Description
Technical field
The utility model belongs to engineering field, relates to the arrangement in a kind of spontaneous evaporation pond, is applied to large-scale indirect air cooling fuel-burning power plant desulfurization wastewater emission treatment.
Background technology
The waste water of wet desulfurization of flue gas by limestone-gypsum method system mainly adopts medicaments such as adding lime slurry, organosulfur to carry out oil removal, heavy mental treatment scheme.The main processing technological flow of desulfurization wastewater is as follows:
The main place to go of desulfurization wastewater has after treatment: 1, directly discharging, 2, Ash Removal System, 3, desalination-low-flash are processed.Adopt directly discharging, reuse Ash Removal System and reverse osmosis desalination-low-flash to process existing problems as follows:
1. direct emission scenary:
Waste water after the processing still exists a small amount of heavy metal ion mercury, cadmium, micro-Ni to exceed standard, and the sulfide trace exceeds standard, and fluorochemical, muriate high-content exceed standard, and the suspended substance high-content exceeds standard, organism BOD, COD high-content exceed standard.Directly discharge rear water body to discharging and soil to slight pollution.
2. be back to use the Ash Removal System scheme:
For saving the consumption of fresh water, reduce the water consumption index in recent years, the scheme of waterpower ash-slag delivery system is substantially inapplicable in the power plant in water shortage in north china area, all adopts the dry ash conveying system, and ash-slag disposal system adopts wet method.
After desulfurization wastewater entered ash-slag disposal system, heavy metal ion was separated out with sedimental form in the pulp water system of alkalescence; Fluorochemical, muriate are separated out with the crystal of degree of supersaturation after circulating for several times and concentrating, and fluorochemical, chloride concentration maintain a stable concentration value.The reason that the lime-ash water pollutant can too much not increase is exactly that the hydrolysis of CaO active in the lime-ash has been played desulfurization wastewater has been carried out secondary lime treatment effect.Directly enter dragveyer such as desulfurization wastewater, slag removing system increases anti-corrosion measure to dutiable value: 1,000,000 units increase by 800,000 yuan, 600,000 units by every unit and come the row budgetary estimate by 600,000 yuan of every units, 300,000 machines by 400,000 yuan of every units.If the pulp water system is huge, the then corresponding increase of expense.
3. desalination-low-flash is processed:
Reach the liquid zero emission requirement, in the existing water technology, two kinds of technology of evaporation pond and evaporative crystallizer are arranged, select the evaporative crystallizer technology.The investment of evaporative crystallizer and running cost is unusual height all.Reduce if can will enter the dense water of evaporative crystallizer, the investment of whole dense water treatment and running cost will reduce greatly.Reduce the water yield of dense water, existing best technology is reverse osmosis technology, but reverse osmosis has very high requirement to influent quality, meets RO water inlet requirement as long as strong brine processed, then can reduce in a large number the rate of recovery that the concentrated water discharge water yield improves RO, and obtain high-quality RO product water.The haline water recovery system adopts the technology of UHR+ evaporative crystallizer.System process is as follows:
Dense water equalizing tank → first order reaction (case) pond → second order reaction (case) pond → third order reaction (case) pond → concentration basin → TMF lift pump → TMF(micro-filtration) system → TMF produces water tank → dense water RO lift pump → 5 μ m cartridge filter → high-pressure pump → dense water reverse osmosis → product water tank+dense water tank → evaporative crystallizer.
Internal system TMF(micro-filtration) device backwash draining and dense water reverse osmosis unit cleaning draining all is back to system entry and accomplishes recycling; Crystal behind the evaporative crystallization can landfill disposal, and the mud that system produces is considered comprehensive utilization with other mud in the factory.
