Abstract: Abstract:The working principle of the integrated membrane water treatment technology was introduced. The process flow and equipment arrangement of the integrated membrane water treatment technology were expounded. Taking Tianjin Huadian Wuqing Gas Fired Distributed Energy Station as example, the feasibility to use the integrated membrane water treatment technology to treat the circulating water blowdown water of the distributed energy station was analyzed. After the integrated membrane water treatment technology was put into use, the water was saved, and the pollutant emission was reduced. The ion exchange equipment of the traditional water treatment process was replaced, and the technical difficulty in waste water reuse was overcome.

Key words: Keywords:integrated membrane water treatment technology, ultra filtration membrane, reverse osmosis membrane, EDI membrane, circulating water blowdown water, desalination
