Description
Technical field
The invention belongs to technical field of electrochemistry, relate to the electrochemical processing apparatus of a kind of organic wastewater, particularly relate to
A kind of multiple-unit integrated form electrolysis bath.
Background technology
Traditional method of wastewater treatment such as Physical, chemical method and biochemical process etc. is effective to Normal wastewater, but pharmacy, agriculture
Medicine, printing and dyeing and some wastewater from chemical industry often contain material or the antibiotics of molecular structure stabilized, uses traditional method to be difficult to
Degraded, causes and organic wastewater with difficult degradation thereby is treated as the difficult point that current waste water processes.
Electrochemical oxidation technology belongs to the high-level oxidation technology that waste water processes.Owing to electrochemical techniques are at wastewater treatment process
In only need to provide electric current, it is not necessary to extra interpolation chemical agent, thus be widely referred to as " environmentally-friendly technique " both at home and abroad.
Electrochemical oxidation technology is to make pollutant Direct Electrochemistry reaction occur on electrode or utilize electrode surface to produce
Strong oxidizing property active substance and pollutant generation oxidation reaction, the latter is also referred to as indirect electrochemical reaction.Direct Electrochemistry
Reaction can make organic pollution be converted into harmless object by anodic oxidation, the release O of association simultaneously2Side reaction, reduce electric current effect
Rate, but the selection and superpotential control by electrode material can be suppressed.The available electrochemistry of indirect electrochemical reaction is anti-
The oxidant that should produce (includes HO, O2And HO2Deng free radical), make pollutant be converted into innocuous substance.Electrochemical oxidation
Technology have simple to operate, to be easy to Automated condtrol, reaction condition gentleness, non-secondary pollution, post processing simple and can be with other
The advantages such as processing method combines.This technology can effectively be degraded difficult biochemical treatment waste water, shows obvious technical advantage, becomes
A study hotspot in field of water pollution control.But electrochemical oxidation technology there is also some urgently in actual application
The problem solved: one is that waste water process is the longest, treating capacity is few, needs the raising current efficiency of electrochemical reactor, mass transfer performances badly
Can wait, process time raising treating capacity with reduction；Another is that electrode life is short, needs to improve the stability of electrode.
In existing technology, the mainly conventional panels frame electrolysis bath used in actual production.In most of the cases,
Owing to electrolyte is at the tank house through plate and frame electrolysis bath, liquid is difficult to keep the flow velocity of uniformity, stream easily occurs
The phenomenons such as amount is uneven, electrolysis dead angle, not only make the CURRENT DISTRIBUTION on electrode uneven, cause Faradaic current efficiency to decline, and
Also add the chance that side reaction occurs.
For these problems existed, existing electrochemical reactor takes different corrective measures, such as: Chinese patent
CN 103408106 A disclose a kind of for indirect electrochemical oxidation method process industrial wastewater to seethe flow-type electrochemistry anti-
Answering device, including electrolytic cell body, electrolyte entrance, electrolyte outlet, anode, negative electrode, the electrolyte of this electrochemical reactor enters
Mouth is arranged on the upper end of electrolytic cell body side, and electrolyte outlet is arranged on the lower end of electrolytic cell body opposite side, electrolytic bath
Body is divided into several space by dividing plate, and each space arranges pair of electrodes, and dividing plate is provided with electrolyte passage, and adjacent separator powers on
The position of solution liquid passage is upper and lower to be crisscross arranged.Make waste water flow between meshed polar plate by above design, increase electrode specific surface
Long-pending, strengthen mass transfer, waste water constantly flows in the reactor up and down, further strengthening strong oxidizing property species and Pollutants in Wastewater
Haptoreaction.Above-mentioned electrochemical reactor electrode is only limitted to stretch mesh electrode, and electrolyte can not form baffling in a cell,
Fluid flow is short, and under identical flow velocity, the time of staying is short, reduces single cavity electrolysis effectiveness.
Chinese patent CN 102211801 A discloses a kind of electrochemical reaction dress for processing high concentrated organic wastewater
Putting, including electrolysis bath, multiple electrode, multiple electrodes are fixedly installed in electrolysis bath, and electrode connects DC source, and electrolysis bath is built-in
There is electrolyte；Its electrolysis bath inwall is provided with multiple draw-in groove for fixed electrode, by selecting the number of interval draw-in groove to control electricity
The spacing of pole, multiple electrodes in being staggered, form serpentine flow path, by designing guarantee above in electrolysis bath in electrolysis bath
The time that waste water processes in a cell is the longest, improves effect of electrolytic oxidation.But this electrochemical reaction appts electrode surface produces
Raw bubble leaves electrode surface by buoyancy, and rate of flow of fluid is slow, it is difficult to realize gas-liquid separation in time, increases resistance, reduces energy
Amount efficiency.
Chinese patent CN 2545217Y discloses a kind of tubular swirl electrolyzer, and it is by negative electrode, anode, spiral stream guidance
Plate, barrier film, catholyte allotter, anolyte allotter, cell body, sealing member, securing member and the most supporting catholyte
Circulating pump, anolyte circulating pump, catholyte storage tank, anolyte storage tank, DC source, voltage regulator etc. form.It was both avoided
Electrolytic current density skewness during surface plate frame electrolytic tank electrolysis and cause the problem that current efficiency reduces,
Give full play to the characteristic that the chemical reaction efficiency of tubulose exclusion formula reactor is high, and made material not drop in course of reaction
Add the time of staying in its electrolysis bath in the case of low flow velocity, thus make electrode area relatively be increased, because of
And electrolytic efficiency can be improved, but this electrolyzer electric extremely hollow edged electrode, the processing of electrode is relatively difficult.
