Description
Technical field
The invention belongs to wastewater treating technology field, more particularly to a kind of absorption and the integrated reactor system of biological nitration
System.
Background technology
With China's sustained economic development, problem of environmental pollution is but gradually serious.Industrial production and daily life produce
A large amount of waste water causes water pollution all the more serious, brings no small pressure to water environment, body eutrophication pollution becomes mesh
One of preceding main water pollution.Body eutrophication is mainly the nutriments such as N, the P discharged in being lived due to human being's production
It into slow flow water bodies such as lake, river mouth, river bends, is utilized by microorganism panning, planktonic organism is caused to accelerate breeding, makes organic matter
The phenomenon that speed of production is more than depletion rate, and water quality is destroyed, causes other biological dead.At present for how to effectively control with it is pre-
The eutrophic state of waterproof body is a most important thing for administering water environment.Complete oxidation 1mg ammonia nitrogens are probably needed for nitrate nitrogen
4.6mg dissolved oxygens are wanted, the ammonia nitrogen of high-content, which enters the slower surface water body of update, can cause eutrophication, and algae is in matrix abundance
Under conditions of raised growth breed, in the process can excessive consumption oxygen in water, lead to water so as to generate large amount of organic
Body is black smelly to seriously affect water quality, and fish can be caused dead when lacking oxygen when aquatiles.Ammonia nitrogen in water body environment is dirty
Requirement of the severe situation of dye to the treatment effect of waste water treatment process, economic benefit etc. is also higher and higher.
The basic principle of biological denitrificaion is that ammoniation of the organic nitrogen compound through ammonification microorganism is converted into ammonia nitrogen, in this base
By nitration reaction by mineralized nitrogen it is nitrite nitrogen, nitrate nitrogen, then nitrate nitrogen is converted by nitrogen by anti-nitration reaction on plinth
Gas is escaped from water, so as to achieve the purpose that denitrogenation, has the characteristics that economic, effective, easy to operate, non-secondary pollution.Absorption
Method is using having affinity physically or chemically and then the side for removing N2 adsorption between nitrogen and the larger material of specific surface area
Method, the advantage of absorption method is few occupied space, simple flow, can repeatedly utilize, will not to generate secondary pollution, suitable application region wide.
Absorption is had broad application prospects with biological nitrification and denitrification conjunctive use.Also lack at present and efficiently remove nitrogen absorber,
Meanwhile be to enhance adsorbent to the Adsorption effect of nitrogen in waste water, it needs to develop novel adsorptive reactor.It meanwhile will be anti-
The exploitation and the preparation of matched sorbing material for answering device are combined progress, and the adsorption efficiency of sorbing material is made fully to be sent out
It is one of emphasis studied at present to wave.At present, also lack and the exploitation of adsorptive reactor and adsorbent preparation are combined aspect
Research.
