Description
Technical field
The utility model relates to a kind of water body processing apparatus, relates in particular to a kind of water body high-efficient denitrification and dephosphorization device, belongs to water-treatment technology field.
Background technology
Along with economic fast development, the dirty waste water of a large amount of Nitrogen-and Phosphorus-containings that produce in industrial production and agricultural production process enter in river, lake, storehouse, cause water body nitrogen and phosphorus content too high and finally cause the generation of body eutrophication.At present, the conventional equipment of removing nitrogen phosphorus exists many deficiencies on the market, as: simultaneously denitrogenation dephosphorizing, need additionally add carbon source and meet denitrification denitrogenation needs; Also need additionally to add alkaline matter and ensure the balance of soda acid in reaction system; Mud-water separation weak effect etc.The method of conventional biological carbon and phosphorous removal is that two processes of denitrogenation and dephosphorization are completed respectively in different structures (device) mostly, the result of doing like this cause exactly technical process complexity, structures floor space large, consume energy greatly, poor processing effect etc.
Utility model content
For the weak point in addressing the above problem, the utility model provides a kind of water body high-efficient denitrification and dephosphorization device.
For solving above technical problem, the technical solution adopted in the utility model is: it is made up of a kind of water body high-efficient denitrification and dephosphorization device water-in, primary sedimentation pond, submerged blodisc, common blodisc, biological filter and water outlet;
Water-in, primary sedimentation pond, submerged blodisc, common blodisc are connected in order from left to right successively with biological filter;
On pipeline between common blodisc and biological filter, be connected with nitrification liquid reflux line;
The other end of nitrification liquid reflux line is connected on the pipeline between water-in and primary sedimentation pond;
One end of biological filter is connected with water outlet, centre and is provided with the packing layer of polypropylene material.
The denitrogenation processing equipment of the utility model design adopts synchronous denitrification dephosphorizing, be by nitration reaction and absorb phosphorus reaction (the two is aerobic reaction) and in two are reacted structures, complete respectively with release phosphorus reaction (the two is anaerobic reaction) with anti-nitration reaction, thereby and there is nitrification liquid reflux and saved the expense that extra interpolation carbon source is brought; In addition, to carry out filtering heavy to processing water to adopt biological filter, and good and the settling tank that need not be special of effluent quality, has saved floor space and construction cost; Do not need aeration aerating at design aspect, saved energy consumption.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the block diagram of system of the present utility model.
Embodiment
As shown in Figure 1, the utility model is made up of water-in, primary sedimentation pond, submerged blodisc, common blodisc, biological filter and water outlet;
Water-in, primary sedimentation pond, submerged blodisc, common blodisc are connected in order from left to right successively with biological filter;
On pipeline between common blodisc and biological filter, be connected with nitrification liquid reflux line; The other end of nitrification liquid reflux line is connected on the pipeline between water-in and primary sedimentation pond; One end of biological filter is connected with water outlet, centre and is provided with the packing layer of polypropylene material.
Filler is polypropylene material, and packing specific area is large, and the place of microorganic adhesion is provided, and a large amount of microorganisms form microbial film at filling surface, and dirty water pollutant is degraded; In addition, between filler, there is space, also have pollutent is carried out to filteration.
The concrete main units adopting of the utility model is respectively primary sedimentation pond, submerged blodisc, common blodisc and biological filter.Submerged blodisc surface-area is large, for Ammonifying bacteria, nitrobacteria, denitrifying bacterium and polyP bacteria provide sufficient place.Common blodisc also helps and forms Jun Zao community, has improved Nitrogen/Phosphorus Removal.Common blodisc, by contacting oxygen supply with air, does not need aeration aerating can complete nitration reaction and absorb phosphorus reaction, has saved the energy; The utilization of submerged blodisc is immersed in water body and reaches anaerobism effect, does not need structures to carry out airtight, has saved construction cost convenient operation.Processing hydromining after denitrogenation dephosphorizing is processed with biological filter, can effectively be filtered out the microbial film of blodisc under coming off, saved second pond, and effluent quality is good.
When the utility model work, first sewage enter primary sedimentation pond, after primary sedimentation pond precipitation, water after treatment enters submerged blodisc, owing to existing anaerobion on submerged blodisc, in this position anaerobion releasing body, phosphorus and denitrifying bacterium carry out denitrification nitrate ion denitrogenation are formed to nitrogen, from water, discharge; Water through the processing of submerged blodisc enters common blodisc, in sewage, BOD is degraded, occurs aerobic nitrification and aerobic absorption phosphorus reaction at these structures, and a small amount of water is back to submerged blodisc, provide nitrate ion to carry out denitrification denitrogenation to denitrifying bacterium; Finally enter biological filter through common blodisc water after treatment, in biological filter, a small amount of BOD thoroughly not degrading and the microbial film coming off are removed, through biological filter, water quality after treatment is good, then discharges.
The denitrogenation processing equipment of the utility model design adopts synchronous denitrification dephosphorizing, be by nitration reaction and absorb phosphorus reaction (the two is aerobic reaction) and in two are reacted structures, complete respectively with release phosphorus reaction (the two is anaerobic reaction) with anti-nitration reaction, thereby and there is nitrification liquid reflux and saved the expense that extra interpolation carbon source is brought; In addition, to carry out filtering heavy to processing water to adopt biological filter, and good and the settling tank that need not be special of effluent quality, has saved floor space and construction cost; Do not need aeration aerating at design aspect, saved energy consumption.
Above-mentioned embodiment is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art make within the scope of the technical solution of the utility model, also all belong to protection domain of the present utility model.
