Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of organic sewage decomposition, in particular to a groundwater organic pollution treatment device. BACKGROUND

[0002] Chlorinated hydrocarbons as organic pollution in groundwater environment, pollution is more serious in chemical enterprise area, chlorinated hydrocarbons as heavy organic pollution, because chlorinated hydrocarbons belong to heavy pollutants, groundwater pollution environment, pollutants are usually deposited at the bottom of aquifer.

[0003] Because these pollutants are usually deposited at the bottom of aquifer, so in the process of pumping treatment, must consider that the vertical hydraulic recharge is often greater than the horizontal hydraulic recharge, which directly affects the effect of pumping treatment. More troublesome is that when trying to enhance the treatment effect by a large amount of injection, often encounter the problem of large amount of injection, resulting in agent return slurry overflow, further reducing the treatment efficiency, in order to solve this problem, thus taking the sewage pumping decomposition, and because of the pumping of sewage, heavy pollutants in sewage will deposit at the bottom of water layer, and the pumping of sewage, heavy pollutants in sewage are easy to redistribute due to disturbance in the pumping process, resulting in part of the sewage not deposited at the bottom is also pumped out, which not only increases the difficulty of subsequent treatment, but also increases the use of drugs when sewage and drugs react due to the uneven concentration of pollutants.

[0004] In addition, during the sewage treatment process, when the sewage and drugs react, gas will inevitably be produced, if these gases cannot be discharged or collected in time, they will exist in the form of bubbles in the groundwater, which not only reduces the effective contact area of the agent and the sewage, thus reducing the reaction efficiency, but also affects the overall effect of activation degradation. More serious is that if the gas produced by decomposition is directly discharged into the air without treatment, it will undoubtedly cause additional pressure on the environment.

[0053] In the scheme, the adjustable layered medicine adding and mixing mechanism 4 can fully mix the sewage injected into the water injection and decomposition well 11, the medicine is added and stirred in the water injection and decomposition well 11 by continuously changing the height of the adjustable layered medicine adding and mixing mechanism 4, the reaction effect of the medicine and the sewage can be improved, and the problem of sedimentation and accumulation of heavy pollutants in the sewage is reduced.

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

[0055] In the present scheme, the rotation of the water-blocking layered plate 21 is controlled to realize the stratification of the sewage in the circulating sewage well 1, 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, and the pollutants with relatively concentrated concentration can be extracted.

[0056] Further, the outer surface of the circulating sewage well 1 is circumferentially uniformly provided with an arc surface push plate 23 and an arc surface connecting plate 24, both ends of the arc surface push plate 23 are rotatably connected to the middle part of the crank 22, both ends of the arc surface connecting plate 24 are rotatably connected to the end of the crank 22 away from the water-blocking layered plate 21, and the two ends of the arc surface connecting plate 24 away from the circulating sewage well 1 are fixedly connected with an extrusion column 28;

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

[0058] Further, the outer surface of the circulating sewage well 1 is fixedly connected with a protective isolation plate 26 in the middle part, the protective isolation plate 26 is slidably connected with a ring-shaped driving plate 25 close to the inner side of the circulating sewage well 1, the outer surface of the ring-shaped driving plate 25 is circumferentially provided with an extrusion groove 27, and the outer surface of the extrusion column 28 is slidably connected in the extrusion groove 27;

[0059] By pulling the protective isolation plate 26 to slide up and down along the inner wall of the protective isolation plate 26, the extrusion column 28 can be driven to move, and by pulling the ring-shaped driving plate 25, the closing of the water-blocking layered plate 21 can be directly adjusted. Compared with the traditional closed stratification, the present scheme not only reduces the disturbance to the sewage during stratification, but also can realize the effect of rapid stratification of the sewage.

[0060] Specifically, as shown in the drawings, Figure 6As shown, an exhaust chamber 38 is fixedly connected to the upper end of the water injection decomposition well 11. A motor is installed on the upper surface of the exhaust chamber 38. The motor drive shaft passes through the middle of the exhaust chamber 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. A fixed plate 32 is fixedly connected to the end of the transmission shaft 31 away from the exhaust chamber 38. A connecting shaft 33 is fixedly connected to the side of the fixed plate 32 away from the transmission shaft 31. The fixed plate 32 is symmetrically fixedly connected to both ends of the connecting shaft 33. The connecting shaft 33 has a reciprocating slide groove 34. An arc-shaped slider 35 is slidably connected in the reciprocating slide groove 34. A connecting ring is rotatably connected to the end of the arc-shaped slider 35 away from the reciprocating slide groove 34. A guide rod is fixedly connected to the circumference of the fixed plate 32. The connecting ring is slidably connected to the guide rod. A concave piston plate 36 is rotatably connected to the side of the connecting ring away from the connecting shaft 33. The outer ring of the concave piston plate 36 is slidably connected to the inner wall of the water injection decomposition well 11.

