The parameters of additional treatment of biologically pure antibiotic production sewage in winter were studied on a pilot model of a 3.72 m3 biopond with higher aquatic plants (Phragmites communis). Sufficiently high efficiency of the process of possible provision of the required sewage quality were shown. A mathematical model of the process based on the first order reaction equation was developed. Its application was estimated and the values of the equation constants were measured.
