PROCESS FOR TREATING WASTEWATER ORIGINATING FROM THE PREPARATION OF A HALOGENATED POLYMER

摘要

Process for treating wastewater originating from the preparation of a halogenated polymer, which includes a step of polymerizing at least one halogenated monomer carried out in an aqueous medium, from which the unreacted monomer and the polymer obtained have then been separated, said process comprising: - a step of physicochemical treatment of at least one portion of said wastewater, at least one portion of which has previously undergone a first purification via at least one physical treatment; - a step of final purification, comprising a biochemical filtration carried out using a membrane bioreactor, of at least one portion of the water originating from the physicochemical treatment.
