Description

Technical Field

[0001] The invention relates to the technical field of decomposition of organic sewage, in particular to a device for treating organic pollution in groundwater. Background Art

[0002] Chlorinated hydrocarbons are organic pollutants in the groundwater environment, and the pollution is more serious in chemical enterprise areas. Chlorinated hydrocarbons are heavy organic pollutants. Since chlorinated hydrocarbons are heavy pollutants, in the groundwater pollution environment, the pollutants are usually deposited at the bottom of the aquifer.

[0003] Since these pollutants are usually deposited at the bottom of the aquifer, it is necessary to consider that the vertical hydraulic recharge is often greater than the lateral hydraulic recharge when performing extraction treatment, which directly affects the effect of extraction treatment. What is more difficult is that when trying to enhance the treatment effect by injecting a large amount of drugs, it is often encountered that a large amount of injection cannot be injected, resulting in overflow of the drug slurry, further reducing the treatment efficiency. In order to solve this problem, the sewage is extracted and decomposed. However, when the sewage is extracted, the heavy pollutants in the sewage will be deposited at the bottom of the water layer. When the sewage is extracted, the heavy pollutants in the sewage are easily redistributed due to disturbance during the extraction process, resulting in some sewage that is not deposited at the bottom being extracted. This not only increases the difficulty of subsequent treatment, but also increases the amount of drugs used due to uneven concentrations of pollutants when the sewage reacts with the drug.

[0004] In addition, during the sewage treatment process, when sewage reacts with drugs, gases will inevitably be produced. If these gases are not discharged or collected in time, they will be stored in the groundwater in the form of bubbles. This phenomenon not only reduces the effective contact area between the drug and sewage, thereby reducing the reaction efficiency, but also affects the overall effect of activation and degradation. What is more serious is that if these decomposition gases are directly discharged into the air without treatment, it will undoubtedly cause additional pressure on the environment.

[0005] Therefore, a groundwater organic pollution treatment device is proposed to solve the above problems. Summary of the invention

After stratification, the sewage with higher concentration at the bottom of the circulating sewage well can flow into the water injection decomposition well through the sewage discharge pipe at the bottom of the circulating sewage well for mixing, so that the pollutants with more concentrated concentrations can be extracted in a targeted manner, thereby improving the flow supply of heavy organic pollutants at the bottom of the circulating sewage well.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0041] Example

[0042] Please refer to Figures 1 to 7 As shown:

[0043] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a groundwater organic pollution treatment device, including a circulating sewage well 1, a water injection decomposition well 11 is arranged on one side of the circulating sewage well 1, the circulating sewage well 1 is arranged circumferentially outside the water injection decomposition well 11, a dosing mixing box 12 is arranged on one side of the water injection decomposition well 11, a sightseeing ladder 13 is arranged on the side of the circulating sewage well 1 away from the water injection decomposition well 11, and also includes a layered sewage extraction mechanism 2 and a constant pressure gas collection mechanism 3;

[0044] Layered sewage extraction mechanism 2;

[0045] The stratified sewage pumping mechanism 2 is arranged in the circulating sewage well 1, and the stratified sewage pumping mechanism 2 is used for stratifying the sewage in the circulating sewage well 1;

[0046] Constant pressure gas collecting mechanism 3;

[0047] The constant pressure gas collection mechanism 3 is arranged in the water injection and decomposition well 11, and the constant pressure gas collection mechanism 3 is used to collect the gas in the water injection and decomposition well 11;

[0048] Adjustable layered dosing and mixing mechanism 4;

[0049] An adjustable layered dosing and mixing mechanism 4 is provided, and the adjustable layered dosing and mixing mechanism 4 is used for fully mixing sewage and medicine;

[0050] The bottom of the circulating sewage well 1 is fixedly connected to the middle of the water injection decomposition well 11 through a sewage pipe, a booster pump is installed in the dosing mixing box 12, a mixing bin is provided in the dosing mixing box 12, and the mixing bin of the dosing mixing box 12 is fixedly connected to the bottom of the water injection decomposition well 11 through a drug delivery pipe, and the water injection decomposition well 11 is provided in the middle of the circulating sewage well 1 group;

