Description

Technical Field

[0001] The present invention relates to the technical field of mine water purification treatment, and particularly relates to a treatment device and method for mine water inflow. Background Art

[0002] In China, some mines in the coal production capacity have reached the end of their life cycles, and some coal mines with backward production capacity do not meet the requirements of work safety, or have too high mining costs and serious losses, and will be closed or abandoned. During the mining process, on the one hand, the aquifer, aquitard and water-conducting fault are exposed and damaged, and on the other hand, the surrounding rock strata move and the ground surface subsides, resulting in the phenomenon of groundwater or surface water flowing into the shaft or roadway, which is called mine water inflow.

[0003] At present, in order to alleviate the problem of water supply and demand, it is an inevitable trend to recycle and treat mine sewage and reduce environmental pollution. Due to the scouring of the coal seam and the influence of domestic sewage in the mining process, the suspended solids content in the mine water inflow is high, and it contains a high content of emulsified oil, dissolved oil substances, and also contains iron, manganese, magnesium, calcium, sulfate and various heavy metal ions (such as chromium, lead, copper, zinc, nickel, arsenic, lead, ammonia nitrogen ions), etc.

[0004] In the current common treatment of mine water inflow pollution, mostly lime neutralization precipitation method, simple sludge reflux method, HDS treatment method, redox method, ion exchange method, etc. are used. These processes have their own characteristics, but also have their own drawbacks. Generally, the mine water inflow contains a high content of emulsified oil and dissolved oil substances. Commonly, membrane technologies such as nano-ceramic membranes are used for oil removal, but this will increase the burden on the membrane treatment system, and will also cause serious membrane pollution to the membrane system, affecting the flow efficiency. Moreover, the operation and maintenance cost of the membrane system is high, and the operation stability is poor. Subsequently, it will not only waste precious mine water resources, but also may cause a series of environmental pollution problems; and traditionally, various filter materials are often used to remove heavy metal ions in the mine water inflow. Although the filter material layer can be reused by backwashing, improving the service life of the filter material layer, if the filter material layer needs to be backwashed, then the filtration and purification treatment of the mine water inflow will have to be suspended, and the filtration and purification treatment can only be started again after the backwashing of the filter material layer is completed, reducing the work efficiency and purification efficiency, and unable to achieve continuous filtration and purification treatment of the mine water inflow.

[0019] According to the above treatment method of the treatment device for mine water inrush, the following steps are included:

[0020] S1: Input the mine water inflow into the grid tank through the water inlet pipe to remove large particulate suspended matter in the water inflow; the preliminarily purified mine water inflow enters the flocculation reaction tank through the pipe, and a flocculant is added for flocculation reaction to form small floccules of suspended matter in the water inflow; the mine water inflow enters the coagulant aid reaction tank from the lower part of the flocculation reaction tank, and a coagulant aid is added for coagulant aid reaction to convert the small floccules into larger floccules; the mine water inflow enters the inclined tube sedimentation tank from the upper part of the coagulant aid reaction tank, and the floccules are separated from the water body through the inclined tube network of the inclined tube sedimentation tank;

[0021] S2: The supernatant of the inclined tube sedimentation tank enters the first adjustment sedimentation tank through the pipe. The pH value of the water is adjusted to 10.3 - 10.8 by adding an alkali agent, and magnesium ions in the water are removed; the adjusted mine water inflow in the first adjustment sedimentation tank enters the oil removal sedimentation tank through the pipe. A demulsifier is added, and air flotation is carried out through aeration to remove oil, and iron and manganese ions in the water are removed; the water after oil removal in the oil removal sedimentation tank overflows into the second adjustment sedimentation tank. The pH value of the water is adjusted to 7.3 - 7.8 by adding an acid agent, and calcium ions in the water are removed; the sludge in the grid tank, flocculation reaction tank, coagulant aid reaction tank, and inclined tube sedimentation tank, as well as the sludge and ion precipitates in the first adjustment sedimentation tank, oil removal sedimentation tank, and second adjustment sedimentation tank, are discharged into the sludge thickening tank. The thickened sludge in the sludge thickening tank is dehydrated by a spiral sludge dewatering machine to achieve solid-liquid separation. The supernatant generated in the sludge thickening tank and the spiral sludge dewatering machine is returned to the grid tank, and the separated sludge is transported out for treatment;

