Treatment method and water treatment method of non-ionic surfactant-containing water

摘要

Adsorption process of permeate | transmitting the water containing a nonionic surfactant as a feed water, permeate | transmitted through a microfiltration membrane or an ultrafiltration membrane, and reducing the density | concentration of a nonionic surfactant as treated water, an alkali agent, an anionic surfactant, and A method of treating nonionic surfactant-containing water having a desorption step of contacting at least one of the oxidizing agents with the microfiltration membrane or the ultrafiltration membrane to desorb the nonionic surfactant adsorbed on the filtration membrane. A water treatment method of treating this treated water with a permeation membrane.
