Nothing in this specification should be construed as requiring a specific three dimensional orientation of structures in order to fall within the scope of the invention.
Referring to fig. 1, a system schematic of a mine water treatment system according to the present invention is representatively illustrated. In this exemplary embodiment, the mine water treatment system proposed by the present invention is described by taking an example of application to treatment of mine water. Those skilled in the art will readily appreciate that various modifications, additions, substitutions, deletions, or other changes may be made to the embodiments described below in order to utilize the concepts of the present invention in other types of water treatment processes, and still remain within the scope of the principles of the mine water treatment system as set forth herein.
As shown in fig. 1, in the present embodiment, the mine water treatment system provided by the present invention includes a water collection module 100, a pretreatment module 200, and a deep treatment module. Specifically, the water collecting module 100 is disposed in a downhole space of a mine to collect water to be treated and lift the water to the ground. The pretreatment module 200 is arranged on the ground, a water inlet of the pretreatment module 200 is communicated with a water outlet of the water collection module 100, and the pretreatment module 200 is used for pretreating water to be treated. The advanced treatment module comprises a reverse osmosis membrane device 310, and the reverse osmosis membrane device 310 is a disc tube type or disc type reverse osmosis membrane device. The reverse osmosis membrane device 310 is arranged in the underground space, a water inlet of the reverse osmosis membrane device 310 is communicated with a water outlet of the pretreatment module 200, and a water outlet of the reverse osmosis membrane device is communicated with a water using module of a mine, so that the pretreated water after pretreatment is desalted, the mineralization of the effluent is reduced, and micromolecular organic matters, viruses, bacteria and the like are removed. Accordingly, at least a part of the water inflow driving force of the reverse osmosis membrane device is generated by the height drop of the pretreated water conveyed to the underground space through the ground. Through the design, the mine water treatment system provided by the invention has the advantages that the pretreatment module 200 and the disc-tube or disc-type reverse osmosis membrane device 310 are respectively arranged on the ground and the underground space, the water inlet driving force of the reverse osmosis membrane device 310 is generated by utilizing the height difference of the pretreated water conveyed to the underground space from the ground, the high energy consumption requirement of the reverse osmosis membrane device 310 is met, the additional booster pump is not needed to provide the water inlet driving force, the operation cost is saved, and the initial investment is reduced. In addition, the disc tube type or disc sheet type reverse osmosis membrane device 310 has the characteristics of higher pressure grade and concentration multiple, better effluent quality, stable separation performance and the like. On the basis of ensuring that the recovery rate and the desalination rate of the mine deep treatment reach the standard, the invention utilizes the environmental characteristics of the mining area, simplifies the system, improves the operation and maintenance of the equipment and realizes the efficient and energy-saving desalination treatment.
It should be noted that, in combination with the depth of the well of the existing mine and the water inlet driving force required by the reverse osmosis membrane device 310, the power of the pretreated water generated by the height difference between the pretreatment module 200 and the reverse osmosis membrane device 310 can completely meet the requirement of the water inlet driving force of the reverse osmosis membrane device 310, and therefore, a booster pump is not required to be arranged at all. Of course, in other embodiments, when the water inlet driving force of the reverse osmosis membrane device 310 needs to be increased, or when the downhole depth of the depth treatment module is small, the power of the pretreated water generated by the height difference between the pretreatment module 200 and the reverse osmosis membrane device 310 can still partially meet the requirement of the water inlet driving force of the reverse osmosis membrane device 310, thereby reducing the energy consumption of the booster pump.
Alternatively, in this embodiment, the advanced treatment module may comprise a reverse osmosis membrane device 310 of a disk tube type or a disk type. Through the design, because the reverse osmosis membrane device 310 of disc tube type or disc type has the characteristics of high pressure resistance and pollution resistance, the requirement on the quality of inlet water can be reduced, and the pollution blockage is not easy to generate during operation, the reverse osmosis membrane device is more suitable for the underground working environment of a mine, so that other pretreatment devices do not need to be additionally arranged underground, the cost and the maintenance difficulty of the whole system are reduced, and the operation condition is improved. In addition, the membrane of the disc tube type or disc type reverse osmosis membrane device 310 can be replaced independently, and the membrane column can be reused, so that the service life of the equipment is prolonged.
