The present invention relates to a kind of high calcium high-salt sewage denitrogenation carbon source, belong to technical field of sewage.High calcium high-salt sewage denitrogenation carbon source of the present invention, by electron donor component, scale inhibition component, denitrification control component and adjuvant component composition.High calcium high-salt sewage denitrogenation carbon source of the present invention, while effectively reducing total nitrogen in sewage, the hard deposition of calcium is effectively prevented, while adapt to variation water quality, keep the stable operation of sewage disposal system.
Description
Technical field
The present invention relates to a kind of high calcium high-salt sewage denitrogenation carbon source, belong to technical field of sewage.
Background technology
Increasingly harsh with sewage drainage standard, the discharge index of total nitrogen is more and more stricter, national environmental protection department regulation
From 1 day January in 2017, existing sewage-treatment plant performs total nitrogen≤30mg/L discharge standard.For most of sewage disposals
System, using biological nitrification and denitrification technique, i.e., detest that oxygen consumption nitrifies, anaerobic denitrifying effect carries out total nitrogen and gone by microorganism
Remove, total nitrogen can be down to achievement level, this method economical and effective the most.But for the waste water of some high total nitrogens of high salt high calcium,
Especially for chemistry water reuse (treatment water, due to the high salt of water quality, high calcium, difficult Biochemical Characteristics can not enter sewage disposal system with
Other sewage mixed processings, otherwise influence the up to standard and reuse of sewage disposal system.Before the requirement of no total nitrogen discharge index,
This kind of sewage discharges usually as the peace and quiet lower water of hypothesis, and this kind of sewage must individually handle the discharge standard for reaching new now.
By taking chemistry water reuse (treatment water as an example, high salt, high calcium, it is difficult biochemical the characteristics of cause this kind of sewage individually processing be very tired
Difficulty, high salt are unfavorable for the existence of microorganism；High calcium easily causes the fouling of sewage-treatment plant, especially when by anti-nitration reaction
When producing the progress of basicity process, fouling is very serious；The difficult biochemical organic matter caused in sewage is difficult to be utilized that to carry out denitrification anti-
Should.Such sewage is usually intermittent discharge, and salinity is high and fluctuation is big, and big and frequent, treatment effect is impacted to biochemical system
Reply slow.
The denitrification process of biological denitrificaion be microorganism using organic matter carbon source as electron donor, by nitrite, nitrate
Be converted into the process that nitrogen escapes from water, during have basicity generation.Organic matter carbon source kind has a variety of such as starch, grape
Sugar, methanol, ethanol, acetic acid, sodium acetate, the sewage etc. of difficult degradation.These carbon sources are effectively reduced in water in the sewage of routine
Total nitrogen, in high salt high calcium sewage, although the total nitrogen in sewage can also be reduced effectively, but high calcium makes reaction system firmly
The scaling tendency of system increases, and causes sewage-treatment plant sludge MLVSS/MLSS reductions, and sludge activity declines；Stir homogeneous set
It is standby, aerator fouling is serious, cleaning is frequent, laborious time-consuming raising operating cost；Structures inwall bottom of pond is reacted by dirt to be adhered to,
The problem of overhauling difficulty several times increase.
If to carrying out decalcification processing before such biochemical wastewater treatment, the alkaline chemical precipitation device of complete set is needed, will be disappeared
Consume substantial amounts of soda acid while produce reluctant alkaline residue, when bicarbonate alkalinity is low in water, the consumption increase of soda acid amount.It is such
Reusing sewage value is little, and alkaline chemical precipitation economic feasibility is low.Zou little Bing exists《The high COD of high calcium is high, and nitrogen gelatine wastewater is steady in a long-term
Biological denitrificaion experimental study》In, decalcification measure is mentioned to remain on stabilization, and measure promotes calcium to add sodium carbonate into raw water
Hard sedimentation, this method have that operating cost is too high in commercial Application, the big economic irrational shortcoming of the quantity of slag.
CN104711213 discloses a kind of accelerator for being advantageous to salt tolerant nitrobacteria growth in high-salt wastewater, and composition includes：
Sodium chloride, ammonium sulfate, bitter salt, dipotassium hydrogen phosphate, green vitriol, calcium chloride, sodium acid carbonate, nitrous acid
Sodium, vitamin liquid, trace element solution, bacterium solution.The invention is advantageous to improve the salt tolerance of nitrifier in high-salt wastewater, to de-
Except ammonia nitrogen effect is obvious, but the effect without denitrifying carbon source and exist raw water calcium it is firmly high when denitrification process easily generation is heavy
The shortcomings that shallow lake.
CN102583706 discloses a kind of high salt, low-carbon industrial waste water continuous bio-synergistic removes the processing method of ammonia nitrogen,
The invention, which is related to aeration tank water inlet end, persistently adds the next constantly improve nitrification effect of the nutrient solution containing microorganism.Nutrient solution bag
Biological inoculum, the nutrient solution needed for activation biological inoculum, carrier, dechlorination running water are included, nutrient solution is mainly used in the activation of strain.
The invention also without denitrifying carbon source effect and equally exist calcium it is firmly high when easily generation precipitation the shortcomings that.
In summary, in current high calcium high-salt sewage removing total nitrogen system operation, following technical problem be present：
1st, the carbon source of pure component can only provide electron donor, it is impossible to take into account the stable operation of system.
2nd, after high salinity has inhibitory action, system to be hit microorganism, treatment effect recovers slow.
3rd, basicity caused by denitrification process promotes calcium to precipitate firmly, is mixed in sludge, causes sludge settling too fast and heavy
Accumulate in bottom of pond, cause treatment effect to decline, stirring expense rise.
4th, basicity caused by denitrification process promotes calcium to precipitate firmly, and installations and facilities cleaning repair rate is high, influences normally to transport
OK.When operation, maintenance cost are too high, sewage disposal system will be forced to shutdown.
If the 5, carrying out decalcification pretreatment to sewage, consume a large amount of soda acids and produce a large amount of alkaline residues.
The content of the invention
It is an object of the invention to provide a kind of high calcium high-salt sewage denitrogenation carbon source, it effectively reduces the same of total nitrogen in sewage
When, the hard deposition of calcium is effectively prevented, while variation water quality is adapted to, keep the stable operation of sewage disposal system.
