Description
Technical field
The present invention relates to a kind of to treatment of advanced stage landfill leachate autotrophy advanced nitrogen biological treatment device and method, belong to low ratio of carbon to ammonium ammonia nitrogen in high density treatment of advanced stage landfill leachate bio-denitrification technology field, be applicable to the biological denitrificaion of the low C/N such as treatment of advanced stage landfill leachate than high ammonia-nitrogen wastewater.
Background technology
In recent years, along with the continuous increase of municipal solid waste output, landfill method becomes most widely used treatment and disposal method in the world gradually.If the percolate that landfill produces is not adopted an effective measure controlled, then can severe contamination surface water or underground water.Percolate because of have complicated component, water quality and quantity change greatly, the water quality characteristics such as organism and ammonia nitrogen concentration is high, the imbalance of microbial nutrition element ratio, make it be treated as one of still unsolved difficult problem in international coverage.The famine of organic carbon source is the barrier that mature leachate nitric efficiency cannot improve, and additional organic carbon source significantly can increase the expense of sewage water denitrification.Therefore, the apparatus and method proposing more efficiently denitrogenation are needed.Traditional wastewater biological denitrificaion is by nitrated by NH
4 +-N is converted into N0
3 --N, then by denitrification by N0
3 --N is converted into nitrogen and overflows from water.The denitrification stage is with N0
3 --N is electron acceptor(EA), and mineralized nitrogen, as electron donor, is that nitrogen completes biological denitrificaion by organism.But for the treatment of advanced stage landfill leachate denitrogenation of the low organic concentration of high ammonia nitrogen, its C/N, than often lower than 4, due to organic carbon source wretched insufficiency, causes traditional biological nitric efficiency to reach about 10%.
Receive much concern since Anammox phenomenon self-discovery.In anaerobic ammonium oxidation process, ammonia nitrogen and nitrite nitrogen can be converted into nitrogen by anaerobic ammonia oxidizing bacteria, and do not need the participation of oxygen, and whole process belongs to autotrophy process completely.Therefore compared with traditional nitration denitrification, short distance nitration-anaerobic ammoxidation technique can save the oxygen supply expense of 60%, and without the need to additional carbon, greatly reduce processing costs and the capital cost of sewage disposal.As a kind of bio-denitrification technology of Sustainable development, anaerobic ammonia oxidation process has good prospect.But anaerobic ammonia oxidizing bacteria belongs to autotrophic bacteria doubling time (11d) length and productive rate (0.11g [VSS]/g [NH
4 +]) low, be not easy enrichment at short notice.Simultaneous reactions device initial stage mud easily runs off, and causes the smooth enrichment of anaerobic ammonia oxidizing bacteria more difficult.
Which kind of mode the reactor that different scholar's research is different explores is applicable to anaerobic ammonia oxidizing bacteria (anammox) growth.Such as fluidized-bed reactor, biofilm reactor, upflow anaerobic sludge blanket reactor (UASB) and sequencing batch activated sludge reactor (SBR) reactor.In all reactors studied, sequencing batch activated sludge reactor (SBR) cuts the strong characteristic of good fluidity controllability and is considered to be best suited for the reactor that anaerobic ammonia oxidizing bacteria (anammox) grows because it is biological.The time that anaerobic ammonia oxidizing bacteria (anammox) doubles required in sequencing batch activated sludge reactor (SBR) is than shortening one times in a continuous flow reactor.
The severe reaction conditions of Anammox (requires NH in water inlet
4 +-N:NO
2 --N=1:1.32), if NH in water inlet
4 +-N and NO
2 --N does not reach the residue that proportion requirement then still has a nitrogen element after Anammox reaction to be difficult to reach effluent quality requirement.For short distance nitration coupling Anammox two stage process, how to control the reaction conditions of short distance nitration, the reaction making water outlet meet follow-up Anammox requires to become short distance nitration coupling Anammox two stage process a great problem.Not only there is ammonia oxidation bacteria but also there is anaerobic ammonia oxidizing bacteria, at aeration phase ammonia oxidation bacteria by part NH in integration autotrophic denitrification sbr reactor device
4 +-N is converted into NO
2 --N, utilizes remaining NH at agitation phases anaerobic ammonia oxidizing bacteria
4 +the NO that the short distance nitration stage generates by-N
2 --N is converted into N
2with a small amount of NO
3 --N.Integration autotrophic denitrification reactive system takes the mode of circular gap aeration, often will remove part nitrogen until nitrogen is removed completely in reactor, concise in technology through an aeration/stirring, easy to operate, high efficiency.
The research and apply of current integrated autotrophic denitrification technology mainly concentrates on the trade effluent of mud nitrification liquid and high ammonia nitrogen, and for complicated component, water quality and quantity change greatly, the treatment of advanced stage landfill leachate of ammonia nitrogen concentration high and microbial nutrition element ratio imbalance reports less.
