The technology of local wastewater treatment from antibiotics is presented. It based on the consistent use of physico-chemical treatment methods and allows to remove antibiotics and related substances from wastewater to the requirements of regulations and divert treated wastewater into the municipal sewerage system. Model solutions of cefuroxime, a cephalosporin antibiotic, in distilled water with a concentration of 25 and 35 mg/dm3 were used for the study. Chemical oxygen demand model solutions, which is, respectively, 90 and 120 mg/dm3. The effect of reducing the chemical oxygen demand in coagulation and settling of wastewater in the case of the use of ferrous sulfate III was 79.2% and 75%, which is 4.2…6.7% higher than when using aluminum sulfate. The change of the chemical oxygen demand indicator of wastewater of the pharmaceutical enterprise according to the stages of their purification is established: "aeration – coagulation with ferrous sulfate III – settling – oxidation – filtration". After filtration, the effect of reducing the chemical oxygen demand was 95.8…100% at initial values of 120 and 90 mg/dm3, respectively. The technology of local wastewater treatment from antibiotics has been developed. It based on the consistent use of physico-chemical treatment methods and allows to remove antibiotics and related substances from wastewater to regulatory requirements and divert treated wastewater into the municipal sewerage system. The use of the developed technology of local wastewater treatment by antibiotics and related substances will lead to the requirements of industrial wastewater discharge into the municipal sewerage system, to significantly reduce the risk of antibiotics on the microorganisms of activated sludge biological treatment plants of the city, to reduce operating costs permissible discharges of wastewater into a natural reservoir.
