Description
Technical field
The present invention relates to sewage treatment field more particularly to a kind of collection Ao Baoer, biological multiplication, the more first chemical industry of MBBR, MBR
Skill is in the sewage treatment pot of one.
Background technique
Sewage treatment is to make sewage reach the water quality requirement of draining and to the process that sewage is purified, sewage treatment quilt
It is widely used in the every field such as building, agricultural, traffic, the energy, petrochemical industry, environmental protection, medical treatment, food and drink, classifies by sewage source, it is dirty
Water process is generally divided into production sewage treatment or sanitary sewage disposal, and shows the sewage treatment of sanitary sewage disposal in the art
Tank, processing capacity is low, and effluent quality is poor, takes up a large area.
The settable three ditches form of Pall oxidation ditch technique, respectively outer fissure, middle ditch, septal fossula, volumetric ratio are generally 50:
33:17, control dissolved oxygen concentration is respectively 0mg/L, 1mg/L, 2mg/L, is not shunted mainly for rain dirt, and municipal sewage is intake not
It is stable and setting, " simultaneous nitrification-denitrification " can occur to a high degree, there is preferable denitrification effect, can effectively solve agriculture
The unstable problem of village's wastewater influent.
Biological multiplication process is a kind of Novel sewage treatment process of Germany's invention, using low dissolved oxygen (usual 0.3-
0.5mg/L) realize that short distance nitration/denitrification denitrogenation, high sludge concentration (usual 5-8g/L) ensure to handle high-efficiency continuous stabilization, it is raw
Object multiplication process has efficient biological denitrificaion and good phosphor-removing effect, and maintenance workload is small, and occupied area is small, throws
Money, operating cost are low.
Siphon technique of backflow, water system water supply end pressure are reduced or are generated caused by negative pressure (vacuum or partial vacuum)
Reflux, has the characteristics that motorless.
It is big to recycle the mud mixture in pond body in biological multiplication process than a times circulation dilution technology, it recycles
Flow is tens times even thousands of times of flow of inlet water, since the polluter in water body is with water circulation, by microorganism
It gradually degrades, so that pollutant concentration is lower in circulation end, so that the pollutant concentration in water inlet reduces rapidly, effectively avoids
Microorganism is subjected to impact, and provides stable water body environment for microorganism growth.
It is micro- to mix close exposure, dissolved oxygen, sludge concentration are effectively controlled, so that short-cut nitrification and denitrification is smoothly realized, energy conservation
While reduce the system residence time.In addition high sludge concentration improves the capacity of resisting impact load of system.
MBBR technique improves biomass and biological species, to improve processing by adding a certain number of suspending carriers
Efficiency.Since packing density is close to water, so when aeration, with water in the state that is thoroughly mixed, the ring of microorganism growth
Border is gas, liquid, solid three-phase.The collision and shear action of carrier in water, keep air bubble more tiny, increase the benefit of oxygen
With rate.In addition, all having different biological species inside and outside each carrier, some anaerobic bacterias of growth inside or facultative aerobe, outside are
Aerobic bacteria, carrier each in this way are a microreactor, exist simultaneously nitration reaction and anti-nitration reaction, to improve
Treatment effect.
MBR membrane bioreactor replaces traditional biological processing technique end secondary settling tank with membrane module, in the bioreactor
High activity sludge concentration is kept, biological treatment organic loading is improved, to reduce sewage treatment facility occupied area, and passes through guarantor
It holds low sludge loading and reduces surplus sludge volume.The main work using in the membrane separation plant entrapping tank being immersed in aerobe pond
Property sludge and larger molecular organics.Activated sludge (MLSS) concentration can be promoted to 8000 ~ 10 in membrane bioreactor system,
000mg/L, it is even higher；Sludge age (SRT) can extend to 30 days or more.
Hollow winding process is formed by extrusion molding+sizing+Mechanical entanglement processes, with corrosion-resistant, intensity is high, heat preservation is anti-
Make an uproar, energy conservation and environmental protection the characteristics of, be conducive to the generation and culture of red bacterium in sewage disposal process.
Therefore, developing a kind of integrated sewage treating apparatus for combining above-mentioned any several techniques is to have extremely
Large market.
Summary of the invention