[0022] S3: The adjusted mine water inflow in the second adjustment sedimentation tank flows into the multi-media filter tank through the upper through-hole, and the suspended matter is further removed through the multi-media filter layer, and iron, manganese, magnesium, calcium, sulfate, and various heavy metal ions in the water are effectively removed; the purified mine water inflow in the multi-media filter tank enters the disinfection tank through the pipe, and the water is disinfected and sterilized by adding a disinfectant; the water after disinfection and sterilization in the disinfection tank enters the clear water tank through the pipe, and the water in the clear water tank can be used for daily domestic water, road sprinkling, agricultural irrigation, backwashing, etc.;

[0023] S4: When backwashing is required for the multi-media filtration layer in the multi-media filter, the cylinder descends, driving the mounting plate, the first connecting plate, the support plate, the linkage mechanism, the second connecting plate, the partition plate, and the clamping mechanism to descend as a whole. The linkage mechanism drives the clamping plates of the clamping mechanism to approach each other, clamping the multi-media filtration layer that needs to be backwashed. Then, the cylinder ascends, synchronously driving the multi-media filtration layer to rise. When the multi-media filtration layer leaves the multi-media filter, it is moved to directly above the flushing pool by the transfer mechanism. The cylinder descends to place the multi-media filtration layer that needs to be backwashed into the flushing pool. Water in the clear water tank is transported into the flushing pool for backwashing. At this time, there is still a set of multi-media filtration layers in the multi-media filter that can be used to continue filtering and purifying the mine water inflow. After the backwashing of the multi-media filtration layer in the flushing pool is completed, the backwashed multi-media filtration layer is placed back into the multi-media filter through the above-mentioned clamping and transfer steps. The linkage mechanism drives the clamping plates of the clamping mechanism to move away from each other. The mutually separated clamping plates can clamp another set of multi-media filtration layers and transfer the other set of multi-media filtration layers to the flushing pool for backwashing, ensuring continuous filtering and purification of the mine water inflow.

[0024] Compared with the prior art, the present invention provides a treatment device and method for mine water inflow, having the following beneficial effects:

[0025] 1. The present invention adopts a process treatment method of "grille filtration + flocculation - coagulation precipitation + inclined tube precipitation + primary pH adjustment precipitation + oil removal precipitation + secondary pH adjustment precipitation + multi-media filtration + disinfection and sterilization", with a simple process, being economically effective, having good treatment effects, low costs, and good effluent water quality, and is suitable for popularization and use;

[0026] 2. The present invention uses the method of air flotation for oil removal to remove emulsified oil and dissolved oil substances in the mine water inflow. Without using membrane technology, it reduces the operation and maintenance costs. Through aeration, not only can the oil and water be stratified, but also the iron and manganese ions in the water inflow can be oxidized to generate suspended Fe(OH)3 particles and MnO2 precipitates, facilitating the removal of iron and manganese ions and ensuring the effluent water quality;

[0027] 3. By the coordinated use of the transfer mechanism, cylinder, linkage mechanism, and clamping mechanism, the present invention can clamp a set of multi-media filter layers, transfer them from the multi-media filter tank to the flushing tank for backwashing, facilitating subsequent reuse and reducing maintenance costs. After the backwashing is completed, the multi-media filter layers are clamped and transferred back to the multi-media filter tank. The clamping plates are loosened from this set of multi-media filter layers, and the mutually separated clamping plates can clamp another set of multi-media filter layers, transfer the other set of multi-media filter layers to the flushing tank for backwashing, ensuring that there is at least one set of multi-media filter layers in the multi-media filter tank, guaranteeing continuous filtration and purification treatment of the mine water inflow, and improving work efficiency and purification efficiency.

Each group of limiting strips is located on both sides inside the grid tank 1 and is arranged oppositely, that is, two limiting strips are provided on one side, and a limiting groove for limiting and guiding the grid mesh 102 is provided between every two limiting strips, so as to prevent the grid mesh 102 from being installed improperly.

[0064] Refer to Figure 4 and Figure 6 In this embodiment, a demulsifier dosing tank 601 is provided at the top of the oil removal and sedimentation tank 6. The emulsion dosing pipe 602 of the demulsifier dosing tank 601 extends into the oil removal and sedimentation tank 6.

