Description

A kind of Desulphurization for Coal-fired Power Plant wastewater zero discharge system and method
Technical field
The present invention relates to Desulphurization for Coal-fired Power Plant field of waste water treatment, and in particular to one kind is applied to Desulphurization for Coal-fired Power Plant waste water Zero discharging system and method.
Background technology
Coal-burning power plant is the rich and influential family of China's industrial water, and its water consumption and displacement are very huge, about 40% in industrial water For coal-burning power plant, the annual discharge capacity in coal-burning power plant accounts for the 10% of national industrial enterprise's discharge capacity.Coal-burning power plant is given up in China The research of water harnessing is started late, but with environmental protection relevant law and supervises more and more stricter, coal-burning power plant's waste water " zero-emission Put " it is mentioned more and more.
Promulgate within 2006《Waste Water From Fire Power Plant Treatment design technical regulation》Explicitly point out, the desulfurization wastewater of thermal power plant Treatment facility will be separately provided, and paid the utmost attention to treatment for reuse, do not set floss hole, it is necessary to realize waste water zero emission.In April, 2015 Issue《Water pollution action plan》Pointing out, country will strengthen the management of all kinds of water pollutions, control pollutant emission comprehensively, Desulphurization for Coal-fired Power Plant waste water causes industry to be paid close attention to because of complicated component, containing heavy metal.What in November, 2016 put into effect《Control pollutant Discharge permit embodiment》Even more take the lead in pointing out to thermoelectricity, paper industry enterprise core hair pollutant discharging license.Same month, State Council Issue《" 13 " ecological environmental protection is planned》, it is indicated that pollutant should be greatly reduced in the highly water intensive industry such as electric power, papermaking, printing and dyeing Intensity is discharged, reaches advanced norm standard.On January 11st, 2017, Chinese Ministry of Environmental Protection prints and distributes again《Thermal power plant's pollution prevention technique political affairs Plan》.
In recent years the environmental protection policy of the intensive issue of government department shows that the Party Central Committee, State Council pay much attention to ecological environmental protection Work, pressure of the thermal power plant as water consumption rich and influential family in terms of Water Resources Restriction with discharge limitation suddenly rise, accelerate to implement Depth is economized on water and effluent sewage " zero-emission " turns into inevitable choice.With the continuous progress of green technology and the leather of environmental protection concept Newly, some coal-burning power plants being on the forefront start to be laid out in advance, made rational planning for, and do not stint and substantial contribution is put into environmental protection.But i.e. Just in this way, the domestic coal-burning power plant for really realizing waste water zero emission is still very few at present.
Study carefully its cause, on the one hand, due to the difficulty in treatment of coal-burning power plant's waste water zero emission --- desulfurization waste water quality has Have turbidity is big, hardness is high, content of beary metal is high, chloride ion content superelevation, easy fouling, it is perishable the features such as, intractability is big;Separately On the one hand, the existing desulfurization wastewater Treatment process generally used, the performance in reliability, economy are unsatisfactory on the market.Example Though such as three header technology techniques of most of power plants' uses are simple before this, investment cost is relatively low, full factory's waste water " zero can not be met The environmental requirement of discharge ".
Currently, domestic thermal power plant desulfurization wastewater " zero-emission " technology is summed up still in research and development and Preliminary Applications stage Mainly there are two process routes:One is the process route for being realized in a manner of water process " zero-emission ", i.e. " pretreatment softening+film Concentrate decrement+evaporative crystallization " technology.The technology is more ripe, stable, has part successful operation case and not to power plant Generating production has any impact, but its investment and operating cost are too high, and more solid waste is also easy to produce in processing procedure, this Containing toxic components such as chlorion, sulfate radicals in a little solid waste, separating treatment again is also needed to before being recycled after reclaiming, Increase cost, cause the unmanned recovery of the solid waste after present coal-burning power plant's exhaust-gas treatment, reduce the performance of enterprises;Another is The process route of " zero-emission " is realized in a manner of fume afterheat, i.e. " pretreatment+flue spray drying " technology.Its advantage is investment It is relatively low with operating cost, but technology also unshaped, waste water evaporation is incomplete, easily causes corrosion and dust stratification to block to flue, at present Impacted there has been no successful operation case and to power plants generating electricity production.
