Example 3: the system for treating antibiotics in aquaculture sewage through photodegradation is basically the same as that in the embodiment 1, except that the included angle between the crawler-type grating and the bottom surface of the grating 6 is 30 degrees, and the aerator 12 is a jet aerator;
the culture pond is a fresh water culture pond, five sampling points are distributed in the region of the fresh water culture pond, 2L of each water sample at the surface layer and 0.5m below the water surface is taken at each sampling point, the water samples are filtered by a 0.45-micrometer filter membrane, the pH value is adjusted to 2 by HCl, tetrasodium ethylene diamine tetraacetic acid (EDTA-4 Na) and an internal standard substance are added, extraction and purification are carried out, then the volume is fixed to 1mL by rotary evaporation and nitrogen blowing, and high performance liquid chromatography-mass spectrometry (HPLC-MS) is adopted for detection and averaging. The sulfadiazine concentration in the water sample is calculated to be 29.3ng L-1The oxytetracycline concentration was 35.9ng L-1Chloramphenicol concentration 22.6ng L-1And the COD was found to be 565 mg/L;
the method for treating the antibiotics in the aquaculture sewage by photodegradation by using the system for treating the antibiotics in the aquaculture sewage by photodegradation comprises the following specific steps:
(1) the filter screen at the water outlet of the culture pond prevents aquatic products from entering the drainage pipeline, the culture sewage in the culture pond enters the grids through the drainage pipeline, and particulate matters and suspended matters in the culture sewage are blocked by the grids among the grids and are conveyed to enter the waste residue collection bin for collection;
(2) conveying the aquaculture sewage into a purification tank through a water pump and a drainage pipeline, carrying out a photodegradation reaction on antibiotics in the aquaculture sewage for 5-20 h under the irradiation of an ultraviolet lamp on the wall of the purification tank, and introducing oxygen into an aerator at the bottom of the purification tank to accelerate the photodegradation reaction of the antibiotics and enhance the photooxidation effect to remove chemical oxygen demand;
(3) the purified water in the purification tank returns to the culture tank through the water distribution pipeline, the online water quality analyzer of the water distribution pipeline analyzes the water quality of the water distribution pipeline, the water quality does not reach the standard of the culture water, and the flow valve of the water distribution pipeline is adjusted to reduce the water outlet flow so as to prolong the sewage purification time in the purification tank until the water quality reaches the standard.
The results of the tests on the treatment time of 10 hours and 20 hours for the waste water in the clean water reservoir of this example are shown in Table 2,
TABLE 2
As can be seen from Table 2, when the sewage treatment time in the water purification tank is 20 hours, the removal rate of sulfadiazine is 95.7%, the removal rate of terramycin is 92.3%, the removal rate of chloramphenicol is 93.6%, and the removal rate of COD is 80.2%;
from the embodiment 2 and the removal rate of antibiotics in aquaculture sewage in the embodiment, the method for treating antibiotics in aquaculture sewage through photodegradation has extremely high removal capacity on antibiotic pollutants in aquaculture water, the removal rate of antibiotics (sulfadiazine, oxytetracycline and chloramphenicol) can reach over 90% when the sewage stays in the circulating pond for 20 hours, the antibiotic in aquaculture sewage can be efficiently removed, the removal efficiency on indexes such as SS and COD is good, no external source is added, and the method is economical, environment-friendly and sustainable.
While the present invention has been described in detail with reference to the specific embodiments, the present invention is not limited to the embodiments described above, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art.
