Abstract

The invention discloses a method of removing sulfonamide antibiotics in water by utilizing an ionization radiation technology, belonging to the technical field of nuclear technology application and environmental protection. The method can be used for effectively removing sulfonamide antibiotic drugs (for example sulfamethazine) in water without adjusting pH of wastewater and adding any chemical agent by applying the ionization radiation (high-power electron beams generated by electron accelerator or gamma rays generated by a radioactive source) technology. The method disclosed by the invention is simple, effective, easy to operate and can be used for treating antibiotic wastewater.

Description

Technical field

[0001] The invention belongs to the field of nuclear technology application and environmental protection technology, and specifically relates to a method for removing sulfonamide antibiotics in water by using ionizing radiation technology. Background technique

[0002] Antibiotics play an important role in human health, fishery and animal husbandry production. However, the unused, metabolic residues and the antibiotics discharged into the water environment during the production process, if not properly treated, will affect the environment and ecology after entering the water body. Sulfa drugs are a class of synthetic broad-spectrum antibiotics with a wide range of applications and large dosages. Among them, sulfamethazine is one of the most commonly used drugs. It stays in the water environment for a long time, and can be enriched in organisms through the food chain, causing microbial resistance and harming human health. Due to its non-degradability and easy mig...
