Description
Technical field:
The present invention relates to a kind of environmental protection technical field sewage biological treatment system biological film suspend carrier.
Technical background:
The body of carrying out a biological disposal upon in the biochemical system is a sewage, and the pollution symptom of water dirt can be a physical property, also can be chemical, also may be biological.The water body of occurring in nature generally all has certain self-purification capacity, when the pollutent amount of entering of source of pollution more after a little while, water body can make Pollutant levels descend gradually by self-purification, thereby is returned to original state.The self-cleaning of water body is meant mainly in the water body that organism and part inorganics are become inorganicss such as carbonic acid gas, water, nitrogen, phosphorus by microbiological degradation under aerobic or anaerobic condition, a part is discharged in the air and goes, a part is absorbed by plant, algae, makes water body peace and quiet thereby reduced Pollutant levels.But in population and industrial high concentration, the area of science and production high development, the pollutent that enters water body has substantially exceeded the self-purification capacity of water, particularly the various chemical substances of the synthetic that do not have originally of nature are received in the water body, destroyed original ecological balance, made water be subjected to serious day by day pollution.When the water quality severe overweight, may force plant downtime, stopping production, crop failure, total crop failure, near the obvious increase of resident's Expectancy meeting some severe contamination district etc., even all disputes of water pollution causing, become the important factor that influences social stability, therefore, water environment treatment becomes the current slow great item of compeling not allow.
Organism in the sewage is the most important composition that causes water to pollute, and it exists in the mode of suspended substance, colloid thing or dissolved organic matter in water, is that the waters is rotten, blackout, smelly root.Therefore the processing of organic matter of sewage is very crucial in the process of protection environment and control pollution, and in general biological process (aerobic, anaerobism) is a most economical effective means of removing Organic pollutants in the sewage.
The biological process kind is many in sewage treatment process, as: activated sludge process, the SBR method, the AB method, oxidation ditch process, fluidized bed process, bio-disc system, contact oxidation method, microbial film moving-bed method etc., wherein biomembrance process is a comparatively active subject of present sewage treatment area, particularly the development of sewage treatment area technology in recent years focuses mostly on the biomembrance process treatment process, and the biological moving bed sewage treatment has more technological advancement, the BOD clearance reaches more than 95%, the COD clearance reaches more than 85%, water outlet BOD can reduce to below the 10mg/L, has the function of dephosphorization denitrogenation simultaneously.Be the protection environment, make the preferred version of sewage recycling.
The core technology of biological moving bed sewage treatment process is a microbial membrane carrier.The biofilm carrier product is more both at home and abroad at present, as: Pall ring column suspending carrier, ladder ring-type suspending carrier, riser column suspending carrier, multiaspect hollow ball shape suspending carrier, combined suspension carrier etc., these carriers are owing to be subjected to the restriction of physique structure, specific surface area is all less, at 72～460m
2/ m
3Between, effective ratio area is at 44～270m
2/ m
3Between, microbial film area coverage deficiency influences sewage treating efficiency.In addition, select materials mostly is resins such as PE, PP, and the microbial film biofilm cycle is longer, need 15～90d under the normal temperature, when sludge loading is high, BOD＞2500mg/L, microbial film thickness is greater than 2mm, even reach 3mm, carrier intracavity space deficiency easily causes microbial film to stop up, and dissolved oxygen is difficult to penetrate microbial film, and anerobe is active, the accumulation of anaerobic digestion products such as organic acid, ammonia and hydrogen sulfide influences effluent quality.Simultaneously also because microbial film thickens, carrier proportion increases, when carrier proportion greater than 1 the time, carrier sinks, and piles up at the bottom of the pond, directly has influence on the sewage treating efficiency of system, can make the total system paralysis when serious, can't normally move.
Summary of the invention:
All less in order to overcome traditional suspending carrier specific surface area, microbial film area coverage deficiency, select materials and physique structure are improper, and the microbial film biofilm cycle is longer, easily cause microbial film to stop up, the accumulation of anaerobic digestion product, carrier sinks, and influences the defective of sewage treating efficiency, the invention provides a kind of biological film suspend carrier, 1) improves carrier physique structure, increasing specific surface area; 2) solid support material is carried out modification, make microbial film thickness moderate; 3) biofilm carrier is by the preferred microorganism instruction, and the biofilm carrier biofilm cycle after the instructionization is shortened, for the safe operation of biochemical system with reach the high quality effluent index favourable condition is provided.
The technical scheme of the key technical problem that the present invention solves is:
1) the biological film suspend carrier body adopts round tube shape structure, the cross stiffening web is set in the pipe, the carrier surfaces externally and internally is tiny irregular convex-concave fluctuating shape fiber crops line, has increased biomembranous sticking power, competent intracavity space for microorganism adhere to and existence provides supremacy clause.Biological film suspend carrier specific surface area S＞800m after the improvement
2/ m
3, the microbial film area coverage has increased by 2～6 times than conventional carriers.Biological film suspend carrier outer wall after improvement is provided with many flow deflectors, when the aeration lifting force impacts in biological film suspend carrier is subjected to the aeration tank, under the effect of flow deflector, free-floating moves with the circling round upset of water body in the aeration tank, increase the chance of microbial film contact organism and absorption dissolved oxygen, improved biodegradability.
2) biological film suspend carrier is the matrix material manufacturing that is become to be grouped into by macromolecule resin and inorganic active, by the carrier that this matrix material is made, and wall thickness 0.4～0.5mm, proportion d=0.97～0.98g/cm
3, the microbial film strong adhesion, thickness is moderate.Material selection: PE, PP or PS resin 57～80wt.%, and add clinoptilolite 1～25wt.%, hard lime carbonate 2～15wt.%, activated carbon 1～10wt.%, diatomite 1～15wt.%, coke powder 2～10wt.% etc., extrusion moulding, manufacture craft is easy.
3) biological film suspend carrier in oxidation pond by (according to processed sewage composition preferred microorganism bacterial classification) after the inoculation of preferred microorganism instructionization, carry out vacuum lyophilization, freeze-drying process is to allow moisture reach the exsiccant purpose from freezing (solid) state direct gasification (distillation), to keep mud original activity and natural essence, air-tight state is preserved down.
