Description
Technical field
The invention belongs to technical field of electrochemistry, relate to a kind of electrochemical processing apparatus of organic waste water, particularly relate to a kind of multiple-unit integrated form electrolyzer.
Background technology
Traditional method of wastewater treatment is as effective to Normal wastewater in Physical, chemical method and biochemical process etc., but the material often containing molecular structure stabilized in pharmacy, agricultural chemicals, printing and dyeing and some wastewater from chemical industry or antibiotics, adopt traditional method to be difficult to degraded, cause the difficult point being treated as current wastewater treatment to organic wastewater with difficult degradation thereby.
Electrochemical oxidation technology belongs to the high-level oxidation technology of wastewater treatment.Because electrochemical techniques only need provide electric current in wastewater treatment process, do not need extra interpolation chemical agent, be thus extensively called " environmentally-friendly technique " both at home and abroad.
Electrochemical oxidation technology makes pollutent that Direct Electrochemistry reaction or the strong oxidizing property active substance that utilizes electrode surface to produce and pollutent generation oxidizing reaction occur on electrode, and the latter is also referred to as indirect electrochemical and reacts.Direct Electrochemistry reaction can make organic pollutant be converted into harmless object by anodic oxidation, the release of association simultaneously O
2side reaction, reduce current efficiency, but can be suppressed by the selection of electrode materials and superpotential control.Indirect electrochemical reacts the oxygenant that electrochemical reaction can be utilized to produce and (comprises HO, O
2and HO
2deng free radical), make contamination transform be innoxious substance.Electrochemical oxidation technology have simple to operate, be convenient to the simple and advantage such as can to combine with other treatment processs of Automated condtrol, reaction conditions gentleness, non-secondary pollution, aftertreatment.This technology can effectively be degraded difficult biochemical treatment waste water, shows obvious technical superiority, has become a study hotspot in field of water pollution control.But electrochemical oxidation technology also exists some problem demanding prompt solutions in actual application: one is that wastewater treatment length consuming time, treatment capacity are few, needs the current efficiency, mass-transfer performance etc. that improve electrochemical reactor badly, improve treatment capacity to reduce the treatment time; Another is that electrode life is short, needs the stability improving electrode.
In existing technology, the mainly conventional panels frame electrolyzer used in actual production.In most of the cases, because electrolytic solution is at the tank room through plate and frame electrolyzer, liquid is difficult to the flow velocity keeping uniformity, easily there is the phenomenon such as mass flow discrepancy, electrolysis dead angle, not only make the distribution of current on electrode uneven, cause Faradaic current decrease in efficiency, but also add the chance of side reaction generation.
For these problems existed, existing electrochemical reactor takes different innovative approachs, a kind ofly flowing-type electrochemical reactor is seethed for indirect electrochemical oxidation method process trade effluent as: Chinese patent CN 103408106 A discloses, comprise electrolytic cell body, electrolyte entrance, electrolyte outlet, anode, negative electrode, the electrolyte entrance of this electrochemical reactor is arranged on the upper end of electrolytic cell body side, electrolyte outlet is arranged on the lower end of electrolytic cell body opposite side, electrolytic cell body is divided into several space by dividing plate, each spatial placement pair of electrodes, dividing plate is provided with electrolyte passage, on the position of adjacent separator By Electrolysis liquid passage, under be crisscross arranged.By designing above, waste water is flowed between meshed polar plate, increase electrode specific surface area, reinforcing mass transfer, waste water constantly goes up current downflow in the reactor, further the contact reacts of strengthening strong oxidizing property species and Pollutants in Wastewater.Above-mentioned electrochemical reactor electrode is only limitted to stretching mesh electrode, and electrolytic solution can not form baffling in a cell, and fluid flow is short, and under identical flow velocity, the residence time is short, reduces single groove electrolysis effectiveness.
Chinese patent CN 102211801 A discloses a kind of electrochemical reaction appts for the treatment of high concentrated organic wastewater, and comprise electrolyzer, multiple electrode, multiple electrode is fixedly installed in electrolyzer, Electrode connection direct supply, and electrolyzer is built with electrolytic solution; Its electrolyzer inwall is provided with multiple draw-in groove for fixed electorde, by selecting the spacing of the number control electrode of interval draw-in groove, multiple electrode in electrolyzer in being staggered, serpentine flow path is formed in electrolyzer, ensureing that the time that waste water processes in a cell is the longest by designing above, improving effect of electrolytic oxidation.But the bubble that this electrochemical reaction appts electrode surface produces leaves electrode surface by buoyancy, rate of flow of fluid is slow, is difficult to realize gas-liquid separation in time, increases resistance, reduces energy efficiency.
Chinese patent CN 2545217Y discloses a kind of tubular swirl electrolyzer, and it is made up of negative electrode, anode, spiral deflector, barrier film, catholyte divider, anolyte divider, cell body, sealing member, fastening piece and corresponding supporting catholyte recycle pump, anolyte recycle pump, catholyte storage tank, anolyte storage tank, direct supply, voltage regulator etc.The problem that it had both avoided electrolytic current density skewness in smooth plate frame electrolytic tank electrolysis process and had caused current efficiency to reduce, give full play to again the characteristic that the chemical reaction efficiency of tubulose exclusion formula reactor is high, and in reaction process, make the residence time that material adds in its electrolyzer when not reducing flow velocity, electrode area is so just made relatively to be increased, thus electrolytic efficiency can be improved, but this electrolytic tank electrode is hollow edged electrode, and the processing of electrode is more difficult.
