Verfahren zur Behandlung von Abwasser

摘要

The present invention relates to a method for treating waste water including the steps of: oxidizing the waste water, and then treating the oxidized waste water with a reverse osmosis membrane having high salt rejection rate. By being treated with the reverse osmosis membrane, the waste water is separated into a impermeated liquid which contains a oxidizable substance, and a permeated liquid which contains almost no oxidizable substance.
