Description
Technical field
The present invention relates to sewage treatment area, especially a kind of automatic backwash siphon filtering dephosphorization apparatus.
Background technology
In villages and small towns decentralized type sewage processing system and dispersed miniature industrial wastewater treatment system, due to contained in sewage
Nitrifier and the sludge age of polyP bacteria there is gap, therefore it for sewage when carrying out biological treatment, denitrogenation and dephosphorization
Processing is conflicting；Common sewage disposal means are preferentially to meet denitrogenation target, then pass through other additional backmans
Skill, such as chemical dephosphorization, electrolysis dephosphorization, make water outlet meet the pollutant emission standard of water outlet phosphorus.However, above-mentioned auxiliary process exists
In heavy civil sewage treatment facility, management means and fund input by specialty can obtain relatively good operation；But
It is in villages and small towns decentralized type sewage processing system and dispersed miniature industrial wastewater treatment system, due to managerial skills and O＆M money
, usually there is situation about can not normally be run because lacking effective periodic maintenance in the limitation of gold.
Relatively conventional irony waste material dephosphorization is, using the irony waste material filling filter bed such as iron plane flower, to lead in existing dephosphorization process
Sewage and the internal phosphate of its in filter bed contact process and the molten DO collective effects deposited in iron ion and water are crossed, to realize dephosphorization.
The collective effect is commonly referred to as Inner electrolysis or light electrolysis.However, after filter bed runs a period of time, the microorganism in sewage is in iron
Because biofilm is acted on matter waste material, one layer of organic matter for being referred to as biomembrane is formed, as biomembrane is constantly thickening, it can not only lead
Cause flow velocity of the sewage in filter bed too low and be unable to reach the treating capacity of design, and can due to irony scraped surface Inner electrolysis/
Light electrolysis effect is failed and influences its phosphor-removing effect.For above situation, existing solution technique is that periodically irony waste material is filled out
Fill filter bed to be dismantled, cleaned or replacing processing, it not only needs to expend suitable manpower and materials, and for villages and small towns distributing
In sewage disposal system and dispersed miniature industrial wastewater treatment system, often because follow-up maintenance can not be implemented and cause dirt
The failure of water treatment system.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of dephosphorization apparatus, it can be carried out in the filtering dephosphorization process of sewage
During the automatic cleaning treatment of external system intervention is proceeded without for dephosphorization material, to ensure that it keeps good filtering
While phosphor-removing effect so that maintenance cost is significantly improved.
In order to solve the above technical problems, filtering dephosphorization apparatus the present invention relates to a kind of automatic backwash siphon, it includes
Body is filtered, it is internally provided among irony waste material packed layer, the filtering body, the upper end of irony waste material packed layer is set

To the first pipeline section and the 3rd pipeline section extended, during make it that the siphonage in the application is triggered, the first inner tube segment
Liquid stream formation full-section pipe-flow, causes the flow velocity of its internal liquid to be improved with flow, and then causes filtered solution liquid-collecting bin indirectly
Interior water purification also improves therewith relative to the flow in irony waste material packed layer backwash process with flow velocity；Above-mentioned phenomenon is that may be such that
The backwash effect of irony waste material packed layer is able to further improve.
As a modification of the present invention, among the backwash siphon piping, institute between the first pipeline section and the second pipeline section
It it is 120 to 150 ° into angular range.Using above-mentioned technical proposal, the inclination angle that it can be by the second pipeline section relative to the first pipeline section
Degree sets the response efficiency for causing it when triggering siphonage to be improved.
As a modification of the present invention, siphon destructive pipeline is connected among the backwash siphon piping, it is connected
The link position of the second pipeline section and the 3rd pipeline section in backwash siphon piping, the end of siphon destructive pipeline extends to backwash
Among groove.Using above-mentioned technical proposal, when the automatic backwash siphon filtering dephosphorization apparatus in the application triggers siphonage simultaneously
Carried out for irony waste material packed layer in backwash processing procedure, when the liquid level in recoil washing trough is less than the end of siphon destructive pipeline
During portion, the liquid in backwash siphon piping is that can be entered to by siphon destructive pipeline inside recoil washing trough, and then is caused anti-
Wash siphon road is stopped, that is, make it that backwash process is stopped.The setting of above-mentioned siphon destructive pipeline may be such that this
Backwash technique in application is terminated automatically based on the level change in recoil washing trough, until recoil washing trough inside liquid level is rear
Recover in continuous filtration treatment to high-end trim, and then cause the backwash technique in the application to carry out automatic cycle.
