AN APPROACH TO CONTROLLED ITEMS AND STANDARDS FOR EFFLUENTQUALITY OF DESULFURATION WASTE WATER[J]. Thermal power generation, 2005, (9): 69-71. DOI: 10.19666/j.rlfd.2005.09.019.
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).