[0051] In this scheme, by setting a stratified sewage extraction mechanism 2 in the middle of the circulating sewage well 1, the sewage in the circulating sewage well 1 can be stratified by adjusting the annular driving plate 25 through the electric telescopic rod. After stratification, the sewage with a higher concentration at the bottom of the circulating sewage well 1 can flow into the water injection decomposition well 11 through the sewage discharge pipe at the bottom of the circulating sewage well 1 for mixing, so that pollutants with a relatively concentrated concentration can be extracted in a targeted manner, thereby improving the flow replenishment of heavy organic pollutants at the bottom of the circulating sewage well 1;

[0052] In this scheme, the gas generated by the decomposition of sewage and drugs can be uniformly collected by setting a constant pressure gas collection mechanism 3, which can not only decompose the damage to the environment by the gas, but also avoid excessive gas generation in the water injection decomposition well 11, so that a stable pressure environment can be formed in the water injection decomposition well 11. After the groundwater is injected with drugs, the gas environment is derived, and the increase of the gas pressure environment in the water injection decomposition well 11 can be reduced. At the same time, the bubbles in the sewage are reduced to reduce the contact decomposition with the drugs, thereby improving the contact reaction efficiency of the drugs and further improving the reaction effect of activation and degradation;

[0053] This solution can fully mix the sewage injected into the water injection and decomposition well 11 through the adjustable layered dosing mixing mechanism 4. The adjustable layered dosing mixing mechanism 4 can stir and dose while constantly changing the height in the water injection and decomposition well 11, which can not only increase the reaction effect between the drug and the sewage, but also reduce the problem of sedimentation and accumulation of heavy pollutants in the sewage.

[0054] Specifically, Figure 4As shown, the water blocking stratification plate 21 is circumferentially arranged on the inner wall of the circulating sewage well 1, one end of the water blocking stratification plate 21 is rotatably connected to a support ring 29, the bottom of the support ring 29 is fixedly connected to the inner wall of the circulating sewage well 1 through a support rod, the outer surface of the middle part of the other end of the water blocking stratification plate 21 is rotatably connected to the inner wall of the circulating sewage well 1, and the middle part of one end of the water blocking stratification plate 21 away from the support ring 29 is fixedly connected to a crank 22;

[0055] In this solution, the stratification of sewage in the circulating sewage well 1 is achieved by controlling the rotation of the water-blocking stratification plate 21, so that the heavy pollutants settled at the bottom of the circulating sewage well 1 and the light pollutants in the upper water layer can be separated, so that pollutants with more concentrated concentrations can be extracted in a targeted manner.

[0056] Furthermore, the outer surface of the circulating sewage well 1 is evenly provided with arc-surface push plates 23 and arc-surface connecting plates 24, both ends of the arc-surface push plates 23 are rotatably connected to the middle of the crank 22, and both ends of the arc-surface connecting plates 24 are rotatably connected to the end of the crank 22 away from the water-blocking stratification plate 21, and both ends of the arc-surface connecting plates 24 are fixedly connected to the side away from the circulating sewage well 1 with extrusion columns 28;

[0057] Through the connection between the crank 22, the arcuate push plate 23 and the arcuate connecting plate 24, when the crank 22 is rotated counterclockwise, the water-blocking stratification plate 21 arranged circumferentially in the circulating sewage well 1 can be driven to rotate synchronously through the connection between the arcuate push plate 23 and the arcuate connecting plate 24, thereby realizing the stratification of sewage in the circulating sewage well 1.

