Description
Technical field
This utility model relates to green technology, is specifically related to domestic sewage treatment device.
Background technology
Human lives's sewage, is one of the primary pollution source of water body.Mainly feces and wash water.The sanitary sewage amount that city is discharged everyone every day is 150 400L, and its amount and living standard have substantial connection.Containing large amount of organic in sanitary sewage, such as cellulose, starch, saccharide, fat and protein etc.；Also pathogen, virus and parasitic ovum are often contained；The chloride of inorganic salts, sulfate, phosphate, bicarbonate and sodium, potassium, calcium, magnesium etc..Total feature is nitrogenous, sulfur-bearing and phosphorous height, under anaerobic bacteria effect, and easily raw odorant.
Existing sanitary sewage disposal technical development is started late, dominating process route such as:
BAF: process dress exactly in biofilter and center filler, by artificial oxygen supply, make to grow substantial amounts of microorganism on filler.This sewage treatment process device is made up of filter bed, distribution device, water-distributing device, drainage arrangement etc..Aerator adopts supporting special aeration head, and the middle minute bubbles of generation cut repeatedly through filler, reach the effect close to micro-control aeration.Owing in reaction tank, sludge concentration is high, treatment facility is compact, can be greatly saved floor space, reduces the response time.
SBR dephosphorization process: body eutrophication main cause be the mankind to discharge into water substantial amounts of ammonia nitrogen and phosphorus, the main factor of phosphorus body eutrophication especially.Making a general survey of domestic waste water processes technique, dephosphorization technique is always up the difficult problem that puzzlement sewage treatment plant runs.Traditional materialization phosphorus removal technology needs substantial amounts of medicament, has operating cost height, the shortcoming that sludge yield is big；The Biological Phosphorus Removal Processes of preposition anaerobism has an advantage that operating cost is low, but taking the photograph phosphorus, release phosphorus effect due to the microorganism that places one's entire reliance upon, it is difficult to reach the requirement of country's sewage treatment process.When considering Treated sewage reusing, then it is more difficult to reach requirement.
But due to the settlement dispersion of samll cities and towns of China, source of sewage distributed points volume is few, and the scale of cities and towns level Sewage Plant is many lower than 10000 ton per days.Current domestic large-and-medium size cities sewage treatment plant through frequently with sewage treatment process have traditional activated sludge process, A2/O, SBR, oxidation ditch etc., if the operating cost remained high can be caused by with these technology buildings Small Town Wastewaters treatment plant, it is impossible to properly functioning.Therefore must adopting reduced investment for the feature of samll cities and towns, operating cost is low, consistent reliably, operation with manage relatively simple process and corresponding equipment.
Existing equipment: as shown in CN101269880A, being suitable for the little occasion of the scale treating capacity such as samll cities and towns and use, disposal ability is also better.But equipment volume and integration are still good not, and mud delivery ratio is cumbersome.Or the cylindrical process device disclosed in CN101391834A, this device is the cylindrical shape of inside and outside two-layer, and integration is better, but internal structure is excessively complicated, and fragmenting plate ladder is more, and operation stability is poor, and clean and maintenance is pretty troublesome.CN201240939Y also discloses that a kind of columnar process device, but the process route of its setting is simple, and device specification volume is little, also without extended capability, so disposal ability is little, and poor practicability.
It would therefore be highly desirable to a kind of disposal ability of exploitation is strong, can be suitably used for the occasion that sewage quantity fluctuation is big；Stable, installation cost is low, domestic sewage treatment device easy to use.
