Description
Technical field
The present invention relates to one kind water body is realized using multistage upflow-type reactor（Such as lake, river, reservoir, pond etc.）
The apparatus and method that nitrogen and organic matter synchronously remove.The apparatus and method can effectively realize Water element and organic matter
It is synchronous to remove, reduce 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 producing 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 in addition to 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, its oxidant is ferric iron, and ammonia is oxidized to nitrate, and ferric iron is reduced to two
Valency iron.Therefore iron can 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
Utilized by denitrifying microorganism.
Plant dry branches and fallen leaves is predominantly filled and burned as the general solid waste in city, common disposal options, landfill
The percolate of high organic concentrations can be produced, burning can have an impact atmospheric environment.The dry branches and fallen leaves of plant is in decomposable process
Organic matter can be produced, 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 produced 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, so as to fulfill the recycling of solid waste.
