The numerous floccule body particulate matters formed between pole plate largely will be attached between two-plate so that pole plate effective area is smaller, weakens phase
The electrolytic efficiency of pollutant matrix between adjacent pole plate；In addition, caused a large amount of gases are by with the shape of micro-bubble in electrode process
Formula is collided with the tiny suspension flco in space and combined, and will certainly influence its flocculation, coagulation effect；
Existing electrocatalytic oxidation equipment its internal electrode plate electrode is easily because of metal ion oxide caused by electrolytic process
Attachment with nonmetallic ion oxide and attachment measure is eliminated without corresponding, easily cause the generation of pole plate passivation.
Existing electrocatalytic oxidation equipment does not possess to the regulation homogeneous work(under water inlet pollutant concentration unstable state
Can, under the conditions of limited electrolysis time and electrolyte space, electrolysis effectiveness is extremely unstable.

Putting can be back to the stain disease handled well again into water homogenisation room, the pollutant substrate concentration in effectively can diluting and intake,
To ensure that electrolysis installation electrolysis effectiveness stability and high efficiency plays.A kind of EPT high concentrated organic wastewaters processing electro-catalysis in the present invention
The correlative study of oxidation furnaces is not yet reported for work at present, is actually initiated.
With reference to operation principle, the invention will be further described：
First, the boosted pumping action of stain disease is promoted into water homogenisation room, water inlet be provided with electrolysis add mouth (can
Electrolyte solution is carried out according to being actually needed), stirred into the stain disease in homogeneous room and the mixed solution of electrolyte in homogeneous
Mix and homogeneous and mixing are realized under the stirring action of machine, and then composite waste is entered in electrode reaction room, now composite waste
Contacted mixing is carried out under the collective effect of Aeration system with phegma, and electrode reaction chamber interior participate in negative electrode,
Anode electrolysis is reacted, and caused scum silica frost will be realized under the automatic running of reciprocating slag-water separation system and struck off during this, is given up
The suspension containing larger particles is gradually deposited at the bottom of electrode reaction room by the effect of flocculation coagulation in water, and by periodically arranging
Mud mode is discharged from system.Secondly, the mixed liquor water outlet containing little particle suspension is then flowed through to flocculating setting room, and at this
Flocculation and the coagulation process of numerous flcos are participated in room, scum silica frost is struck off by reciprocating slag-water separation system, in waste water solution
Grain flco is constantly deposited in device bottom with other free state flcos copolymerization of surrounding, through spoil disposal exhausting pipeline discharge system.Most
Eventually, the wastewater supernatant fluid after electrolysis is handled then is entered in clean water chamber by outlet pipe overflow of perforating, and finally realizes stain disease
Effectively degraded and purification.It will be emitted into addition, part clear water will be back into water homogenisation room, another part again as recirculated water
Next stage is further processed.Whole electrolytic process will realize that its is automatic under the effect of the PLC control system of random arrangement
Change operation.
The specific control modes of its PLC are：
The present invention is realized to each processing equipment by PLC automated programming systems and controlled.Its concrete operating principle is as follows：It is first
First, into the PLC control system page, display system automatic running and system run two kinds of operational modes manually, click on system certainly
Dynamic button, will enter automatic running pattern, and now, inlet water lifting pumps carry out continuous water supply under PLC control system effect, are lifted
Pump sets corresponding low liquid level delay protection and high level protection；When the stain disease in winding shaft is in low liquid level, PLC is received
Low liquid level warning instruction is made to low liquid level signal and immediately, after liquid level goes back up to normal level 10min, elevator pump opens again
Dynamic and normal operation, until there is low liquid level warning instruction next time, carry out according to this；To avoid at EPT high concentrated organic wastewaters
Electrocatalytic oxidation equipment is managed because when outlet conduit blocks or the abnormal situation of other influences water outlet occurs, PLC will start high liquid
Position is protected to stop the work of elevator pump, avoids the occurrence of that waste water is excessive, high level does not set delay protection.Average mixer
Intermittence operation, intermittent time and run time are adjustable (according to setting is actually needed), flow through stain disease and electrolyte solution
Sequentially entered after fully mixing in electrode reaction room, the phegma circulatory system will be successive under PLC control system effect
Ground is then constantly in continuous running status to water homogenisation room supplement phegma, backflow fluid circulation is entered, only when phegma circulates
Complete equipment will also be automatically stopped operating while system ball float stops its operation when being in low liquid level, treat that water level returns to normally
Complete equipment recovers normal operation again after liquid level 10min.The reciprocating slag-water separation system under PLC control system effect
Intermittent start is run, and to realize pulp water separating action, its intermittent time and run time are adjustable.Aeration system exists
Continuity run state is realized under PLC controls, and aeration quantity size can be adjusted by the open degree of control valve.For electrode
For the partition type pole plate that reative cell is set, the compliance voltage level of PLC control system is 24V, and acquiescence current value is 500A, can hand
The input terminal voltage (0-36V) and electric current (0-1000A) of dynamic adjustment battery lead plate, with independent power supply voltage stabilizing rectifying installation, operation
Aspect, security, stability are higher.Finally, the electrocatalytic oxidation equipment will realize it under the control action of PLC control system
Automatic operating.
For whole system, when needing to operate a certain local devices, into after system, system is clicked on
Button, ends with system automatic running pattern are automatically stopped, then by clicking on system hand push button, mould is run manually into system
Formula, as needed, it can be controlled manually specific to each, it is only necessary to click on corresponding device start button into operation pages
It can be achieved.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
