The Provisional Regulations on the Management of Emission Permits issued by the Ministry of Environmental Protection stipulates that the power plants must get a permit of discharging pollutants from July 1 st

2017. According the investigation of a thermal power plant subordinate to a large-scale power generation group company

the wastewater discharge of some power plants don't meet the requirements of the discharge permit system. To solve the existing problems

the study proposes the fundamental principle of formulating the technical route for water conservation and wastewater treatment in thermal power plants. The technical route should carry out on the basis of the assessment of water usage

and be divided into the administration of water conservation

wastewater reuse

monitoring system improvement and high-salt wastewater treatment. In addition

the key factors of water conservation and wastewater treatment are discussed according to the transformation examples of two power plants. Finally

the technical route for water conservation and wastewater treatment in an example thermal power plant is given

and related suggestions for the formulation of the route are put forward.
