燃煤电厂脱硫废水处理技术研究与应用

Treatment Technology and Application of Desulfurization Wastewater Treatment Technology in Coal-fired Power Plants

在煤电厂日常生产过程中,会产生大量成分复杂、污染物含量高的脱硫废水,脱硫废水因其水质、水量不稳定,悬浮物含量高,易沉淀等特点,导致运用常规工业废水处理工艺无法满足废水处理要求。基于对燃煤电厂脱硫废水性质的了解,结合当前广泛应用的脱硫废水处理技术,希望能找到一条稳定高效的脱硫废水“零排放”工艺路线,为燃煤电厂高效发展提供可靠的技术支撑。

In the daily production process of coal-fired power plants,a large number of desulfurization wastewater with complex composition and high pollutant content will be produced.The desulfurization wastewater will be treated with conventional industrial wastewater due to its water quality,unstable water content,high suspended solid content and easy sedimentation.The process cannot meet the wastewater treatment requirements[1].Based on the understanding of the nature of desulfurization wastewater from coal-fired power plants,combined with the currently widely used desulfurization wastewater treatment technology,it is hoped that through this research,a stable and efficient“zero emission”process route for desulfurization wastewater can be found,which provides an analysis of the efficient development of coal-fired power plants.Reliable technical support.
