Abstract

A treatment method for erythromycin thiocyanate extraction waste water is disclosed. The method includes a) feeding the extraction waste water to a first membrane filtration system to obtain a first concentrated liquid and a first clear liquid; b) feeding the first concentrated liquid into a second membrane filtration system to obtain a second clear liquid; and c) combining and reusing the first clear liquid and the second clear liquid, and feeding a second concentrated liquid into a biochemical treatment system, wherein the first membrane filtration system ensures that the membrane flux of the extraction waste water under an operating pressure of 12-15 bar is 14-16 lmh and that the recovery rate is 55-60%; and the second membrane filtration system ensures that the membrane flux of the first concentrated liquid under an operating pressure of 26-30 bar is 17-20 lmh and that the recovery rate is 55-60%. A treatment device used for the method is also disclosed. Through the method and the device, ideal treatment effects on the extraction waste water can be achieved, and device blockage in a treatment process does not occur.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a wastewater treatment method and equipment for extracting erythromycin thiocyanate. Background technique [0002] In the production process of erythromycin thiocyanate, a large amount of waste water will be produced. The main sources of waste water are fermentation waste water, extraction waste water, solvent recovery waste water, filter press waste water of bacteria residue, cleaning equipment, still residue, flushing filter cloth and bottom waste water. . Wherein the extraction wastewater is a large amount of high-salinity refractory wastewater containing pollutants produced during the extraction and purification process of erythromycin thiocyanate. The wastewater has the following characteristics: high organic load; high NH3-N content; high SCN _ ; High COD; there are biological inhibitory substances, such as residual organic solvents, surface activ...