An overflow weir plate 604 is provided at the upper part inside the oil removal and sedimentation tank 6 to adjust the overflow speed of the mine inflowing water. An oil-water probe 605 is provided at the connection between the oil removal and sedimentation tank 6 and the second regulating sedimentation tank 7. A oil pump 606 is provided at the top of the oil removal and sedimentation tank 6.

[0065] Specifically, an exhaust port is connected to the cover plate 14 of the oil removal sedimentation tank 6; the aeration pipe 603 is connected to an external blower, and a number of micropores are provided on the aeration pipe 603. During operation, under the pressure of the gas, the micropores will automatically open, and the gas will enter the oil removal sedimentation tank 6 to contact the mine water inflow. If the pressure disappears, the micropores on the aeration pipe 603 will automatically close to prevent the mine water inflow from flowing back into the micropores. By using micropore aeration, the gas consumption is small, saving gas usage and improving the mixing effect of the water inflow and the demulsifier, thereby improving the efficiency of oil-water separation; the demulsifier has a better demulsification effect when the pH value is about 10; the oil-water probe 605 is located below the upper through hole of the oil removal sedimentation tank 6; the gas enters the aeration pipe 603 through the blower, and the gas sprays out from the micropores to aerate and demulsify the mine water inflow, and perform air flotation oil removal. The oil in the water inflow is brought to the upper layer of the water inflow with the gas after demulsification. The oil in the upper layer first flows out through the overflow weir plate 604. The oil-water probe 605 first detects the overflowing oil, and then transmits a signal to the oil pump 606 through the controller. The oil pump 606 starts to suck the oil, which is convenient for centralized treatment after the oil is collected. When the oil-water probe 605 detects water, the oil pump 606 stops pumping; and through aeration, the iron and manganese ions in the water inflow are oxidized to generate suspended Fe(OH)3 particles and MnO2 precipitates, which is convenient for removing iron and manganese ions and ensuring the water quality of the effluent.

One hollow partition 901 is arranged between every 2 groups of limiting components, dividing the flushing tank 9 into 6 spaces. The lower parts of 5 spaces corresponding to the limiting components are all communicated with a drain pipe 19; through backwashing, suspended solids, flocs, precipitates, etc. on the five-layer medium filtration layer are flushed out by the backwashing water flow and discharged outside through the drain pipe 19; each space is separated by the hollow partition 901. During backwashing, the purposes of non-repeated pollution and clean cleaning are achieved, which is convenient for subsequent reuse, reduces the maintenance cost, improves the effect of subsequent repeated filtration of various heavy metal ions, and prolongs the service life of the medium filtration layer; preferably, the top of the medium filtration layer can be set as an openable cover body. When the medium filtration layer has been used for a long time and loses the function of removing relevant heavy metal ions, the cover body can be opened to replace the internal filter material, so that the medium filtration layer can continue to be used and the service life of this system is improved.

[0087] According to the above treatment method of the treatment device for mine water, the following steps are included:

[0088] S1: Input the mine water inflow into the grid tank 1 through the water inlet pipe 12 to remove large particulate suspended matter in the water inflow. The preliminarily purified mine water inflow enters the flocculation reaction tank 2 through a pipe, and a flocculation reaction is carried out by adding PAC, so that small particulate suspended matter in the water inflow forms minute flocs. The mine water inflow enters the coagulant aid reaction tank 3 from the lower part of the flocculation reaction tank 2, and a coagulant aid reaction is carried out by adding PAM, so that the minute flocs are transformed into larger flocs. The mine water inflow enters the inclined tube sedimentation tank 4 from the upper part of the coagulant aid reaction tank 3, and the flocs are separated from the water body through the inclined tube network 402 of the inclined tube sedimentation tank 4.

