脱硫废水零排放技术在清远电厂中的应用探讨

Applicable Discussion of the FGD Waste Water Zero-discharging Treatment Process for QingY uan Power Plant

结合国华清远项目的建厂条件,针对对脱硫废水零排放的蒸馏法、反渗透法和正渗透法三种主要处理工艺,通过对其技术性能和经济成本的综合比较,提出了将反渗透浓缩结晶工艺作为电厂脱硫废水处理工艺首选方案的建议,为电厂下阶段零排放处理工艺选择提供了重要技术支持和参考。

This paper focuses on the three main treatment processes of FGD waste water zero-discharging： distillation treatment, re- verse osmosis treatment ＆ forward osmosis treatment. By mean of comparing their technical performances and costs, combined with the site condition of QingYuan Power Plant the paper recomands reverse osmosis treatment process as the superior option, which pro- vides a piont of view for selection of FGD waste water zero-discharging treatment opitons to the owner in next stage of the projcet.
