Description
Technical Field
The utility model relates to the field of sewage treatment, in particular to a purification device based on enrichment, oxidization and degradation of trace antibiotics in sewage.
Background
Antibiotics have become one of the most widely used drugs as one of the most important medical findings in the 20 th century. Antibiotics can inhibit or kill bacteria, and at the same time, they are also added to the feed of healthy animals for a long period of time for preventing diseases and promoting animal growth. The amount of antibiotic used in the world was statistically up to 65% increased over a period of approximately 15 years. Antibiotics are only partially metabolized in animals and humans, and the non-metabolized fraction is excreted into the ecosystem by feces and urine. Antibiotics are often detected in drinking water, surface water, and sewage because they are mostly water-soluble. The environmental concentration of antibiotics is generally ng/L-mug/L, and the long-term low concentration of antibiotics in the environment is one of the main factors for inducing the bacteria in the environment to generate drug resistance. At the same time, antibiotic residues create a potential hazard to human and animal health through food chain enrichment. As a new type of environmental pollutants, the removal of antibiotics has become a global environmental pollution problem, and conventional sewage and drinking water treatment processes cannot effectively remove antibiotics, which puts a new demand on efficient treatment technologies of antibiotics.
The antibiotic treatment method in the environment is various and mainly comprises an adsorption method, a high-grade oxidation method, a biological method and the like. The adsorption method has the advantages of low cost, high efficiency and ecological environment protection. Thousands of potential adsorbents have been developed so far, and as adsorbents with strong adsorption capacity, stable properties and high recycling rate are continuously pushed out, adsorption technology is mature, but adsorption technology can only entrap antibiotics but cannot effectively degrade antibiotics.
The advanced oxidation method mainly utilizes an oxidant to generate various free radical oxidative degradation pollutants, for example, the ozone oxidation method and the photo/electrochemical oxidation method can efficiently treat micro pollutants in water under certain set conditions. However, the advanced oxidation technology often needs to add chemicals such as an oxidant, and the like, so that potential secondary pollution is caused, and practical application is limited.
The biological method utilizes the microorganism to naturally degrade the antibiotics in the environment, mainly comprises an aerobic biological method, an anaerobic biological method and the like, and has the advantages of economy, environmental protection, low energy consumption and the like, but the activity of the microorganism has higher requirement on environmental toxicity, and the antibiotics can cause the inactivation of the microorganism and even induce the generation of resistance genes.
