sbe converted into poly-β hydroxybutyric acid PHB, polyP bacteria and Denitrifying Phosphate Accumulating Organisms are bred rapidly, become the dominant microflora of composite purification device, be conducive to the simultaneous nitrogen and phosphorus removal at degraded BOD.
Solid 3, the biochemical reaction of sewage purification be gas-water-phase reaction, reactant is delivered to reaction interface by mass transfer as organism, oxygen, and resultant of reaction also will transfer out through mass transfer; Mass transfer velocity often becomes the bottleneck of conditioned response process, and the utilization of central tube fluidization technology makes central tube flow velocity reach 50mm/s, has improved rate of mass transfer, and biochemical reaction speed is significantly improved.The strengthening of web plate to hydraulic shear, makes microbial film and granule sludge keep very high biological activity, and everything has all improved the task performance of cleaner.
4, adding of web plate, breeds and forms microbial film and created condition for microorganism adheres on web plate, generally, reactor operation 3～5d, microorganism can biofilm and form microbial film; In microbial film, due to only 100～150 μ m of depth of penetration of oxygen, and the avidity of ammonia oxidation bacteria AOB and oxygen is far above NOB NOB, this has just created condition for nitrosification in microbial film and has facilitated short-cut nitrification and denitrification, test shows, the activity that suppresses NOB NOB is the key of short distance nitration steady running, except DO, free ammonia FA concentration (0.6～5mg/l) the nitrous acid FNA(0.02 mg/l that dissociates) and low water temperature (<15 DEG C) condition all can make NOB be suppressed
Biochemical practice reaction proves: microorganism hungry-be satiated with food is not only conducive to stablizing of granule sludge under the operating mode of complex Alternating, and can bring into play to greatest extent its purification efficiency.At the bottom of pond and the decline cyclone ring top creation of forms of intaking respectively microorganism hunger---the environment of the reciprocation cycle of being satiated with food, not only improved purification efficiency, also can reduce excess sludge discharge amount.Because the mud of web plate microbial film and granule sludge is all very long age, longer mud impels microorganism to experience the endogenous respiration course of self bio-oxidation age, and excess sludge is reduced, and has reduced sludge yield from source.
5, in decline cyclone ring, sewage injects Chi Tihou with tangential direction, will drive mixed solution to rotatablely move with the form under screw; Due to rotary centrifugal force with grain diameter size and different, this will facilitate the further coalescence of discrete small-particle, the further densification of granule sludge is not only conducive to dirty water clarification, also helps granule sludge the separation of impurity in water is removed.
Research shows, the motion of decline circulation formation potential barrier is compound with swirling motion, particulate matter in water is concentrated away from Bian Bixiang center automatically, this has just created good hydromeehanics condition for sidewall deposit exhalant region is set, also make water outlet be convenient to precipitate and separate, kept good SS precipitation removal condition.
