Description
Technical field
This utility model is related to a kind of phosphorous remover, and in particular to a kind of biological phosphate-eliminating device in biochemical wastewater treatment.
Background technology
Phosphorus be all life body necessary to nutrient, while and be body eutrophication " arch-criminal ", it is in sewage, special
Not for sanitary sewage, substantial amounts of phosphorus is there is, therefore, in sewage disposal process need to remove phosphorus.
At present, the method for dephosphorization is gone to be mainly biological dephosphorization and chemical precipitation dephosphorization method.So-called chemical precipitation dephosphorization is
By the phosphorus (mainly in the form of orthophosphate) in sewage, removed (such as by forming chemical precipitation with aluminium salt and iron salt
Aluminum phosphate or magnesium phosphate).And biological phosphate-eliminating is by anaerobic pond and Aerobic Pond are arranged in processing technological flow, in anaerobic pond
PolyP bacteria will suck volatile fatty acid (VFA) and is stored in cell body in the form of beta-hydroxy-butanoic acid (PHB), work as mixed liquor
When entering into Aerobic Pond, storing the PHB in polyP bacteria body is used for the growth of polyP bacteria, while substantial amounts of phosphate in water is absorbed,
At this moment the polyP bacteria in Aerobic Pond has the Quadrafos of high content, by by outside excess sludge discharge system, it is possible to achieve
Biological phosphate-eliminating.
The deficiency that chemical precipitation dephosphorization method is present has：1. by going remove divided by the phosphorus of orthophosphate form
The phosphorus of other forms (such as organophosphors)；2. need to add water treatment agent (such as aluminium salt and iron salt), and these medicaments will be to some
Special biological treatment (such as causing dirty stifled to the film of MBR) brings certain puzzlement；3. handling process is long, and investment is big.
And biological phosphate-eliminating there is also following deficiency：The activated sludge of large losses is needed, biological treatment system is affected
Stability, system activity sludge concentration reduce.
Utility model content
Technical problem to be solved in the utility model is to provide one kind and can guarantee that phosphor-removing effect and without the need for the remaining dirt of discharge
Mud, need not add dephosphorization water treatment agent for the biological phosphate-eliminating device in biochemical wastewater treatment.
In order to solve above-mentioned technical problem, this utility model provide for the biological phosphate-eliminating device in biochemical wastewater treatment,
Match the lid being connected including housing and with described housing, and described housing is provided with entry to mixed solution；Described housing
Interior intracavity be provided with a slurry filter and be formed with space between described slurry filter and described housing；Ejector
Entrance in the described slurry filter, the outlet of described ejector is connected with outlet, is passed through by the first valve
Second valve is connected with high phosphorus water out；Described ejector is connected with compressed air hose and described compressed air hose and is equipped with
3rd valve.
The filtering accuracy of described slurry filter is about 0.1-1.0mm.
The first described valve is automatic valve.
The second described valve is automatic valve.
The 3rd described valve is automatic valve.
Described entry to mixed solution is located at the bottom of described housing.
Described entry to mixed solution is located at the axial centre position of the bottom of described housing.
Axial centre position of the described slurry filter in the inner chamber of described housing.
Described housing is cylindrical structural.
The axial centre position of the inner chamber in described slurry filter of described ejector.
Using above-mentioned technical proposal for the biological phosphate-eliminating device in biochemical wastewater treatment, be installed in sewage disposal system
Aerobic Pond in, its filtering accuracy is about 0.1-1.0mm, can realize the separation of activated sludge and water；The water outlet of outlet is directly arranged
Enter in Aerobic Pond, and the water outlet of high phosphorus water out is then outside discharge system；The mixed liquor of activated sludge and sewage passes through ejector
Negative pressure is produced in the presence of compressed air, is continuously entered in housing from entry to mixed solution, in slurry filter
Under interception, activated sludge is intercepted in the space between slurry filter and housing, water through slurry filter, outlet,
It is drained in Aerobic Pond after first valve and outlet.After the time of setting is lasted till, stop the entrance of mixed liquor.Due to dephosphorization
Device and Aerobic Pond lie substantially in isolation, and oxygen is difficult to enter in housing, simultaneously because activated sludge concentration is very high in housing,
Activated sludge will be in anaerobic state, and at this moment, the sludge in housing will discharge substantial amounts of phosphorus to water body.Set when lasting till
After the fixed time, compressed air is entered from compressed air hose, by ejector and outlet by the liquid in housing finally from
Second valve and high phosphorus water out are discharged to outside system, and at this moment the first valve is closed.Discharge from high phosphorus water out
Water phosphorus content is very high, the phosphorus in system is constantly removed.
After dephosphorization, the first valve and the second valve are closed, continuation is filled with compressed air from compressed air hose, by housing
Sludge after dephosphorization is discharged in Aerobic Pond from entry to mixed solution.
So far, a dephosphorization working cycle complete, so go round and begin again.
This utility model with the total phosphorus in depth dephosphorization sewage as target, with without the need for discharging excess sludge to outside system,
Biological treatment system activated sludge concentration is not affected, can be not required to add dephosphorization water treatment agent；It is simple for structure, flexibly.
In sum, this utility model is that one kind can guarantee that phosphor-removing effect and need not discharge excess sludge, need not add and remove
Phosphorus water treatment agent for the biological phosphate-eliminating device in biochemical wastewater treatment.