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

[0062] A one-way exhaust valve is installed on the circumference of the protruding surface of the concave piston disc 36. A gas collection chamber 37 is slidably connected to the outer side of the protruding surface of the concave piston disc 36. The outer surface of the gas collection chamber 37 is fixedly connected to the inner wall of the water injection decomposition well 11. An exhaust hole is opened on the upper circumference of the water injection decomposition well 11. The exhaust hole passes through the gas collection chamber 37 and communicates with the exhaust chamber 38.

[0063] The concave piston disc 36 and the gas collection chamber 37 are designed to achieve piston-like motion by sliding the concave piston disc 36 against the inner wall of the gas collection chamber 37. The one-way valve installed on the concave piston disc 36 can not only collect the wastewater and the gas generated during the decomposition of drugs in the water injection decomposition well 11 in a timely manner, increasing the reaction decomposition efficiency between drugs and wastewater, but also protect the inner wall of the water injection decomposition well 11 from deformation and damage caused by excessive gas in the water injection decomposition well 11.

[0064] Specifically, such as Figure 7 As shown, the outer surface of the limiting ring 41 is circumferentially connected to a first connecting plate 42 and a 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 first connecting plate 42 and the second connecting plate 43 are fixedly connected to the fulcrum on the side away from the drive shaft 31. High-pressure drug delivery pipes 44 are evenly arranged on the first connecting plate 42, the second connecting plate 43 and the porous stirring blades 45. High-pressure nozzles 46 are evenly installed in the porous stirring blades 45. The high-pressure nozzles 46 are connected to the high-pressure drug delivery pipes 44. The side of the limiting ring 41 near the fixed plate 32 is fixedly connected to the bottom of the concave piston plate 36.

[0065] The limiting ring 41 is linearly and equidistantly connected to the transmission shaft 31, and the concave piston disc 36 reciprocates on the inner wall of the water injection decomposition well 11 to drive the limiting ring 41 to change the movement interval between the limiting rings 41. The first connecting plate 42 and the second connecting plate 43 are provided with the porous stirring blade 45, which is driven to rotate by the transmission shaft 31. At the same time, the porous stirring blade 45 can not only stir the sewage, but also can make the medicine decompose in different sewage layers through the high-pressure nozzles 46 uniformly installed on the porous stirring blade 45. In addition, the mixing of the medicine and the sewage can be accelerated through the filter holes in the porous stirring blade 45, so as to improve the sewage decomposition efficiency.

[0066] In addition, the design can meet the requirement of adding repair medicine in the entire aquifer, avoid the pollution of the upper layer of the aquifer, and avoid the release of pollutants in the aquifer medium, so as to cause the rebound of the repair effect, and at the same time, the medicine can be added to the bottom of the aquifer where the pollutants are concentrated.

[0067] Further, the filter holes are uniformly arranged in the porous stirring blade 45, and the filter holes in the porous stirring blade 45 are gradually dense when approaching the bottom of the water injection decomposition well 11. The installation density of the high-pressure nozzles 46 gradually increases when the porous stirring blade 45 assembly approaches the bottom of the water injection decomposition well 11. The scraper 47 is fixedly connected to the outer surface of the bottom end of the transmission shaft 31. The universal flow guide pipe is fixedly connected to the medicine conveying pipe of the medicine mixing box 12 away from the bottom end of the transmission shaft 31.

