Description

Technical Field

[0001] The present invention relates to the technical field of groundwater pollution control and restoration, and in particular to an integrated restoration system based on groundwater air disturbance. Background Art

[0002] Volatile organic pollutants (VOCs) are characteristic pollutants in oil-contaminated sites. They often have "three-hazard" effects. Once they enter the underground environment, they can remain for years, decades or even longer, seriously endangering public health and ecological security. They have become an important issue restricting the rapid development of social economy. Therefore, the related groundwater and soil pollution problems need to be solved urgently.

[0003] At present, the commonly used groundwater pollution remediation technologies include in-situ reaction zone remediation technology, in-situ chemical oxidation technology, in-situ microbial remediation technology, in-situ air disturbance technology (AS), etc. These technologies all remove pollutants by injecting oxidants, reductants, microorganisms or air into the ground. The above technologies all require the establishment of injection wells, and the agent injection wells often use high-pressure injection. The injected agent gradually covers the entire contaminated area under the action of lateral and longitudinal diffusion, and achieves the remediation effect after contacting and reacting with the pollutants. Since the injection well is fixed in position and the injected agent usually migrates laterally and vertically in a free diffusion manner, it is often necessary to design many injection wells in actual site remediation, resulting in increased remediation costs and possible formation damage.

[0004] In-situ air disturbance technology (AS technology) injects air into the underground environment. The air flow ring moves upward due to buoyancy, and uses gas-liquid mass transfer to carry pollutants to the surface for subsequent treatment. Therefore, AS technology is considered to be one of the most effective methods for removing volatile organic pollutants (VOCs) in soil and groundwater. The advantages of AS technology include simple equipment, easy installation and operation, little disturbance to the site, and low treatment costs. However, this technology can only remove VOCs through physical volatilization, and it is difficult to effectively degrade substances such as SVOCs, heavy metals, and new pollutants.

[0005] In summary, how to reduce the number of reagent injection wells, increase the reagent transmission distance and expand the scope of pollutant remediation using AS technology, thereby reducing the remediation cost and reducing damage to the formation, is a technical bottleneck problem that groundwater pollution remediation needs to face in the long term.

The second permeable section discharges into the external groundwater and disturbs it, so that the two cooperate to form a hydraulic circulation 30. In this embodiment, the diameter of the gas injection pipe 6 is 3 cm, and the aeration head at the bottom of the gas injection pipe 6 is composed of a one-way air valve and a ten-mesh quartz sand bubble stone to ensure the outflow gas rate. At the same time, the position of the water-permeable and air-impermeable membrane 8 is flush with the bottom of the gas injection pipe 6, and the thickness of the water-permeable and air-impermeable membrane 8 is not less than 3 cm, ensuring that the airflow area 29 or the repair agent can migrate from the aeration head to the surroundings. A pressure-stabilizing valve 2 and / or a first flow sensor 3 and / or a first pressure sensor 4 are also installed on the pipeline between the air compressor 1 and the gas injection pipe 6.

[0030] The reagent injection mechanism includes a reagent preparation box 9, an injection pump 10 and a reagent injection pipe 13. The input end of the injection pump 10 is connected to the reagent preparation box 9, and the output end of the injection pump 10 is connected to one end of the reagent injection pipe 13. The other end of the reagent injection pipe 13 is arranged in the aeration well pipe. The other end of the reagent injection pipe 13 is arranged below the water level and above the water-permeable and air-tight membrane 8. In this embodiment, the diameter of the reagent injection pipe 13 is 2 cm, and a second flow sensor 11 is arranged on the reagent injection pipe 13, and a second valve 12 is installed on the reagent injection pipe 13.

[0031] At the same time, in another embodiment, the gas injection pipe 6 can also be used for agent injection. In the actual site, the gas injection pipe 6 can be used for agent injection first and then aeration, or agent injection and aeration can be performed simultaneously. The bottom end of the gas injection pipe 6 goes deep into the bottom of the aeration well pipe. The aeration head at the bottom of the gas injection pipe 6 can prevent groundwater from flowing back into the gas injection pipe 6, while ensuring that the aperture of the aeration head is within a certain range, so as to enhance the hydraulic circulation 30 effect with as many air flow area 29 channels as possible;

[0032] A baffle 14 is provided in the aeration well pipe for raising the water level in the aeration well pipe and strengthening the hydraulic circulation 30. The baffle 14 includes a plate body, and a sieve hole is provided above the plate body for ensuring that the raised water level passes through and forms a circulation with the groundwater in the aeration well pipe. Several baffles 14 are evenly distributed between the gas injection pipe 6 and the aeration well pipe. The top of the baffle 14 is kept at a distance from the upper end of the aeration well pipe, and the bottom of the baffle 14 extends into the groundwater. The spacing between the baffles 14 should not be too large to ensure that the groundwater level is raised. At the same time, large-particle media can be filled between the baffles 14 as needed to further strengthen the raising of the groundwater level. The length of the lower part of the baffle 14 is not less than 50 cm and is impermeable. A sieve hole for water permeability is designed at the upper part of the baffle 14.

