Abstract

The invention relates to a process for recovering streptomycin sulphate from waste water by coupling foam separation and ion exchange, belonging to the technical field of waste water treatment. The process mainly comprises the following steps of: pretreating streptomycin sulphate waste water; adjusting the pH value of the streptomycin sulphate waste water to 5.5-7.5; adding lauryl sodium sulfate anionic surfactant into the pretreated streptomycin sulphate waste water, and extracting streptomycin sulphate by using a foam separation method; purifying the streptomycin sulphate through ion exchange; performing ion exchange by using a table concentrator, absorbing streptomycin sulphate in a foam liquid by using resin, and desorbing with sulfuric acid to obtain the streptomycin sulphate product. The process overcomes the defects of high cost, great operation difficulty, easy production of secondary pollution and unstable effect of the membrane separation process and can be used for effectively recovering streptomycin sulphate in waste water, and the recovery rate is high; the process has the advantages of simple and convenient technology, unique principle, convenient operation, low cost, no toxin, no pollution, wide application range and obvious economical and social benefits.

Description

technical field [0001] The technical scheme of the present invention belongs to the technical field of wastewater treatment, in particular to the process of recovering streptomycin sulfate in wastewater by coupling foam separation and ion exchange. Background technique [0002] Streptomycin sulfate is an aminoglycoside antibiotic that has a strong antibacterial effect on Mycobacterium tuberculosis. my country is a big country that produces streptomycin. The production wastewater has a large discharge volume, complex components, and contains a small amount of streptomycin. On the one hand, it causes product loss, and on the other hand, it affects the bacterial activity of wastewater treated by biochemical methods, making wastewater treatment difficult. . [0003] At present, the process of recovering antibiotics from production wastewater is mainly nanofiltration membrane method. The dissertation of Beijing University of Technology in 2000, "Study on the Separation and Recov...
