Abstract: Abstract:In a power plant in Shanxi, the circulating water blowdown water was treated by the highfiltering velocity fiber filter, the pressure ultrafiltration and the reverse osmosis, and was reused as water source of boiler makeup water and the supplementary water for heat network. The circulating water blowdown water reuse scheme of the plant was introduced. The features of the circulating water blowdown water reuse technology were expounded, and the economic benefit and social effect of the technology were analyzed. The result in this paper can be used as reference for handling with similar problems.
