Description
Technical field
The present invention relates to a kind of sewage-treatment plant, filter treatment of sewage dress particularly to a kind of mining combined multi-stage
Put.
Background technology
In mine（Colliery and metallic ore）Exploitation in, the technical process such as do mechanization operation and atomizing de-dusting will produce greatly
The waste water of amount.Suspended contamination and the microorganism such as a large amount of coal dusts, rock dust is contained in these waste water of mine, and muddy stain.
If directly discharged without processing, serious pollution can be caused to the environment near mining area, meanwhile, do mechanization operation and
The techniques such as atomizing de-dusting, require supplementation with a large amount of clean waters again.Therefore, necessary waste water of mine is carried out after purified treatment return
With.
The process of waste water of mine, has multiple different handling process.At present, the technique taken both at home and abroad mainly has following several
Kind：
1st, flocculent precipitation.Add flocculant in waste water of mine, standing a period of time, make coal dust, rock dust of suspension etc.
Impurity flocculates into big aggregate, precipitates.Then, precipitate unification is filtered.This method not only needs to use
Substantial amounts of flocculant, and treatment effect is poor, and process cycle is longer, and floor space is big, if mismanagement contains can lead to
Clear liquid can not reach the standard of direct discharge, also needs to reprocess further, and due to needing to add chemical agent, increased two
Secondary pollution；
2nd, Bubble-floating Method.By inputting certain gas in waste water of mine and combining flocculant, make the coal of suspension（Ore deposit）Powder etc. is miscellaneous
Matter is flocculated into big aggregate and is gathered in be suspended to above bubble and is removed on the water surface, and this technique floor space is little, but
Water quality is unstable, and running cost is high；Equally exist the secondary pollution problem of chemical agent；
3rd, electromagnetic separation.On the basis of flocculation sediment, using the difference of pollutant magnetic susceptibility in waste water of mine, by outer
Come magnetic field and goods and materials are carried out magnetization treatment thus reaching the technology of idetified separation.Magnetizable impurity is contained more in this technology water
Treatment effect is better, and it is little to have efficiency high, an equipment volume, the advantage of removable bacterial pathogens and partial organic substances, but work
Skill is relative complex, and operating cost is higher；
4th, membrane filter method.In the treatment of waste water, because filtering accuracy is high, the features such as flow is big, therefore, commonly used is inoranic membrane mistake
Filter.But, during mine wastewater treatment, because water mineral content is larger, and granule is thick, is easily caused membrane component and is subject to
Impact and abrasion, service life shortens.
Using the process to waste water of mine for the above-mentioned technique, there are purified treatment and down-hole purified treatment two ways on ground.
Process on the ground, need the waste water that down-hole is produced to pass through water pump lifting on ground, after being processed directly
Discharge or down-hole is returned again to for production technology by pipe special.In down-hole treatment, it is not required to waste water lifting to ground, directly
Direct reuse after being processed below mine.Obviously, direct reuse after waste water of mine being processed under mine, can not only
Reduce substantial amounts of lifting expense, furthermore, it is possible to reducing or saving the conveyance conduit expense from ground to down-hole.