[0089] S2: The supernatant of the inclined tube sedimentation tank 4 enters the first adjustment sedimentation tank 5 through a pipe. The pH value of the water is adjusted to 10.3 - 10.8 by adding sodium hydroxide, and magnesium ions generate magnesium hydroxide, which precipitates out. The adjusted mine water inflow in the first adjustment sedimentation tank 5 enters the oil removal sedimentation tank 6 through a pipe. By adding a demulsifier, gas enters the aeration pipe 603 through a blower, and the gas sprays out from micropores to carry out aeration demulsification on the mine water inflow for air flotation oil removal. The oil in the water inflow is carried to the upper layer of the water inflow after demulsification by the gas. The oil in the upper layer first flows out through the overflow weir plate 604. The oil water probe 605 first detects the overflowed oil, and then transmits a signal to the oil pump 606 through a controller. The oil pump 606 starts to suck the oil for convenient centralized treatment after collection. When the oil water probe 605 detects water, the oil pump 606 stops pumping. And through aeration, iron and manganese ions in the water inflow are oxidized to generate suspended Fe(OH)3 particles and MnO2 precipitates, which is convenient for removing iron and manganese ions to ensure the water quality of the effluent. The water after oil removal in the oil removal sedimentation tank 6 overflows into the second adjustment sedimentation tank 7. The pH value of the water is adjusted to 7.3 - 7.8 by adding dilute sulfuric acid, and calcium sulfate precipitates are produced with calcium ions in the water inflow for convenient separation. The sludge in the grid tank 1, flocculation reaction tank 2, coagulant aid reaction tank 3 and inclined tube sedimentation tank 4 and the sludge and ion precipitates in the first adjustment sedimentation tank 5, oil removal sedimentation tank 6 and second adjustment sedimentation tank 7 are discharged into the sludge thickening tank. The concentrated sludge in the sludge thickening tank is dehydrated by a spiral sludge dewatering machine to achieve solid-liquid separation. The supernatant generated in the sludge thickening tank and the spiral sludge dewatering machine is refluxed to the grid tank 1, and the supernatant is recycled again so that the water inflow can meet the standards for use. The separated sludge is transported out for treatment and can be incinerated.

[0090] S3: The regulated mine water in the second regulating sedimentation tank 7 flows into the multi-media filter tank 8 through the upper through-holes, and further removes suspended solids through the first media filter layer 801, the second media filter layer 802, the third media filter layer 803, the fourth media filter layer 804 and the fifth media filter layer 805, and effectively removes iron, manganese, magnesium, calcium, sulfate and various heavy metal ions in the water; The purified mine water in the multi-media filter tank 8 enters the disinfection tank 10 through a pipeline, and the water is disinfected by adding sodium hypochlorite; The water after disinfection and sterilization in the disinfection tank 10 enters the clear water tank 11 through a pipeline, and the water in the clear water tank 11 can be used for daily domestic water, road sprinkling, agricultural irrigation, backwashing, etc.;

[0091] S4: When the multi-media filter layer in the multi-media filter pool 8 needs to be backwashed, the cylinder 22 is lowered, driving the mounting plate 23, the first connecting plate 24, the support plate 25, the linkage mechanism 26, the second connecting plate 27, the partition plate 28 and the clamping mechanism 29 to descend as a whole, and by starting the second motor 261, the second motor 261 drives the first rotating shaft 262 to rotate, the first rotating shaft 262 drives the first bevel gear 263 to rotate, the first bevel gear 263 drives the second bevel gears 264 on both sides to rotate, the second bevel gear 264 drives the second rotating shaft 265 and the third bevel gear 266 to rotate, and the third bevel gear 266 drives the fourth The bevel gear 267 rotates, the fourth bevel gear 267 drives the third rotating shaft 268 to rotate, the third rotating shaft 268 drives the active synchronous pulley 269 to rotate, the active synchronous pulley 269 drives the driven synchronous pulley 270 on the same side to rotate synchronously through the synchronous belt 271, the driven synchronous pulley 270 drives the fourth rotating shaft 272 to rotate, the fourth rotating shaft 272 drives the fifth bevel gear 273 to rotate, the fifth bevel gear 273 drives the sixth bevel gear 291 to rotate, the sixth bevel gear 291 drives the second threaded rod 292 to rotate, thereby driving the clamping plates 293 to approach each other, clamping a group of multi-media filter layers that need to be backwashed, and then The cylinder 22 rises and drives the multi-media filter layer to rise synchronously. When the multi-media filter layer leaves the multi-media filter pool 8, the first motor 217 is started and the first motor 217 drives the first threaded rod 214 to rotate, thereby driving the threaded block 215 to move along the slide 213, so that the movable plate 216 can move from the multi-media filter pool 8 to the flushing pool 9, so that the multi-media filter layer is located directly above the flushing pool 9. The cylinder 22 descends and places the multi-media filter layer that needs to be backwashed into the flushing pool 9. By transporting water from the clean water pool 11 to the flushing pool 9 for backwashing, at this time, there is still water in the multi-media filter pool 8. A group of multi-media filter layers can be used to continue filtering and purifying the mine water. After the backwashing of the multi-media filter layer in the flushing tank 9 is completed, the backwashed multi-media filter layer is placed back into the multi-media filter tank 8 through the above-mentioned clamping and transporting steps. The reversal of the second motor 261 drives the clamping plates 293 away from each other. The clamping plates 293 away from each other can clamp another group of multi-media filter layers. At this time, the other group of multi-media filter layers can be transported to the flushing tank 9 for backwashing, thereby ensuring continuous filtering and purification of the mine water, extending the service life of the medium filter layer, and improving the work efficiency and purification efficiency.

