Problems solved by technology

[0007] In order to solve the above-mentioned due to the increasing scale of aquaculture, the discharge of seawater aquaculture wastewater has become an important way for antibiotics to enter the environment, and can lead to a series of environmental problems such as enhanced drug resistance of pathogenic microorganisms, inhibition of beneficial microbial activity, and antibiotic residues in seafood. The invention provides a method for treating antibiotics in seawater aquaculture wastewater, which is used to remove a large amount of oxytetracycline, sulfamethoxazole, virginiamycin, chloramphenicol and other substances that are difficult to effectively treat in the aquaculture wastewater

Abstract

The invention relates to the treatment of antibiotics in mariculture wastewater with simple operation and used for removing a large amount of oxytetracycline, sulfamethoxazole, virginiamycin and chloramphenicol, etc. The method solves a series of environmental problems such as the increasing scale of aquaculture, the discharge of seawater aquaculture wastewater has become an important way for antibiotics to enter the environment, and can lead to enhanced drug resistance of pathogenic microorganisms, inhibition of beneficial microbial activity, and antibiotic residues in seafood , has an excellent effect of purifying water quality, and the treatment cost is low, and no harmful substances are produced during the treatment process.

Description

technical field [0001] The present invention relates to a water treatment method, in particular to a simple operation, which is used to remove a large amount of oxytetracycline, sulfamethoxazole, virginiamycin and chloramphenicol contained in aquaculture wastewater, which are difficult to treat effectively Treatment of antibiotics in marine aquaculture wastewater. Background technique [0002] Mariculture is a production method that uses shallow seas, tidal flats, harbors, ponds and other sea areas to raise and reproduce marine economic animals and plants. It is one of the important ways for human beings to use marine biological resources and develop marine aquaculture. [0003] In recent years, my country's mariculture has developed rapidly, especially the development of main economic species such as kelp, laver, mussels and prawns, which has driven the development of coastal economy and has become a major industry in coastal areas. Kelp farming ranks first in the world in...
