Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of groundwater treatment, in particular to a groundwater treatment system, method and computer equipment. BACKGROUND

[0002] With the development of urbanization and industrialization, groundwater pollution problems are widespread. Groundwater pollution is difficult to control and treat due to its concealment, complexity, and characteristics, and the cost of groundwater treatment and remediation is huge. Therefore, once groundwater is polluted, it is very difficult to treat and restore. The groundwater pollution treatment of operating enterprises is particularly special and difficult. For example, groundwater remediation construction intersects with the operation of operating enterprises, and the connection between the two is difficult. Long-term construction will seriously affect the normal production of enterprises and even bring negative effects.

[0003] In the prior art, groundwater treatment usually adopts extraction treatment technology, permeable reactive barrier, in-situ chemical oxidation / reduction, monitoring natural attenuation, in-situ bioremediation, and phytoremediation.

[0004] For example, the patent with publication number CN106277386A relates to a circulating controllable groundwater pollution multi-stage enhanced remediation system, which is composed of a water pumping unit, a water injection well group, a pollution multi-stage enhanced treatment unit, and an automatic control device. The automatic control device can automatically control the water pumping switch or the water pumping rate according to the changes in water level and water quality. However, when used in operating enterprises, the system adopts an extraction-injection combined remediation process, but it is difficult to adjust the hydraulic gradient according to the dynamic of the pollution plume.

[0005] The patent with publication number CN111003792A relates to an intelligent in-situ groundwater remediation method, which includes an in-situ oxidation system, a circulating extraction system, and a monitoring system. The method combines in-situ oxidation technology with circulating extraction technology, but lacks a water treatment system. The contaminated groundwater in the extraction well is directly extracted into the water injection well, which cannot determine the oxidation effect and has the risk of secondary pollution. SUMMARY

[0053] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0054] To solve the technical problems mentioned in the background art, the embodiments of the present application provide a groundwater treatment system, which is specifically described as follows Figure 1 As shown in the figure, the system comprises at least one detection device 101, at least one pumping and injection integrated well 102, and a controller 103, wherein the at least one pumping and injection integrated well 102 is arranged at the boundary of the groundwater pollution plume, and the detection device 101 corresponds to the pumping and injection integrated well 102 one by one.

[0055] The first detection device 101 is configured to periodically detect water sample data in the corresponding first pumping and injection integrated well 102 and send the water sample data to the controller 103.

[0056] The first pumping and injection integrated well 102 is any one of the plurality of pumping and injection integrated wells 102, and the first detection device 101 is any one of the plurality of detection devices 101.

[0057] The controller 103 is configured to determine the sewage concentration in the first pumping and injection integrated well 102 according to the water sample data, determine the first groundwater pollution plume according to the sewage concentration, and determine the pumping and injection mode of the first pumping well according to the first groundwater pollution plume.

[0058] Exemplarily, the groundwater treatment system of the present application can be applied to groundwater treatment under any scene and condition. In the embodiments of the present application, the groundwater treatment of a production enterprise (an enterprise in production) is taken as an example for introduction.

[0059] Firstly, the layout process of the groundwater system of the production enterprise is introduced. The groundwater pollution treatment of the production enterprise has particularity and difficulty, such as the intersection of groundwater remediation construction and production enterprise operation, the difficulty of connection between the two parties, the serious influence of long-time construction on normal production of the enterprise, and even the negative influence. Therefore, when the groundwater system is laid out, the planar distribution map of the production enterprise is first obtained to determine the construction position, and the pre-obtained groundwater pollution plume of the production enterprise is combined to determine the layout position of the pumping and injection integrated well 102.

[0060] The pumping and injection integrated well 102 is arranged at the periphery of the groundwater pollution plume, and can complete the extraction and purification of the groundwater sewage and flushing according to the actual pollution plume. For example Figure 2 As shown in the figure, it is a planar distribution map corresponding to the production enterprise, and a layout schematic diagram of the pollution plume and the pumping and injection integrated well 102 (pumping and injection system) corresponding to the production enterprise in the embodiments of the present application.

