According to system group prejudice figure -2 designed by process flow
Present treatment system is made of three parts, it may be assumed that host, ASBR, SBR.
Host is the core processing equipment of present treatment system.It is again by PLC program control subsystem, UV/TiO2+O3+H2O2
Processing subsystem, gas active charcoal adsorption subsystem, diaphragm electrodialysis subsystem, the automatically controlled subsystem of panel five are cooperateed with electrolysis
System altitude is integrated in all steel cabinet of 480 × 480 × 1500mm of size, forms a floor mounted equipment,
Inner part is configured in floor shape, liquid waste processing capacity 20L/ times.
It handles host and uses state-of-the-art low-voltage low frequency high current in the current water treatment technology created by us
Based on " alternation " pulse electrochemical water treatment technology, the three kinds of electrolysis modes and ozone connected on the period with three are in same electricity
It solves in slot and efficient collaboration processing is carried out to waste liquid, then go here and there with UV/TiO2+O3+H2O2Link, will be in waste liquid within 6 hours
CODcr removal 80%~90%, by total Cr6+It is removed to and is less than primary pollutant highest permission discharge standard (≤0.5mg/L)；Benzene
Amine degradation is removed to less than three-level emission standard (≤5mg/L).Entire electrolytic process uses more advanced PLC program control
Make and realize the automation of electrolytic treatment phase.Escaping gas is inhaled by negative-pressure ward into active carbon in electrolytic process
It tells.Treated that water is clarified for electrolysis, and after entering diaphragm electrodialysis system desalination, is finally completed the processing task of host.It is whole
A host is exactly one by several current advanced water treatment technology cell height organic integration, and efficient, practical integration is set
Standby, the integration apparatus for handling ultrahigh concentration, high toxicity, high salinity waste water at normal temperatures and pressures both at home and abroad has been filled up in its appearance
Blank.
ASBR is the english abbreviation of " anaerobic active sludge bioreactor ", it is current high concentration organic sewage
The most easily-controllable form in turn at first of anaerobic degradation.
Although host by the contaminant removal in waste water 80%~90%, since so-and-so chemically examines waste liquid category superelevation
The special waste liquid of concentration, CODcr reach as high as 300 000mg/L, therefore even if obtaining the efficient process of host, remaining
CODcr still has 20 000~60 000mg/L, and the numerical value is still the raw water outside Now Domestic in general water process concept
Upper limit value, it is therefore necessary to continue with.Since electrolysis processing has shortened the carbochain of Long carbon chain or the organic matter of aromatic,
Residual organic substances are made to be quite suitable for biological treatment, and in contrast, the high-level oxidation technology processing in host is difficult to degrade to be had
Machine object effect is obvious, and handles simple organic then effect is not significant.Therefore subsequent processing is designed as biological treatment.
ASBR reactor is to be easy to be 200L, and the closed reactor of (500 × 500 × 1500mm) is recycled using water pump
Stirring (or mechanical stirring) promotes water and full and uniform mix of anaerobic activated sludge therein and guarantees anaerobic bacteria to pollutant
Efficient-decomposition.It is just natural after electrolysis treated waste liquid (000~60 000mg/L of 20L, CODcr=20) enters ASBR
10 times of dilution, becomes 2 000~6 000mg/L, CODcr removal rate was designed as 40% (deliberately allowing some leeway), then at ASBR
Water outlet CODcr after reason is designed as 1200~3 600mg/L.
SBR is the english abbreviation of " batch type aerobic activated sludge process or reactor ", capacity 100L, (500 × 500 ×
700mm), oxygen needed for providing biochemical degradation organic matter to aerobic activated sludge bacterium using blast aeration form.Aerobic
Under the biochemical action of activated sludge bacterium, the Organic substance in water that gives up obtains further degradation.Designing its CODcr removal rate is 50%
(consideration of allowing some leeway takes lower value to design).After entering SBR from ASBR discharge water (daily discharge capacity 20L), it is diluted 5 naturally
Times, 1 200~3 600mg/L when then the CODcr after its dilution is discharged from ASBR become 240~720mg/L, Jing Qijin mono-
Step degradation, so that it is discharged CODcr becomes 170~300mg/L.Under relatively better mode of operation, CODcr has been much smaller than row
Enter three-level discharge standard (CODcr≤1 000mg/L, total Cr≤1.5mg/L, Cr that sewer should reach6+≤ 0.5mg/L, aniline
Class≤5mg/L), therefore sewer can be entered with direct emission.
