Description
Technical field
The invention belongs to municipal sewage treatment and resource utilization field.Be specifically related to be exclusively used in the method for the high-level efficiency less energy-consumption manipulation of regeneration of municipal effluent under the normal temperature condition.
Background technology
At present, the key that water pollutes is the body eutrophication problem that exceeds standard and cause because of phosphorus nitrogen, therefore, is an urgent demand that newly-built regeneration effluent water factory or existing Sewage Plant all are faced with the sewage deep dephosphorization denitrogenation.For the biological dephosphorize denitrification system,, mainly show as to the different of dissolved oxygen, mud demand in age with to the contention of carbon source because dephosphorization bacterial and denitrifier exist contradiction and competition biologically.When phosphor-removing effect was good, denitrification effect was then relatively poor, and vice versa, and this just makes simple placed in-line dephosphorization denitrogenation system (as oxidation ditch, SBR and A
2Technologies such as O) be difficult to obtain simultaneously satisfied dephosphorization and denitrification effect.
Universally recognized in the world biological phosphate-eliminating theory is that (poly-phosphate accumulating microorganisms is called for short polyP bacteria, anaerobic phosphorus release PAOs)/aerobic suction phosphorus principle to polymer phosphate salt accumulation microorganism.In conjunction with the metabolic rule of dephosphorization bacterial, to open outstanding academician and proposed typical anaerobic/aerobic activated sludge process, it can reach deep phosphorous removal and remove organic purpose under the condition that does not increase investment of traditional activated sludge process Sewage Plant and working cost.This method has obtained application at present in municipal effluent regeneration engineerings such as Dalian, practice shows, the aerobic/anaerobic activated sludge process with traditional activated sludge process relatively has that reactor is little, phosphor-removing effect good, sludge settling property good (can kill thread fungus), does not increase initial cost (can transform slightly) and move advantages such as simple on original technology basis.Therefore, aerobic/anaerobic activated sludge process dephosphorization technique can be regarded as the preferred option of municipal effluent biochemical treatment.
Traditional nitrated/denitrification biological denitrogenation technology self has energy consumption and the high characteristics of material consumption, and the ratio of city domestic sewage C/N is lower at present, it is the carbon source deficiency that biological denitrificaion is handled the greatest problem that is faced, just must additionally add carbon source for reaching satisfied denitrification effect, thereby cause the cost of sewage disposal to increase greatly, this is the bottleneck of restriction sewage disposal and resource utilization.
Short distance nitration/denitrification (shortcut nitrification/denitrification) biological denitrificaion is meant by control reaction conditions (as temperature, dissolved oxygen and HRT etc.), with NH
4 +The nitrated NO that is controlled at of-N
2 -In-N the stage, then carry out denitrification denitrogenation.
Anammox (anaerobic ammonium oxidation is called for short ANAMMOX) is based on unique technology that novel bacterial is set up, and it is meant that under anaerobic, anaerobic ammonia oxidizing bacteria is with NO
2 --N (based on short distance nitration) is an electron acceptor(EA), directly with NH
4 +-N is converted into N
2, in reaction process, do not need organic carbon source can realize autotrophic denitrification, therefore, ANAMMOX is a kind of more promising biological autotrophic denitrification technology.
At present, the old road of developed country is still continued to use in the production of China's reuse water, promptly on the basis of municipal wastewater treatment plant secondary effluent, series combination deep phosphorous removal denitrification process again, caused that existing municipal effluent manipulation of regeneration exists that technical process is long, the unit collocation is unreasonable, problems such as investment and working cost height, cause the cost value of reuse water higher, make reuse water compare the advantage economically that lost with tap water, this is the bottleneck of restriction sewage disposal and resource utilization.Current, the subject matter that the municipal effluent manipulation of regeneration is badly in need of solving is the efficient pollutant removal gordian techniquies of research and development, and set up the municipal effluent regeneration full-flow process of system optimization on this basis, guaranteeing that stable effluent quality reaches under the prerequisite of reclaimed water reuse standard, accomplishes to save energy and reduce the cost.
