2×500MW火力发电厂循环水排污水回用技术分析

Analysis on reuse technology of circulating water blowdown water in 2 × 500 MW thermal power plant

以山西某电厂为例,介绍了循环水排污水经高滤速纤维过滤器、压力式超滤、反渗透处理后作为锅炉补给水水源和热网补水的方案,论述了循环水排污水回用技术的特点,分析了应用后的经济和社会效益,供处理同类问题时参考。

In a power plant in Shanxi,the circulating water blow-down 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.
