脱硫废水零排放深度处理工艺研究

Study on Zero-discharge Depth Treatment Technology of Desulfurization Wastewater

脱硫废水含有多种污染物,如COD、SS、氟化物、微量重金属等有害离子,同时具有极高含盐量、极高硬度和极低碱度的特点。根据我国目前针对各种工业废水排放的严格把控和高排放标准的要求,脱硫废水零排放将是未来脱硫废水处理的最终趋势。基于此,本文论述脱硫废水深度处理回用及零排放的新型工艺方法。

Desulfurization wastewater contains many pollutants, such as COD, SS, fluoride, trace heavy metals andother harmful ions. Meanwhile, it has the characteristics of extremely high salt content, high hardness and extremelylow alkalinity. According to the requirements of strict control and high emission standards for the discharge of variousindustrial wastewater at present in our country, the zero discharge of wastewater from desulfurization will be the finaltrend of the future treatment of FGD wastewater. Based on this, this paper discussed the new treatment process ofdeep treatment, reuse and zero emission of FGD wastewater.