[0058] Furthermore, a protective isolation plate 26 is fixedly connected to the middle of the outer surface of the circulating sewage well 1, and a ring-shaped driving plate 25 is slidably connected to the protective isolation plate 26 near the inner side of the circulating sewage well 1. An extrusion groove 27 is opened on the outer surface of the annular driving plate 25, and the outer surface of the extrusion column 28 is slidably connected to the extrusion groove 27;

[0059] By pulling the protective isolation plate 26 with the telescopic rod to slide up and down along the inner wall of the protective isolation plate 26, the extrusion column 28 can be driven to move. By pulling the annular driving plate 25, the closure of the water-blocking stratification plate 21 can be directly adjusted. Compared with the traditional closed stratification, this scheme not only reduces the disturbance of the sewage during the stratification process, but also can achieve the effect of rapid stratification of the sewage.

[0060] Specifically, Figure 6As shown, the upper end of the water injection decomposition well 11 is fixedly connected to an exhaust bin 38, and a motor is installed on the upper surface of the exhaust bin 38. The motor driving shaft passes through the middle of the exhaust bin 38 and is fixedly connected to the transmission shaft 31. The outer surface of the transmission shaft 31 is rotatably connected to the water injection decomposition well 11. The transmission shaft 31 is fixedly connected to a fixed disk 32 at one end away from the exhaust bin 38, and the fixed disk 32 is fixedly connected to a connecting shaft 33 at one side away from the transmission shaft 31; the fixed disk 32 is symmetrically fixedly connected to both ends of the connecting shaft 33, and the connecting shaft 33 is provided with a reciprocating groove 34, and a cambered slider 35 is slidably connected in the reciprocating groove 34. The cambered slider 35 is rotatably connected to a connecting ring at one end away from the reciprocating groove 34, and a guide rod is fixedly connected to the circumference of the fixed disk 32, and the connecting ring is slidably connected to the guide rod, and a concave piston disk 36 is rotatably connected to one side of the connecting ring away from the connecting shaft 33, and the outer ring of the concave piston disk 36 is slidably connected to the inner wall of the water injection decomposition well 11;

[0061] In this solution, by opening a connecting shaft 33 on the connecting shaft 33, the arc surface slider 35 can slide in the reciprocating groove 34, driving the driving concave piston disk 36 of the connecting ring to reciprocate up and down on the inner wall of the water injection and decomposition well 11.

[0062] A one-way exhaust valve is installed on the circumference of the convex surface of the concave piston disc 36, and a gas collecting bin 37 is slidably connected to the outer side of the convex surface of the concave piston disc 36. The outer surface of the gas collecting bin 37 is fixedly connected to the inner wall of the water injection and decomposition well 11. An exhaust hole is opened on the circumference of the upper end of the water injection and decomposition well 11, and the exhaust hole penetrates the gas collecting bin 37 and communicates with the exhaust bin 38;

[0063] Among them, through the setting of the concave piston disk 36 and the gas collecting bin 37, the protrusion of the concave piston disk 36 slides on the inner wall of the gas collecting bin 37 to realize a piston-like movement. At the same time, through the setting of the one-way valve installed on the concave piston disk 36, not only can the gas generated when the sewage and drugs in the water injection decomposition well 11 are decomposed, but also the reaction decomposition efficiency between the drugs and sewage can be increased, and the inner wall of the water injection decomposition well 11 can be protected to prevent the deformation and damage of the inner wall of the water injection decomposition well 11 caused by excessive gas in the water injection decomposition well 11.

[0064] Specifically, Figure 7 As shown, the outer surface of the limiting ring 41 is rotatably connected with the first connecting plate 42 and the second connecting plate 43, the two ends of the first connecting plate 42 are rotatably connected to the second connecting plate 43, the two ends of the fulcrum of the first connecting plate 42 and the second connecting plate 43 away from the transmission shaft 31 are fixedly connected with porous stirring blades 45, the first connecting plate 42, the second connecting plate 43 and the porous stirring blade 45 are evenly arranged with high-pressure drug delivery tubes 44, the porous stirring blade 45 is evenly installed with high-pressure nozzles 46, the high-pressure nozzles 46 and the high-pressure drug delivery tubes 44 are connected to each other, and the limiting ring 41 is fixedly connected to the bottom of the concave piston disk 36 on the side close to the fixed disk 32;

