FIELD: recycling.
SUBSTANCE: invention relates to a method of processing and recycling of waste waters formed from production of polyvinyl chloride. Method of processing and recycling of waste waters formed from production of polyvinyl chloride includes the step of polymerizing at least one monomer containing vinyl chloride in an aqueous medium, then the unreacted monomer and the obtained polymer are separated from each other; herewith said method includes the steps of: evaporating at least one part of the above said waste waters in order to obtain purified, evaporated waste waters; condensing the purified, evaporated waste waters to obtain purified, condensed waste waters; repeatedly using the purified, condensed waste waters.
EFFECT: invention provides processing and recycling of waste waters formed from production of polyvinyl chloride at considerable reduction of pure water consumption required for production without excessive energy consumption.
