Abstract
The utility model discloses a dispensing gas circulating fluidized biofilter tank. The dispensing gas circulating fluidized biofilter tank comprises a tank body, a water inlet tube, a gas inlet tube, a water drainage port and a filler device, wherein the gas inlet tube is arranged at the bottom in the tank body; and the filler device is located in the tank body, composed of filler group units formed by integrally filling ceramisites in a container with meshes, and suspended above the gas inlet tube in a fluid. According to the dispensing gas circulating fluidized biofilter tank disclosed by the utility model, the form of taking ceramisites as carriers and integrally filling the ceramisites to form the filler group units is adopted and a fluidized biofilter bed is formed by virtue of bottom aeration and water inlet flow, so that the contact between pollutants and organisms is enhanced, the oxidation speed is increased, and a carbon source in sewage is effectively utilized, therefore, a great nitrogen and phosphorus removal effect can be obtained in low-carbon-source sewage treatment without adding organic carbon source nutrients.
Description
Technical field
The utility model relates to technical field of sewage, relates in particular to a kind of biological filter of handling low carbon source sewage that is applicable to.
Background technology
Nitrogen, phosphorus are the major causes that causes the rivers and lakes eutrophication, and nitrogen, phosphorus are mainly derived from the sanitary sewage in cities and towns.In order to contain the eutrophication of surface water body, there has been more strict standard in country, thereby has needed then that for the processing of sewage higher denitrogenation dephosphorizing efficient is arranged nitrogen, the phosphorus discharging of sewage work.
Sewage adopts in the process of biological treatment, and denitrogenation dephosphorizing requires to have enough carbon sources.Conventional sewage treatment process, C/N ﹥ 5 can obtain higher denitrogenation dephosphorizing effect and reach emission request.But about 3, country sewage is then lower usually for its C/N of general sanitary sewage.For these low C/N sewage, the way of prior art is to improve the C/N value to improve the denitrogenation dephosphorizing effect by adding organic carbon source at present, obviously, adds the processing cost that organic carbon source certainly will increase sewage.For addressing this problem, in the aerobic treatment process of sewage, need to strengthen pollutent and biological contacting, accelerate oxidation rate realizes denitrogenation dephosphorizing efficient effectively to utilize the carbon source in the sewage raising, for this reason, it is most important to carry out structure setting and the treatment effect thereof of biological filter of aerobic reaction.
The utility model content
The purpose of this utility model is to overcome the deficiency of technology, a kind of dispersing gas circulating fluidization biological filter is provided, to strengthen pollutent and biological contacting, accelerate oxidation rate, effectively utilize the carbon source in the sewage, make the processing of hanging down carbon source sewage need not to add the organic carbon source trophoplasm and also can obtain good denitrogenation dephosphorizing effect.
The purpose of this utility model is achieved by the following technical programs:
A kind of dispersing gas circulating fluidization biological filter that the utility model provides comprises pond body, water inlet pipe, inlet pipe, water port, filler unit; Described inlet pipe is arranged on the bottom in the body of pond; Described filler unit is positioned at the pond body, is collected by haydite to be loaded on formed filler group unit in the container with mesh constitutes and be suspended in inlet pipe in fluid top.The utility model is carrier with the haydite, the form of adorning with filler group unit by collection is suspended in Chi Tizhong, sewage during by filler the microorganism in the sewage rest on the haydite surface and form microbial film and constantly growth, the organism under this action of microorganisms in the sewage is just degraded fully.By the bottom aeration, air-flow disperse is from bottom to up stirred filler group unit in filler group unit, make it form fluidized state at Chi Tizhong, is conducive to strengthen pollutent and biological contacting and effect in addition.
In the such scheme, container described in the utility model is column, and the suspension that is beneficial to filler group unit is stirred.Described inlet pipe is shunt pipe form arranged, is placed with production well on it, and the micro-pore aeration by the bottom is with the disperse effect of further raising gas.
Further, water inlet pipe described in the utility model pond body inner bottom part and be arranged on inlet pipe and filler unit between; Described water port is the spillway at body top, pond.Sewage enters mobile from bottom to up from pond body bottom, can support further and promote that filler group unit stirs in the suspension of Chi Tizhong, also helps to strengthen the contact probability of pollutent and biology simultaneously, loads and cuts down the consumption of energy thereby improve pollutant removal.
Further, water inlet pipe described in the utility model is shunt pipe form arranged, is placed with posticum on it.By the porous water inlet that distributes, with strengthen sewage flow and with the contacting of filler group unit.
The utlity model has following beneficial effect:
The utility model adopts the form that forms filler group unit with the haydite for carrier union dress, utilize bottom aeration and water inlet current to form fluidised bacteria bed, pollutent and biological contacting have been strengthened, improve the pollutant removal load and reduced energy consumption, effectively promoted biomembranous metabolism, thereby accelerated oxidation rate, effectively utilized the carbon source in the sewage, made the processing of hanging down carbon source sewage need not to add the organic carbon source trophoplasm and also can obtain good denitrogenation dephosphorizing effect.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is middle filler group cell schematics embodiment illustrated in fig. 1.
Among the figure: pond body 1, water inlet pipe 2, posticum 2a, inlet pipe 3, production well 3a, water port 4, haydite 5, container 6, filler group unit 7.
Embodiment
Illustrated in figures 1 and 2 is the embodiment of a kind of dispersing gas circulating fluidization of the utility model biological filter, as shown in Figure 1, comprises pond body 1, water inlet pipe 2, inlet pipe 3, water port 4, filler unit.Wherein, inlet pipe 3 is arranged on the bottom in the pond body 1, is shunt pipe form arranged, is placed with production well 3a on it.Filler unit is positioned at pond body 1, is 0.85g/cm by density
3Haydite 5 collection be loaded on that formed filler group unit 7(sees Fig. 2 in the column shape container 6 with mesh) constitute and in fluid, be suspended in the top of inlet pipe 3.Water inlet pipe 2 is shunt pipe form arranged between inlet pipe 3 and filler unit, is placed with posticum 2a on it.Water port 4 is the spillway at pond body 1 top.
It is the form that carrier union dress forms filler group unit 7 that present embodiment adopts with haydite 5, utilizes the promotion of bottom aeration and water inlet current to form fluidised bacteria bed.When filler unit when the packing fraction of Chi Tizhong is 50~70V%, under the condition of identical pollutant load, the COD clearance has improved 20~30% than conventional activated sludge method; Under the condition that guarantees qualified effluent quality, the pollutant load rate has improved 2~2.5 times.