In order to adapt to the needs of waste water of mine down-hole treatment, patent ZL201510115939.7 provides one kind and need not add
Any chemical agent, pollution-free, have a safety feature, control unit is simple and high degree of automation, high treating effect pottery no
Machine membrane filtration technique processes technique and the device of waste water of mine.This technology is using inorganic ceramic film as main filtration equipment；Adopt
With two-stage feed pump pattern, the water of shaft sump is pumped into cyclone separator and removes after big particle by primary pump, is directly entered nothing
Machine film process equipment, concentrates water outlet and enters circulating line, be circulated process through two stage pump circulating pump, during circulation
The 5-10% periodically discharging primary pump inflow carries out sludge condensation to sludge concentration tank, and supernatant is back to automatic filtering machine and continues
Continuous process.When the particulate matter of inoranic membrane surface accumulation reaches certain limit, by the use of compressed air as online backwash power, and
Online reverse cleaning is carried out to inoranic membrane processing equipment by the clean water in pressure water supply tank, makes inoranic membrane recover to filter work(
Energy.In order to solve the wastewater treatment demand of big flow, by multiple inoranic membrane serial or parallel connections together.In actually used process
In, this technology and technique come with some shortcomings part.Mainly in following several respects：
1st, adopt circulating pump in technique, carry out cross flow filter, in cyclic process, need to discharge the 5- of primary pump inflow
10% returns to sludge concentration tank, and in operation, power consumption is of a relatively high；
2nd, adopt Y-shaped filter in technical process, because its flow area is less, easily cause blocking.Its cleaning process needs
Manually to carry out offline, so, the system that can affect continuously is run；
3rd, waste water, after cyclone separator, is directly entered inorganic membrane filter, and the load of inoranic membrane is larger, and filtration resistance can be drastically
Increase, so that water flux is greatly reduced, for ensureing normal filtration, need frequently to clear up, thus, lead to the use longevity of inoranic membrane
Life shortens；
4th, disposal ability is low.Main cause has two aspects：First, one-level water pump pumps into the waste water of inorganic film device, has 10-15%
Return to Waste water concentrating equipment through circulating pump, this just directly influences the disposal ability of system.Secondly as not having good pre-
Filtration measure, to process the waste water higher containing particulate matter using the inoranic membrane of fine filtering, and filtration resistance rises too fast, frequently instead
Wash and need to reduce normal filtration time；
5th, the filtration resistance value of film device does not have display device, when selecting to filter and clean state, has certain blindness.
In the sewage-treatment plant in above-mentioned technique, the big particle thing in decontaminated water is removed using cyclone separator.This
Plant the cyclone separator of version, by particle size, inlet velocity, the impact of the many factors such as rotary barrel radius, effect
Rate is not high.In order to improve separation efficiency, patent ZL201420609263.8 employs one kind and by eddy flow and filters two kinds of mechanism
The device combining.In use, separation efficiency increases, but, there is also many problems：
1st, design flow deflector in the outside of taper inner core, the radius of turn of current is larger, shape is difficult to for the less current of flow
Become cyclonic action it is impossible to produce centrifugal force necessary to solid-liquid separation, do not reach due effect；
If the flow of 2 water and speed are sufficiently large, current can produce rotary motion along the flow deflector outside inner core, and eddy flow leads to
The outside in road is drainage screen, and oarse-grained silt particle because of centrifugal action, is got rid of on drainage screen with larger inertia, produce impact and
Friction, can make drainage screen produce abrasion, and, in sewage the concentration of particulate matter and solid particulate matter size increase, rotation speed
The increase of degree, abrasion plus evidence；
3rd, after the entrance of cylinder top water inlet, space becomes suddenly big to sewage, and oarse-grained silt particle can produce first in inlet water tank
Raw sedimentation, needs often to clear up.

Process, through rough calculation, every mitron road expense about 750 yuan/meter.By 1000 meters of calculating of well depth, the one-time investment of pipeline valve
Expense about needs 3,000,000 yuan.The maintenance cost of pipeline valve, needs 1,000,000 yuan every year.
C, water process expense
Using same process, on well or down-hole carries out water process, almost, expense remains basically stable equipment.
Down-hole treatment：
A, take down-hole treatment mode it is also desirable to waste water of mine is risen to certain altitude, according to using water hydraulic demand, hydraulic pressure is not
Less than 1.6 MPas, so it is not less than 200 meters in down-hole hoisting depth, design consideration rises to 300 meters.Then lifted
The electricity charge are 2.25 yuan/m3.Equally with the Design Treatment water yield as 5000m3/ d is calculated, then the annual lifting electricity charge are
5000x2.25x365=4106250 it is first.
B, carry out equipment installation in down-hole, place construction cost is more slightly higher than on ground, needs to increase by 500,000 yuan.
C, the one-time investment expense of pipeline valve reduce 2,000,000 yuan；The annual maintenance cost of pipeline valve reduces 2/3,
It is about 300,000 yuan.
Both compare:
Annual operation power charge decrement：13687500-4106250=9581250 unit.Round as 9,600,000.
Build and maintenance cost decrement：（300-200）+ 50+ (100-30)=2,200,000 yuan.
By above-mentioned calculating and contrast, according to disposal ability 5000m3/ d calculates, same handling process, in down-hole treatment
Than process on well, 15,000,000 yuan of system investments, period of recouping investments in equipment about 1 year half about.
