Abstract: Abstract:Taking the polyurea anticorrosion coating of water tank in water treatment system as example, the polyurea anticorrosion technology and the pollution of the polyurea on the reverse osmosis membrane were introduced. Combining with actual case of membrane method water treatment project, the related problems needing attention in polyurea anticorrosion construction were put forward. The result in this paper is useful for decreasing the pollution of the polyurea on the membrane system.
