    水污染控制与治理科技重大专项(2010ZX07212-008)

Abstract:

Polyelectrolyte-enhanced ultrafiltration (PEUF)is a newly emerged method for water treatment that can effectively remove various low-concentration pollutants from wastewater,having pretty good developing prospect.The mechanism of PEUF,types of polyelectrolyte and factors affecting the removing efficiency are introduced in detail.The recovery and reuse of polyelectrolyte are summarized,including ultrafiltration with acid,ultrafiltration with salt,electrolysis recovery and the combination between one another of the three methods mentioned above.The problems existing in this technology and the future research trend are also put forward.

Key words: polyelectrolyte, ultrafiltration, organic pollutants, anions, metal ions
