Description
Technical field
The present invention relates to technical field of sewage, and in particular, to a method of utilizing microbial degradation ammonia nitrogen.
Background technology
With the continuous development of society and people's living standards continue to improve, water environment is worsening, and the nitrogen in water contains
Amount, which is continuously increased, causes water quality severe exacerbation.The development of recent decades is so that rural area, the surface water in city, underground water all have three
The pollution of nitrogen (ammonia nitrogen, nitrate nitrogen and nitrite nitrogen).
Ammoniacal nitrogen is that nitrogen is primarily present form in aqueous environment.It is provided when ammonia-containing water is discharged into rivers and lakes, especially water
Source not in very sufficient river, fish pond when, receiving water body can be caused to lose oxygen, unwanted aquatic organism is grown, fish is caused to be poisoned.City
City's sanitary wastewater, the discharge water of various feed lots, septic tank lixivium, ammonia-nitrogen content is between 100~500mg/L.With
The hydrometallurgical development of non-ferrous metal, these factories often give off existing containing ammonia or ammonium waste water, ammonia-nitrogen content for high concentration
10g/L or more, some are even as high as 100g/L or so.2000 annual forest monitorings statistics indicate that, the Yellow River Ningxia enter a country section (centre halfback
Lower river bank) ammonia nitrogen concentration be no more than country《Environmental Quality Standard of Surface Water》(GZHG1-1999) requirement in providing, but reach
Control section (silver Gu highway bridge) and departure section (peaceful steel pontoon bridge) are exceeded serious, wherein silver Gu bridge highway bridge section exceeding standard rate
It is 66.7%, exceeded 2.16 times, peaceful steel pontoon bridge section exceeding standard rate is up to 100.0%, exceeded 3.20 times.Ammonia and nitrogen pollution becomes along Cheng Jiachong
Gesture is fairly obvious.In recent years, Yellow River control section (silver Gu highway bridge) ammonia and nitrogen pollution was in apparent ascendant trend year by year.Ammonia nitrogen
Having become influences the primary pollution of Yellow River.At present, Yellow River classification with V class or surpasses based on V class water quality.
Pollution of nitrate nitrogen most has become a global environmental problem in the past 40 years.Such as the U.S. states Texas
NO in the counties Runnels underground water3Content reaches 233mg/L;Britain was in NO in 19703-- N intervals are more than 113mg/L, and 1980 are about
For 90mg/L, 142mg/L is reached within 1987;BeiJing, China's nitrate in groundwater peak is 314mg/L, Shijiazhuang City underground water
Middle NO3Content is up to 20~40mg/L, peak 96mg/L.In addition there are Denmark, France, Canada, Germany, Holland, prints
The Drinking Water of the country such as degree, Egypt is also by different degrees of pollution.Some of Britain and the U.S. results of study are shown, are drunk
It is directly proportional to gastric cancer, the incidence of cancer of the esophagus and the death rate with the nitrate content of underground water.It is done in Linzhou City of Henan Province, Anyang County
Drinking water NO3Investigation of content, water sampling 43, NO in the underground water that resident drinks3Content substantially exceeds world health group
Knit drinking water quality standard 45mg/L (or the NO of (WHO) promulgation3In N be 10mg/L).Such as Anyang County one village is drunk
NO-3 contents are up to 94mg/L in underground water.
Though content of the nitrite in water body is high not as good as ammonia nitrogen and nitrate nitrogen, its harmfulness is not also small.Nitrous acid
Salt can form stable, carcinogenic and mutagenicity N-nitrosamine and nitroso under the effect of various organic compounds containing nitrogens
The various N- nitrosos compounds of group of amide.Nitrite ion can cause methemoglobinemia or baby after entering human body
Blue mass formed by blood stasis.Nitrite is the precursor for synthesizing strong carcinogen nitrosamine, and Japan, Britain, Chile, Colombia reported
Nitrite, nitrate and incidence gastric cancer rate have great correlation.Water Environment Nitrogen pollution is toxic to aquatic animals such as fish
Evil effect.The ammonia of low concentration can be interfered in water body transmits with the oxygen of the fish gill, can be to aquatic when its concentration reaches 0.5mg/L
Animal especially fish cause toxic action;Due to nitrification in water body, ammonia nitrogen will continue to be oxidized to nitrate nitrogen, and consume
The a large amount of dissolved oxygens of water body can make the aquatic animals death by suffocation such as fish when serious.Nitrogen is the indispensable nutrient of plant, but
If total N is excessive in water body, algal bloom, enrichment can be made, eutrophication occur, a large amount of dissolvings consumed in water
Oxygen makes water ecological setting deteriorate.
Everything shows that the polluted by nitrogen in water body is extremely serious, study polluted by nitrogen, and propose it is practicable improvement with
Modification measures, it has also become the task of top priority of scientific worker and government department.
The processing method of nitrogenous effluent has bioanalysis, Physical, chemical method, physical-chemical process etc. at this stage.It is most widely used
Be bioanalysis, bioanalysis is most widely used denitrogenation core technology, easy to operate because this method is at low cost, without secondary
Pollution.
By microbial degradation ammonia nitrogen, principle is:Biological denitrificaion is by nitration reaction under aerobic condition first by ammonia
Nitrogen oxidation is nitrate, then is removed nitrate reduction from water at gaseous nitrogen by the anti-nitration reaction under anoxia condition.It is raw
Object denitrogenation is completed by three ammonification, nitrification, denitrification steps.
Wherein, aminating reaction:Ammoniation refers to the process of converting organonitrogen compound to NH3-N, also referred to as mineralising
Effect.The bacterium for participating in ammoniation is known as amonifying bacteria.In nature, there are many their type, mainly have aerobic
Pseudomonas fluorescens and Bacterium prodigiosum, facultative proteus and anaerobism clostridium septicum etc..Under aerobic condition, there are mainly two types of
Degradation mode, first, the oxidative deamination under oxidase catalyzed, another is certain aerobic bacterias, can water under the catalytic action of hydrolase
Solve denitrification reaction.Under conditions of anaerobism or anoxic, anaerobe and amphimicrobe carry out organonitrogen compound
Restore deamination, hydrolytic deaminzation and the aminating reaction for being dehydrated three kinds of approach of deamination.
Nitration reaction is under the action of nitrobacteria, and ammoniacal nitrogen is further decomposed, aoxidized, with regard to this in two stages into
Row.First, under the action of nitrite bacteria, ammonia (NH4+) is made to be converted into cultured water, effect of the cultured water in Nitromonas
Under, it is further converted to nitrate nitrogen.Nitrosomas has nitrous acid zygosaccharomyces, nitrous acid Helicobacterium and nitrous acid Coccus.
Nitromonas has nitric acid Bacillus, nitric acid Coccus.
Anti-nitration reaction:Anti-nitration reaction refers to nitrate nitrogen and cultured water under the action of denitrifying bacterium, is reduced to
The process of gaseous nitrogen (N2).The bacterium for carrying out this kind of reaction mainly has Proteus, Micrococcus, pseudomonas, brood cell
The facultative bacterias such as Bacillus, alcaligenes, Flavobacterium, they are widespread in nature.
Traditional biological denitrificaion method research application time is long, technical maturity, but handles the nitrogenous effluent effect of high concentration
Unobvious, and it is of high cost.