10. The treatment method of the treatment device for mine water inrush according to any one of claims 1-9, characterized in that, It includes the following steps: S1: Input the mine water inflow into the grille tank (1) through the water inlet pipe (12) to remove large particulate suspended matter in the water inflow. The preliminarily purified mine water inflow enters the flocculation reaction tank (2) and undergoes a flocculation reaction by adding a flocculant. Then the mine water inflow enters the coagulant aid reaction tank (3) and undergoes a coagulant aid reaction by adding a coagulant aid. Then the mine water inflow enters the inclined tube sedimentation tank (4), and the flocs are separated from the water body through the inclined tube network (402) of the inclined tube sedimentation tank (4). S2: The supernatant of the inclined tube sedimentation tank (4) enters the first adjustment sedimentation tank (5), and the pH value of the water is adjusted to 10.3 - 10.8 by adding an alkali agent, and magnesium ions in the water are removed. The mine water inflow passing through the first adjustment sedimentation tank (5) enters the oil removal sedimentation tank (6), and a demulsifier is added, and air flotation oil removal is carried out through aeration, and iron and manganese ions in the water are removed. The water passing through the oil removal sedimentation tank (6) enters the second adjustment sedimentation tank (7), and the pH value of the water is adjusted to 7.3 - 7.8 by adding an acid agent, and calcium ions in the water are removed. The sludge in the grille tank (1), flocculation reaction tank (2), coagulant aid reaction tank (3) and inclined tube sedimentation tank (4) and the sludge and ion precipitates in the first adjustment sedimentation tank (5), oil removal sedimentation tank (6) and second adjustment sedimentation tank (7) are discharged into the sludge thickening tank. S3: The mine water inflow in the second adjustment sedimentation tank (7) flows into the multi-media filtration tank (8), and the suspended matter is further removed through the multi-media filtration layer, and iron, manganese, magnesium, calcium, sulfate and various heavy metal ions in the water are effectively removed. The mine water inflow passing through the multi-media filtration tank (8) enters the disinfection tank (10), and the water is disinfected and sterilized by adding a disinfectant. The water passing through the disinfection tank (10) enters the clear water tank (11). S4: When the multi-media filter layer in the multi-media filter tank (8) needs to be backwashed, the cylinder (22) descends, driving the linkage mechanism (26) and the clamping mechanism (29) to descend as a whole. The clamping plates (293) of the clamping mechanism (29) are driven by the linkage mechanism (26) to approach each other, clamping a set of multi-media filter layers that need to be backwashed. Then, the cylinder (22) ascends, synchronously driving the multi-media filter layer to rise. When the multi-media filter layer leaves the multi-media filter tank (8), it is transported to directly above the flushing tank (9) by the transfer mechanism (21). The cylinder (22) descends to place the multi-media filter layer that needs to be backwashed into the flushing tank (9). Water in the clear water tank (11) is conveyed into the flushing tank (9) for backwashing. At this time, there is another set of multi-media filter layers in the multi-media filter tank (8) that can continue to be used for filtering and purifying the mine water inflow. After the backwashing of the multi-media filter layer in the flushing tank (9) is completed, the backwashed multi-media filter layer is placed back into the multi-media filter tank (8) through the above-mentioned clamping and transfer steps. The clamping plates (293) of the clamping mechanism (29) are driven by the linkage mechanism (26) to move away from each other. The mutually separated clamping plates (293) can clamp another set of multi-media filter layers and transport them to the flushing tank (9) for backwashing, ensuring continuous filtering and purification of the mine water inflow.
