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.