It should be noted that, based on the design that the advanced treatment module includes the disk tube type or disk sheet type reverse osmosis membrane device 310, the treatment principle of the pretreated water treated by the pretreatment module 200 in the disk tube type or disk sheet type reverse osmosis membrane device 310 mainly includes: the water to be treated is treated by the ground pretreatment module 200 to become pretreated water, the pretreated water is input into a system feed inlet of a disc tube type or disc type reverse osmosis membrane device 310 and is pumped into a membrane column of the disc tube type or disc type reverse osmosis membrane device, and an additional pretreatment device does not need to be arranged in the underground area of a mine. Specifically, the separation component of the disc-tube or disc reverse osmosis membrane device 310 adopts an open flow channel, pretreated water flows to the other end of the device through a channel between a flow guide disc and a shell of the disc-tube or disc reverse osmosis membrane device 310, the pretreated water enters the flow guide disc through a plurality of channels at a flange at the other end, the pretreated water rapidly flows through a filter membrane at the shortest distance, then reverses to the other membrane surface by 180 degrees, and then flows into the next flow guide disc from a notch at the center of the flow guide disc, the pretreated water forms a double S-shaped path of 'circumference → circle center → circumference → circle center' on the surface of the reverse osmosis membrane, the pretreated water flows through the surface of the reverse osmosis membrane under the pressure effect, forms turbulence due to collision of salient points, so that the permeation rate of the pretreated water and the self-cleaning effect of the reverse osmosis membrane can be improved, and concentrated solution flows out from the flange at the feeding end, the produced water after membrane separation can be used for water using devices of mines. For example, the water utility may comprise an emulsion pump station, and the desalinated water from the advanced treatment module may be at least partially used as a pressure fluid for the emulsion pump station.
Further, based on the design that the advanced treatment module includes the disc-tube-type or disc-type reverse osmosis membrane device 310, in this embodiment, the disc-tube-type or disc-type reverse osmosis membrane device 310 may include multiple sets of membrane modules and a PLC control cabinet. In the case where the reverse osmosis membrane device 310 of the disk type or the disk type includes 10 sets of membrane modules, the treatment capacity of the device for treating pretreated water may be about 20 tons/day, and the water inlet pressure may be about 5 Mpa.
Alternatively, as shown in fig. 1, in this embodiment, the water collection module 100 may include a sump 110 for storing sediment in the mine downhole gushes and sediment gushes. On this basis, the water inlet of the water sump 110 may be located at the lowest point of the roadway elevation of the bottom yard of the mine, and the water outlet may be communicated with the pretreatment module 200 through the water pump 121.
Further, as shown in fig. 1, based on the design that the water collecting module 100 comprises the water sump 110 and the water pump 121, in the present embodiment, the water pump 121 may be disposed in a pump sump 120 of the downhole space. The suction well 122 of the pump chamber 120 is connected to the water outlet of the water chamber 110, and the water outlet of the pump chamber 120 is connected to the pretreatment module 200. On the basis, the pump chamber 120 and the water chamber 110 can be respectively formed by two relatively independent mutually-impermeable roadways of the underground space, and the capacities of the pump chamber 120 and the water chamber 110 can be determined according to the water inflow of the mine.
Further, as shown in fig. 1, based on the design that the water collecting module 100 includes the sump 110, in the present embodiment, a dredging device may be disposed in the sump 110 for periodically dredging the sump 110 and cleaning the sediment such as silt in the sump 110.
Alternatively, as shown in fig. 1, in the present embodiment, the mine has a subline shaft 400, and the water outlet of the water collection module 100 is communicated with the water inlet of the pretreatment module 200 through a pre-water inlet pipe 410, and the water outlet of the pretreatment module 200 is communicated with the water inlet of the advanced treatment module through a pre-water outlet pipe 420. On this basis, a pre-entry water pipe 410 and a pre-exit water pipe 420 may be respectively disposed in the auxiliary shaft wellbore 400. In other embodiments, when the mine has the auxiliary shaft wellbore 400, only the pre-water inlet pipeline 410 may be disposed in the auxiliary shaft wellbore 400 and the pre-water outlet pipeline 420 may be disposed in other shafts, or only the pre-water outlet pipeline 420 may be disposed in the auxiliary shaft wellbore 400 and the pre-water inlet pipeline 410 may be disposed in other shafts, which is not limited to this embodiment.
Alternatively, as shown in fig. 1, in the present embodiment, the pretreatment module 200 may include a conditioning tank 210, a reaction tank 220, a sedimentation tank 230, and a clean water tank 240. Specifically, the inlet of the regulating reservoir 210 is connected to the outlet of the water collecting module 100, and the regulating reservoir 210 is used for homogenizing the quality and quantity of the water to be treated. The water inlet of the reaction tank 220 is communicated with the water outlet of the regulating tank 210. The reaction tank 220 is connected with a first chemical adding device 221, the first chemical adding device 221 is used for adding a flocculating agent into the reaction tank 220, and the reaction tank 220 is used for the flocculating agent to perform a flocculation reaction with water to be treated. The water inlet of the sedimentation tank 230 is communicated with the water outlet of the reaction tank 220, and the sedimentation tank 230 is used for separating impurities from the water to be treated. The water inlet of the clean water tank 240 is communicated with the water outlet of the sedimentation tank 230, and the water outlet of the clean water tank 240 is communicated with the water inlet of the advanced treatment module. The clean water tank 240 is connected to a second chemical adding device 241 for adding a disinfectant to the clean water tank 240. Compared with the existing design, the mine water treatment system provided by the invention can meet the pretreatment requirement of the whole system only by arranging the pretreatment module 200 on the ground.