[0065] Among them, the limit ring 41 is linearly and equidistantly slidably connected to the transmission shaft 31, and the concave piston disk 36 slides back and forth up and down on the inner wall of the water injection and decomposition well 11 to drive the limit ring 41 to continuously change its movement spacing. By arranging porous stirring blades 45 on the first connecting plate 42 and the second connecting plate 43, the limit ring 41 is driven to rotate by the transmission shaft 31. At the same time, the porous stirring blades 45 can not only stir the sewage, but also evenly install high-pressure nozzles 46 on the porous stirring blades 45, so that the drugs can be decomposed in different sewage layers. In addition, the filter holes in the porous stirring blades 45 can accelerate the mixing of drugs and sewage, thereby improving the sewage decomposition efficiency.

[0066] Moreover, through the design of this scheme, it is possible to ensure that the repair agent is added throughout the aquifer, avoiding the release of pollutants in the lighter contaminated layer of the upper aquifer or in the water-containing medium, making it impossible to completely oxidize and degrade the groundwater pollution, resulting in a rebound in the repair effect. At the same time, the agent can be added to the bottom of the aquifer where the pollutants are concentrated, with emphasis on the release of pollutants.

[0067] Furthermore, filter holes are evenly arranged in the porous stirring blade 45, and the filter holes in the porous stirring blade 45 are gradually densely arranged as they approach the bottom of the water injection decomposition well 11. The installation density of the high-pressure nozzle 46 gradually increases as the porous stirring blade 45 assembly approaches the bottom of the water injection decomposition well 11. A scraper 47 is fixedly connected to the outer surface of the bottom end of the transmission shaft 31. The bottom end of the transmission shaft 31 is fixedly connected to a universal flow guide pipe, and the universal flow guide pipe is fixedly connected to the drug delivery pipe of the dosing mixing box 12 away from the bottom end of the transmission shaft 31.

[0068] Through the design of this solution, the pollutants attached to the inner wall of the water injection and decomposition well 11 at the bottom of the water injection and decomposition well 11 can be scraped off, preventing the pollutants from attaching to the water injection and decomposition well 11 and causing incomplete oxidation and degradation of sewage.

[0069] The specific implementation method of the above embodiment is as follows:

[0070] First, the sewage generated in the industry will flow into the circulating sewage well 1 along with the pipeline assembly for unified sedimentation treatment. When the sewage is precipitated in the circulating sewage well 1, the operator starts the controller, and the controller controls the electric telescopic rod to start. Since the electric telescopic rod is installed on the outer surface of the circulating sewage well 1, and the telescopic shaft of the electric telescopic rod is fixedly connected to the upper surface of the annular driving plate 25;

[0071] At this time, the downward movement of the telescopic rod will drive the annular driving plate 25 to slide downward along the inner wall of the protective isolation plate 26 synchronously. At this time, since the extrusion grooves 27 uniformly provided in the annular driving plate 25 are slidably connected with the extrusion columns 28, and the extrusion columns 28 are fixedly connected to the two ends of the arc connecting plate 24, the downward movement of the annular driving plate 25 will drive the extrusion columns 28 to drive the crank 22 to start rotating in a clockwise direction. At this time, since the crank 22 is fixedly connected to one end of the protective isolation plate 26, the clockwise direction of the crank 22 will drive the water-blocking stratification plate 21 to start rotating synchronously. At this time, since the two ends of the arc push plate 23 are rotationally connected to the middle part of the crank 22, the arc push plate 23 can be linked to drive the water-blocking stratification plate 21 rotating in a circular manner on the inner wall of the circulating sewage well 1 to rotate synchronously in a clockwise direction. When the annular driving plate 25 slides downward to the protective isolation plate 26, at this time, the water-blocking stratification plate 21 stops rotating through the control of the controller in the telescopic rod, and the water-blocking stratification plate 21 begins to close in the circulating sewage well 1, which can reduce the disturbance to the water flow and the disturbance to the sediment, and at the same time, the sewage can be quickly stratified. At this time, since the sewage pipe is arranged at the bottom of the circulating sewage well 1, when the water-blocking stratification plate 21 is closed under the control of the electric telescopic rod, since the electric telescopic rod is electrically connected to the electric control valve installed in the sewage pipe at the bottom of the circulating sewage well 1, the electric control valve begins to open under the electrical feedback of the electric telescopic rod, and the heavy pollutants deposited at the bottom of the circulating sewage well 1 will flow into the water injection decomposition well 11 along with the sewage pipe assembly; thereby, the pollutants with a relatively concentrated concentration can be extracted in a targeted manner, the efficiency of drug decomposition and oxidation is improved, and the waste of drugs is reduced.

