Abstract
The present invention provides a kind of sewage/wastewater treatment process of novel synchronous denitrogenation dephosphorizing --- Anoxic Oxic Phostrip techniques.The technique structures include denitrification reactor (anoxic), biochemical reactor (aerobic), secondary sedimentation tank, dephosphorization pond (anaerobism), mixing pit, agitating reaction pond, sedimentation basin etc..Sewage in biochemical reactor is nitrified, is absorbed the removal of phosphorus and organic matter, and denitrification denitrogenation is carried out in denitrification reactor；Secondary sedimentation tank carries out mud-water separation；Sludge rich in phosphorus enters the release that dephosphorization pond carries out phosphorus, it releases the sludge after phosphorus and flows back into denitrification reactor from bottom of pond with the sludge of replenishment system, phosphorous supernatant exits into mixing pit from dephosphorization pond top, it is synchronous to enter sedimentation basin progress mud-water separation to the solid matters such as mixing pit feeding lime or Dephosphorization reagent, the reacted generation calcium phosphate of phosphorus；The supernatant of dephosphorization flows back into the denitrification reactor of system, and a large amount of sludge rich in phosphorus are discharged, and this sludge containing high concentration phosphorus hydrochlorate can preferably use fertilizer as.
Description
Technical field
The present invention relates to sewage/wastewater processing in denitrogenation dephosphorizing field, be primarily related to sewage Microbial denitrogenation and
Chemical dephosphorization technology.
Background technology
At present, common A2/ O and inversion A2/ O synchronous denitrogen dephosphorus technologies flow is the original dirt into Biochemistry Reaction System
Water and nitrification liquid from aerobic zone reflux cycle enter anoxic zone together, and nitrate carries out anti-nitre under the action of denitrifying bacteria
Change reaction, nitrate nitrogen is converted into nitrogen, realizes the preposition denitrogenation of system；In the sludge for flowing back into anaerobic zone from secondary settling tank
PolyP bacteria the carbon source in sewage is converted into the release that ergastic substances accumulation inhales phosphorus power and carry out phosphorus；In aerobic zone, organic dirt
Dye object is further degraded, and the mineralized nitrogen in sewage is nitrate nitrogen by nitrifier, while polyP bacteria is utilized in anaerobic condition
The power of lower generation carries out excessively inhaling phosphorus；Active sludge intermixture carries out mud-water separation, a part of sludge reflux in secondary settling tank
To system front end, excess sludge of the another part rich in phosphorus is discharged from system, so as to which whole flow process realizes the mesh of denitrogenation dephosphorizing
's.A2/ O and inversion A2/ O synchronous denitrogen dephosphorus technologies use biological method during denitrogenation and dephosphorization, through processed
The content of nitrogen would generally meet national stain disease discharge standard in sewage, but the content of the phosphorus in sewage is difficult to reach national dirty useless
Water discharge standard, it is therefore desirable to find a kind of new processing method to realize synchronous denitrification dephosphorizing.
Invention content
In order to solve the problems, such as that the phosphorus content often occurred in sewage/wastewater processing does not meet state sewage emission standard, this
Invention provides a kind of novel synchronous denitrogen dephosphorus technology.The technique structures include denitrification reactor（Anoxic）, it is biochemical
Reactor（It is aerobic）, secondary sedimentation tank, dephosphorization pond（Anaerobism）, mixing pit, agitating reaction pond, sedimentation basin etc..Sewage, dephosphorizing sludge
With from biochemical reactor（Aerobic zone）The nitrification liquid of reflux cycle enters biochemical reactor after denitrification reactor carries out denitrogenation,
Sewage mixed liquor in biochemical reactor is nitrified, is absorbed the removal of phosphorus and organic matter；Treated, and sewage mixed liquor enters
Secondary sedimentation tank carries out mud-water separation, handles sewage discharge up to standard；Sludge rich in phosphorus enters in dephosphorization pond, and polyP bacteria is being detested
Phosphorus is made fully to discharge under the conditions of oxygen, sludge is sunken to bottom of pond and flows back into denitrification reactor after releasing phosphorus, and phosphorous supernatant is from dephosphorization
Pond top exits into mixing pit, synchronous to the solids such as mixing pit feeding lime or Dephosphorization reagent, the reacted generation calcium phosphate of phosphorus
Substance enters sedimentation basin separation；The supernatant of dephosphorization flows back into the denitrification reactor of system, and the sludge precipitated is discharged.It is whole
A system achievees the purpose that synchronous denitrification dephosphorizing in a manner that biological denitrificaion and chemical dephosphorization are combined；The present invention can not only be
There is in terms of denitrogenation of waste water remarkable result, and can synchronous high-efficiency dephosphorization, solve that sewage/wastewater synchronous denitrification dephosphorizing efficiency is low to ask
Topic makes sewage/wastewater discharge be easier to meet discharging standards.
Description of the drawings
Fig. 1 is the process flow chart that the present invention is implemented.
