燃煤电厂脱硫废水零排放工艺探讨

Discussion on zero discharge process of desulfurization wastewater in coal-fired power plant

煤炭是我国目前使用最多的化石能源,煤炭燃烧过程中会产生一些污染气体,如SO2等,故需对其进行脱除处理,脱除后的废水中会含有硫的成分,导致污水不能达标排放。本文对脱硫过程中废水的来源进行了分析介绍,并对脱硫后废水的再利用过程进行了阐述,旨在为相关实践提供理论和实践参考。

Coal is the most widely used fossil energy in China. The combustion of coal will produce some polluting gases, such as sulfur dioxide, which need to be further removed. The wastewater after removal will contain sulphur components, which will result in the inability of wastewater discharge to meet the standard. In this paper, the source of wastewater in the desulfurization process was analyzed and introduced, and the reuse process of the desulfurized wastewater was elaborated, aiming to provide theoretical and practical reference for related practice.
