Abstract
The utility model discloses a sewage water dephosphorizing and electrolyzing device. The device comprises a positive electrode group and a negative electrode group arranged in the sewage water; and at least one electrode of the positive electrode group and the negative electrode group adopts an iron electrode. The electrolyzing device provided by the utility model is used for dephosphorization, has the advantages of simple equipment, small occupied area and low operating cost, can be combined with the prior sewage water treatment technology for use, can meet increasingly-strict sewage water discharge standards, is suitable for dephosphorization of domestic sewage water and industrial sewage water, and realizes 60 to 95 percent of removal ratio of PO4<3->-P.
Description
Technical field
The utility model belongs to sewage water treatment method, is specifically related to a kind of sewage dephosphorization electrolyzer.
Background technology
Along with the development of society, China faces increasingly serious ecological environmental pollution, and body eutrophication is serious day by day, and China is to the control of phosphorus discharging also increasingly stringent for this reason.In order to reduce the discharging of phosphorus, the main at present phosphorus removing method that adopts of the existing sewage work of China has biological phosphate-eliminating and chemical dephosphorization.
Biological phosphate-eliminating is to make polyP bacteria carry out enrichment to phosphorus to enter mud, by spoil disposal phosphorus is removed from sewage by building certain ecotope.Biological phosphate-eliminating is in order to build the growing environment of polyP bacteria, has that facility investment is big, flow process is complicated, operation stability is poor, often is difficult to the operating performance that reaches good during actual motion.
Chemical dephosphorization is to add chemical agent in sewage, reacts to generate to precipitate by chemical agent and phosphorus phosphorus is removed from sewage.Chemical method dephosphorization equipment running cost height, the chemical sludge of generation need further to handle, otherwise may cause secondary pollution.
The utility model content
The purpose of this utility model is the problem that exists at existing phosphorus removing method, and a kind of device simple, sewage dephosphorization electrolyzer that running cost is low are provided.
Electrolyzer of the present utility model is, comprises and being located in sewage the positive and negative electrode group of (can in the equipment of various sewage processes such as anaerobic pond, anoxic pond, Aerobic Pond, trickling filter), and having an electrode in the described positive and negative electrode group at least is the ferroelectric utmost point.
An electrode is the ferroelectric utmost point in the described positive and negative electrode group, and another electrode can adopt noble electrode.
Described ferroelectric extremely can be iron plate, iron plane flower, iron filings.
Described noble electrode can adopt materials such as graphite, titanium.
Described positive and negative electrode group can be single group or many groups.
The power supply of described electrolyzer can adopt direct current or alternating-current, and power source voltage is the 1-100 volt, and electric current is the 0.01-10 ampere.
When described electrolyzer adopted direct current, positive electrode adopted the ferroelectric utmost point.
When described electrolyzer adopted alternating-current, positive electrode and negative potential all adopted the ferroelectric utmost point.
The leading-out end of the described ferroelectric utmost point can adopt inert material as graphite.
Principle of work of the present utility model:
Adding under the weak electric field, making the ferroelectric utmost point that is immersed in the sewage produce disassociation, generating ferrous ion Fe
2 +, at Fe
2+Iron ion Fe with oxidized generation
3+Acting in conjunction under, combine insoluble materials such as generating the phosphoric acid molysite with phosphate anion in the sewage, finally generate precipitation and from sewage, remove.
The utility model electrolyzer is used for dephosphorization, have device simple, floor space is little, working cost is low advantage, can be used in combination, can satisfy the sewage drainage standard of increasingly stringent with existing sewage treatment process, be applicable to the dephosphorization of sanitary sewage and industrial sewage, PO
4 3-The clearance of-P is 60-95%.
Description of drawings
Accompanying drawing is the electrolyzer synoptic diagram that the utility model method is used.
Embodiment
