Description
Technical field
The invention belongs to technical field of sewage, design a kind of device utilizing microorganism electrochemical to process sewage
And method, particularly relate to utilize microorganism electrochemical to process the industry of low concentration carbon source ultrahigh concentration ammonia nitrogen and life dirt
The device and method of water, and microbial film cultural method.
Background technology
Ammonia nitrogen waste water is mainly derived from chemical fertilizer, coking, petrochemical industry, pharmacy, food, refuse landfill etc..Life
Ammonia nitrogen in sewage is essentially from toilet sewage discharge.A large amount of ammonia nitrogen waste waters enter water body and not only cause water body rich
Nutrient laden, causing black and odorous water, the difficulty of Water purification and added cost, even to crowd and biological produce poison
Evil effect, has the various process of bioanalysis, physico-chemical process for the process technique (before 2014) of ammonia nitrogen waste water
Technique etc..Growth is developed rapidly, the high ammonia nitrogen produced therefrom now with the industry such as chemical fertilizer, petrochemical industry
Waste water also becomes one of industry development restraining factors；It is reported, calendar year 2001 China marine site occurs red tide to be up to 77
Secondary, ammonia nitrogen is one of major reason of pollution, the pollution that particularly high-concentration ammonia nitrogenous wastewater causes.Therefore the world
In the range of sewage treatment plant all in the method attempting to look for can effectively processing high concentration ammonia nitrogen sewage.How warp
The effective high density pollution that controls of Ji also becomes the important topic of current environmental worker research, has obtained people in the industry
The great attention of scholar.
Generally processing method has physico-chemical process and biological denitrificaion method.Wherein physico-chemical process comprises blow-off method, zeolite denitrogenation
Method, membrane separation technique, magnesium ammonium phosphate sediment technology, chemical oxidization method.Biological denitrificaion method comprises tradition and newly opens
The denitrification process sent out has A/O, two sections of activated sludge processes, Strong oxdiative Aerobic biological process, short-cut nitrification and denitrification,
Ultrasonic stripping processes ammonia nitrogen method method etc..CN203890087U discloses at a kind of air stripping blow-off method ammonia nitrogen recovery
Reason device.Gas blow-off method stripping ammonia out is utilized to be reclaimed by water absorption plant, after recovery again
Ammonia just can become other the chemical products containing ammonia again by processing.The method is not accomplished without harm
Reason, needs to add absorbing liquid and absorbs the ammonia given off, add operating cost.CN 103537264 A
Disclose a kind of adsorbent for Low Concentration Ammonia Containing Wastewater process and preparation method thereof.Absorption described in invention
Agent is high only for ammonia nitrogen absorption capacity, absorption is stable, regeneration is convenient, and overcome blow-off method, biological denitrificaion method,
Activated Zeolite Adsorption and chemical precipitation method are in shortcoming present on cost and nitric efficiency.But, this invention is the most uncomfortable
By the disposal ability of high concentration ammonia nitrogen sewage.
Compared to physico-chemical process, biological denitrificaion method is low due to investment and operating cost, simple to operate and non-secondary pollution,
The advantages such as discharged wastewater met the national standard is highly reliable, therefore become the optimum treatment mode of denitrogenation.Biological denitrificaion is exactly profit
With extraordinary microorganism, the ammonia nitrogen dissolved in degraded water body also forms harmless nitrogen gas effusion water body, thus reaches
The purpose processed to polluted water purification.The ammonia nitrogen that bioanalysis is removed in water body mainly uses microorganism nitrification
And denitrification process.Nitrifying process is nitrobacteria ammonia nitrogen formation nitre under conditions of aerobic, in oxidation water body
Hydrochlorate or nitrite；Denitrification process be denitrifying bacteria when anoxia, utilize in water body organic
Nitrate or nitrate reductase, as electron donor, are become nitrogen by thing.Generally, it is considered that nitrifying process is whole
A process important during individual ammonia nitrogen degradation, process is slow, completes difficulty higher.It is primarily due to
Nitrobacteria belongs to autotroph, including nitrous acid Pseudomonas (nitrosomonas) and nitric acid Pseudomonas
(nitrobacter).Two class bacterium are obligate aerobic organism, all using oxygen as final electron acceptor in oxidizing process,
Utilize DIC, it is common that carbon dioxide is as unique energy source.
Traditional biological denitrificaion processing procedure, is first under aerobic condition, and ammonium oxidation is sub-by Nitrosomas
Nitrate nitrogen, then cultured water is further oxidized to nitrate nitrogen by Nitromonas.The most under anoxic conditions, anti-nitre
Change bacterium and nitrogen as nitrate or nitrite is reduced into gaseous nitrogen.Although conventional waste water biological denitrification process is eliminating nitrogen
Pollution aspect serves certain effect, but still there are the following problems:
(1) Autotrophic nitrification bacterium is under conditions of large amount of organic exists, to the competition of oxygen and nutrient substance not
Such as aerobic heterotrophic bacteria, thus heterotrophic bacteria is caused to be preponderated；Denitrifying bacterium is using Organic substance as electron donor, and has
The existence of machine thing affects the speed of nitration reaction；DO concentration is needed difference very by nitration reaction and anti-nitration reaction
Greatly.The different requirement of above-mentioned nitrifier and denitrifying bacterium result in two two processes of nitrification and denitrification in the time
Spatially it is difficult to unified.
(2) the nitrobacteria metabolism time is long, and reproduction is very slow, and growing environment is harsher, a lot of under the conditions of cannot
Get the mastery in growth competition with heterotroph microorganism.Some common nitrous acid strains averagely to take 26
Hour could breed one times, and the cycle of nitric acid strain reproduction is longer, averagely to take 60 hours and could breed
One times.Nitrifying bacteria community growth rate is slow and is difficult to maintain higher biological concentration, particularly in low temperature winter.Cause
This causes system total hrt longer, and organic loading is relatively low, adds capital expenditure and operating cost.
(3) for maintaining higher biological concentration and obtaining good denitrification effect, it is necessary to carry out sludge reflux simultaneously
Reflux with nitrification liquid, add power consumption and operating cost.
(4) ammonia nitrogen removal needs the existence of enough organic carbon sources completely.And generally high-ammonia-nitrogen sewage does not contains
Have or containing a small amount of organic carbon source.
(5) biological denitrificaion is not appropriate for the process of high-concentration ammonia nitrogenous wastewater.Mainly due to ammonia nitrogen in high density pair
The impact of microbiologic population.It has been generally acknowledged that ammonia nitrogen in high density has inhibitory action to the activity of microorganism.
