Processing with virose waste water has some limitations.With the fast development of industry, black liquid, dyeing waste water, contain
The discharge capacity of the hardly possible biochemical treatment waste water such as phenols wastewater, pharmacy waste water increases year by year, and increasingly strict with environmental regulation,
The improvement of this effluent part increasingly attracts attention.
Electrochemical method begins one's study application in the forties in last century, and electrochemical oxidation is to be put into organic matter in a cell
Solution or suspension, obtaining electronics on anode by direct current makes oxidation operation, or is first oxidized to low-valent metal
High volence metal ion, the method that then high volence metal ion reoxidizes organic matter.Electrochemical oxidation can be divided into Direct Electrolysis oxygen
Change and indirect electrolytic oxidation.Salinity in waste water can contribute to the conduction of solution as electrolyte.Therefore, using electrochemistry
Method handle the advantage of above-mentioned used water difficult to degradate clearly.With the development of electrochemical techniques, by being deposited on electrode
Various metal oxides turn into study hotspot as catalyst with the catalytic electrolysis for improving oxidation effectiveness.At catalytic electrolysis method
The advantage of reason technology is：1) salt in waste water can be as electrolyte, and some of which ion may also participate in oxidation, raising processing
Effect；2) hydroxyl radical free radical produced during electrolytic catalysis can be with almost all of organic pollution in oxidized waste water, especially
It is the material of some difficult degradations, so as to reduce waste water COD, or improves the bioavailable degree of waste water；3) treatment effeciency is high, and raw
Thing method is compared to the less demanding of waste water raw water, it is not necessary to be diluted and acid-base neutralization；4) individually processing can be both used as
Equipment, can also be used in combination with other techniques or equipment.It can be seen that, catalytic electrolysis treatment technology has simple to operate, nothing two
The features such as secondary pollution and wide environment compatibility, it is referred to as " environment-friendly " technology.
But due in terms of power consumption, the treatment effeciency, the development of catalytic electrolysis method is relatively slower always, industrialization
The device of application is considerably less.On the one hand the research to catalytic electrolysis equipment be the different electrode material of research at present, improves electrode
Performance, service life and the reduction energy consumption of material surface；On the other hand it is by changing electrode spacing, improving treatment effeciency etc..
By changing flowing of the waste water in reactor, waste water and electrode surface is set fully to contact, to improve grinding in terms for the treatment of effeciency
Study carefully less.During catalytic electrolysis, the catalysis oxidation and ion of organic matter lose the reaction such as electronics all to be occurred in electrode surface,
Substantial amounts of bubble is produced during the course of the reaction, causes electrode and waste water area to reduce.Many researchers do electrode surface
Into holey, to improve the specific surface area of electrode surface, but treatment effect is still undesirable.
Therefore, it is necessary to provide a kind of efficient catalytic electrolytic waste water treatment equipment, waste water and electrode surface is set fully to connect
Touch, improve catalytic oxidation treatment efficiency.
The content of the invention
The technical problems to be solved in the utility model is how to overcome the deficiencies in the prior art electric there is provided a kind of new catalytic
Solve wastewater treatment equipment.
The technical scheme that the utility model is used to achieve the above object is：A kind of new catalytic electrolysis wastewater processing dress
Put, include shell, two back covers and the agitating device above and below shell of cylinder, the agitating device is fixed on back cover center
Stirring rod on position, the agitating device is goed deep into shell, and electrode, the upper end insertion of the electrode are also installed in the shell
And on being fixed on and binding, water inlet and effluent overflow weir water are set on shell.
Further, the electrode several, distribution spaced apart, and circle distribution arrange, it is further, described
Two layers of circle distribution arrangement is presented in electrode.
Another scheme is that the electrode is distributed in shell around stirring rod in array, and especially described electrode is outside
Shell annular array distribution, can be one layer or Multi-layers distributing.
Further, the housing can be spherical, cylindrical or cube shaped.Furthermore, the electrode machining Cheng Yuan
Arc or flat board, anode and cathode are parallel.
The characteristics of the utility model is simple in construction, and treatment effeciency is high.Water is set to be rotated around electrode surface by stirring, can
To be effectively increased the contacting efficiency of waste water and electrode surface, the processing of the treatment effeciency and reactor of unit volume reactor is improved
Ability, the volume of reactor is effectively reduced in the case where processing task is certain, with serious pollution printing and dyeing are can be widely applied to useless
The processing of water, paper waste and phenol wastewater grade high salinity, high chroma and difficult degradation toxic wastewater.
Brief description of the drawings
Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, wherein：
Fig. 1 is electrolytic processing apparatus front view.
Fig. 2 is electrolytic processing apparatus cross-sectional view.
