Description
Technical field
The present invention relates to water treatment facilities, particularly relate to a kind of anoxic denitrification organisms filter and using method thereof.
Background technology
In intensive culture pond, nitrate content can be made to rise because of fish food and the nitrogen addition being excreted in water
Height, be drained ammonia in the biofilter of recirculating aquaculture system field or organic nitrogen to be oxidized to toxicity less
Nitrate, nitrate will not be filtered out by aerobic filter device but accumulate in water, beyond certain level meeting
It is formed with pest.Traditional mode is to reduce nitrate content in the way of renewing water, and this method is not only
Costliness, and the waste water discharged has high nitrate content, and this may result in river and lake eutrophication.
In closed circulation and from exchanged water treatment technology, using anoxic denitrogenation technology is one of effective means,
During anoxic denitrogenation, nitrate is progressively to be removed in several steps by anoxic bacterium, is finally decomposed to
Nitrogen escapes in air.Some intermediate products are poisonous (such as nitrite), and these noxious materials may
Gather in the reactor, if this process stops the most in due course, when all of nitrate is too much,
Anaerobic bacteria may start to reduce sulfate to form hydrogen sulfide.
Anoxic denitrogenation filter is seldom used in breeding water body circulation, and its reason is that the water capacity processed easily will not contain
Oxygen and containing nitrite by direct blowback culturing pool, this may cause the nitrous acid that high concentration is poisonous
Salt is formed or generates other poisonous or bad smell gases (such as hydrogen sulfide) etc., and the fish of cultivation are caused wound
Evil.

Hopper 61 lower end is provided with a mud control valve 63, and mud control valve 62 is used for unloading precipitating sludge.
The using method of anoxic denitrification organisms filter of the present invention is as follows: anoxic bioreactor 1 is anoxic
Environment, after cultivation water enters into anoxic bioreactor 1, is detected anoxic by an ORP controller 31 raw
The ORP value of cultivation water in thing reactor 1, if ORP value is less than-350mv, the groove 4 that feeds intake is by meter
Organic food thrown in anoxic bioreactor 1 by amount pump 41, and facultative anaerobic bacteria obtains energy by food
Nitrate in water is decomposed into nitrogen, is transferred to oxygenation bioreactor 2 with the water after after-purification, second
The ORP value of water, oxygenation bioreactor 2 in oxygenation bioreactor 2 monitored in real time by ORP controller 32
In by oxygen delivery equipment 5 to its delivered inside oxygen, to ensure containing enough oxygen in water body, through oxygenation
After the purification of bioreactor 2, water is transferred to filter 6, is discharged by outlet pipe 62 after precipitation,
Completing cleaning procedure, treated water body returns to aquaculture pond, or the pond water used after being
Change, redirect in pond, it can be as irrigation water or enter in river.
In the present invention, pentavalent N (V) during facultative anaerobic bacteria utilizes NO3-N and NO2-N and trivalent N (III)
As the electron acceptor in energetic supersession, the course of reaction of electron acceptor constantly will result in nitrate and nitrous
Hydrochlorate is converted into nitrogen, so that ORP value is adjusted so that the ORP value control of anoxic bioreactor 1
System is between-350 to-50mv, and oxidation-reduction potential in the reactor is relevant with oxygen content, if
Oxygen is depleted, and oxidation-reduction potential reduces, if ORP value is less than this, oxygen free condition can make other
The Bacteria Culture of kind, such as Thiobacillus, water quality can be caused new damage with sulfur oxide hydrochlorate by it, another
Aspect, if oxidation-reduction potential rises above-50mv, nitrate reduction has imperfect and high concentration
The nitrite of poison can be accumulated in system, it is impossible to reaches clean-up effect.Therefore, this system ORP value should control
Between-350 to-50mv.
The present invention, by using the anoxic bioreactor water body to purifying to carry out anaerobic digestion decomposition, utilizes and increases
Oxygen bioreactor carries out aerobic breakdown, controls two reactors respectively by ORP controller simultaneously
ORP value, controls ORP value between-350 to-50mv, not only eliminates the nitrite in water, nitre
The harmful substances such as hydrochlorate, the most also effectively prevent other poisonous or bad smell gases of generation, such as hydrogen sulfide
Deng, substantially increase the efficiency of water treatment, it is ensured that clean-up effect.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilization
Equivalent structure or equivalence flow process that description of the invention content is made convert, or are directly or indirectly used in other
Relevant technical field, is the most in like manner included in the scope of patent protection of the present invention.
