Description
Technical field
The utility model is related to a kind of sewage-treatment plant, at more particularly to a kind of mining combined multi-stage filtering effluent sewage
Reason device.
Background technology
In mine（Colliery and metallic ore）Exploitation in, the technical process such as do mechanization operation and atomizing de-dusting will be produced greatly
The waste water of amount.Contain suspended contamination and the microorganisms such as a large amount of coal dusts, rock dust, and muddy stain in these waste water of mine.
If without treatment directly discharged, 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, it is necessary that waste water of mine is carried out to return after purified treatment
With.
The treatment of waste water of mine, there is various different handling process.At present, the technique taken both at home and abroad mainly has following several
Kind：
1st, flocculent precipitation.Flocculant is added in waste water of mine, a period of time is stood, makes coal dust, the Rock Powder of suspension
The impurity such as dirt flocculate into big aggregate, precipitate.Then, sediment unification is filtered.This method not only needs
Using substantial amounts of flocculant, and treatment effect is poor, and process cycle is more long, and floor space is big, if mismanagement contains can lead
Causing supernatant can not reach the standard of direct discharge, also need further reprocessing, and due to needing to add chemical agent, increase
Secondary pollution；
2nd, Bubble-floating Method.By to being input into certain gas in waste water of mine and combining flocculant, making the coal of suspension（Ore deposit）Powder
Big aggregate is flocculated into Deng impurity to be gathered in above bubble and be suspended on the water surface and be removed, this technique floor space
It is small, 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, borrow
Help extraneous magnetic field carries out magnetization treatment so as to reach the technology of idetified separation by goods and materials.Contain magnetizable impurity in the technology water
More multiprocessing effect is better, small with efficiency high, equipment volume, can remove the advantage of bacterial pathogens and partial organic substances,
But technique is relative complex, 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, generally using being inorganic
Membrane filtration.But, during mine wastewater treatment, because water mineral content is larger, and particle is thick, is easily caused membrane element
Part is hit and weares and teares, and service life shortens.
Treatment using above-mentioned technique to waste water of mine, there is purified treatment and underground purified treatment two ways on ground.
On the ground treatment, it is necessary to the waste water that underground is produced by water pump lifting on ground, after being processed directly
Discharge returns again to underground 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 the mine.Obviously, direct reuse after being processed under mine waste water of mine, can not only
Substantial amounts of lifting expense is reduced, furthermore, it is possible to reduce or save the conveyance conduit expense from ground to underground.
The need in order to adapt to waste water of mine down-hole treatment, patent ZL201510115939.7 provides a kind of without addition
Any chemical agent, it is pollution-free, have a safety feature, control unit is simple and high degree of automation, the ceramic nothing of high treating effect
The technique and device of machine membrane filtration technique treatment waste water of mine.The technology is using inorganic ceramic membrane as main filtration equipment；Adopt
With two-stage supply-water pump pattern, after the water of shaft sump is pumped into cyclone separator removing big particle by primary pump, nothing is directly entered
Machine film process equipment, concentration water outlet enters circulating line, treatment is circulated by two stage pump circulating pump, during circulation
Periodically the 5-10% of discharge primary pump inflow carries out sludge condensation to sludge concentration tank, supernatant be back to automatic filtering machine after
Continuous treatment.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, inoranic membrane is recovered filtering 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, the technology and technique come with some shortcomings part.Mainly in following several respects：
1st, circulating pump is used in technique, cross-flow filtration is carried out, it is necessary to discharge primary pump inflow in cyclic process
5-10% returns to sludge concentration tank, and power consumption is of a relatively high in operation；
2nd, Y-shaped filter is used in technical process, because its flow area is less, blocking is easily caused.It was cleaned
Journey needs manually to carry out offline, so, system can be influenceed continuously to run；
3rd, after waste water is through cyclone separator, inorganic membrane filter is directly entered, the load of inoranic membrane is larger, filtration resistance meeting
Sharply increase, water flux is greatly reduced, to ensure normal filtering, it is necessary to frequently clear up, so that, cause making for inoranic membrane
Use the lost of life；
4th, disposal ability is low.Main cause has two aspects：First, one-level water pump pumps into the waste water of inorganic film device, there is 10-
15% returns to Waste water concentrating equipment through circulating pump, and this just directly influences the disposal ability of system.Secondly as without good
Pre-filtering measure, processed using the inoranic membrane of fine filtering containing particulate matter waste water higher, filtration resistance rises too fast, frequency
Numerous backwash needs to reduce normal filtration time；
5th, when the filtration resistance value of film device does not have display device, selection filtering and cleaning state, with certain blindness
Property.
In sewage-treatment plant in above-mentioned technique, using cyclone separator except the big particle thing in decontaminated water.This
The cyclone separator of structure type is planted, by particle size, inlet velocity, the influence of many factors such as rotary barrel radius, effect
Rate is not high.In order to improve separative efficiency, patent ZL201420609263.8 employs a kind of by two kinds of mechanism of eddy flow and filtering
The device for combining.In use, separative efficiency increases, but, there is also many problems：
1st, flow deflector is designed in the outside of taper inner cylinder, the radius of turn of current is larger, and the current less for flow are very
Hardly possible forms cyclonic action, it is impossible to centrifugal force necessary to producing separation of solid and liquid, does not reach due effect；
If the 2, the flow and speed of water are sufficiently large, current can produce rotary motion, rotation along the flow deflector on the outside of inner cylinder
It is screen pack on the outside of circulation road, the silt particle of bulky grain is got rid of on screen pack because of centrifugal action with larger inertia, produces punching
Hit and rub, can make screen pack produce abrasion, also, in sewage the concentration of particulate matter and solid particulate matter size increase, rotation
The increase of rotary speed, abrasion plus evidence；
3rd, after sewage enters through cylinder top water inlet, space becomes suddenly big, and the silt particle of bulky grain can first in inlet water tank

C, water process expense
Using same process, on well or underground carries out water process, almost, expense remains basically stable equipment.
Down-hole treatment：
A, down-hole treatment mode is taken, it is also desirable to waste water of mine lifting to certain altitude, according to using water hydraulic demand, water
Pressure is not less than 1.6 MPas, is so not less than 200 meters in underground hoisting depth, and design considers lifting to 300 meters.Then
The lifting electricity charge are 2.25 yuan/m3.Equally with design treatment water as 5000m3/ d is calculated, then the annual lifting electricity charge are
5000x2.25x365=4106250 units.
B, equipment installation is carried out in underground, construction cost ratio in place is slightly higher on ground, it is necessary 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,
About 300,000 yuan.
Both compare:
Annual operation power charge decrement：13687500-4106250=9581250 units.Round is 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 is calculated, same handling process, in down-hole treatment
Than being processed on well, 15,000,000 yuan of system investments, period of recouping investments in equipment about 1 year half or so.
