In system, water quality is most complicated, pollute the water body of most serious.Desulfurization wastewater contains the float of high concentration, high chlorine root, high salinity, height
Concentration heavy metal, environmental pollution are extremely strong, therefore desulfurization wastewater zero-emission is imperative.
At present, desulfurization wastewater zero-discharge technology is broadly divided into evaporative crystallization and goes out salt technology and heat smoke evaporation technique.Evaporation
Crystallize out salt technology and need to be softened and be concentrated etc. pretreatment to desulfurization wastewater, as desulfurization wastewater hardness is high, complicated component, because
This softens and concentration technology investment operating cost is higher, and fluctuation of service.Subsequent evaporation crystallization investment high energy consumption is big, and
It is higher to front end pre-processing requirements, otherwise easily fouling and clogging, producing crystal salt cannot be processed.Heat smoke evaporation technique is equally needed
The pretreatment such as soften and concentrate, pretreatment investment operating cost is higher, and follow-up smoke evaporative is sprayed using original flue
Evaporation, it is impossible to which solve waste water is thoroughly evaporated problem, and dust deposit in flue is serious, it is impossible to steady in a long-term to run, has a strong impact on unit
Stable operation.
After the discharge of included simple desulfurization wastewater treatment system in conventional wet lay sulfur removal technology, i.e. desulfurization wastewater first
Through three header medicine systems (adding lime cream, sodium hydroxide, organic sulfur, flocculant, flocculation aid etc.), depositing reservoir is subsequently entered
Precipitation after flocculation is separated with clear water.But muddy water can not be processed by the method, equally exist the problem of Treatment of Sludge simultaneously.
And pretreatment investment operating cost is higher, evaporative crystallization investment high energy consumption is big, easily fouling and clogging, and producing crystal salt cannot locate
Reason.
