source of pollution in the soil and groundwater of industrial parks, so it is difficult to get the funds for remediation.

[0006] (2) Some industrial parks in operation also have hazardous materials warehouses, and various underground pipelines are intertwined, so the requirements for safe construction are high;

[0007] (3) There are many buildings on the surface of the industrial park, which limits the space for repair and construction;

[0008] These difficulties mean that traditional soil and groundwater remediation technologies and equipment cannot meet the requirements. Currently, the management of soil and groundwater in industrial parks across the country mainly adopts a phased approach, including pollution hazard investigation, sampling, risk monitoring, and early warning. The lack of relevant remediation technologies and equipment hinders the progress of remediation. Utility Model Content

[0035] The present invention will be further described in detail below with reference to the embodiments, but the protection scope of the present invention is not limited thereto.

[0036] This utility model relates to an in-situ remediation device for contaminated soil and groundwater in an industrial park. The device includes an integrated shell with several through holes, and several injection channels and several extraction channels are provided in conjunction with the through holes.

[0037] An injection configuration unit is provided in conjunction with the injection channel 1, and the injection configuration unit is connected to the injection channel 1 via an output component;

[0038] The extraction channel is equipped with a classification processing unit for sorting and processing different extracts, and the classification processing unit is configured in conjunction with the injection configuration unit;

[0039] A controller 2 is provided in conjunction with the device.

[0040] In this utility model, the outer shell includes a device cavity 3 and a control cavity 4; a partition 5 is provided between the device cavity 3 and the control cavity 4; the integrated outer shell generally includes a device cavity 3 for installing an injection channel 1, an extraction channel, an injection configuration unit, and a sorting and processing unit, and a control cavity 4 for setting a controller 2. The device cavity 3 and the control cavity 4 are separated by a partition 5 to ensure that the two cavities are relatively independent and do not affect each other.

[0041] In this invention, the injection channel 1 generally includes multiple injection ports. The outer shell can be provided with a through hole corresponding to each injection port, or an elongated through hole can be provided for all injection ports. In certain scenarios, it is necessary to ensure the sealing of the through hole. Under normal circumstances, a ball valve is used to control the liquid and / or gas output. Similarly, the extraction channel and the corresponding through hole are set up. However, the extraction channel here is divided into a water extraction channel 6 and an extraction channel 7. Due to the difference in the extracted material, they are processed by different classification and processing units.

[0042] In this invention, in practical applications, the injection channel 1 and the extraction channel are respectively located on both sides inside the outer casing, which facilitates the wiring of the pipeline.

[0043] In this invention, the positional transfer of all liquids and / or gases within the device involves the opening and closing of pipelines. Valves are installed on the pipelines, and the opening and closing of the valves, and even the direction of flow (in the case of bidirectional flow), are controlled by the controller 2. At the same time, the controller 2 also needs to control the operation of the injection channel 1, the extraction channel, the injection configuration unit, and the sorting and processing unit based on the current processing mode. The configuration of the controller 2 is easy for those skilled in the art to understand, and they can set it up according to their needs.

[0044] The injection configuration unit includes at least one mixer 8 configured in conjunction with the injection channel 1, and the mixer 8 is connected to the output end of one or more dilution tanks 9 and one or more water tanks 10 via pipelines; the water tanks 10 are configured in conjunction with the sorting and processing unit.

[0045] Each dilution tank 9 is equipped with a reflux pipeline, the two ends of which are matched with the corresponding dilution tank 9. The reflux pipeline is equipped with a centrifugal pump 14 and an electrically controlled valve 15.

[0046] The output end of any of the water tanks 10 is connected to the inlet 11 of one or more dilution tanks 9 via a water inlet pipe 12.

[0047] A liquid level sensor is provided in conjunction with either the dilution tank 9 or the water tank 10.

[0048] The injection channel 1 is also equipped with a high-pressure gas supply device 13.

[0049] In this invention, the injectable materials include, but are not limited to, water, solution, gas, and gas-liquid mixture. Therefore, at least one dilution tank 9 for outputting solution and at least one water tank 10 for outputting water are provided, and a mixer 8 is provided before outputting to the injection channel 1 for mixing water and / or solution.

[0050] Furthermore, considering the operability of gases and gas-liquid mixtures, a separate high-pressure gas supply device 13 is provided, which is directly connected to the injection channel 1 to facilitate the output of gases or gas-liquid mixtures.