Why in the design no matter all there are larger leeway on capacity or on degradation capability by ASBR and SBR, but consider
If to round-the-clock continuous operation into their internal inevitable accumulation for generating CODcr, that is, the CODcr handled increases at any time
Greatly, it is therefore necessary to have leeway.
The equipment of system is mainly made of host (including trunk and auxiliary system), ASBR, SBR, such as Fig. 3.
Specifically, a kind of laboratory waste liquor treatment equipment, including host, ASBR device and SBR device；The host packet
Include electric apparatus room and ozone generator room 2, electrolysis transformer 3, electrolysis unit 4, pump chamber 6, water tank 7, raw water box 12,13 and of settling tank

Host is the core equipment of present treatment system, has been internally integrated current unique " UV/TiO both at home and abroad2+O3
+H2O2Cooperate with alternating impulse electrochemical water treatment technology " and PLC program control technology, realize intelligentized control method.
Control mode: ozone adds three sections of alternating impulse electrolysis to control rest part with plate face electrically by keying with PLC program
System
This host uses alternating impulse and is electrolysed power supply, which can thoroughly overcome the unvanquishable electricity of other power supply institutes
The polarization of pole and passivation phenomenon, therefore ensure that the high efficiency of electrochemical treatment process.Herein on basis, and in electrolytic cell
Introduce O3It causes ozone strong oxidizing effect to cooperate with electrolysis Strong oxdiative/cohesion coupling, more enhances treatment effeciency.It closes
It is had not been reported both at home and abroad so far in addition to the present invention in ozone cooperative alternating pulse chemical treatment method.In host then into
Capable technique is UV/TiO2+O3+H2O2Processing, which is the phenyl amines organic pollutant in order to guarantee extremely difficult degradation
Removal rate is up to standard.
Host trunk process working principle
Reaction mechanism involved in process of this host using a variety of high-level oxidation technology Combined Treatment waste water is sufficiently complex,
But according to existing documents and materials, substantially it can speculatively be summed up in the following categories reaction:
1. the generation of ferrate and the strong oxidation to Organic Pollutants
Ferrate is oxidant more stronger than potassium bichromate and potassium permanganate, it can be with oxidizing alcohol, phenol, aniline
Class and the nitro compound even inorganic compounds such as hydro carbons organic compound and sulfide, ammonia, cyanogen.Ferrate is in entire pH
There is extremely strong oxidation in the range of value.
It needs when propellant powder chemical examination measurement using a large amount of lye, so waste liquid in most cases pH > 12, then
In the electrolysis of first segment alternating impulse, the reaction for generating ferrate has occurred first:
Anode reaction: Fe+8OH—→FexOynH2O
→FeO4 2++4H2O+6e
Fe3++8OH—→FexOy+nH2O
→FeO4 2++4H2O+6e
Cathode reaction: 2H2O→H2+2OH—–2e
Overall reaction: Fe+2OH—+2H2O→FeO4 2++3H2
2Fe3++10OH-→FeO4 2++2H2O+3H2
As ferrate root FeO4 2+Once generating, that is, take place by Fe (IV) ion through generating Fe (V), Fe (IV) is straight
To the reaction for ultimately generating Fe (III):
FeO4 2++H2O→Fe(OH)3+[O]
[O]+H2O→2HO·
2HO·→H2O2
2H2O2→2H2O
There is Hydroxyl radical HO generation in this reaction, then the HO collaboration ferrate with extremely strong oxidisability is straight
Strong oxidizing property is connect, strong oxidation reaction has been carried out to the complicated organic matter of difficult for biological degradation in water jointly, causes having for complexity
The open loop of machine object, chain rupture become carboxylic acid, are further oxidized to carbon dioxide and water.As above being shown for ferrate is strong
The organic matters such as glycerine, diphenylamines and dimethyl acardite (centralite) are largely decomposed in oxidation reaction chemical examination waste liquid
Key reaction.The main reaction is as mentioned-above " alkaline electrolysis ".
2. the electro-coagulation of iron electrode (anode)
In electrolytic process, iron anode constantly melts, and in the hydroxyl radical free radical that is subsequently generated for generating ferrate
In reaction or pass through, direct oxidation reaction generates Fe (OH)3Flocculant, it can promote water-borne glue state impurity flocculation sedimentation and realize
With the separation of water.Therefore it is that the reaction is removed that so-and-so, which chemically examines the colloidal substance in waste liquid,.
