Description

The ultrasonic electrochemical wastewater treatment equipment
Technical field:
The utility model belongs to the electrochemistry technical field of waste water processing, particularly a kind of device of handling toxic organic pollutant waste water with ultrasonic electrochemical method.
Background technology:
The trade effluent that the waste water that contains poisonous organic pollutant is bio-refractory, harm is big.Aromatic pollution is the important source of toxic organic pollutant because characteristics such as its Stability Analysis of Structures, toxicity are big, difficult degradation extensively are present in the trade effluents such as printing and dyeing, chemical industry, pharmacy, oil refining, coking.Dyeing waste water is one of waste water that contains aromatic pollution, because of characteristics such as its organic pollutant content height, colourity are dark, contaminant component difference is big, becomes the difficult trade effluent of generally acknowledging both at home and abroad.Method of wastewater treatment relatively more commonly used at present mainly contains physics method, chemical method, biological process etc., and wherein electrochemical method is a kind of effective ways of handling difficult degradation toxic organic pollutant in the waste water, has become the competitive method of wastewater treatment of a class.
The ultimate principle that electrochemical method is handled waste water is to make pollutent that the Direct Electrochemistry reaction take place on electrode or the strong oxidizing property active specy that utilizes electrode surface to produce makes pollutent generation redox transformation, finally make the macromole hardly degraded organic substance oxidative degradation in the water body become low toxicity or nontoxic small-molecule substance, even directly be degraded into CO 2And H 2O is near permineralization.
With regard to electrochemistry, be that the anode-catalyzed oxidation of electrolytic flocculation or electrochemistry all exists degradation effect place not fully up to expectations,
The utility model content:
The purpose of this utility model is to provide a kind of novel toxic organic pollutant wastewater treatment equipment-ultrasonic electrochemical wastewater treatment equipment, this device integrates titanium anodic oxidation, hydroxyl free radical oxidation, ultrasonic cavitation, electricity and flocculates, good degrading effect has realized the degraded to toxic organic pollutant.
The utility model is achieved through the following technical solutions:
A kind of ultrasonic electrochemical wastewater treatment equipment comprises housing 12, power supply 11, ultrasonic generator 9 is provided with aerator 6 from bottom to top in housing 12 inside, water distributor 5, POROUS TITANIUM anode 4 parallel to each other, Porous Stainless Steel negative electrode 3, porous iron anode 2, ultrasonic probe 10; Be connected with inlet pipe 7 on the housing 12 bottom aerators 6, be connected with water inlet pipe 8 on the water distributor 5, housing 12 tops are provided with rising pipe 1, ultrasonic probe 10 is connected with the ultrasonic generator 9 that is arranged on housing 12 outsides by lead, POROUS TITANIUM anode 4 and porous iron anode 2 and 11 anodal linking to each other of power supply, stainless steel cathode 3 links to each other with power supply 11 negative poles.
Further, described Porous Stainless Steel negative electrode 3 powers on and deposits the Zn-Se film.
Principle of work of the present utility model is such: at first, organism by preliminary oxidative degradation, has the partial oxygen air elutriation to go out (analysing oxygen under single anodic situation is that side reaction reduces current efficiency) at the first anode (POROUS TITANIUM electrode) simultaneously.
Organism-ne (first anode) → degraded product
2H 2O-4e (first anode) → O 2+ 4H +
The stainless steel cathode of oxygen on first anode top that oxygen that the first anode is separated out and aeration produce is reduced to hydrogen peroxide (anode is analysed oxygen and obtained utilizing), near the ferrous iron that is produced the second anode (porous iron anode) of hydrogen peroxide on negative electrode that produces is reduced to hydroxyl free radical, and (Fenton reagent react, body series do not need to add Fe 2+And H 2O 2)
Negative electrode: O 2+ 2H ++ 2e → H 2O 2
Second anode (porous iron anode): Fe-2e → Fe 2+
In the solution: H 2O 2+ Fe 2+→ Fe 3++ OH+OH -
Hydroxyl free radical has very strong oxidation activity, and majority of organic pollutants is had oxygenizement, as if cathode hydrogen evolution, just hindered the carrying out of cathodic reaction, thereby the OH generating capacity reduces significantly in the system.Stoped cathode hydrogen evolution behind the Porous Stainless Steel cathode electrodeposition Zn-Se film, thereby cathodic reaction is carried out smoothly.
OH+ organism → degraded product
Fe 3++3OH -→Fe(OH) 3
Fe (OH) 3Adsorb organic compound removes by filter.
The phonochemical reaction of ultrasonic wave in water mainly comprises following reaction:
H 2O→·H+·OH
·H+·OH→H 2O
2·H→H 2
·OH+·OH→H 2O 2
OH+ organism → oxidation products
The beneficial effects of the utility model are: the utility model has adopted double anode, and promptly POROUS TITANIUM anode and porous iron anode make anode analyse oxygen and obtain utilizing; Stoped cathode hydrogen evolution behind the galvanic deposit Zn-Se film on the Porous Stainless Steel negative electrode, accelerated hydroxyl free radical, improved degradation efficiency organic oxidation rate; Mass transfer is strengthened under the ultrasonic wave effect simultaneously, and ultrasonic cavitation produces localized hyperthermia can reach 5000 ℃, and pressure can reach 50MPa, can strengthen hydroxyl free radical so greatly to organic oxidation rate, improves degradation efficiency, the cotton-shaped Fe (OH) that produces in the system 3The absorbed portion organism settles down, and can remove by filter.
