1 Scope
This code specifies the basic requirements of the designing technology for wastewater treatment of thermal power plants.
This code is applicable to the wastewater treatment of newly-constructed thermal power plants, extended thermal power plant and renovated thermal power plant whose turbine generator unit capacity is 125 MW -1000 MW. The design of wastewater treatment of thermal power plants like gas turbine power plant, nuclear power station and garbage incineration power plant whose unit capacity is less than 125 MW may refer to this code.
