Background technology
PPCP (pharmaceuticals and personal care products) is medicine and personal-care supplies,
It is a kind of dirt including the chemical article such as prescription class and OTC class pharmaceuticals, sun-screening agent, cleaning agent, bactericide and spices
The general name of thing is contaminated, salicylic acid (SA) is class I non-steroid anti-inflammatory and antalgic class medicine in PPCPs pollutants, has sterilization, anti-inflammatory
Deng effect, clinical and everyday skincare largely uses, and is widely present with trace concentration, the equal energy in surface water, underground water, soil
Detect, can be dirty with high water soluble, persistence, bioaccumulation (some is with fat-soluble), the characteristic of long-distance migration
Drinking water is contaminated, has bio-toxicity to organism.At present, the salicylic method handled in sewage has bioanalysis, membrane technology
With coagulation technology etc., but these methods are all undesirable to SA removal effect.
Strong oxdiative active material has strong oxidation to larger molecular organicses caused by advanced oxidation processes, is advantageous to handle
Salicylic acid in sewage, and three-diemsnional electrode is a kind of new advanced oxidization method, its three-dimensional-class electro-Fenton reaction region is no longer
It is confined on the simple geometry surface of electrode, but is carried out on the three dimensions surface of whole bed, is had in recent years more
Research.Patent CN 102070230A disclose the method and device that a kind of three-diemsnional electrode electricity Fenton removes Organic substance in water, described
Device include reative cell and air chamber, carbon material negative electrode, iron plate anode and fixed bed three dimensional particles electrode, carbon are set in reative cell
Material cathode and iron plate anode connect the two poles of the earth of power supply respectively, and after energization, anodic oxidation generation iron ion, cathode surface generated
Hydrogen oxide, iron ion and hydrogen peroxide form the organic matter in electric Fenton reagent oxidation removal waste water.Anodic oxidation generate iron from
After son, anode is consumed, on the one hand, makes to need in processing procedure constantly to change positive plate, cost is higher, needs during replacing to stop
Work, influence process upstream operation, it is impossible to form continuous processing；On the other hand, the iron ion generated after anode consumption can be with dirt
