Description
Technical field
The utility model relates to urban sewage treatment technology field, particularly relate to a kind of regeneration of urban sewage treatment unit, this device comprises high loading organics removal reactor, short distance nitration-anaerobic ammoxidation denitrification reactor and ozone oxidation reaction device, realized oxygenation and the mixing requirement of different reactor by air separation, can be applicable to municipal sewage treatment, technical process is simple, red-tape operati is flexible, and effluent quality is high.
Background technology
The most general technique of municipal sewage treatment is activated sludge process.Traditional activated sludge process, by active sludge alternate run under the environment of anaerobic-aerobic, can realize multiple pollutant simultaneously and remove.In aerobic environment, microorganism carries out nitration reaction and utilizes organism to carry out anti-nitration reaction under removing partial organic substances, anoxia condition realizing denitrogenation.The denitrification effect of conventional nitration denitrification process affects significantly by organic, and under low ratio of carbon to ammonium condition, nitric efficiency is general not high.The municipal effluent carbon-nitrogen ratio of China is generally on the low side, and the organism in water inlet fails efficiency utilization, causes water outlet nitrogen element to be difficult to stably reaching standard, does not meet the basic demand of reclaimed water reuse.
Anaerobic ammonia oxidation process appear as municipal sewage treatment and regeneration provides new thinking.Ammonia nitrogen and nitrite directly can be converted to nitrogen by anaerobic ammonia oxidation process.And anaerobic ammonia oxidizing bacteria is chemosynthetic autotroph, be electron donor without the need for machine carbon source in denitrification process, the corresponding minimizing of sludge yield.Denitrification process based on Anammox technology can save aeration energy consumption compared to the nitration denitrification technique of routine, does not need extra organism as carbon source, has advantage significantly.What anaerobic ammonia oxidation process realized that carbon removes with nitrogen pollutant is separated, and changes sewage treatment process.
Technical process based on Anammox technology it is also proposed new requirement to aeration mode.The appropriate design of aerating system and steady running are the essential condition that activated sludge process realizes pollutant removal.Aeration can provide oxygen for the microorganism of active sludge, in order to oxidation of organic compounds and ammonia nitrogen; In addition, aeration can realize good gas-liquid-solid three-phase mixing, and reinforcing mass transfer, improves contaminant removal efficiency.In traditional activated sludge process, oxygen mass transfer efficiency is generally limited, and therefore general passing through increases aeration rate and improve the oxygen supply that oxygen-transfer efficiency realizes abundance, and under this condition, the mixture strength of system does not belong to restricted condition.Therefore conventional aeration mode can realize good oxygenation and mixing effect simultaneously, the effective pollutent removed in sewage.Based on the urban sewage treatment process flow process of Anammox technology, the reactive system bearing organic matter removal needs enough dissolved oxygens, and aeration rate increases.Organic removal reactor carries out pure oxygen aeration, can improve reaction efficiency, reduces aeration energy consumption.And short distance nitration-anaerobic ammoxidation reactor mainly realizes the removal process of polluted by nitrogen, oxygen requirement significantly reduces, under whole system needs to maintain low DO condition.Traditional aeration mode is adopted to be difficult to meet denitrogenation requirement.Under higher aeration rate, although good oxidation effect can be realized, uncontrollable rational dissolved oxygen concentration.When after reduction aeration rate, under low DO condition, the mixed effect of system weakens, and causes the elimination capacity of system to reduce.For Anammox technology Problems existing in sewage disposal application, should consider how to optimize aeration mode, for the removal of organism and nitrogen pollutant provides rational aeration rate and mixture strength, and further optimize its control strategy, by the synthetic operation with advanced treatment system, realize the reuse water water outlet requirement of high-quality.Therefore, study a kind of regeneration of urban sewage treatment unit and there is important Research Significance.
