Abstract: In compliance with the requirement for zero wastewater discharge in coal-fired power plants, the quality control technology and drying technology of the terminal wastewater are studied and discussed in this paper in order to properly dispose the terminal wastewater based on the analysis of the wastewater quality and the existing wastewater zero discharge treatment technology. The drying process and its influencing factors of saline drip are researched. After the comparison of atomization and flue gas distribution, the technology of treating terminal wastewater by flue gas bypass drying is finally determined to be applied, and then corresponding engineering application is carried out, which is the first project demonstration project completed in China. Moreover, the engineering effect and operation economy are evaluated.

Key words: coal-fired power plants, terminal effluent, by-pass fule gas drying, demonstration project
