Description
Technical field
The present invention relates to a kind of Membrane Bioreactor for Wastewater Treatment methods of denitrating flue gas demercuration, belong to environmental technology field.
Technical background
Nitrogen oxides is to form a series of rings such as acid rain, photochemical pollution, depletion of the ozone layer and city haze weather
The important root of border problem, Mercury In The Air have persistence, property easy to migrate and height bioconcentration and cause global concern, it is right
Human health and ecological environment all cause to seriously endanger.Artificial source annual mercury emission in China's is 500~700t or so, is more than complete
The 25%~30% of ball anthropogenic discharge amount, 2010 are 538 tons；Nitrogen-containing oxide and mercury flue gas be mainly derived from coal-burning power plant and
Industrial Boiler, metal smelt and cement kiln, mercury are classified as global contaminant by United Nations Environment Programme；China's nitrogen in 2014
Emissions of oxides total amount is 20,780,000 tons.First part of the national joint signature in 140, the whole world in 2013 legally binding
International treaties " Minamata mercury prevents and treats pact ", it is intended to reduce global mercury emissions.2005 U.S. environment general administration (EPA) announced clear
The control standard of clean air plan-mercury, China " fossil-fuel power plant atmospheric pollutant emission standard " (GB13223-2011) and " boiler is big
Gas pollutant emission standard " (GB 13271-2014) defines power plant and middle and small burn coal boiler flue gas mercury and mercuric compounds are arranged
Put standard.China is maximum coal production in the world and consumes state, and the ownership of boiler and the quantity of boiler manfacturing producer are
The first in the world.Industrial Boiler in 2012 has reached 62.4 ten thousand, year energy-output ratio be probably in 6.4 hundred million tons of mark coals.2013
China's " prevention and control of air pollution action plan " requires to accelerate ten measures such as Flue Gas Denitrification Engineering transformation, makes every effort to promote air quality and changes
It is kind.China's atmosphere pollution at present is serious, will be in face of the dual reduction from international environment diplomatic negotiations and domestic economy development
The pressure of mercury and discharged nitrous oxides.The improvement of gas mercury and nitrogen oxides is extremely urgent, it has also become at present in the world by pass
Infuse the research hotspot of frontier nature.Absorption method adsorbent is easily saturated, generates hazardous waste etc. two in existing gaseous mercury processing technique
Catalyst used in catalysis method is expensive in secondary pollution, denitrating flue gas demercuration technology, and the two operating cost is high, and bioanalysis
Have many advantages, such as that operating cost is low, without secondary pollution and be easily managed, has become world industry waste gas purification forward position research heat
Point.
Using denitrifier by NO under conditions of anaerobism or anoxicxIt is reduced to harmless N2, in denitrifying bacterium removal flue gas
NO, oxygen concentration are denitrifying key factors, and study denitrification removal NO dynamics, will lead to centre when nitrate is excessive
Product N2The accumulation of O influences the removal rate of NO, handles nitrogen oxides in 50 ± 1 DEG C of high-temperature biological drop filter tower aerobic denitrifications.Cigarette
Mercury in gas is divided into Elemental Mercury (Hg0), oxidation state mercury (Hg2+) and particle mercury (HgP), the wherein more difficult removal of Elemental Mercury, is cigarette
The difficult point of bicycle pump contamination control.Coal-fired flue-gas bivalent mercury can be removed using wet type desulfurizing denitrification apparatus, deduster such as electric precipitator,
Sack cleaner removes particle mercury；Active carbon particle is sprayed into fire coal boiler fume removes Elemental Mercury, but the technical fee mistake
Height, economy are poor.Conversion using microorganism to metal can handle mercury fume, mercury-containing waste water and repair mercury contaminated
Soil environment has become the research hotspot of international environmental protection.Hg0Biological oxidation: mainly include microbial body in hydrogen mistake
The catalysis of the enzymes such as oxidizing ferment and catalase carries out Hg0Oxidation, aerobic soil bacteria such as bacillus, streptomycete etc. have
Stronger Hg0Oxidability.Gaseous elementary mercury can efficiently be removed using the bio-trickling filter denitrification of sulfide-oxidizing enzyme biofilm.Using
The matrix of the biological prosthetic divalent mercury pollution of filamentous fungi Aspergillus flavus strain KRP1, flavus strain
KRP1 goes the bivalent mercury in water removal by biosorption mechanism.
