A separation process of reverse osmosis water organics were concentrated

The present invention relates to a method of separating organics concentrated reverse osmosis water. The method comprising: reverse osmosis concentrated water was filtered through a glass fiber filter and then through a XAD-8 resin column, and ultrapure water to XAD-8 resin column, washing the mixture with water to obtain a mixed liquid effluent; hydrochloride backwash XAD -8 resin column to backwash water XAD-8 resin column, alkaline effluent hydrophobic organic component; mixing water with hydrochloric acid adjusted to a pH of 2, then the resin XAD-8 and XAD-4 resin column in series column, a hydrophilic organic water; sodium hydroxide backwash XAD-8 resin column, with pure water backwash XAD-8 resin column, the acidic effluent hydrophobic organic component; sodium hydroxide backwash XAD-4 resin column to backwash water XAD-4 resin column, the acidic water is weakly hydrophobic organic compounds; on XAD-8 resin was subjected to Soxhlet extraction with methanol and dried to give the extracts rotary evaporated to dryness, and then dissolved in water get neutral hydrophobic organics. The present invention provides separation methods may be effective reverse osmosis separation of organics concentrated water.
