Problems solved by technology

Since spiramycin is not currently controlled as a water quality indicator, there are few special treatment links for spiramycin in the water treatment process, which also causes high residues of spiramycin in the treated wastewater, resulting in the discharge of spiramycin Into the water body, the pollution to the water body and the resulting environmental effects are becoming more and more serious, which has seriously threatened human health, and the existing removal methods (such as: physical method, chemical method, physical chemical method, etc.) In many cases, it is difficult to remove spiramycin from water

Abstract

The invention relates to a method for removing spiramycin in water in a nanofiltration mode. By means of the characteristic that the nanofiltration membrane separation technique can be used for effectively removing 200-1000 organics, the method for removing the spiramycin in water in a nanofiltration mode can well retain spiramycin with more than 800 molecular weight in water. According to the method for removing the spiramycin in water in a nanofiltration mode, spiramycin solutions with different concentrations are treated as research objects, different nanofiltration membranes are selected, the operating pressure and the operation temperature are changed, a nanofiltration separation performance test is carried out, and the research on the removal of the spiramycin is investigated. The method for removing the spiramycin in water in a nanofiltration mode provides a feasible control technology for effectively removing the spiramycin in water, and has wide application prospects.

Description

technical field [0001] The invention relates to a method for removing spiramycin in water by nanofiltration, belonging to the technical field of water treatment. Background technique [0002] Spiramycin (spiramycin) is a macrolide antibiotic, and its structure has optical rotation and characteristic ultraviolet absorption. It is an organic substance that is produced by organisms (including animals, plants and microorganisms) during their life activities or obtained by other methods, and can selectively inhibit or affect other biological functions at low concentrations. Its molecular weight is 843.06. It is mainly used clinically for infections caused by Gram-positive bacteria, some Gram-negative bacteria, Rickettsia, and large viruses. The annual output in my country has exceeded 2,000 tons. Since spiramycin is not currently controlled as a water quality indicator, there are few special treatment links for spiramycin in the water treatment process, which also causes high re...
