Description
[technical field]
The utility model relates to the biologic treating technique field of water treatment, specifically biological bed treatment unit under a kind of 360 degree of rotating waters.
[background technology]
In water technology, biological sewage treatment is the general name of disposing of sewage by biological method, is one of method the most widely in Modern sewage process application.Decomposition mainly by microorganism is converted into simple inorganics dirty Organic substance in water, and sewage is purified.By can be divided into anaerobic biological treatment and the large class of Aerobic biological process two to oxygen demand situation.Anaerobic biological treatment system utilizes anaerobion that organism is converted into organic acid, and methanobacteria is decomposed into methane, carbonic acid gas and hydrogen etc. organic acid again, as the anaerobic digestion and anaerobic biological reactor etc. of anaerobic pond, septic tank, mud.Aerobic biological process system adopts mechanical aeration or natural aeration (producing oxygen etc. as algae photosynthesis) to provide the movable energy for aerobic microbiological in sewage, promote the decomposition active of aerobic microbiological, sewage is purified, as the function of active sludge, biological filter, blodisc, sewage irrigation, oxidation pond.Biological sewage treatment is effective, and expense is low, and technology is comparatively simple, and Application comparison is convenient.
When simple precipitation and chemical treatment can not ensure to reach enough degree of purifications, will make to utilize the metabolic function of microorganism by the method for the biology conventional bioremediation in sewage disposal that is for further processing, the organic substance decomposing in sewage being dissolving or colloidal state is oxidized to stable inorganic substance, sewage is purified, and conventional has activated sludge process, biomembrance process, A/O method, A
2/ O method, A/B method, SBR method etc., different sewage disposals adopts different treatment processs, and because sewage quantity is large, organic content is high, is difficult to stabilizing treatment, thus, must reform and innovate.
In sewage disposal, conventional bioremediation has:
1, A/O method
Anaerobic Methods in Treating economizes energy consumption, but degree for the treatment of does not reach actual requirement.Aerobic treatment energy consumption is large, can meet processing requirement.After process, final product is different, and anaerobic treatment is that useless Organic substance in water is converted into ammonia, hydrogen sulfide, methane etc.Aerobic treatment is that Organic substance in water is converted into stable inorganics (carbonic acid gas is main).Anaerobism can process high-concentration waste water, and aerobic treatment is unable to undergo high-concentration waste water slug.Current most of wastewater treatment all adopts anaerobism (anoxic), aerobic combination technology.
2, activated sludge process
Activated sludge process, also known as suspension growth method, is a kind of most widely used aerobic treatment technique, and it is primarily of aeration tank, aerating system, secondary sedimentation basins and sludge recirculation system composition.The active sludge refluxed bottom waste water and secondary sedimentation basins enters aeration tank simultaneously, and by aeration, active sludge is suspended state and fully contacts with waste water.Suspended solids in waste water and gelatinoid are by activated sludge absorption, and the dissolved organic matter in waste water is used as the nutrition of self-reproduction by Microbial Communities in Activated Sludge, and metabolic conversion is biomass cells, and is oxidized to final product carbonic acid gas.Non-solubility organism first need be converted into dissolved organic matter, is then just utilized by metabolism, and waste water is purified thus.Waste water after purification and active sludge carry out mud-water separation in secondary sedimentation basins, and supernatant liquor discharges, and the sludge part after separation returns to aeration tank, and to ensure certain density active sludge in aeration tank, all the other are then as excess sludge removal system.
3, biomembrance process
Biomembrance process, also known as fixed growth method, is a class waste water aerobic biologic treating technique arranged side by side with activated sludge process.The essence of this treatment process is: the carrier surface flowing that the waste water containing nutritive substance is having microorganism to perch, and after certain hour, microbes is attached to carrier surface increment, growth, forms the membranaceous biological sludge of one deck---microbial film.Organic Pollutants in Wastewater, as nutritive substance, by the microorganism panning on microbial film, waste water is purified, and microorganism self also obtains procreation increment.The more biomembrance process of current application refers to contact biological oxidation process.
4, contact oxidation method
Processing efficiency is high, saves and takes up an area.Biological contact oxidation process as biomembrance process not only has the feature of activated sludge process concurrently, and its unit volume biomass specific activity mud is many, and biological activity is high; The mass transfer velocity of substrate and product is fast; Do not need to cultivate bacterial classification specially, biofilm is convenient, can intermittent operation; Simple to operate, run conveniently, be easy to maintenance management, without the need to sludge reflux, do not produce sludge bulking phenomenon; Mud generation is few, and mud granule is comparatively large, is easy to precipitation; Impact load has stronger adaptive faculty, and under intermittent operation condition, appoint and can keep good treatment effect, the enterprise uneven to draining, has more practical significance.
In current domestic and international biologic treating technique research and development, the research emphasis of biologic treating technique be increase treatment unit containing dirty ability, improve flow velocity, improve effluent quality, secondly simplify the operation, improve the level of automatization and operate continuously.
The patent No. be 201310201212.1 Chinese patent disclose filter bed device and filter method under a kind of 360 degree rotating waters of intaking, that filter bed device is arranged at below horizontal plane, pipe core is provided with drive unit and some filtering units, drive unit drives filtering unit centered by pipe core, do 360 degree of rotations, adopt physical method to rely on waterhead, filter, but this filter method is not good to filter effects such as microorganisms.
