Description

technical field [0001] The invention belongs to the technical field of antibiotic treatment in water, and relates to a filter type electrochemical reactor and a method for removing antibiotics in water. Background technique [0002] With the development of cities and the increase of human activities, industrial by-products or pollutants, such as chemicals, dyes, drugs, pesticides and other organic pollutants, enter the water body, which makes the problem of water pollution increasingly serious and has attracted widespread attention. Antibiotics are the chemicals with the largest amount of use and the closest relationship with organisms. They can not only control diseases, but also prevent animal and plant diseases. They have the characteristics of wide application range, large amount of use, and high frequency. However, most antibiotic drugs can hardly be completely metabolized by organisms, and the antibiotic metabolites excreted from the body are still active after testing...
