The invention further relates to the preparation methods of above-mentioned bloodstone coupled biological charcoal.
The invention further relates to above-mentioned bloodstone coupled biological charcoal as biological respinse medium in processing percolate organic matter
Using.
Technical background
In the past ten years, along with the development of the lasting industry and business of many countries all over the world, house refuse
It is being quicklyd increase always with the yield of industrial solid castoff.China's domestic waste annual output is up to 2.0 hundred million tons, and with every
The speed in year 8%-10% increases, and the processing of domestic waste directly injures sustainable development, it has also become China city at present
Most one of pressing problem that Institute of Environmental Health of city faces.The various alternative disposal technologies of municipal solid wastes (are such as filled, burnt
Burning, compost etc.) comparative studies show sanitary landfills method in cost of investment and be relatively inexpensive in terms of the period.Meanwhile it defending
Raw Landfill can reduce the pollution to environment to the maximum extent, decompose rubbish under given conditions, until it is final
It is converted into metastable substance.Therefore, sanitary landfills is the first choice side for handling a large amount of house refuses and industrial solid castoff
Method, this has become global trend.
Landfill leachate is generated after rainwater is mixed by osmosis with solid waste, is that microbial biochemical process generates
The summation of water and solid waste inherently water.The water quality of landfill leachate is considerably complicated, typically contains high-enriched organics (packet
Include biodegradable component and ingredient difficult to degrade), furthermore ammonia nitrogen, heavy metal, inorganic salts are all the important components of percolate.Garbage filter
Liquid not only contaminated soil and earth surface water source, can also pollute underground water.It is existing for the removal of landfill leachate organic matter
Correlation processing technique (COD concentration range is that 2000-62000mg/L, BOD concentration range are 60-45000mg/L) general to adopt more
It is handled with biochemical method, advanced oxidation processes, but due to the biochemical difference of percolate organic matter, leading to treatment effect is not to manage very much very much
Think, and advanced oxidation processes processing cost is relatively high.
In recent years, the degradation that organic pollutant in anaerobic environment is carried out using alienation Fe (III) reduction process, is repaired in biology
Multiple field has certain application prospect.For organic pollutant in landfill leachate, alienation Fe (III) reducing bacteria can
Using organic pollutant as electron donor, Fe (III) is used as electron acceptor, along with having while Fe (III) biological reducing
The mineralising of machine object.For bloodstone as one of Fe (III) ferriferous oxide widely distributed on the earth, scientific circles have bloodstone biology
The correlative study of deoxidization, degradation organic pollutants in water body, and the usual reaction condition of this reaction process is more harsh or is limited to
The problems such as thermodynamic stability height of bloodstone and poor bioavailable property, causes oxidation operation rate whole slower.
Bloodstone biological reducing process removes the organic matter in landfill leachate, the process can by artificial ligand or
Electron shuttle body is strengthened, and this substance rich in quinonyl ingredient of charcoal, can effectively facilitate going back for organic compound
Originality degradation.A large amount of quinonyl and phenolic hydroxyl group functional group ingredient are had been detected by charcoal at present.This unique structure is special
Sign can make charcoal that can serve as electron shuttle body during redox reaction, accelerate Fe (III) reducing bacteria and bloodstone
Between electron transport rate, and then promote organic matter anaerobic oxidation effect effect, reach quickly removal water body organic contamination
The purpose of object.