[0068] Through the design, the pollutants attached to the inner wall of the water injection decomposition well 11 at the bottom of the water injection decomposition well 11 can be scraped, so as to prevent the pollutants from being attached to the water injection decomposition well 11 and causing incomplete oxidation and degradation of the 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 through the pipeline assembly for unified sedimentation treatment. When the sedimentation of the sewage in the circulating sewage well 1 is completed, the operator starts the controller to control 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 cause the annular drive plate 25 to slide down synchronously along the inner wall of the protective isolation plate 26. Since the extrusion grooves 27 evenly distributed in the annular drive plate 25 are slidably connected to the extrusion columns 28, and the extrusion columns 28 are fixedly connected to both ends of the arc-shaped connecting plate 24, the downward movement of the annular drive plate 25 will cause the extrusion columns 28 to drive the crank 22 to start rotating clockwise. Since the crank 22 is fixedly connected to one end of the protective isolation plate 26, the clockwise rotation of the crank 22 will cause the water-blocking layer plate 21 to start rotating synchronously. Since the two ends of the arc-shaped push plate 23 are rotatably connected to the middle of the crank 22, the arc-shaped push plate 23 can drive the water-blocking layer plate 21, which rotates circumferentially on the inner wall of the circulating sewage well 1, to rotate clockwise synchronously. When the annular drive plate 25 slides down to the protective isolation plate... At the bottom of the 26th stage, the controller in the telescopic rod stops the water-blocking stratification plate 21 from rotating. The water-blocking stratification plate 21 then begins to close within the circulating sewage well 1. This reduces disturbance to the water flow and sediment, while also enabling rapid stratification of the sewage. Since the sewage pipe is located at the bottom of the circulating sewage well 1, when the water-blocking stratification plate 21 closes under the control of the electric telescopic rod, the electric control valve installed in the sewage pipe at the bottom of the circulating sewage well 1, which is electrically connected to the electric telescopic rod, opens under the electrical feedback of the electric telescopic rod. Heavy pollutants deposited at the bottom of the circulating sewage well 1 then flow into the water injection decomposition well 11 through the sewage pipe assembly. This allows for the targeted extraction of a more concentrated concentration of pollutants, improving the efficiency of drug decomposition and oxidation while reducing drug waste.

[0072] Furthermore, when high-concentration wastewater flows into the water injection decomposition well 11 through the sewage pipe, the operator delivers the previously developed drug to the high-pressure delivery pipe 44 via the booster pump in the dosing and mixing tank 12. The drug is then gradually delivered to the high-pressure nozzle 46 for spraying. Since the limiting ring 41 is uniformly and linearly set on the drive shaft 31, and the porous stirring blade 45 is uniformly provided with filter holes, the filter holes in the porous stirring blade 45 gradually become denser 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. Through the design of the scheme, the remediation agent can be added to the entire aquifer, avoiding the release of pollutants from the lighter pollutants in the upper polluted layer of the aquifer or the aquifer medium, which would prevent the groundwater pollution from being completely oxidized and degraded, causing a rebound in the remediation effect. At the same time, the agent can be specifically added to the bottom plate of the aquifer where the pollutants are concentrated.

[0073] Further, when the medicine reacts with the sewage, to prevent incomplete oxidation of the sewage, the motor above the water injection decomposition well 11 is started, since the motor drive shaft is fixedly connected with the transmission shaft 31, the transmission shaft 31 rotates to drive the connecting shaft 33 to start synchronous rotation, as shown in Figure 6 the reciprocal sliding groove 34 in the connecting shaft 33 and the arc surface sliding block 35 are extruded to drive the concave piston disc 36 to reciprocate in the inner wall of the water injection decomposition well 11, since the sewage and the medicine in the water injection decomposition well 11 will produce a certain gas by oxidation reaction, to prevent incomplete oxidation decomposition caused by too much gas, the one-way exhaust valve arranged on the concave piston disc 36 can exhaust the gas produced in the water injection decomposition well 11 while the concave piston disc 36 reciprocates, which can not only collect the gas produced by the sewage and the medicine in the water injection decomposition well 11 at the same time, but also increase the reaction and decomposition efficiency between the medicine and the sewage, and protect the inner wall of the water injection decomposition well 11, prevent the deformation and damage of the inner wall of the water injection decomposition well 11 caused by too much gas in the water injection decomposition well 11, and drive the limiting ring 41 to rotate synchronously by the transmission shaft 31, and drive the porous stirring blade 45 to stir in different water layers, which can also spray medicine from top to bottom in different water layers, so as to fully oxidize and decompose the medicine and the sewage layer.

[0074] In summary, the present scheme can realize rapid layering of sewage, targeted oxidation and decomposition of organic high-concentration pollutants, and the addition of repair reagents in the entire water layer can avoid the release of pollutants in the upper layer of the water layer or the water medium, which cannot completely oxidize and degrade the groundwater pollution, causing the rebound of the repair effect, and at the same time, the reagent can be added to the water layer bottom plate where the pollutants are concentrated, thereby improving the oxidation and decomposition efficiency of the sewage.

[0075] The above working process is described in detail in the description Figures 1 to 7 .
