Description
Technical field
The utility model belongs to coal-contained wastewater processing technology field, and in particular to a kind of processing equipment of coal-contained wastewater.
Background technique
Coal-contained wastewater is when Coal Transportation System rinses the coal-contained wastewater and rainfall discharged in coal yard region and region of unloading coal
The rainwater containing coal collected, coal-contained wastewater contains very high suspended matter (mainly coal dust), since the particle of coal dust is very thin, is difficult certainly
So sedimentation.It is mostly that PAC and PAM is such as added by the way of dosing at this stage to the processing of the suspended matter in coal-contained wastewater
Deng making coal-contained wastewater after processing reaches discharge standard and reuse standard for desulfurization water, coal yard sprinkling, dry ash humidification, grey field
The Water District domain less high to water quality requirement such as sprinkling uses.
But there is also some problems for this dosing flocculation sedimentation treatment process:
(1) it to enable the suspended matter in coal-contained wastewater quickly to settle, needs that PAC and PAM is added；But coal-contained wastewater is
Stage draining, in addition seasonal rainwater containing coal, variation water quality are big, it is therefore desirable to which PAC and PAM is adjusted according to the variation of water quality
Dosage just can achieve preferable flocculating effect, and dosage is too little or too much all to reduce flocculating effect, this is managed at the scene
In be difficult to realize, to cause the water quality that is discharged after processing unstable.
(2) dosing flocculation system needs artificial dosing, the larger workload of equipment operation and maintenance.
(3) waste water through discharging after flocculation sedimentation, still contains certain suspended matter, and some is further added by a filter and sets
Standby, treated to the water outlet of flocculation sedimentation, this has accordingly increased cost, maintenance workload and occupied area.
Also have using electric flocculation treatment process and handle coal-contained wastewater, although solving the problems, such as dosing, this work
Investment cost of skill is very high.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, according to coal-contained wastewater water quality characteristics, discharge of wastewater or
Reuse requirement, provides a kind of coal-contained wastewater processing solution, the solution, and operating cost is significantly less than traditional dosing wadding
Solidifying depositing technology and electric flocculation technique.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of coal-contained wastewater processing equipment, by water
Stream direction sequence is equipped with: coal water sedimentation pond, elevator pump, silicon carbide film separation equipment and clear water with coal-contained wastewater water connection
Case；The coal water sedimentation pond is made of forebay and after-bay two parts, and the forebay has the bottom end lower than after-bay, described
The bottom end of forebay connects sludge pump by discharge outlet, and the rear bottom of pond portion is connected by water outlet with elevator pump, elevator pump
Water outlet be connected with the water inlet of silicon carbide film separation equipment, the clear water output of silicon carbide film separation equipment passes through compressed air
Delivery pipe is connected with filtered water tank, and the dope outlet of silicon carbide film separation equipment is connected by reflux line with coal water sedimentation pond.
A kind of coal-contained wastewater processing equipment, reflux line have two, are respectively communicated with forebay and after-bay.
Utility model principle
Coal-contained wastewater is unable to direct emission, it is important to contain suspended matter (the mainly coal for being largely difficult to settle in waste water
Powder), therefore, oil removal can be removed, coal-contained wastewater can discharge or reuse etc..And silicon carbide film is that flux is big, tolerance
The membrane material material products of new generation of good (full pH range is general), and there are the characteristics such as high, the wear-resistant, high temperature resistant of hardness, it can be effective
It realizes and is separated by solid-liquid separation under harsh environment.In order to achieve the above object, coal-contained wastewater needs not move through flocculation, it is directly entered silicon carbide film separation
Equipment is realized and is separated by solid-liquid separation, and the recycle-water for producing water or qualification of qualified discharge is obtained, and the concentrated water of silicon carbide film separation equipment is returned
Go back to coal water sedimentation pond.
Relatively traditional dosing flocculation sedimentation treatment process and electric flocculation treatment process, the utility model has the advantages that:
First is that without adding any medicament；Second is that effluent quality is more preferable, turbidity is in 0.5NTU or less；Third is that simple process, equipment is accounted for
Ground is small, fourth is that integrated apparatus strong shock resistance；Fifth is that integrated apparatus can fully automatic operation, without human intervention；Sixth is that
Equipment investment and operating cost are low.
Detailed description of the invention
Fig. 1 is the process flow diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model processing equipment.
Each appended drawing reference are as follows: 1-coal water preliminary sedimentation tank, 2-elevator pumps, 3-silicon carbide film separation equipments, 4-filtered water tanks,
5-sludge pumps.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Shown in referring to Fig.1, the utility model discloses a kind of coal-contained wastewater treatment process, step includes:
A), coal-contained wastewater enters coal water preliminary sedimentation tank 1, and the supernatant obtained after preliminary sedimentation enters next stage, and coal slime
After sedimentation, outlet reprocessing.
B), the solid suspension in supernatant is separated by silicon carbide film separation equipment 3, obtains qualified discharge
Water outlet or recycle-water.
C), the concentrated water after separation returns to coal water preliminary sedimentation tank 1.
As shown in Fig. 2, being for a kind of special equipment embodiment of coal-contained wastewater processing of the utility model.By water (flow) direction
Sequence is installed
4.The coal water sedimentation pond 1 is divided into forebay and after-bay two parts, and coal-contained wastewater water enters 1 forebay of coal water sedimentation pond, by
There is the bottom end lower than after-bay in forebay, after preliminary sedimentation, supernatant flows into after-bay, and the bottom end of forebay is connected by discharge outlet
Sludge pump 5, the rear bottom of pond portion are connected by water outlet with elevator pump 2, elevator pump 2 and silicon carbide film separation equipment 3 into
The mouth of a river is connected, and the concentrated water of silicon carbide film separation equipment 3 returns to coal water sedimentation pond 1, the production mouth of a river of silicon carbide film separation equipment 3 and clear
Water tank 4 is connected.Wherein reflux line has two, is respectively communicated with forebay and the after-bay in coal water sedimentation pond 1.
In conclusion the principles of the present invention are directly to realize solid-liquid point to coal-contained wastewater with silicon carbide film separation equipment
From obtain qualified discharge produces water or qualified recycle-water.The treatment process is simple, and equipment operation and energy consumption are very low.
