The invention relates to an electrode plate of an inert composite electrode adopting environment friendly technology (EFT), in particular to a transition plate of the inert composite electrode, and a preparation method and application of the electrode plate. After using the electrode plate, the treated sewage can be discharged up to the standard and the service life of the electrode plate is greatly prolonged.
Description
Technical field
The present invention relates to battery lead plate, the especially rebound of inertia combined electrode of the inertia combined electrode of a kind of environmental friendliness technology (EFT, Environment Friendly Technology), the preparation method of this battery lead plate and application thereof.
Background technology
The electrochemical process water technology is called as " environmental friendliness " technology (EFT, Environment Friendly Technology.The main points of EFT electrochemical techniques are: electricity flocculation/electric floating/chemical coprecipitation technique is the electrochemical process that the redox reaction principle of Applied Electrochemistry, control are polluted.In electrolyzer, feed the direct current of certain voltage, let waste water pass through electrolyzer, make the electrolytical negatively charged ion in the waste water shift to anode, and lose electronics and oxidized at anode, positively charged ion is shifted to negative electrode, and obtains electronics and be reduced at negative electrode.Utilize this reaction to make pollutant component generate water-fast throw out, and generate gas and from water, overflow, make purification of waste water.
It is general chemical method that electrochemical process is disposed of sewage, 1/3 of method running costs such as physics method, and also technology is simple, and easy to operate, the construction work floor space is few, and disposing of sewage can qualified discharge steady in a long-term.Electrochemical method is administered sewage, has pharmaceutical chemicalss such as need not to add oxygenant, flocculation agent, and equipment volume is little, and floor space is few, advantages such as convenient and flexible operation.Energy consumption is big (uses the electric energy operation hours long but electrochemical method exists always; General more than 3 hours), high (battery lead plate consumption is fast for cost; Subject matter is passivation, the active metal electrode plate) etc. shortcoming, thereby big limitations the application of electrochemical method in field of wastewater treatment.
Under the alive outside effect, utilize the anode of solubility, produce a large amount of positively charged ions (like Fe
2+, Al
3+Deng), waste water is carried out coagulative precipitation, this method is called electrocoagulation.Electrocoagulation often is accompanied by air supporting, has hydrogen to be reduced at negative electrode, is called the floating method that goes up of electrocoagulation so also have.Electrode reaction is following:
Anode: Fe-2e → Fe
2+Or Al-3e → Al
3+
Negative electrode: 2H
++ 2e → H
2↑ or O
x+ ne → Re
In several kinds of electrochemical treatment waste water types, electrocoagulation and electric pneumatically supported utilization comparative maturity.Compare with chemical coagulation, the electrocoagulation method need not to invest the dosing facility, and materials consumption will reduce a lot.Its defective is energy consumption problem.Iron ion or aluminum ion combine to play cohesion with hydroxide radical.Simultaneously, in negative electrode generation reduction reaction, the hydrogen of effusion forms minimum bubble, with the floating fluid surface of going up electrolyzer of the condensation prod in the waste water.Electrocoagulation has obtained application very early as a kind of effective means of wastewater treatment, but because its unit aluminium, iron loss material in practical application are excessive, the development of electrocoagulation and application is restricted.
Wastewater treatment method generally adopts physico-chemical process shunting-----comprehensive two sections processing at present.Leading portion is handled three types of water of many branches; Chromium water, cyanogen water and integrated water (copper nickel zinc water).Chromium water is with the reductive agent reduction that makes it to appraise at the current rate, and cyanogen water is used the two-stage oxidation broken cyanide, and copper nickel zinc water directly merges with preceding two strands of water and is integrated water.The beol integrated water; Basically be with alkali (caustic soda or lime), Poly aluminum Chloride (PAC) (PAC) and organic floculant (PAM); Concrete operations are: adjust to 10--13 to the pH value of integrated water, alkali concn forces the reaction of alkali and heavy metal to be carried out to the direction that generates oxyhydroxide greatly.Because pH value＞9 drop to below 9 the pH value thereby drain need use acid to neutralize again.This belongs to traditional treatment process, has many deficiencies.The for example division of three sewage of pre-treatment does not meet and produces reality, and chromium water is that master, cyanogen water are that master, copper nickel zinc three Heshuis are in the majority with 3 elements with cyanogen with chromium.These practical situation are in the practice of wastewater treatment, to find, the waste water of nearly all enterprise is not always the case.Because all contaminations all exists in the sewage of second section processing, is difficult to make terminal water qualified discharge with simple pharmaceutical chemistry method.Leading portion is handled the processing requirements that can not reach reverse osmosis membrane, and treatment operating costs is high, again can not qualified discharge.The direction and goal that beol has become each tame WWT enterprise to pursue.
Simultaneously, electrochemical process is disposed of sewage in the process, after electrolysis for some time; Passivation phenomenon can take place in anode, and scale problems can take place negative electrode, and electrode surface adheres to one deck oxide film during passivation; Showing as anodic stripping stops; The sewage of handling can not qualified discharge, and electrode materials, electric energy consumption are big, and WWT running cost is high.These problems are perplexing the application of electrochemical process in the WWT production always.
And is now widely used at home and abroad, mostly soluble electrode iron, aluminum, as treated sewage Ru coagulant, but the electrode plate material consumption is too high, easy to fouling, easy to aging, life is short (about 30 days), an increase of wastewater treatment costs.
