Abstract: This paper analyzes the existing problems in water affairs management in 91 thermal power enterprises, and discusses the technical route of the water resources utilization and pollution prevention based on the current policies. The technical route is implemented in two steps. The first step is to optimize the water use of the whole plant by realizing the cascade utilization, the quality treatment and the reuse of water resources, and to minimize the wastewater of high salinity as well; the second step is the comprehensive treatment and transformation of the high salt wastewater, which cannot be reused, consumed and discharged, into the integrated wastewater treatment system. The waste water recycling can be realized through pretreatment softening, concentration reduction, evaporation desalination and solid waste disposal. It provides reference for the thermal power enterprises to explore the pollution prevention and comprehensive utilization of water resources.

Key words: water pollution prevention, comprehensive control, thermal power plant, technical route, cascade utilization
