NOVELTY - A radioactive strontium-containing wastewater processing method involves adding 1000-2000mg/L sodium carbonate into a reactor, stirring the mixture. Strontium ions in radioactive waste water and the sodium carbonate are stirred to form large-sized particles and precipitated to bottom of the reactor. Radioactive waste water is taken into membrane separator, followed by adding ferric + iron salt 3.0mg/L by aeration stirring to generate particulate matter. The radioactive waste water is separated by reverse osmosis using an oxidized graphene composite membrane. USE - Method for processing radioactive strontium-containing wastewater. DETAILED DESCRIPTION - A radioactive strontium-containing wastewater processing method involves adding 1000-2000mg/L sodium carbonate into reactor, and stirring the mixture. Strontium ions in radioactive waste water and the sodium carbonate are stirred to form large-sized particles and precipitated to bottom of the reactor. Radioactive waste water is taken into membrane separator, followed by adding ferric + iron salt 3.0mg/L by aeration stirring to generate particulate matter. The radioactive waste water is separated by reverse osmosis using an oxidized graphene composite membrane, where the oxidized graphene composite membrane is prepared by oxidizing graphene compound polydopamine on a silane coupling agent pre-modified sheet-like porous carrier and thickness of the two-dimensional water channel is less than 0.45nm.