[0033] In this embodiment, the diameter of the aeration well pipe is not less than 15 cm. The aeration well pipe includes a steel pipe. The outer side of the steel pipe is located in the first impermeable section and the second impermeable section and is filled with solid low-permeability filler 17, which is specifically filled with clay or / and concrete medium with fine particle size. The filling height is above 10 cm, which can not only ensure the stability of the filler, but also prevent the outflowing gas or repair agent from forming a dominant flow in the filler area, and also play a role in fixing the aeration well pipe. The outer side of the steel pipe is located in the first permeable section and the second permeable section and is filled with gravel river sand and / or gravel with appropriate particle size distribution. Quartz sand medium, the steel pipe is located in the first permeable section and the second permeable section and is filled with permeable holes. The aeration well pipe is driven into the ground, and the top of the aeration well pipe is higher than the groundwater level. The permeable holes below the water level allow water to flow into the aeration well pipe. The bottom of the aeration well pipe is located at the bottom of the contaminated groundwater. The outside of the aeration well pipe corresponds to the position of the permeable holes and needs to be covered with a stainless steel mesh, and then filled with permeable filler 16 and impermeable filler 15 to achieve both permeability and filtering effects. No related fillers are required in the aeration well pipe to prevent affecting the hydraulic circulation 30 effect.

[0034] The repair system also includes a monitoring unit and a remote central control unit. The monitoring unit is used to observe, record and organize the dynamic elements of groundwater in the aeration well pipe. The injection unit, the tail gas collection unit and the monitoring unit are respectively connected to the remote central control unit by signal. The monitoring unit includes a monitoring probe 27 and a monitoring well pipe 28. The monitoring probe 27 is connected to the transmitter 25 through a monitoring cable 26. The monitoring probe 27 is arranged in the monitoring well pipe 28. One end of the monitoring well pipe 28 passes through the water-permeable and air-impermeable membrane 8 and is located below it. The height of the monitoring instrument probe 27 can be adjusted according to actual needs to ensure real-time monitoring of the dynamic elements of groundwater. The monitoring probe 27 is located below the water level. The remote central control unit includes a single-chip microcomputer, which is provided with a GPS module. The single-chip microcomputer is respectively connected to the injection unit, the tail gas collection unit and the monitoring unit by signal. In this embodiment, a monitoring well pipe 28 is provided with a diameter of 3 cm, the bottom of which is blocked, and holes are opened at intervals from the bottom to the top. The length of the opening is from the bottom of the monitoring well pipe 28 to the groundwater level, and it is installed on the inner side of the aeration well. 。

[0035] The exhaust gas collection unit includes an exhaust pump 21, a polluted gas reagent reaction box 22, an activated carbon adsorption column 23 and an exhaust gas recovery pipe 24. One end of the exhaust gas recovery pipe 24 is arranged underground and above the water level, and the other end of the exhaust gas recovery pipe 24 is connected to the input end of the exhaust pump 21, and the output end of the exhaust pump 21 is connected to the input end of the polluted gas reagent reaction box 22, and the output end of the polluted gas reagent reaction box 22 is connected to the activated carbon adsorption column 23. A second pressure sensor 20, a third flow sensor 19 and a third valve 18 are installed on the exhaust gas recovery pipe 24.

[0036] When the above-mentioned integrated remediation system based on groundwater air disturbance is in use, the air compressor 1 of the injection unit can select the working mode of the air compressor 1 as pulse aeration or continuous aeration according to the needs during the groundwater air disturbance process, so as to drive the circulation of groundwater, so that the airflow zone 29 and the hydraulic circulation 30 carry the remediation agent together and evenly disperse it in the aquifer, increase the contact probability between the agent and the pollutants, and thus improve the pollutant removal effect. When the air compressor 1 is not running, the agent injection and groundwater monitoring functions are still retained, and clean air is injected into the aeration well pipe, thereby providing driving force for the groundwater to form a hydraulic circulation 30, so that the airflow zone 29 and the hydraulic circulation 30 carry the remediation agent together and evenly disperse it in the aquifer, and increase the contact probability between the agent and the pollutants. When using the air compressor 1 to transport gas to the aeration well unit, it is necessary to consider the stability of the air pressure, the gas injection flow rate, and the underground Parameters such as water flow rate and aeration method are important factors that affect whether groundwater can form circulation. If the gas injection flow rate is small, it is not easy to form a hydraulic circulation 30 effect in the aquifer; if the gas injection flow rate is too large, the increase in the radius of the hydraulic circulation 30 is not obvious, which increases the repair cost. The injection unit realizes the stable and continuous injection of gas through the gas regulating valve, which provides a guarantee for the formation of a stable hydraulic radius of the groundwater aeration well technology, and in the actual site, the gas injection unit can also inject repair agents, specifically, injecting the repair agents into the gas injection pipe 6, and then aerating, or injecting the agents and aerating at the same time. The monitoring device composed of the first flow sensor 3 or the first pressure sensor 4 is connected to the remote central control unit, which is not shown in the figure. The remote central control unit adjusts the operating parameters such as the gas injection flow and pressure of the air compressor 1 according to the detection signal;

[0037] The exhaust pump 21 of the exhaust gas collection unit extracts the gas containing pollutants to the ground for treatment through the exhaust gas recovery pipe 24. The outlet of the exhaust pump 21 is connected to the polluted gas reagent reaction box 22 and the activated carbon adsorption column 23 in sequence through pipelines. Bacterial strains are placed in the reagent reaction box.