It should be noted that, based on the design of the pretreatment module 200, compared with the prior art, the pretreatment module 200 adopted in the present invention can only comprise the conventional coagulation sedimentation pretreatment scheme, thereby removing suspended matters in the water to be treated. Because the disc-tube or disc-type reverse osmosis membrane device 310 adopts an open flow channel design, compared with a common reverse osmosis membrane component, the device can resist high pressure and pollution, does not need a complex pretreatment device, can reduce the chemical operation cost of the membrane, has long cleaning period and small occupied area, and is easier to maintain and prolong the service life of the filter membrane under a mine with relatively severe conditions.
Further, as shown in fig. 1, based on the design that the pretreatment module 200 includes the conditioning tank 210, in the present embodiment, a first stirring device 211 may be disposed in the conditioning tank 210. The first stirring device 211 can only stir the water to be treated transferred into the conditioning tank 210 to uniform the quality and quantity of the water to be treated.

A plurality of second stirring devices 222 may be disposed in the reaction tank 220, and the second stirring devices 222 may be spaced along the flow direction of the water to be treated in the reaction tank 220, so as to sufficiently mix the flocculating agent with the water to be treated. On the basis, along the above flow direction, the stirring rotation speed of the second stirring devices 222 is gradually reduced to prevent the alum flocs formed by the reaction of the water to be treated and the flocculant from being broken up, thereby improving the settleability of suspended matters in the water to be treated.
Further, as shown in fig. 1, based on the design that a plurality of second stirring devices 222 are disposed in the reaction tank 220, in the present embodiment, the plurality of second stirring devices 222 may be arranged in an alternating height distribution manner. Specifically, for any two adjacent second stirring devices 222, the two second stirring devices 222 may be arranged to be offset in the height direction. Through the above design, the stirring of the second stirring devices 222 is more uniform and sufficient, and the reaction effect of the flocculation reaction is further optimized.
Further, as shown in fig. 1, a partition 223 may be disposed between two adjacent second stirring devices 222 in the present embodiment, based on the design that a plurality of second stirring devices 222 are disposed in the reaction tank 220.

Through the design, the length of the flowing path of the water to be treated in the reaction tank 220 can be prolonged, and the reaction effect of the flocculation reaction is further optimized.
Further, as shown in fig. 1, three or more second stirring devices 222 may be provided in the reaction tank 220 in the present embodiment, depending on the design in which the plurality of second stirring devices 222 are provided in the reaction tank 220. On this basis, when the partition plates 223 are provided between two adjacent second stirring devices 222, the partition plates 223 are two or more, and these partition plates 223 may be alternately arranged in sequence, for example, alternately up and down. Specifically, taking the second stirring devices 222 as three examples, in the flow direction of the water to be treated, the partition 223 between the first second stirring device 222 and the second stirring device 222 may be connected to the bottom of the reaction tank 220, the top of the partition 223 may be spaced from the top of the reaction tank 220 for the water to be treated to flow through, the partition 223 between the second stirring device 222 and the third second stirring device 222 may be connected to the top of the reaction tank 220, and the bottom of the partition 223 may be spaced from the bottom of the reaction tank 220 for the water to be treated to flow through. Through the design, the flow path of the water to be treated in the reaction tank 220 is approximately in a plurality of continuous S-shaped bent paths, the length of the flow path of the water to be treated in the reaction tank 220 is further prolonged, and the reaction effect of the flocculation reaction is further optimized.
In addition, as shown in fig. 1, a third partition plate 223 is provided on the downstream side of the third second stirring device 222 in the flow direction of the water to be treated. In other words, the partition 223 is not necessarily disposed between two adjacent second stirring devices 222, and may be disposed only on one side of two second stirring devices 222 at the upstream and downstream ends, and is not limited to this embodiment.
Further, as shown in fig. 1, based on the design that the pretreatment module 200 includes the sedimentation tank 230, in the present embodiment, the sedimentation tank 230 may be an inclined plate sedimentation tank 230. Wherein, an inclined plate 231 and an overflow groove 233 can be arranged in the sedimentation tank 230, and a sludge discharge device is arranged at the bottom of the tank. Accordingly, the water to be treated after the flocculation reaction in the reaction tank 220 flows through the inclined plate 231 from bottom to top in the sedimentation tank 230 to separate impurities such as precipitates in the water to be treated, and the clear liquid after the separation of the water to be treated overflows into the overflow tank 233 through the clear water region above the inclined plate 231, and the water outlet of the sedimentation tank 230 may be disposed in the overflow tank 233, for example, the tank bottom or the tank wall of the overflow tank 233.
