Work process containing coal waste water treatment process
(1) precipitation process
Enter in the sedimentation tank containing coal Waste Water Treatment containing coal waste water, carry out preliminary sedimentation, to remove bigger coal dust
Granule and partial suspended thing.And reduce concentration of suspension further by after micropore ceramics filter block coarse filtration.
(2) coagulating process
Being promoted in effluent treatment plant by coal water elevator pump containing coal waste water after preliminary sedimentation tank precipitates, simultaneously before device
Adding inorganic coagulant and organic coagulant aid, enter in the lump in effluent treatment plant, the eddy flow in effluent treatment plant is centrifuged
Disengagement zone, medicinal liquid and waste water mixing, and gradually form alumen ustum and bigger floc sedimentation, gradually sink under gravity and centrifugal action.
(3) centrifugal separation processes
After waste water enters effluent treatment plant, first enter eddy flow centrifugal separating area with tangential way, make the downward eddy flow of water,
Under the influence of centrifugal force, the granule eddy flow more than 20um is made to sink down into the gravity settling separation district in purifier.
(4) gravity settlement process
After the granule more than 20um is separated in purifier, the granule less than 20um under the effect of medicament gradually
Forming floc sedimentation, floc sedimentation is gradually increased in a dynamic state, when increasing to a certain degree, sinks rapidly under the effect of lower spin, under
Heavy speed is more than static subsidence velocity, the sludge condensation district in particles sink to purifier.
(5) dynamic filtration process
When waste water filtering layer in purifier, particle diameter is dammed substantially at the granule of more than 5um, to guarantee water outlet
Water quality.Water after filtering is discharged by top outlet pipe behind clear water zone again.
(6) sludge condensation process
Granule enters the sludge condensation district in purifier, makes mud rapid concentration under the effect of eddy flow power and static pressure,
Periodically or continuously discharge.
(7) produce water depth to filter
Fibrous nodules is utilized to have great specific surface area and voidage.Produce water and enter fiber ball filter, when filtering work
Owing to filtrate is flexible, filtrate and hole are compressible, and along with operating pressure and the deadweight of filtrate when filtering, filtering layer space is along current
Direction tapers into, loose lower fine and close ideal distribution state in formation；Thus the impurity such as the float effectively dammed in water, fall
Low delivery turbidity and float.
(8) drying slime utilizes
Because of containing the impurity in coal waste water based on small-particle coal powder, remove after moisture still recoverable, system arranges row
Coal slime in preliminary sedimentation tank is periodically cleared up and is recycled to re-use after coal yard carries out dry in the sun by car mud scraper.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
