Description
Technical field
The present invention relates to biological wastewater treatment and reuse field, more particularly to a kind of enhancing anaerobism while denitrification methane phase
The method of granule sludge stability.
Background technology
Current water environment pollution situation shows new trend with the quickening of industrialization and urbanization paces, in water body
Organic pollution component is increasingly sophisticated, Recalcitrant chemicals ratio is substantially improved, and the nutrition content such as nitrogen phosphate and sulfur increases, single
The efficient control of water environment pollution relatively difficult to achieve of one treatment technology is with administering.Anaerobism while denitrification methane phase coupling processing skill
Methane phase is realized and coupled by art with denitrification metabolism in same reactor, is promoted biological chain cometabolism between flora, is effectively carried
Hydrolysis acidification efficiency is risen, the intermediate product such as propionic acid, butyric acid and basicity is generated during preferential degradation under the collaboration of denitrification flora
Stability in enhancing system, realize anaerobic bio-treated functions expanding and improved efficiency；Denitrification flora is more during
Sample carbon source, realize that carbon source is augmented, effective lifting process stability, realize " 1+1>2 " effects.The anaerobic waste water first of denitrification production simultaneously
Alkane coupling processing technology, also can be less anti-while conventional anaerobic biological treatment and biological denitrification process defect is made up
Answer and the materials such as Organic carbon and nitrogen element and phosphorus, sulphur are realized in device with removing, flow is compact, occupation of land is few, has carbon source supplement concurrently and energy returns
The advantages that receipts, many advantages such as resource and energy resource consumption can be effectively reduced, be applied to a variety of high concentration carbons, nitrogen wastewater treatment
In, significant effect.
However, in coupling process because in Granular sludge the fast breeding of different microorganisms flora and succession cause its thing
Change characteristic and space structure and significant changes occur, show as particle diameter increase, loosely organized, density diminishes easy floating, inside have compared with
Macroscopic-void, and its thalline secretes a large amount of extracellular polymerics, the increase of granule sludge outer surface stickiness, is more easy to bubbles attached so that body
Granule sludge easily floats out reactor in system, cause processing system biomass be lost in, to a certain extent influence treatment effect and
Process stability.Use for reference during the complete denitrification denitrogenation of upwelling type, missed a chance rate to reduce its floating flow, employ reduction
Granularity (agitator cutting), increase grain density (iron filings mixing) and the bubble adhesion power that weakens (activated carbon throwing
Add), the above method reduces loss probability interior in short-term, but can not avoid granule sludge floating to be lost in completely.There is research
The multiplication rate of the multiplication rate, especially denitrification flora of microorganism in reduction system is shown, can be effectively in reduction system
Granular sludge is lost in probability, and it substitutes (metabolic rate is slower) and protonitrate nitrogen by using reduction operation temperature, carbon source
The methods of load, deploys correlative study, and relatively stable granule sludge (Feng is obtained under relatively low nitrate nitrogen load
Wang,Xibiao Jin,et al.A control strategy for promoting the stability of
denitrifying granular sludge in upflow sludge blankets,Environmental
Technology,2014,35(1-4):52-59,DOI:10.1080/09593330.2013.808250)。
In above-mentioned published technical method, by stirring physics cutting, mixed with iron filings and activated carbon adds etc. singly
Pure physical means are transformed the characteristic such as granularity, density in system, and reducing it, to be lost in probability limited, and by particle
Sludge mixes with iron filings, can only increase sludge proportion in certain time after adding, subsequently cause to imitate with iron ion dissolution
Fruit is had a greatly reduced quality；And the methods of by reducing operation temperature, carbon source replacement and reducing nitrate nitrogen load, manual control system
Middle denitrification bacterial metabolism and multiplication rate, avoid granule sludge excessively increase and physicochemical characteristic mutation, can effectively realize particle
Sludge strengthens and retention.But its infringement of metabolism and multiplication rate simultaneously to system treatment effeciency is larger in reduction, and carbon source
Replacement also adds processing cost to a certain extent；In addition, denitrification methane phase granule sludge is compared to complete anti-nitre simultaneously
Change granule sludge, flora is formed increasingly complex during it.
How system to be handled while different flora multiplication rates in regulating and controlling anaerobism while denitrification methane phase system
Efficiency is not caused compared with macrolesion, finds novel reinforced while denitrification methane phase granule sludge stability method, in the future more
Realize that the development and application of efficient waste water coupling processing technology is significant well.
