Abstract
A kind of device and method that realizing municipal sewage integral anaerobic ammoxidation autotrophic denitrification is related to technical field of biological sewage treatment.Device is equipped with city domestic sewage raw water water tank, biology except carbon dephosphorizing reactor, intermediate water tank and integrated autotrophic denitrification upflow-type reactor.Two kinds of bacterium: the ammonia oxidation bacteria of wadding body form and the anaerobic ammonia oxidizing bacteria being attached on filler are primarily present in integrated autotrophic denitrification upflow-type reactor.Municipal sewage initially enters biology except carbon dephosphorizing reactor, carries out anaerobism during water inlet and puts phosphorus；It is aerated after water inlet end, removal Organic substance in water is acted on by activated sludge absorption, while carrying out aerobic phosphorus absorption.Then sewage continuously enters integrated autotrophic denitrification upflow-type reactor through intermediate water tank, by intermittent aerating, realizes short distance nitration-anaerobic ammoxidation.The present invention separates flora without adding outer carbon source, guarantees that the efficiency of system dephosphorization denitrogenation, energy saving are with the obvious advantage.
Description
Technical field
The present invention relates to technical field of biological sewage treatment more particularly to a kind of realization municipal sewage integral anaerobic ammonia oxygen
Change the system and method for autotrophic denitrification.
Background technique
Nitrogen content is the important indicator of Water-quality control.The aggravation of nitrate pollution is also to cause China lake, river in recent years
One of an important factor for waters wawter bloom such as stream and coastal waters and red tide large-scale outbreak, therefore cause the extensive concern of people.
The ammonia nitrogen removal of conventional waste water processing realizes generally by nitrification and denitrification process, but this process need a large amount of aerations,
Organic carbon source and basicity are additionally added, investment and operating cost are high, but also can generate secondary pollution.Anammox denitrogenation
It is a kind of new and effective bio-denitrification technology to grow up the nineties in last century.The anaerobism ammonia compared with traditional biological denitrogenation technology
Oxidation reaction approach is shorter, it is not necessary to which basicity compensates and adds organic carbon source, to save a large amount of energy and material, saves
The problems such as operating cost, the low ratio of carbon to ammonium denitrogenation of waste water faced to the current sewage treatment interface in China is difficult, energy consumption is high, sludge yield is big
Bring dawn.Therefore, the extensive research of domestic and foreign scholars has been attracted.
Anammox refers to that under anaerobism or anoxia condition, microorganism is directly with NO2 -For electron acceptor, with NH4 +For electricity
Sub- donor, converts two kinds of nitrogens to the bioprocesses of nitrogen simultaneously, and the energy that this process generates can make anaerobism ammonia oxygen
Change bacterium to survive under anaerobic.Anammox technology is the most economical bio-denitrification technology being currently known, and traditional
Nitration denitrification technology is compared, and has many advantages, such as that oxygen demand is low, and operating cost is low and does not need additional carbon.
Anammox technology is to be currently known most economical bio-denitrification technology, this is because its technical characterstic is determined
Fixed.Reason is: 1. in anaerobic ammonium oxidation process, since anaerobic ammonia oxidizing bacteria is autotrophic bacterium, CO2Or carbonate is its life
Long required inorganic carbon source, so NH4 +The oxidation of-N is not necessarily to O2It participates in, while NO2 -Without organic carbon source, this will for the reduction of-N
A large amount of operating costs for reducing sewage aerobic biological denitrificaion；2. the growth rate (doubling time 11d) of anaerobic ammonia oxidation microbiological
With yield (0.11g [VSS]/g [NH4 +]) be low-down, therefore sludge yield is low, however the conversion ratio of nitrogen be but 0.25mg [N]/
(mg [SS] d), it is suitable with traditional aerobic nitrification.
But Anammox technology also fails to be used widely in engineering practice at present, main reason is that: 1. detest
Sewage used by anaerobic ammonium oxidation technology experiment is studied is mostly artificial distribution, and there are biggish differences with the water quality of actual sewage
Away from；2. being easy to be lost in Anammox reaction initial operating stage sludge, keep enrichment anaerobic ammonia oxidizing bacteria and stable operation more tired
It is difficult.
Thus, a technical problem for needing to solve at this stage is: how to propose a kind of effective measures, passes through one
Body Anammox autotrophic denitrification Process for Treating Municipal, enables Anammox technology to be successfully applied in actual city
In city's sanitary sewage, and Anammox reaction initial operating stage can more enrichment anaerobic ammonia oxidizing bacteria and stable operation it is anti-
Device is answered, sludge is not easily runed off.
