2, because the interior biosolids amount of biological contact oxidation pond is many, current mix fully, so the cataclysm of water quality and quantity is had stronger adaptive faculty;
3, surplus sludge volume is few, does not have the sludge bulking problem, and operational management is easy.
4. purification efficiency height; The processing required time is short; Change adaptability to the water inlet organic loading is stronger; Needn't carry out mud and reflux, not have the sludge bulking problem simultaneously.
Biological contact oxidation process has the basic characteristics of biomembrance process, but is not quite similar with general biomembrance process.The one, all be immersed in the waste water for the microorganism attached filler of dwelling, so biological contact oxidation pond claims the submerged filter tank again.The 2nd, adopt mechanical means oxygenation in waste water, and be different from general biological filter by the natural ventilation oxygen supply, be equivalent in the aeration tank, add for the microorganism attached filler of dwelling, also can be described as aeration circular form filter tank or contact aerator.The 3rd, also there is about 2～5% suspended state active sludge in the pond in the waste water, to waste water also aseptic.Therefore biological contact oxidation process is a kind of biomembrance process with activated sludge process characteristics, has the advantage of biomembrance process and activated sludge process concurrently.
The bio-contact oxidation system can make the organism in the waste water well be decomposed at present, the effect of removing COD is obvious, but owing in the traditional biological catalytic oxidation system aerating system is arranged all, though there is certain anaerobic environment in the microbial film inside that forms in filler, can carry out denitrification process, but because whole system is because the effect of aeration, so belong to aerobic environment generally, aerobic microbiological is occupied an leading position in this environment, decomposing organic matter is preferably arranged, promptly reduce the effect of COD, but under this aerobic environment denitrifying bacteria effect less, cause the denitrification effect of biological contact oxidation pond with this understanding undesirable.
The utility model content
The utility model is at the prior art above shortcomings, a kind of strengthened denitrification biological contact oxidation pond is provided, be provided with by certain spatial array and arrangement, can make current pass through filtering membrane and combined stuffing successively and the thorough mixing effect, utilize in the sewage existing nutritive substance or the extra carbon source material that adds is grown and carry out denitrification denitrogenation the metabolism decomposing organic pollutant time along the cloth stream line of setting.This device elementary biological contact oxidation pond can be handled and nitrated after sewage in the anti-back formation nitrogen that digests of nitric nitrogen remove, thereby in bio-contact oxidation, strengthened the denitrification effect of whole system to sewage.
The utility model is achieved through the following technical solutions, and the utility model comprises: water inlet pipe, rising pipe, pond body and filter mechanism, and wherein: water inlet pipe and rising pipe are arranged at the two ends of pond body respectively, and some groups of filter mechanisms are crisscross arranged in the Yu Chiti successively.
Described filter mechanism comprises: filler rack, filler, support and filtering membrane, and wherein: filtering membrane is fixedly set in the support, and support is fixedly set in a side of filler rack, and filler is fixedly set in the filler rack.
Described positive and negative staggered being meant: two adjacent filter mechanisms be crisscross arranged respectively bottom and top with the pond body.
This device workflow is as follows:
Open water inlet pipe, pending waste water is incorporated in this biological contact oxidation pond, then current flow according to body the place ahead, direction pond of differential water pressures, after having run into the first layer filtering membrane, because current are bigger by the resistance of film, it can be through continuing to flow forward through space, film below, and then the 3-D filler layer at process film rear, after the thorough mixing effect, flow to second layer filtering membrane again, be subjected to upwards flowing behind certain resistance and through second 3-D filler layer, continuing to be docile and obedient preface after the thorough mixing effect again flows forward, membrane module in the total system and 3-D filler assembly are arranged and series arrangement through certain spatial distribution, can make sewage in the process of whole system of flowing through, water body fully contacts successively mutually with membrane module and filler, attached to the microorganism and the effect of pollutants in sewage matter thorough mixing that reach on the film in the 3-D filler, has reached the effect of good removal pollutent; Be no aerating apparatus in addition in this system, this system is in little oxygen or little anaerobic state behind the stabilizing treatment certain hour, aerobic microbiological accounts for less part under this state, this part aerobic microbiological can be eliminated COD residual in the sewage, and the ratio of anaerobion rises in this state, denitrifying bacteria increases gradually, effect strengthens, it can carry out denitrification with the nitric nitrogen of leaving in the previous processed process, thereby make nitrogen well be removed effect, be connected with a water shoot on the top of pond body end, can or enter next step with the water qualified discharge handled and further deeply handle.
What need be noted is: before this new bio catalytic oxidation system handles, the comparatively ideal state of water body is that wherein nitrogen mostly is nitric nitrogen greatly, be convenient to the carrying out of this denitrification step like this, so before this new bio catalytic oxidation system, suggestion connects an elementary bio-contact oxidation system, in this system, carry out processes such as aeration oxygen replenishing, make it in the process of carrying out aerobic sigestion, make the nitrogen in the water body become nitric nitrogen, so that the better effectiveness of this novel reinforced denitrogenation bio-contact oxidation system's performance.
Under a lot of situations, enter the waste water of this new bio catalytic oxidation system owing to passed through the many treating processess in front, COD value wherein is very low, this shows that the carbon source material that wherein supplies microorganism growth and energy requirement may be not enough, and the deficiency of carbon source material will directly influence the size and the denitrifying action effect thereof of biomass in this system, so COD cross low or the insufficient situation of carbon source under, perhaps at initial stage that microorganism colonization is cultivated, the carbon source add-on system can be set at the front end of system, take the circumstances into consideration to add corresponding carbon source material for example glucose or methyl alcohol etc. according to practical situation, for microbial growth and metabolism provide energy, thereby be more conducive to the carrying out of denitrification process, so that whole system reaches best effect.
In this device, owing to do not use aerating system, thereby the current in the total system stir and mixture strength is littler than using aerating system, so on the film and the amount of coming off of microbial film in the filler and active sludge less, this makes the water outlet SS of total system lower, thereby can improve effluent quality, but increase along with the reaction times, microbial film in microbial film and the filler and mud are changed speed and are thickeied more slowly and gradually, may stop up easily than aeration and biological catalytic oxidation cell system, so this new bio catalytic oxidation cell system is in operational process, at set intervals or treatment effect when not good, will regularly carry out the pond body, the cleaning of membrane module and 3-D filler assembly is cleared up and is dredged, thus the normal operation of the system of assurance.