[0051] In this invention, in order to facilitate the circulation and stirring of the solution in the dilution tank 9, a centrifugal pump 14 is set in conjunction with any dilution tank 9. An electrically controlled valve 15 is provided after the centrifugal pump 14. When stirring is required, the controller 2 controls the electrically controlled valve 15 to open and the centrifugal pump 14 to start. The solution in the dilution tank 9 can be returned to the dilution tank 9 through the centrifugal pump 14, the electrically controlled valve 15 and the return pipeline, so as to realize circulation and stirring.

[0052] Meanwhile, a liquid outlet valve 16 is also provided corresponding to the electrically controlled valve 15, which is connected to the mixer 8 through a pipeline. When the centrifugal pump 14 is turned off and the electrically controlled valve 15 and the liquid outlet valve 16 are opened, the solution can be output.

[0053] Water tank 10 is directly connected to mixer 8 via centrifugal pump 14 and corresponding electrically controlled valve.

[0054] In practical applications, to facilitate solution preparation, the output end of the water tank 10 is connected to the inlet 11 of one or more dilution tanks 9 via a water inlet pipe 12. This allows the solution to be prepared using the clean water in the water tank 10, thus eliminating the need for external water supply to some extent. Simultaneously, to add water to the dilution tanks 9, a corresponding power component is installed on the output pipeline of the water tank 10, such as a centrifugal pump 26 to output clean water, and corresponding valves are installed on the pipeline, typically electrically controlled valves, which are easily understood by those skilled in the art. Those skilled in the art can set them up according to their needs. The same applies to other pipelines in the device.

[0055] Furthermore, the water tank 10 is also configured in conjunction with the sorting and treatment unit via a branch pipe 17, for outputting clean water to the sorting and treatment unit or receiving clean water returned from the sorting and treatment unit.

[0056] During the configuration process, level sensors in dilution tank 9 and water tank 10 are essential, especially the level sensor in water tank 10. If necessary, an online sampling mechanism should be installed at the output of injection channel 1 to sample and quickly test the prepared solution. If the solution test results do not meet the actual injection requirements, controller 2 controls water tank 10 and dilution tank 9 to coordinate and reconfigure the reagent. Generally, when the injection volume is large, a higher concentration of reagent can be prepared. By simultaneously injecting clean water, the final reagent concentration injected underground reaches the design value, while also achieving a larger injection volume. By reasonably collecting the level information returned by the level sensor, the current water storage volume can be determined, allowing for the selection of whether to connect to a water source, or to collect clean water returned from the classification and treatment unit for injection. The level sensor in dilution tank 9 is used to guide whether further reagent reconfiguration is needed.

[0057] The extraction channel includes a water pumping channel 6 and an extraction channel 7. The classification and processing unit includes a gas-liquid separation component 18 that works in conjunction with the extraction channel 7 and water quality monitoring devices 19 that work in conjunction with the liquid output end of the gas-liquid separation component 18 and the water pumping channel 6, respectively. A gas processing mechanism 20 is provided at the gas output end that works in conjunction with the gas-liquid separation component 18. An output pipe 21 is connected to the two water quality monitoring devices 19. An exhaust gas treatment device 22 is provided in conjunction with the gas processing mechanism 20.

[0058] A branch pipe 17 is provided at the output pipe 21, and the branch pipe 17 is configured in conjunction with the injection configuration unit.

[0059] In this utility model, the extraction channel includes a water pumping channel 6 and an extraction channel 7, which are used to extract groundwater and a mixture of polluted water and soil gas, respectively. Here, the water pumping channel 6 can be equipped with a self-priming pump 23, while the extraction channel 7 requires the use of a jet pump 24 for extraction.

[0060] Corresponding to the extraction channel 7, the classification and processing unit includes a gas-liquid separation component 18, and its end is respectively equipped with a gas processing mechanism 20 for processing soil gas and a water quality monitoring device 19 for monitoring the polluted water.

[0061] Corresponding to the pumping channel 6, the classification and treatment unit includes another water quality monitoring device 19 for monitoring the polluted water. In practical applications, the two water quality monitoring devices 19 can be integrated into one.

[0062] In this invention, a water quality monitoring device 19 is used to detect the concentration of pollutants in the extracted groundwater, and based on this, different output directions of the extracted groundwater are achieved, including but not limited to wastewater treatment devices or piped systems.

