Description
Technical field
The present invention relates to the technical fields of sewage treatment, more particularly to a kind of power plant waste water processing method.
Background technique
Power plant is also easy to produce the pollutants such as raw buck, chemical wastewater, oily waste water during operation, these pollutants have
Poison, and do not have processed penetration to underground, surrounding enviroment and the people using underground water can be endangered, from long-range development mesh
From the point of view of mark, carrying out processing to the waste water that power plant generates is beneficial to long-range environmental protection and economy sight, and protects water body, in conjunction with optimization
Waste water from power plant technique and equipment realize the target of zero-emission recycling.
The method of waste water from power plant increasingly updates, and the power plant of different places takes different according to the stain disease of generation
Treatment process and equipment.Biomembrane, activated sludge process etc. is commonly used in waste water treatment plant to be handled.Waste water from power plant can be with
Utilize the advanced stain disease processing equipment for the treatment of process.For example, being used for the tubular membrane of waste water from power plant, can effectively filter useless
Water waste realizes water body non-pollution discharge, has the advantages that antipollution, acid and alkali-resistance, the operating ambient temperature that can be born is up to nine
15 degrees Celsius, it can be used for extensive and quick wastewater treatment.Waste water from power plant can use relatively advanced energy saving and suitable
Close the technique that local climate uses.
Waste Water From Fire Power Plant improvement generally can be divided into two major classes: first is that property of power plant's whole waste water by its contained pollutant
Qualitative classification centralized processing, then drains into water and stops；Second is that then draining into sewer or grey field with the processing waste water mode of dispersion.
The sewage in thermal power plant specifically includes that industrial wastewater, ash flushing water and sanitary sewage, wherein industrial wastewater is work
The general name that industry always drains, including industrial colling draining, chemical water treatment system acid-alkali regeneration waste water, filter backwash waste water,
Cleaning boiler waste water, defeated coal rinses and dust waste water, oily waste water, cooling tower blowdown water etc.；Ash flushing water is primarily referred to as being used for
The water of clinker and remover ash discharge dust is rinsed, is generally discharged after the sedimentation of grey field；Sanitary sewage refers to the dirt that power plant resident is discharged
Water.
The processing method of power plant effluent common are following several:
1, evaporation
The method evaporates the moisture of waste water gradually, forms water vapour, regelation is repeatedly sharp at water after cooling for vapor
With.In waste water from power plant, soluble solid, which is trapped within, to be steamed in raffinate, as cycles of concentration raising is finally analysed with crystal form
Out, still, directly with evaporation processing waste water, energy consumption is high, at high cost.
2, flue facture
Carrying out spray evaporation processing to waste water in flue is a kind of wider waste water from power plant method of the scope of application.Waste water with
Droplet form evaporation gasification rapidly, suspended matter and soluble solids therein after high-temperature flue gas heats form tiny solid
Then particle enters electric precipitator under the entrainment effect of air-flow and captures removal by electrode, finally realizes waste water from power plant,
But using flue facture treating capacity small, treatment effeciency is low.
3, full film water facture
What the electric desalination process in this method used is exactly electrodialytic technique, and fortune can make ion exchange resin in this way
Regeneration be achieved.The full membrane treatment process method that waste water from power plant uses at this stage mainly have reverse osmosis, ultrafiltration and
Electric desalination, and its effect is more stable, but full film water facture power consumption is big, it is at high cost.