[0061] The pumping and injection integrated well 102 is arranged at the boundary of the pollution plume, and the treatment condition of the groundwater can be accurately obtained from the water sample in the pumping and injection integrated well 102. Therefore, the detection device 101 is further arranged for each pumping and injection integrated well 102 to periodically obtain the water sample data in the pumping and injection integrated well 102, so that real-time detection of the groundwater treatment process can be achieved.

[0062] The first detection device 101 can be a corresponding sewage concentration detector. After the first detection device 101 obtains the water sample data corresponding to the pumping and injection integrated well 102, the water sample data is sent to the controller 103. The controller 103 can further analyze the water sample data, for example, dynamically adjusting the method of groundwater treatment according to the change of the water sample data.

[0063] In the embodiment, the pumping and injection mode of the pumping and injection integrated well 102 can be determined according to the sewage concentration in the water sample data. For example, when the sewage concentration of the water sample data is greater than a certain value, it indicates that the pollution degree of the groundwater is high, and the groundwater needs to be purified. Therefore, the pumping and injection integrated well 102 needs to be switched to the pumping mode to pump the groundwater, and the pumped groundwater needs to be purified subsequently. When the sewage concentration of the water sample data is less than the corresponding value, it indicates that the pollution degree of the groundwater is not high and the groundwater can be purified through the natural infiltration process. Therefore, the pumping and injection integrated well 102 can be switched to the injection mode to further accelerate the natural infiltration purification of the sewage. When the injection is performed, the previously purified groundwater can be used for injection to complete the flushing of the pollution plume.

[0064] Of course, to achieve the above functions, the pumping and injection integrated well 102 can be adaptively provided with a pumping system, an injection system, a pumping pipe, an injection pipe, and a corresponding booster pump.

[0065] On the basis of the above embodiment, the embodiment of the application further provides another groundwater treatment system. The system further includes a collection device, which includes a first collection sub-device and a second collection sub-device. A baffle is arranged between the first collection sub-device and the second collection sub-device.

[0066] The first collection sub-device is used to store the groundwater in the first pumping and injection integrated well 102.

[0067] The second collection sub-device is used to deliver the treated groundwater in the first pumping and injection integrated well 102 to the first pumping and injection integrated well 102 again.

[0068] Exemplarily, in the process of treating the groundwater, the purification treatment of the groundwater is involved. Therefore, the groundwater treatment system further includes a collection device, which can be used for the storage of the sewage in the groundwater and the storage of the purified water. In order to further prevent the purified water from being secondarily polluted by the sewage, a baffle is arranged between the two collection sub-devices to separate them.

[0069] Corresponding to the process of purifying the groundwater, the system further includes a water treatment device, which includes a three-stage sedimentation tank, a flocculation sedimentation tank, a chemical oxidation tank, an adsorption tank, and a clear water tank.

[0070] The water treatment device is used for purifying the underground water in the first collecting sub-device, and the underground water in the first collecting sub-device is stored in a clear water tank after passing through a three-stage sedimentation tank, a flocculation sedimentation tank, a chemical oxidation tank and an adsorption tank. The second collecting sub-device is used for injecting the underground water in the clear water tank into the first pumping and injecting integrated well 102.

[0071] To further optimize the underground water treatment system, in a preferred embodiment, the system further comprises a pressure sensor located at the bottom of the first pumping and injecting integrated well 102.

[0072] The pressure sensor is used for acquiring first water level information of the first pumping and injecting integrated well 102.

[0073] When the first water level information of the first pumping and injecting integrated well 102 is less than a first threshold value, a stop pumping instruction is sent to the controller 103, so that the controller 103 controls the first pumping and injecting integrated well 102 to stop pumping the underground water to the first collecting sub-device, so as to prevent the motor from being burnt out.

[0074] When the first water level information is greater than a second threshold value, a pumping instruction is sent to the controller 103, so that the controller 103 controls the first pumping and injecting integrated well 102 to pump the underground water in the first pumping and injecting integrated well 102 to the first collecting sub-device.