[0063] Furthermore, a branch pipe 17 is set at the output pipe 21. The two-way valve 25 set on the branch pipe 17 is connected to the injection configuration unit. To be precise, it is connected to the water tank 10, so that the treated or collected water that meets the requirements can be returned to the water tank 10 when the controller 2 prompts that the water volume in the water tank 10 is insufficient to perform subsequent operations, so as to achieve reuse.

[0064] Gas detection equipment is configured in the gas processing unit 20. Based on the detection results, the soil gas is processed by the exhaust gas treatment device 22 and output after meeting the standards.

[0065] The following is a description of the specific implementation process of the repair work using this utility model. This is only an application example of this utility model, and this utility model does not protect the specific application and method.

[0066] It should be noted that in the specific implementation of this utility model, the extraction-disposal, two-phase extraction and microbial treatment technologies can be carried out independently, in combination, or in any combination of two of them, and there is no necessary sequential relationship between them.

[0067] The in-situ remediation device for contaminated soil and groundwater in industrial parks of this invention can be applied to groundwater monitoring and real-time treatment (extraction), two-phase extraction treatment of contaminated sites, and injection treatment of contaminated sites.

[0068] In this invention, pollutants in the soil and groundwater of industrial parks are mainly classified into two categories: heavy metals and organic pollutants. In-situ remediation technologies for heavy metal-contaminated soil and groundwater primarily include extraction-disposal and electrokinetic remediation. In-situ remediation technologies for organic-contaminated soil and groundwater primarily include biphasic extraction, chemical oxidation, thermal desorption, and microbial remediation. Considering the low efficiency and high energy consumption of electrokinetic remediation, and its limited application, and the fact that chemical oxidation requires injecting oxidants underground, which can corrode underground metal storage tanks, pipelines, and building foundations, it is not suitable for industrial parks. Thermal desorption technology is also energy-intensive and can damage underground storage tanks and pipelines during the heating process, making it unsuitable for industrial parks as well. Therefore, the technologies suitable for remediating contaminated soil and groundwater in industrial parks are primarily extraction-disposal, biphasic extraction, and microbial treatment technologies.

[0069] Based on the preliminary investigation results of the industrial park in operation, groundwater monitoring and real-time treatment were applied. Self-priming pump 23 was used to centrally extract groundwater with high concentration or heavy metal pollution. On the one hand, this quickly reduced the groundwater pollution load, and on the other hand, it prevented the spread of high-concentration polluted groundwater and increased the pollution range.

[0070] Subsequently, a two-phase extraction treatment was applied to the contaminated site, using jet pump 24 to extract groundwater and soil gas from the contaminated area, further reducing organic pollutants in the soil and groundwater and controlling the disorderly diffusion of volatile organic compounds.

[0071] Finally, the contaminated site needs to be treated with injection. For organic pollutants remaining in the soil that are not easily removed by physical means, treatment methods including but not limited to injecting bacterial agents and solutions are used. Gravity is used to distribute the bacterial agents evenly in the vadose zone and saturation layer. Two-phase extraction is used regularly to increase the oxygen content in the soil atmosphere, improve the living environment of microorganisms, and enhance the degradation effect of microorganisms on organic pollutants.

[0072] In the groundwater monitoring and real-time processing, polluted water in the groundwater extraction well is extracted through the pumping channel 6 of the extraction channel. The system monitors the water and selects whether to connect the injection configuration unit and determine the output channel based on the monitoring results, until the pollutant concentration in the polluted water drops to a preset value and then stops.

[0073] Specifically, the groundwater monitoring and real-time treatment process involves an extraction-treatment operation, which connects the pumping channel 6 to the groundwater extraction well via a pipeline; the self-priming pump 23 is turned on to extract polluted groundwater, and the extracted groundwater is monitored online using the water quality monitoring equipment 19. When the groundwater pollution is severe, it is transmitted to a wastewater treatment device or discharged into the sewer system through the output pipe 21; when the degree of water pollution decreases to a certain level, pumping is stopped.

[0074] In the two-phase extraction treatment of the contaminated site, the contaminated water and soil gas in the groundwater extraction well are extracted through the extraction channel 7 of the extraction channel. The extracted contaminated water and soil gas are separated and treated separately by the classification and treatment unit until the pollutant concentration of the contaminated water and soil gas drops to the preset value and then the machine is shut down.

