Description

Technical Field

[0001] The invention relates to the technical field of mine water purifying treatment, and in particular to a treatment device and method for mine water purging. Background Art

[0002] During the mining process, on the one hand, aquifers, impermeable layers and water-conducting faults are exposed and destroyed, and on the other hand, surrounding rock strata are caused to move and the surface collapse, resulting in the phenomenon of groundwater or surface water gushing into the shaft or tunnel, which is called mine water inrush.

[0003] At present, in order to alleviate the problem of water supply and demand, it is an inevitable trend to recycle mine wastewater and reduce environmental pollution. Mine water gushes due to the scouring of coal seams and the influence of domestic sewage during the mining process. Therefore, the suspended matter content in the mine water is high, and it contains high emulsified oil and dissolved oil substances. It 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] At present, the common mine water pollution control process mostly adopts lime neutralization precipitation method, simple sludge return method, HDS treatment method, oxidation-reduction method, ion exchange method, etc. These processes have their own characteristics, but also have their own disadvantages. Mine water generally contains high emulsified oil and dissolved oil substances. Common membrane technologies such as nano-ceramic membranes are used for oil removal, but this will increase the burden of the membrane treatment system, and will also cause serious membrane pollution to the membrane system, affecting the flow efficiency. The operation and maintenance cost of the membrane system is high, and the operation stability is poor, which will not only waste precious 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 mine water. Although the filter layer can be used again by backwashing to increase the service life of the filter layer, if the filter layer needs to be backwashed, the filtration and purification of the mine water must be suspended. After the backwashing of the filter layer is completed, the filtration and purification can be started again, which reduces the work efficiency and purification efficiency, and cannot achieve continuous filtration and purification of mine water.

[0005] Therefore, the applicant proposes a device and method for treating mine water inrush to solve the above problems. Summary of the invention

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

[0020] S1: The mine water is input into the grid pool through the water inlet pipe to remove the large suspended particles in the water; the mine water after preliminary purification enters the flocculation reaction pool through the pipe, and the flocculation reaction is carried out by adding flocculants, so that the small suspended particles in the water form micro-flocs; the mine water enters the coagulant-assisted reaction pool through the lower part of the flocculation reaction pool, and the coagulant-assisted reaction is carried out by adding coagulants, so that the micro-flocs are converted into larger flocs; the mine water enters the inclined tube sedimentation tank through the upper part of the coagulant-assisted reaction pool, and the flocs are separated from the water body through the inclined pipe network of the inclined tube sedimentation tank;

[0021] S2: The supernatant of the inclined tube sedimentation tank enters the first regulating sedimentation tank through a pipeline, and the pH value of the water is adjusted to 10.3-10.8 by adding an alkali agent, and the magnesium ions in the water are removed; the regulated mine water in the first regulating sedimentation tank enters the oil removal sedimentation tank through a pipeline, and demulsifier is added, and aeration is used for flotation to remove oil, and iron and manganese ions in the water are removed; the deoiled water in the oil removal sedimentation tank enters the second regulating sedimentation tank through overflow, and the pH value of the water is adjusted to 7 by adding an acid agent .3~7.8, and remove calcium ions in the water; discharge the sludge in the grid tank, flocculation reaction tank, coagulant reaction tank and inclined tube sedimentation tank and the sludge and ion precipitates in the first regulating sedimentation tank, oil removal sedimentation tank and second regulating sedimentation tank into the sludge thickening tank, and dehydrate the concentrated sludge in the sludge thickening tank through a screw stack sludge dewatering machine to achieve solid-liquid separation, and return the supernatant produced in the sludge thickening tank and the screw stack sludge dewatering machine to the grid tank, and transport the separated sludge for treatment;

The method for treating water in a mine according to any one of claims 1 to 9, characterized in that: The steps include: S1: The mine water is fed into the grid pool (1) through the water inlet pipe (12) to remove large suspended solids in the water; the mine water after preliminary purification enters the flocculation reaction pool (2) to perform flocculation reaction by adding flocculants; the mine water then enters the coagulation aid reaction pool (3) to perform coagulation aid reaction by adding coagulants; the mine water then enters the inclined tube sedimentation tank (4) to separate the flocs 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 regulating sedimentation tank (5), and the pH value of the water is adjusted to 10.3-10.8 by adding an alkali agent, and the magnesium ions in the water are removed; the mine water that passes through the first regulating sedimentation tank (5) enters the oil removal sedimentation tank (6), and oil is removed by adding a demulsifier and aeration, and the iron and manganese ions in the water are removed; the water that passes through the oil removal sedimentation tank (6) enters the second regulating sedimentation tank (7), and the pH value of the water is adjusted to 7.3-7.8 by adding an acid agent, and the calcium ions in the water are removed; the sludge and ion precipitate generated in each reaction tank are discharged into the sludge concentration tank; S3: The mine water in the second regulating sedimentation tank (7) flows into the multi-media filter tank (8), where the multi-media filter layer further removes suspended solids and effectively removes iron, manganese, magnesium, calcium, sulfate and various heavy metal ions in the water; The mine water gushing through the multi-media filter tank (8) enters the disinfection tank (10), where the water is disinfected and sterilized by adding a disinfectant; the water passing through the disinfection tank (10) enters the clean water tank (11); S4: When the multi-media filter layer in the multi-media filter tank (8) needs to be backwashed, the cylinder (22) is lowered to drive the linkage mechanism (26) and the clamping mechanism (29) to be lowered as a whole, and the clamping plates (293) of the clamping mechanism (29) are driven to approach each other by the linkage mechanism (26) to clamp the multi-media filter layer that needs to be backwashed. Then, the cylinder (22) is raised to synchronously drive the multi-media filter layer to rise. When the multi-media filter layer leaves the multi-media filter tank (8), it is moved to the top of the flushing tank (9) by the transfer mechanism (21), and the cylinder (22) is lowered to place the multi-media filter layer that needs to be backwashed in the flushing tank (9). By removing the clean water tank ( The water in the multi-media filter tank (11) is transported to the flushing tank (9) for backwashing. At this time, there is still a group of multi-media filter layers in the multi-media filter tank (8) that 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, and the clamping plates (293) of the clamping mechanism (29) are driven away from each other through the linkage mechanism (26). The clamping plates (293) that are away from each other can clamp another group of multi-media filter layers, and can transport another group of multi-media filter layers to the flushing tank (9) for backwashing, thereby ensuring continuous filtering and purification of the mine water.
