Description
Technical field
The utility model is related to a kind of water body (such as lake, river, reservoir, pond are realized using multistage upflow-type reactor
Pool etc.) nitrogen removal synchronous with organic matter device.The device can effectively realize that Water element and organic matter synchronize
It removes, reduces that surface water body is black smelly and outrophication risk.
Background technology
Water body nitrogen includes inorganic nitrogen and organic nitrogen, and inorganic nitrogen is mainly ammonia nitrogen, nitrite and nitrate.At present can
Realize that the process that ammonia nitrogen is converted into nitrogen removal is Anammox, but Anammox needs nitrite as oxygen
Agent, nitrite are easily aoxidized, and natural water body content of nitrite is relatively low, and control ammonia by modulation process operating parameter
Oxidation residence is extremely difficult in the Nitrification Stage for generating nitrite, therefore realizes natural water body by anaerobic ammonia oxidation process
The removal of nitrogen is difficult to realize.Inorganic nitrogen usually exists with ammonia nitrogen and nitrate salts in natural water body, therefore by first will
Ammoxidation is nitrate, then realizes ammonia nitrogen and nitrate removal compared with anaerobism ammonia oxygen for nitrogen nitrate reduction through denitrification process
Change process is easy to implement.
The biological oxidation process of ammonia, can also be by some with metal oxide other than it can be aoxidized by aerobic ammonia-oxidizing bacteria
For the microbiological oxidation of electron acceptor, such as ferriferous oxide and Mn oxide.Iron oxidation ammonia is newfound in recent years can to detest
The microbial process of ammonia is aoxidized under the conditions of oxygen, oxidant is ferric iron, and ammonia is oxidized to nitrate, and ferric iron is reduced to two
Valence iron.Therefore can iron be aoxidized ammonia process to couple with denitrification process, realizes water body ammonia nitrogen and nitrate removal.Denitrification mistake
Journey is needed using organic matter as electron donor, and organic matter mainly exists in the form of hardly degraded organic substance in natural water body, it is difficult to
It is utilized by denitrifying microorganism.
Plant dry branches and fallen leaves is predominantly filled and is burned as the general solid waste in city, common disposal options, landfill
The percolate of high organic concentrations is will produce, burning can have an impact atmospheric environment.The dry branches and fallen leaves of plant is in decomposable process
Organic matter is will produce, the organic matter of generation can grow for heterotrophic microorganism provides carbon source and the energy, therefore can be used as anti-nitre
The carbon source of chemical industry skill.The dry branches and fallen leaves that municipal gardens are generated is used for denitrification process, can both reduce the processing of dry branches and fallen leaves
Cost can also reduce influence of the processing procedure to environment, to realize the recycling of solid waste.
Existing natural water body treatment technology majority is by aeration mode or combines biological floating bed, nano material, wetland real
Existing water body nitrogen and organic matter removal, although aeration can remove the Organic oxidation in water body, but by ammonium oxidation
For nitrate, and the removal of ammonia nitrogen is not implemented；Although the biological floating bed removal that can realize nitrogen on the basis of beautifying landscape,
But plant falls off the water body content of organic matter can be caused to increase, and nitrogen removal rate is relatively low；Emerging nano material technology
(such as nano zero valence iron) is although can realize that nitrogen removal synchronous with organic matter, the production cost of nano material are higher；
Although structure wetlands ecosystems can realize the removal of nitrogen and organic matter, the general floor space of wetland is larger, occupies
Land resource.Mainly being aerated with by way of carrier adsorption, aeration is for aerobic heterotrophism for the removal of organic matter in natural water body
Microorganism provides the oxidation that oxygen realizes organic matter, and technique energy consumption is higher；Carrier adsorption effect by carrier performance determine, and
Organic matter also needs to carry out advanced treating after absorption.
