SDA脱硫系统资源化利用烧结脱硫废水的应用实践

Application of SDA desulphurization system in utilization of sintering desulphurization wastewater

本文分析了石灰/石灰石-石膏湿法脱硫废水的主要特点,对SDA脱硫工艺的技术特点进行研究分析,提出了在SDA脱硫系统中,使用部分湿法脱硫的压滤废水代替工艺水制作脱硫浆液的思路并予以实施,分析了在SDA脱硫系统中资源化利用湿法脱硫废水的可行性,提出了一种消纳湿法脱硫废水的新方法。对同行业有一定借鉴意义。

This paper analyzes the main characteristics of limestone-gypsum wet desulfurization wastewater and studies the technical characteristics of SDA desulfurization,in SDA desulphurization system,the idea of using part of wet desulphurization press filter wastewater instead of process water to make desulphurization slurry is put forward and implemented,the feasibility of utilizing wet desulfurization wastewater as resource in SDA desulphurization system was analyzed,and a new method to eliminate wet desulfurization wastewater was put forward.It has certain reference significance to the same industry.
