脱硫废水生化处理初探

火电厂烟气脱硫过程产生的废水中污染物主要包括悬浮物、过饱和的亚硫酸盐、硫酸盐以及重金属等，燃煤电厂烟气系统增设脱硝装置后，进入脱硫废水的氨氮、总氮含量急剧增加。通过对国内外多个电厂的脱硫废水处理系统运行情况的调研及分析，采用厌氧氨氧化工艺作为废水脱氮方式是可行的。

Preliminary study on biochemical treatment of desulfurization waste water

The pol utants in the waste water produced in the thermal power plant desulfurization include suspen-ded solids,oversaturated sulfite,sulfate and heavy metals,etc. With the instal ing of denitration device in coal-fired power plant flue gas system,the amount of ammonia nitrogen and total nitrogen in subsequent desulfuriza-tion waste water increase rapidly. Through the investigation and analysis of many power plant desulfurization wastewater treatment systems at home and abroad,we find that using Anammox as the way of waste water denitrification is feasible.
