Method of using modified enteromorpha charcoal to remove antibiotics in aquaculture water

Abstract

The invention discloses a method of using modified enteromorpha charcoal to remove antibiotics in aquaculture water. The size of modified enteromorpha is 0.08 to 0.15 mm, the specific surface area is3214 m2 / g, and the total pore volume is 1.302 cm3 / g. The modified enteromorpha charcoal can be used to remove antibiotics in aquaculture water, is capable of being regenerated, and can be used to adsorb antibiotic pollutants for many times. The coal resource is saved, and the cost is largely reduced. As the concentration of modified enteromorpha charcoal increases, the contents of ciprofloxacin, norfloxacin, sulfafurazole, and roxithromycin in aquaculture water decrease continuously. When the concentration of modified enteromorpha charcoal reaches 25 g / L, the contents of ciprofloxacin and roxithromycin in aquaculture water become stable; when the concentration of modified enteromorpha charcoal reaches 30 g / L, the contents of norfloxacin and sulfafurazole in aquaculture water become stable;the contents of antibiotics barely change, even if the concentration of modified enteromorpha charcoal increases, and the removal rate is in a range of 32-51%.

Description

technical field [0001] The invention belongs to the technical field of water restoration and environmental treatment, and in particular relates to a method for removing antibiotics in aquaculture water by modified Enteromorpha charcoal. Background technique [0002] Antibiotics are microbial secondary metabolites that can selectively inhibit certain biological life activities at low concentrations, and their chemical semi-synthetic or fully synthetic derivatives. important drug for disease. Antibiotics not only have antibacterial effects, but also include antitumor, antiviral, immune suppression, insecticidal, and herbicidal effects. When fertilizers are applied to fields, the antibiotics in the fertilizers can contaminate the soil, and along with runoff and leaching, the antibiotics in the soil can enter groundwater and surface water. [0003] Similarly, human medical antibiotics are excreted into the environment through urine and feces, enter the sewer system, and flow i...

AI Technical Summary

Problems solved by technology

[0005] Traditional methods may have problems such as low treatment efficiency and high operating costs. It is necessary to develop a simple, efficient and low-cost method for removing antibiotics from sewage. The existing activated carbon has high cost and unsatisfactory regeneration effect. At the same time, the process is complicated, which is not conducive to Large-scale promotion and use