[0072] Furthermore, when sewage with a high concentration flows into the water injection and decomposition well 11 through the sewage pipe, the operator will deliver the previously developed drugs to the high-pressure drug delivery pipe 44 through the booster pump in the drug adding and mixing box 12. At this time, the drugs are gradually delivered to the high-pressure nozzle 46 for spraying through the high-pressure drug delivery pipe 44. Since the limit ring 41 is evenly and linearly arranged on the transmission shaft 31, and the porous stirring blade 45 is evenly provided with filter holes, the filter holes in the porous stirring blade 45 are gradually denser as they approach the bottom of the water injection and decomposition well 11. The installation density of the high-pressure nozzle 46 gradually increases as the porous stirring blade 45 assembly approaches the bottom of the water injection and decomposition well 11. The design of the scheme can meet the requirement of adding repair agents in the entire aquifer, avoid the release of lighter pollutants in the upper contaminated layer of the aquifer or in the water-containing medium, and fail to completely oxidize and degrade the groundwater pollution, resulting in a rebound in the repair effect. At the same time, the agent can be added to the bottom of the aquifer where the pollutants are concentrated.

[0073] Furthermore, when the drug reacts with the sewage, in order to prevent the sewage from being incompletely oxidized, the motor installed above the water injection decomposition well 11 is started. Since the motor drive shaft is fixedly connected to the transmission shaft 31, the rotation of the transmission shaft 31 will drive the connecting shaft 33 to start rotating synchronously, such as Figure 6 As shown, at this time, the mutual squeezing action of the reciprocating slide groove 34 and the arc-surface slider 35 provided in the connecting shaft 33 will drive the concave piston disc 36 to start to slide back and forth in the inner wall of the water injection decomposition well 11. Since the oxidation reaction between sewage and drugs in the water injection decomposition well 11 will produce a certain amount of gas, in order to prevent incomplete oxidation decomposition caused by excessive gas, at this time, the one-way exhaust valve installed on the concave piston disc 36 can discharge the gas generated in the water injection decomposition well 11 while the concave piston disc 36 reciprocates, which can not only timely clean the water injection decomposition well 11, but also effectively prevent the water injection decomposition well 11 from being completely decomposed. The gases generated when the sewage and drugs are decomposed in 11 are collected at the same time, which can increase the reaction decomposition efficiency between the drugs and sewage, and can protect the inner wall of the water injection decomposition well 11 to prevent the deformation and damage of the inner wall of the water injection decomposition well 11 caused by excessive gas in the water injection decomposition well 11. At the same time, the transmission shaft 31 is rotated to drive the limit ring 41 to rotate synchronously. The limit ring 41 starts to drive the porous stirring blades 45 to stir in different water layers. At the same time, the drugs can be sprayed from top to bottom on different water layers, so that the drugs and sewage layers can be fully oxidized and decomposed.

[0074] In summary, the present scheme can not only realize rapid stratification of sewage and targeted uniform oxidation and decomposition of high-concentration organic pollutants, but also prevent the release of pollutants in the upper contaminated layer of the aquifer or the water-containing medium by adding remediation agents throughout the aquifer, thereby preventing the groundwater pollution from being completely oxidized and degraded, resulting in a rebound in the remediation effect.
