Description

A kind of method utilizing anaerobic filter to start Anammox fast
Technical field
The present invention relates to a kind of method utilizing anaerobic filter to start Anammox fast, belong to technical field of sewage.
Background technology
Anammox (anaerobicammoniumoxidation, ANAMMOX) technique is a kind of Process of Biological Nitrogen Removal, be be electron donor with ammonia, take nitrite as the biological respinse of electron acceptor(EA), reaction product is nitrogen, has a good application prospect in wastewater biological denitrificaion field.Anammox, compared with traditional nitration denitrification, is a kind of more efficient and denitrogenation mode of economy, can not only saves the organic carbon source of more than 50% energy and 100%, can also reduce the discharge of greenhouse gases.It because of have oxygen-consumption few, without the need to additional carbon, sludge yield numerous nothing and the advantage of analogy such as low and non-secondary pollution, cause the great interest of domestic and international researcher.
At present, the denitrogenation of waste water technology about Anammox has achieved certain achievement in research and has put into practice knowhow, but how to start the bottleneck problem that this reaction is still the application of this technology of restriction fast.The start-up course of anaerobic ammonia oxidation bioreactor, is essentially activation and the amplification procedure of microorganism in reactor, and the key that reactor successfully starts makes microbe population reach design requirements as early as possible.For poky microorganism, the main policies improving biomass in reactor reduces biological loss, usually adopts two kinds of methods: cultivate microbial film, make microorganism be fixed in microbial film; Cultivate granule sludge, and create good settling condition, organism is retained in reactor.
But, because most Anammox Pseudomonas is strict autophyting growth bacterium, grow extremely slow, doubling time reaches 11d, and just there is activity when only having high cell concentration, simultaneously more responsive to external environment factors such as oxygen molecules, cause enriching floras to be cultivated more difficult, anaerobic ammonia oxidation reactor is difficult to quick startup.
