In addition to being adjusted to above-mentioned many sampling technologies moreover it is possible to be adjusted to anaerobism, anoxia, aerobe coupling or repeatedly between
Every the Various Complex technique processing.Can corner adjustable type wastewater treatment biochemical reactor arrange in annular gallery 5 movements every
Plate, is sequentially allocated as anoxia section (nitrosation section), anaerobism section (Anammox section) and aerobic section, so composition along water (flow) direction
The new technology of " nitrosation -- Anammox -- Aerobic Process for Treatment ", be primarily adapted for processing ammonia nitrogen is high and the low waste water of carbon-nitrogen ratio.Its
Middle Anammox section is made up of isometric 4 fractions, constitutes the water hole mouth of the mobile dividing plate of Anammox section, successively
It is alternately located in bottom and the top of dividing plate, between two dividing plates, distance controlling is 0.8～1.2 times of annular gallery width simultaneously, makes
Obtain current to carry out；Between two dividing plates of Anammox section, effective water section of crossing arranges filler, is conducive to the shape of Anaerobe film
Become and growth.Anammox section substantially defines the abr reactor of the improvement of filler, Anammox biochemical reaction
Occur in the main abr reactor in improvement.Anaerobic ammonia oxidizing bacteria can be cultivated in the abr reactor of improvement and be bred:
Baffling flowing up and down makes waste water and Anaerobe film contact-enhancing；It is reasonable to detest to obtain that Anammox section is added a cover
Oxygen condition so that in waste water do value lower；Cover the logical upper exhaustor of punching, be the biogas in order to exclude generation in time；Setting is filled out
Material, can extend the time of staying of anaerobic sludge, be conducive to the growth of Anaerobe.
The ratio of the nitrosation section of short distance, Anammox section and the annular gallery angle shared by aerobic section is 1:2:3 or 1:
2:4；Short distance nitration section arranges micro- aerator, controls dissolved oxygen in 0.5～1.5mg/l, Anammox section is anaerobic state,
Control dissolved oxygen to be less than 1.0mg/l, aerobic section arranges aerator, control dissolved oxygen to be more than 2.0mg/l.Short distance nitration section is main
Control and in waste water, generate nitrite nitrogen, and the nitrite nitrogen generating enters Anammox section, can carry out Anammox
Under microbial action, reacting with ammonia nitrogen in anaerobic condition, generating nitrogen, thus realizing denitrogenation.If add in reactor and
Culture is that the anaerobic ammonia oxidizing bacteria of whole process autotrophic then defines " Anammox canon technique ".If in short distance nitrosation
Section adds and cultivate is nitrosation strain, Anammox section add and cultivate be autotrophy anaerobic ammonia oxidizing bacteria, then
Define " Anammox oland technique ".Whole strict control do concentration, controls and for nitrifying process to rest on nitrosation rank
Section, completes half nh in waste water4 +- n changes into no2 -- n, more separately remaining nh4 +- n and no2 -- n reacts, and carry out is anaerobism ammonia
Oxidation reaction is such that it is able to realize high efficiency denitrogenation.It is suitable to process the relatively low high-nitrogen waste water of c/n.
The setting of polylith dividing plate and regulation, can form " Anammox canon+ is aerobic " or " Anammox oland work
Skill+aerobic " new technology, it is possible to resolve traditional a/a/o technique can not process the problem of the relatively low high-nitrogen waste water of c/n well.Anaerobism
Ammonia oxidation process is also the later Main Trends of The Development in denitrogenation dephosphorizing, and the present invention can combine Anammox well, becomes
There is the abr anaerobism workshop section of the improvement of filler.A/a/o technique can be overcome cannot to form Anammox workshop section or Anammox
The problem that effect is very faint, the advantage of being difficult to occupies anaerobic processes, achieves the unforeseeable technique effect of integrated artistic.
Mobile dividing plate is realized along the movement on gallery direction by railroad, and biochemical reactor annular center is provided with
Actuating device is connected with the mobile dividing plate equipped with slide rail rotating pivoted arm, pivoted arm, to realize distribution and the adjustment of each segment volumes.
Against water (flow) direction, adjust the mobile dividing plate of isolation aerobic section first, then dividing plate is fixed；Dismantle the company of pivoted arm and dividing plate
Connect, pivoted arm is connected with another piece of mobile dividing plate, another piece of mobile dividing plate is adjusted, fixes, so just can achieve a pivoted arm
Regulation to the mobile dividing plate of polylith, adjusting means configuration is reasonable, easy to adjust, efficiency high.
Beneficial effect: the present invention provide corner adjustable type wastewater treatment biochemical reactor compared to the prior art have with
Lower advantage:
1st, the corner adjustable type wastewater treatment biochemical reactor that the present invention provides, compact conformation is reasonable in design, can be according to treating
Each section of relative retention time of water quality treatment situation flexible, to carry out flexible isolation to each section using dividing plate so as in
Microbial population is relatively independent, and the environment of corresponding biochemical reaction is more steady.Thus, the biochemical reactor that the present invention provides exists
