摘要
对脱硫废水所含杂质进行了分析,讨论了应该控制的项目和指标。提出脱硫废水中重金属离子可按照GB8978-1996《污水综合排放标准》进行控制,而化学耗氧量、氟化物和硫酸盐可按下述指标进行控制:COD<150mg/L(脱硫废水处理系统出口),F<30mg/L(脱硫废水处理系统出口),硫酸盐<2000mg/L(电厂总排水口)。
Impurities contained in desulfuration waste water have been analysed, and items and indices to be controlled being discussed. It has been put forward that the heavy metal ions in desulfuration waste water can be controlled according to GB89781996 《Comprehensive effluentquality standard of sewage》, but chemical Oxygen demand (COD), fluoride (F), and sulpfate (S) can be controlled according to the following indices: COD<150mg/L (at outlet of the desulfuration waste water treatment system); F<30 mg/L (also at outlet of the desulfuration waste water treatment system); S<2000mg/L (at overall water discharge outlet of the power plant).
