Description
Technical field
The utility model relates to sewage treatment area, is specifically related to a kind of bacteria filter device.
Background technology
BAF is developed by trickling filter, and used for reference rapid filter form, completes the function of bio-oxidation and solid-liquid separation in a unitary reactor simultaneously.BAF fully uses for reference the mentality of designing of sewage disposal contact oxidation method and feedwater rapid filter, biological degradation and adsorption filtration two kinds for the treatment of processess is incorporated in same unitary reactor.With the particulate filler loaded in filter tank (as haydite, coke, quartz sand, gac etc.) be carrier, aeration is carried out in inside, filter tank, filter material surface is grown large number of biological film, when effluent stream through time, to utilize on filtrate the living microorganism Strong oxdiative Decomposition of appended microbial film middle and high concentration and the less feature of particle diameter of filter medium, give full play to the biological metabolism of microorganism, biofloculation, the physical adsorption of microbial film and filler and retain and in reactor along the classification predation of water (flow) direction food chain, the high-efficient cleaning realizing pollutent removes, utilize in reactor aerobic simultaneously, the existence of anoxic zones, realize the function of denitrogenation dephosphorizing.But the filler applied in the market arranges complex structure, aerator installation and maintenance difficulty, microbial film is blocked up, easily blocks.
Summary of the invention
The utility model, for above problem, provides the bacteria filter device that a kind of structure is simple, easy to use.
The utility model is achieved through the following technical solutions: a kind of bacteria filter device, is characterized in that: comprise micro-nano bubble generator; Described micro-nano bubble generator is connected to pool and biological filter by pipeline; Be provided with exhaust inner chamber in described pool, the bottom of exhaust inner chamber is provided with pipeline tapping, and the top of pipeline tapping is provided with micro bubble releasing device; The bottom of described pool is provided with water shoot, and water shoot, through exhaust inner chamber, water shoot is evenly distributed with opening, and water shoot one end, through the side of pool, is connected with water distributor; Described water distributor is arranged on the top of biological filter; The inside of described biological filter is provided with filter material layer.
Further, dreg collecting slot is provided with above the side of pool.
As optimization, the height of exhaust inner chamber is no more than 2/3rds of pool height.
The usefulness of this utility model is, original cloth pond is transformed into nanometer air flotation pool by the utility model, also possesses cloth water function simultaneously, transformed aerating system simultaneously, nanometer aeration device makes water mix with gas height to mix, and ultrasonic cavitation disperse discharges highdensity, uniform submicron bubble, and the utility model volume is little, and the generation due to bubble is generated the effect of mixing wastewater with air liquid by ultrasonic wave completely, and therefore energy consumption is little, noise is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1 micro-nano bubble generator, 2 pipelines, 3 pools, 4 biological filters, 5 exhaust inner chambers, 6 micro bubble releasing devices, 7 water shoots, 8 water distributors, 9 dreg collecting slots.
Embodiment
A kind of bacteria filter device, is characterized in that: comprise micro-nano bubble generator 1; Described micro-nano bubble generator 1 is connected to pool 3 and biological filter 4 by pipeline 2; Be provided with exhaust inner chamber 5 in described pool 3, the bottom of exhaust inner chamber 5 is provided with pipeline tapping, and the top of pipeline tapping is provided with micro bubble releasing device 6; Be provided with water shoot 7 in described pool 3, water shoot 7, through exhaust inner chamber 5, water shoot 7 is evenly distributed with opening, and water shoot 7 one end, through the side of pool 3, is connected with water distributor 8; Described water distributor 8 is arranged on the top of biological filter 4; The inside of described biological filter 4 is provided with filter material layer.Dreg collecting slot 9 is provided with above the side of pool 3.The height of exhaust inner chamber 5 is no more than 2/3rds of pool 3 height.
Specific works principle of the present utility model is: sewage is through micro-nano bubble generator 1, form micro-nano bubble therein, and make it discharge bottom pool 3, fine suspension in water is made to stick on air filled cavity, the water surface is floated to bubble, form scum silica frost, water in air flotation pool flows into water distributor 8 by the perforate on water shoot under hydraulic action, surface, biological filter 4 is evenly dispensed in by water distributor 8, sewage is put down from top to bottom in the process of filter material layer flowing, to the forced aeration that filtrate inside is carried out from bottom to top.
The utility model adopts micro-nano aeration device 1 to carry out aeration, because it can produce less bubble, add the contact area of air and water, improve the utilization ratio of oxygen, make high-activity microorganism (aerobic bacteria etc.) growth and breeding in bamboo filter material surface and internal capillary, form microbial film, effectively absorb organic pollutants as its metabolic nutritive substance, utilize the Strong oxdiative degradation capability of high-concentration biological amount to carry out fast purification process to sewage.
The utility model one is that original cloth pond is transformed into nanometer air flotation pool, also possesses cloth water function simultaneously, two is transformation aerating systems, nanometer aeration device makes water mix with gas height to mix, ultrasonic cavitation disperse discharges highdensity, uniform submicron bubble, form the gas liquid mixture of " oyster white ", this mixed gas is then the active oxygen species group with higher-energy, oxygen is after ionization, to tell that eddying motion produces cutting action, and along with high speed eddying motion produce High Pressure, ionization oxygen machining and be compressed into small bubble, and inject in water with high linear velocity, initial motion speed is formed higher in water, there is higher mobile efficiency and the active oxygen species group of mobile efficiency---high energy oxygen.Bubble median size 200nm-4um, bubble inclusion rate 84%-90%, bubble average lift velocity 4mm/s-8mm/s that this device produces.
The bubble produced due to the more common aerator of micro-nano bubble generator is much smaller, therefore increase with the contact area of water, and under the effect of energy, high energy oxygen can be dissolved in rapidly in water becomes high density dissolved oxygen, and therefore the utilization ratio of oxygen significantly improves.The utility model volume is little, and due to the generation of bubble be by ultrasonic wave, the effect of mixing wastewater with air liquid is generated completely, therefore energy consumption is little, noise is low.
The above is only preferred implementation of the present utility model, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite not departing from the utility model principle, some improvement, retouching or change can also be made, also above-mentioned technical characteristic can be combined by rights; These improve retouching, change or combination, or the design of utility model and technical scheme are directly applied to other occasion without improving, and all should be considered as protection domain of the present utility model.