[0075] In the specific implementation process, when performing two-phase extraction, the extraction channel 7 is connected to the groundwater extraction well through a pipeline, the jet pump 24 is turned on, and the mixture of polluted water and soil gas is extracted. The extracted wastewater and waste gas are separated by the gas-liquid separation component 18. The separated wastewater is monitored online using the water quality monitoring equipment 19. For groundwater exceeding the standard, it is transmitted to the wastewater treatment device or discharged into the sewer through the output pipe 21. For groundwater that meets the standard, it can be connected to the channel of the water tank 10 and reused for diluting the reagents or bacterial agents. The gas treatment mechanism 20 and the tail gas treatment device 22 are used to monitor and treat the separated waste gas. The gas that meets the standard is discharged into the atmosphere. When the water quality and tail gas pollution concentrations drop to a certain level, the two-phase extraction is stopped.

[0076] The injection treatment of the contaminated site includes injecting bacterial agents and / or prepared solutions, and injecting high-pressure gas;

[0077] The corresponding bacterial agent and / or solution and / or high-pressure gas are prepared using the injection configuration unit and injected into the preset position through injection channel 1.

[0078] In this invention, in the later stage of biphasic extraction or other applicable scenarios, it is necessary to inject bacterial agents and / or solutions and / or gases and / or gas-liquid mixtures into the contaminated area. Taking the injection of bacterial agents for microbial degradation in the later stage of biphasic extraction as an example, bacterial agents or nutrient solutions can be injected separately, or bacterial agents and nutrient solutions can be injected simultaneously. The specific implementation can be carried out according to the needs of each monitoring well on site.

[0079] When injecting only a single liquid, the two dilution tanks 9 can be used alternately to avoid the waiting period for drug preparation. For one type of liquid, the bacterial agent or nutrient solution is added into the dilution tank 9 through the inlet 11, and the clean water in the water tank 10 is injected into the dilution tank 9. At the same time, the centrifugal pump 14 and the electrically controlled valve 15 are started to circulate internally and mix the liquid in the dilution tank 9. After the liquid in the dilution tank 9 is mixed evenly, the electrically controlled valve 15 and the liquid outlet valve 16 are started to output the liquid and inject it into the ground through the injection channel 1.

[0080] When it is necessary to inject bacterial agent and nutrient solution at the same time, after diluting the two agents separately, start the corresponding pipeline, mix the two liquids through mixer 8 and inject them into the ground. When the injection volume is large, a higher concentration of agent can be prepared. By simultaneously injecting clean water, the final concentration of agent injected into the ground can reach the design value, while also achieving a larger injection volume.

[0081] When the dissolved oxygen content in the groundwater is low, affecting the remediation effect of aerobic degrading bacteria, the high-pressure gas supply equipment 13 is activated to inject high-pressure gas into the injection well through the injection channel 1 to aerate the groundwater.

[0082] This utility model also relates to the collaborative management of controller 2, including:

[0083] When extracting clean water from water tank 10, the process includes, but is not limited to, preparing reagents and directly outputting clean water, obtaining liquid level information from the liquid level sensor, calculating the flow rate, and performing the operation of filling water tank 10 with an external water source based on the flow rate and the expected water volume. In practical applications, when the extracted groundwater meets the configuration requirements, it can also flow back to water tank 10 from branch pipe 17.

[0084] Furthermore, when the previous operation is being performed, the next process enters the preparation state. Especially in the later stage of biphasic extraction, it is necessary to control the process with controller 2 to promptly prepare one or more bacterial agents and / or solutions, and to output the results as soon as possible with controller 2.

[0085] This invention provides an embodiment of a utility model in application. A field test was conducted in an industrial park in Zhejiang Province. The groundwater in the test area exceeded pollution standards, with vinyl chloride and toluene as the characteristic pollutants. The initial concentrations of vinyl chloride were 152 µg / L to 463 µg / L, and the initial concentrations of toluene were 2.51 mg / L to 10.3 mg / L. For monitoring wells with high concentrations, a 5-day extraction-treatment process reduced vinyl chloride concentration to 135 µg / L~276 µg / L and toluene concentration to 2.23 mg / L~6.28 mg / L. A 14-day two-phase extraction treatment further reduced vinyl chloride concentration to 89.5 µg / L~143 µg / L and toluene concentration to 1.79 mg / L~3.16 mg / L. Finally, three rounds of injection of degrading bacteria selected and domesticated from local groundwater were administered, one injection every 7 days. After these three rounds, vinyl chloride concentration decreased to 36.5 µg / L~49.2 µg / L and toluene concentration decreased to 0.573 mg / L~1.14 mg / L, meeting the relevant standards.

[0086] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