[0075] Exemplarily, to treat the underground water in the pumping and injecting integrated well 102 in time, a pressure sensor is arranged at the bottom of each pumping and injecting integrated well 102. According to the real-time test of the water level information in the pumping and injecting integrated well 102 by the pressure sensor, when the water level in the pumping and injecting integrated well 102 is too low, the pumping of the underground water in the well can be stopped, so as to prevent the motor from being burnt out. Similarly, to prevent the underground water in the pumping and injecting integrated well 102 from overflowing, when the water level information is greater than the second threshold value, the water in the pumping and injecting integrated well 102 is pumped to the first collecting sub-device. The first threshold value and the second threshold value here can be a percentage of the volume of the corresponding pumping and injecting integrated well or the corresponding collecting device.

[0076] In another preferred embodiment, the pressure sensor is also located at the bottom of the second collecting sub-device.

[0077] The pressure sensor is also used for acquiring second water level information of the second collecting sub-device.

[0078] When the second water level information is greater than the second threshold value, a water injection instruction is sent to the controller 103, so that the controller 103 controls the first pumping and injecting integrated well 102 to inject the underground water in the second collecting sub-device into the first pumping and injecting integrated well 102.

[0079] Exemplarily, the groundwater is treated in time, so when the water level information in the second collecting sub-device is greater than the second threshold value, the injection into the pumping and injection integrated well 102 in the second collecting sub-device is in time to prevent overflow, and the flushing of the groundwater pollution plume is completed.

[0080] According to the above embodiment, the groundwater treatment system is summarized with a specific example, as shown in Figure 3 It is shown that a kind of in production enterprise pollution groundwater treatment system principle schematic diagram, Figure 3 In the embodiment, first, the pumping and injection integrated well 102 extracts groundwater, and the booster pump 5 is powered, the water in the pumping and injection integrated well 102 is pumped up, and is transported to the first collecting sub-device 10 through the water delivery pipe 6. When the water level in the pumping and injection integrated well 102 drops to the bottom, the pressure sensor 4 receives a signal, and the signal is transmitted to the controller 103, and the controller 103 is connected with the booster pump 5 switch, and the booster pump 5 is automatically turned off. Wherein, the water delivery pipe is PE material.

[0081] The water level in the first collecting sub-device 10 rises to a certain height, the pressure sensor 4 in the first collecting sub-device receives a signal, and the signal is transmitted to the controller 103, and the controller 103 connected with the first collecting sub-device opens the control switch, and the booster pump 5 starts to run, and the contaminated groundwater in the first collecting sub-device is extracted to the water treatment system 12 for treatment. The water treatment system includes three-stage sedimentation, flocculation sedimentation, chemical oxidation and activated carbon adsorption functions, and can treat heavy metal and organic contaminated groundwater.

[0082] The water treated by the water treatment system 12 is detected, and after reaching the standard, it is injected into the second collecting sub-device 9. When the water level in the second collecting sub-device 9 rises to a certain height, the pressure sensor 4 in the second collecting sub-device 9 receives a signal, and the signal is transmitted to the controller 103, and the controller 103 connected with the second collecting sub-device 9 opens the control switch, and the booster pump 5 starts to run, and the clean water is automatically injected into the pumping and injection integrated well 102 through the water injection pipe 13, to form a precipitation funnel and accelerate the renewal of groundwater in the stratum.

[0083] Periodically, groundwater monitoring data is collected in the monitoring system 14, and the pollution plume is updated through simulation software. According to the updated pollution plume, the pumping and injection integrated well 102 function is re-laid, and the next step is run, or the groundwater concentration in the pumping and injection integrated well 102 is periodically monitored, and the pumping and injection mode of the pumping and injection integrated well 102 is controlled according to the groundwater concentration.

[0084] By setting the groundwater treatment system, at least one detection device, at least one pumping and injection integrated well and the controller, at least one pumping and injection integrated well is arranged at the boundary of the pollution plume of groundwater, which can better detect and clean the pollution of groundwater; further, each pumping and injection integrated well corresponds to the corresponding detection device one by one, which is more conducive to the detection device to obtain the water sample in the pumping and injection integrated well, and the arrangement of the pumping and injection integrated well reduces the system layout process and reduces the space occupation; the first detection device periodically detects the water sample data in the corresponding first pumping and injection integrated well, and sends the water sample data to the controller, and the controller can flexibly control the pumping and injection mode of the pumping and injection integrated well according to the water sample data, so as to realize the purification and flushing of the groundwater, thereby realizing the flexible treatment of the groundwater.
