摘要
石灰石-石膏湿法脱硫是目前火电厂烟气脱硫的主流技术,其产生的脱硫废水具有重金属超标、COD含量高、浊度高、污染性强等特点,因此必须对其进行处理。工程运行结果表明,采用中和、沉淀、混凝、最终中和及污泥脱水等工艺处理后,出水水质达到《污水综合排放标准》(GB 8978—1996)一级标准,满足企业回用要求。
Limestone-gypsum wet desulfurization is the current mainstream technology of flue gas desulfurization in thermal power plant, but the wet desulfurization will produce a certain amount of wastewater in the production process. Due to its characteristics of excessive heavy metals, high COD con- centration, high turbidity and high pollution, the desulfurization wastewater must be treated. The actual operation results of the project showed that after neutralization and sludge dewatering process, the effluent quality could meet grated Wastewater Discharge Standard （GB 8978 -1996）. , precipitation, coagulation, neutralization the first class criteria specified in the Inte-
