Problems solved by technology

After anodic oxidation generates iron ions, the anode is consumed. On the one hand, the anode plate needs to be replaced continuously during the treatment process, which is costly and requires shutdown during replacement, which affects upstream production and cannot form continuous processing; The iron ions will flow out with the sewage and cannot be used continuously. It is necessary to continuously consume the anode to generate iron ions, which is not conducive to recycling and increases costs, and the iron sludge will precipitate in the sewage after the sewage flows out and form secondary pollution, which increases treatment. cost

preparation example Construction

[0055] The preparation method of PANI / Ti anode is:

[0056] S01: The porous titanium mesh polished with sandpaper was washed with NaOH solution at 95°C for 1 hour, acid-washed with HCl solution at 90°C for 1 hour, rinsed with deionized water, and then dried in a blast drying oven at 105°C spare.

[0057] S02: Mix 0.06 parts of sodium dodecylsulfonate, 0.12 parts of n-butanol, and 10 parts of a mixture of butyl acrylate and ethanol (the weight ratio of butyl acrylate and ethanol is 1:1, that is, each of butyl acrylate and ethanol 5 parts), was added to 30 parts of deionized water and magnetically stirred until it was in the form of a transparent microemulsion, the pH value was adjusted to 1 with hydrochloric acid, and 3 parts of aniline monomer was added dropwise to obtain a uniform solution.

[0058] S03: Under nitrogen and ice-water bath conditions, slowly add 10 parts of ammonium persulfate solution dropwise to the homogeneous solution obtained in the above step S02, and th...

Embodiment 2

[0062] The difference between this embodiment and the described embodiment is that in this embodiment, pyrite roasted slag-based Co / Fe 0 The preparation method of particle electrode 12 is:

[0063] Fully soak and clean the pyrite roasted slag, dry it at 110°C for 6 hours, cool to room temperature, put it in a ball mill and grind it into powder, and use an 80-mesh screen to sieve the pyrite roasted slag powder; Accurately weigh parts by weight: 55 parts of pyrite roasting slag powder, 12 parts of sodium chloride, 15 parts of cement, Co, Fe 0 20 parts of active components, mixed well, rolled into balls, and then placed in a constant temperature incubator at 35°C for 8 days to obtain stable pyrite roasting slag powder-based Co / Fe 0 Particle electrode 12 .

Embodiment 3

[0065] The difference between the present embodiment and the described embodiment is that in the present embodiment, pyrite roasted slag powder base Co / Fe 0 The preparation method of particle electrode 12 is:

[0066] Fully soak and wash the pyrite roasted slag powder, dry at 115°C for 3 hours, cool to room temperature, put it in a ball mill and grind it into powder, and use an 80-mesh screen to sieve the pyrite roasted slag powder Powder; Accurately weigh parts by weight: 65 parts of pyrite roasting slag powder, 8 parts of sodium chloride, 25 parts of cement, Co, Fe 0 15 parts of active components, mixed thoroughly, rolled into balls, and then placed in a constant temperature incubator at 30°C for 10 days to obtain stable pyrite roasting slag powder-based Co / Fe 0 Particle electrode 12 .

[0067] In other embodiments of the present invention, the device of the water treatment system can also be of other structures, for example, the reactor is arranged as a cuboid structure, ...

Abstract

The invention provides a three dimensional-similar electro-Fenton water treatment system and a method used for degrading carbostyril antibiotics. The three dimensional-similar electro-Fenton water treatment system comprises a reactor; the reactor comprises a three dimensional-similar electro-Fenton reaction zone and a biological filter material reaction zone; iron pyrite roasting slag based Co / Fe<0> particle electrodes are arranged at the three dimensional-similar electro-Fenton reaction zone; a biological filtering material is introduced into the biological filter material reaction zone; wastewater is subjected to common treatment by microorganisms on the biological filtering material so as to reduced COD and ammonia nitrogen to a certain degree, and then is delivered into the three dimensional-similar electro-Fenton reaction zone for deep treatment of substances difficult to be biodegraded; a persulfate is introduced into the reactor using an agent adding device, wastewater is delivered into the reactor, and is mixed with the persulfate. Under the action of particle electrode-loaded Fe<0> at the three dimensional-similar electro-Fenton reaction zone, the persulfate is activated so as to generate sulfate free radicals, hydroxyl free radicals are generated via electrocatalysis, and the sulfate free radicals and the hydroxyl free radicals are used for degrading pollutants in waste effectively.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water treatment system and method for treating sewage containing quinolone antibiotics for three-dimensional-electro-Fenton-like degradation of quinolone antibiotics. Background technique [0002] Quinolones antibiotics are synthetic antibacterial drugs containing 4-quinolone basic structure, which are widely used in pharmaceuticals and personal care products. These drugs have a bactericidal effect on a variety of Gram-negative bacteria and are used for genitourinary system diseases and gastrointestinal diseases. , and the treatment of Gram-negative bacterial infections of the respiratory tract and skin tissues. Quinolones antibiotics are discharged into the water body in the form of drug prototypes and metabolites, becoming trace persistent pollutants. The traditional activated sludge method has no obvious effect on the degradation of such pollutants. The sludge for wa...
