Water is the world's most important natural resources , because there is no water there is no life . And a variety of other resources in the multiple uses of water can not find substitutes . As a reliable water supply is a prerequisite for the establishment of a permanent residential areas , water plays a vital role in urban development . Unfortunately, a city waste water and garbage are the main factors causing environmental pollution . Steps must be taken to properly handle wastewater , the establishment of a collection , transportation, treatment and use of sewage drainage engineering facilities no hierarchy of environmental protection , health, and economic aspects have a very important significance . In recent years, suspended solids filter ( SF ) ultrafiltration (UF) reverse osmosis ( RO ) the power desalination ( EDI ) the characteristics of membrane water treatment technology has been the domestic market is widely recognized and accepted , the current water treatment technology trends . The technology is mature and reliable, with excellent quality of water , low operating costs, high degree of automation and environmental benefits . In this thesis, a modern full- membrane water treatment technology combined with the existing drainage facilities on the basis of the power plant 's economic strength , technology management capabilities and future trends , according to the actual situation , local conditions life of gas turbine power plant in Daqing , industrial wastewater treatment , study efficient combination of membrane bio- filter device ( MBR ) reverse osmosis (RO) unit and two sets of automatic flotation device ultrafiltration device combination of reverse osmosis unit process to determine the selection of efficient membrane bio- filtration devices ( MBR ) reverse osmosis (RO) unit combination , removal of organic matter in wastewater , color, hardness , and most of the ions , to achieve the purpose of the gas turbine power plant sewage treatment .
