Problems solved by technology

A large amount of wastewater containing antibiotics is discharged into the environment, making it difficult for general microorganisms to grow and effectively degrade antibiotics
While polluting the water environment, these wastewaters also seriously endanger human health.
[0003] CN110526418B discloses a method for degrading antibiotics in aquaculture wastewater by using immobilized dense porosity bacteria, which is in the acidic range (pH3.0-6.0), whether it is under the extremely low temperature condition of 0°C or the high temperature condition of 70°C Laccase (Lac-Q) can efficiently degrade tetracyclic and sulfonamide antibiotics, but due to the high COD and variety of antibiotics in aquaculture wastewater, this method cannot fully degrade the antibiotics in aquaculture wastewater
[0004] CN108002605B discloses a method for treating antibiotics in seawater aquaculture wastewater. Ferrate ions are produced by electrolytic reaction, and then combined with sodium hypochlorite produced in the system by insoluble anode graphite electrodes to effectively promote it, it can treat antibiotics in aquaculture wastewater. However, due to the large amount of marine aquaculture wastewater, this method has the problems of high energy consumption, low treatment efficiency, and difficulty in comprehensive treatment, which makes this method not suitable for large-scale use

Embodiment 1

[0040] This embodiment handles the production wastewater from a livestock and poultry breeding factory:

[0041] After testing: COD8450mg / L, norfloxacin 43.2μg / L and azithromycin 11.8μg / L;

[0042] The aquaculture wastewater is transported to the acidification pond for acidification treatment. The acidification pond adopts an anaerobic hydrolysis acidification process. The hydraulic retention time of the acidification pond is 8h, pH5.5, DO is 0.15-0.2mg / L, and norfloxacin in the effluent 24.2 μg / L and azithromycin 2.8 μg / L, the effluent of the acidification pool is transported to the alkalization pool, the alkalization pool is provided with an alkali box, and the pH of the wastewater in the alkalization pool is adjusted to 9 and left for 2 hours; The supernatant in the chemical tank is transported to the cathode chamber A, the anode chamber A of the electroporation anion cell is connected to the concentrate pool, the voltage between the anode A and the cathode A is controlled ...

Embodiment 2

[0045] On the basis of Example 1, a biochemical pool is set: the wastewater in the cathode chamber A and the wastewater in the anode chamber B go to the biochemical pool, and the biochemical pools are anaerobic pools (DO is 0.2mg / L, residence time 36h) and Aerobic pool (DO 3.5mg / L, residence time 8h), effluent COD 32mg / L, norfloxacin 0.01μg / L, azithromycin concentration 0.05μg / L. It meets the first-level standard of "Discharge Standard of Pollutants for Livestock and Poultry Breeding Industry" (GB18596-2001) and the first-level standard of "Integrated Wastewater Discharge Standard" (GB8978-1996).

Embodiment 3

[0047] On the basis of embodiment 1, the advanced oxidation tank is set: the wastewater in the anode chamber A and the cathode chamber B are sent to the advanced oxidation tank, and the ozone catalytic mode is used to carry out oxidation treatment, and the norfloxacin concentration after treatment is 12.1 μg / L, the concentration of azithromycin is 6.5 μg / L.

Abstract

The invention relates to a concentration system and a treatment system for antibiotic-containing breeding wastewater. The concentration system comprises an acidification tank, an alkalization tank, an electric anion removal tank, a concentrated solution tank, a sludge tank, a cracking tank, an ultrasonic pressure filter tank and an electric cation removal tank. The breeding wastewater is conveyed to the acidification tank for acidification treatment, and the acidification tank adopts an anaerobic hydrolysis acidification process. The effluent of the acidification tank is conveyed to the alkalization tank, and the wastewater in the alkalization tank is conveyed to an anode chamber A of the electric anion removal tank. After sludge in the sludge tank passes through the disintegration tank and the ultrasonic pressure filter tank, the wastewater is conveyed into a cathode chamber B of the electric cation removal tank to realize antibiotic concentration, the concentrated wastewater is subjected to oxidation treatment through a super oxidation tank, and the other part of wastewater is treated through a biochemical tank. According to the concentration system for antibiotic-containing breeding wastewater, the solubility of antibiotic molecules in the wastewater is improved.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, and in particular relates to a concentration system for antibiotic-containing breeding wastewater and a treatment system thereof. Background technique [0002] With the continuous development of the breeding industry, in order to prevent diseases and promote the growth of poultry in the breeding process, a large number of antibiotics are used as feed additives or drinks, followed by a large number of uninfected animals and / or The antibiotics used by plants and the discharge of untreated antibiotics into the environment will bring great troubles to people. A large amount of wastewater containing antibiotics is discharged into the environment, making it difficult for general microorganisms to grow and effectively degrade antibiotics. While polluting the water environment, these wastewaters also seriously endanger human health. [0003] CN110526418B discloses a method for degrading antibiotics ...
