Abstract
The present invention belongs to the field of water treatment, and relates to a new coal mine well water underground treatment process, which comprises that: (1) coal ash water generated during a coal mine tunnel mining process flows to a water bin; (2) the coal ash water being subjected to preliminary sedimentation in the water bin is pumped to inorganic ceramic membrane purification equipment through a water pump so as to be purified, the purified clear water enters a clear water bin, and the concentrated water returns to the existing water discharge facility; and (3) the clear water filtered through the inorganic ceramic membrane is pumped to a reverse osmosis desalting device through a water pump in a pressurization pumping manner so as to be subjected to desalting purification, the desalted clear water enters an underground purified water bin and is adopted as water for underground precision equipment and direct drinking water sources for mine well workers, and the desalinated concentrated water is conveyed to the ground through the existing water discharge facility so as to be treated, wherein the filtration precision of the inorganic ceramic membrane purification system is the nanometer level, and the turbidity of the clear water purified through the ceramic membrane is less than or equal to 1NTU. According to the present invention, the new process has characteristics of equipment fouling solving, equipment service life prolonging and enterprise production cost saving; and the water purified through the new process can achieve the drinking water health standard, and can directly meet the drinking water problem of the underground production line workers.
Description
Technical field
The invention belongs to water treatment field, relate to a kind of Technique of Coal Mine Drainage down-the hole treatment novel process.
Background technology
The technology of current Technique of Coal Mine Drainage down-the hole treatment has:
One, treatment technology under flocculation-sedimentation
So-called flocculation-precipitation technology is commonly called as dosing precipitation technology, namely selecting inorganic flocculating agent and organic anion to be mixed with the aqueous solution adds in waste water, just can produce compression double electric layer, makes the suspended particulates loss of stability in waste water, the mutual coagulation of micelle thing phase makes particulate increase, and forms flocs unit, alumen ustum.Flocs unit is grown up and namely depart from aqueous phase precipitation under gravity after certain volume, thus removes a large amount of suspended substances in waste water, thus reaches the effect of water treatment.For improving separating effect, coagulant aids can be added in good time, in right amount.
The advantage of flocculation sediment technology be technique simple, invest less, easy to operate, working cost is lower.But due to have floor space large, go out that water unstable, effluent quality are poor, medicament residual more than etc. shortcoming, therefore, flocculation sediment technology is generally used for qualified discharge or the preconditioning technique as advanced treatment.
Two, magnetic separation technique
Magnetic separation technique is an emerging water technology.This technology is on the basis of flocculation sediment technology, utilizes the difference of element or component magnetic susceptibility, by foreign field, material is carried out magnetic field treatment, thus reaches a kind of emerging technology of idetified separation process.Magneto separate utilizes the magnetic of impurity particle in waste water to be separated, and for the particle of non magnetic in water or weak magnetic, utilizes magnetic inoculation technique that them can be made to have magnetic.By the effect in external force magnetic field, suspended solids magnetic in waste water is separated, thus reaches the object of purifying waste water.Also there is a lot of problem in this technology simultaneously:
Although 1. magnetic separating apparatus volume is little, add traditional structures of coagulation basin supporting with it, its overall floor space is large, and underground construction difficulty, civil engineering is long in time limit, and investment cost is high.
2. coagulation basin need add flocculation agent, coagulant aids, and need add magnetic kind, and working cost is high.
3. the remanent magnetism of medium makes magnetic separating apparatus when train backlash is washed, be difficult to the magnetic-particle that adsorbs by magnetic matrix rinse well, thus affect the working efficiency of next cycle.
4. in order to improve field gradient, the magnetic matrix of high saturation must be selected, to the selection of magnetic matrix, there is certain technical difficulty, and increase working cost.
All there is dosing coagulation-settlement process in above-mentioned two kinds of techniques, effluent quality is relatively poor, can only meet downhole production general requirements: down-hole is sprayed, depositing dust.Down-hole worker's tap water cannot be met and expensive equipment (bracket support kind equipment) uses water requirement.Human factor mainly refers to that chemical feeding quantity size is by manual control, and mine carrys out hydric factor and refers to the change of the pit water water yield, the change of pit water suspension content.In these two factors, especially the change of mine water directly affects the determinative of purification system water outlet quality.Above-mentioned two kinds of automation technolo operational degrees are not high, and labour intensity is high, and changeable factor is unfavorable for automated operation.
Summary of the invention
The defect that object of the present invention overcomes prior art provides a kind of Technique of Coal Mine Drainage down-the hole treatment novel process.For realizing the object of the invention, now take following technical scheme: a kind of Technique of Coal Mine Drainage down-the hole treatment novel process, is characterized in that:
(1), the coal ash water produced in coal mine roadway recovery process is flow to sump;
(2) the coal ash water, in sump after preliminary sedimentation is pumped through water pump and is purified to inorganic ceramic film treating plant, and the clear water after purification enters clear water storehouse, and dense water comes back in existing pumping equipment;
(3) clear water, after inorganic ceramic membrane filtration is pumped through water pump pressurization and carry out desalination purification to Reverse Osmosis Desalination Process Equipment, and the clear water after desalination enters the pure sump in down-hole, as down-hole precision equipment water and mine worker direct-drinking water water source; Dense water after desalination is then delivered to ground by existing pumping equipment and processes.Described inorganic ceramic film purification system filtering accuracy is Nano grade, and the clear water turbidity after ceramic membrane purification is at below 1NTU.
Present invention process mainly refers to the expensive equipments such as hydraulic support at down-hole special equipment, need desalination in its use procedure, prevent equipment scaling from causing scrapping or affecting production and application, adopt new technology and can solve equipment scaling, improve service life of equipment, save enterprise's production cost; And the water after novel process purification can reach sanitary standard for drinking water, down-hole one line direct labor Drinking Water Problem directly can be met.
Current domestic purification of mine drainage process aspect is not also by inorganic ceramic film directly and the precedent of reverse osmosis desalination technique combination.The present invention drops into and implements to be adopted by pit water inorganic ceramic film to purify (turbidity is lower than 1NTU as tap water, ion is without exceeding standard), effluent quality can meet feed water by reverse osmosis water quality requirement (turbidity < 3, SDI < 3) completely.