3. the redox reaction in iron electrode
A. in electrolytic process, by the ferrous ion Fe generated on Fe anode2+It is strong reductant, it in acid condition can be
Cr in water6+It is reduced to Cr3+, it is allowed to toxicity reduction, and with Fe (OH)3Precipitating is separated from water:
Cr2O7 2++6Fe2++14H+→2Cr3++6Fe3++7H2O
The purpose of aforementioned " acidic electrolysis " utilizes this principle by Cr6+Become the smaller Cr of toxicity3+And by cohesion iron clamp band
It removes.
B. ferritic reaction is generated in electrolytic process
This is the highly effective reaction for going numerous heavy metal ion in water removal.After iron electrode generates ferrous ion, in alkali
Property under the conditions of, and have in the system of NaClO, it may occur that following reaction:
(3–x)Fe2++xM2++6OH—→Fe3–xMx(OH)6
Fe3–xMx(OH)6+NaClO→MxFe3–xO4+NaCl+3H2O
In the reaction, divalent heavy metal ions (M2+) replace situation FeOFe2O3In Fe2+After be firmly bonded to knot
On crystalline substance, it is difficult to be redissolved.And in this course, since the effects of physics and attached chemical absorbing makes Cr6+And Cr3+It is a variety of
Heavy metal ion especially be also fixed in ferrite together, eventually become black ferrite particle precipitating and by heavy metal from
Son is removed from water.And the solidfied material of this heavy metal ion be it is permanent insoluble so that Cr6+And Cr3+It is able to thorough
It removes at bottom.
The reaction is also to chemically examine Cr in waste liquid to remove so-and-so in first stage " alkaline electrolysis "6+And Cr3+Principle.
Based on the above electrochemical reaction mechanism, the reasonability of " three sections of electrolysis " design is simply proved below.
I alkaline electrolysis
Strong oxidizer ferrate is generated under basic conditions, and then generates hydroxyl radical free radical, together with ferrate sheet
The strong oxidizing property of body, in waste water glycerol, aniline type organic into draw Strong oxdiative degradation；At the same time, it is also produced in electrolytic cell
It generates Fe (OH)3Flocculant and ferritic reaction, thus make colloid and heavy metal ion (Cr6+、Cr3+) it is able to precipitating clearly
It removes.It can be seen that the importance of " alkaline electrolysis " step.
II acidic electrolysis
When alkaline electrolysis setting time finishes, H is added into electrolytic cell for procedure auto-control drug delivery device2SO4Make PH≤4,
Remaining Cr in water at this time6+It can be by Fe2+It is reduced to the Cr of small toxicity3+, and make some substances for being not suitable for removing under alkaline condition
Further precipitated by removing.Therefore " acidic electrolysis " is the supplement to alkaline electrolysis.
III plus Ca2+Electrolysis
Ca (OH) is added into electrolytic cell automatically immediately after PLC ends automatically acidic electrolysis2Solution then generates a large amount of
CaSO4Precipitating, CaSO4Again by Cr remaining in water during crystallization3+Etc. heavy metal ion be solidificated in its solidifying body and
Precipitating, plays the role of further purifying.
And in three sections of electrolytic processes, all there is the reaction for generating ferrite to remove heavy metal ion simultaneously.
It can be seen that three sections of electrolysis are that progressive supplement is indispensable mutually, one section of effect for all making electrolysis clear the pollution off is lacked
Rate reduces.
4. the generation of ozone and its Strong oxdiative reaction to pollutant
In three sections of electrolytic processes, end from beginning is all accompanied by the reaction of ozone strong oxidizing degradation of organic substances, the strong oxygen of ozone
Change and Strong oxdiative/cohesion of electrochemistry is reinforced mutually and constitutes the strength degradation to pollutant and efficiently remove.
The ozone obtained by high-voltage corona discharge is decomposed in water with the mode of chain reaction, generates alkyl certainly
By base with oxidation of organic compounds, such as:
O3+OH—→HO2 2-+O2
O3+HO2 2-→HO·+O2 -+O2
O3+NH3→Qs(contain NO3 -Or NO2 -Product) (when pH is low)
HO·+NH3→Qs(contain NO3 -Or NO2 -Product) (when pH high)
From the above, it can be seen that: during " alkaline electrolysis " and " add Ca2+During electrolysis ", mainly by O3Decompose generation
HO aoxidizes organic matter, and during " acidic electrolysis ", then mainly O3Molecule directly aoxidizes organic matter.
