Treatment and Effect of Desulfurization Wastewater in Thermal Power Plants
Desulfurization wastewater has always been a difficult problem for various thermal power plants.Although the daily discharge is small,it is extremely harmful.Based on this,a combination of MF-NF full membrane system and electrolysis method is proposed to treat desulfurization wastewater.After microfiltration and nanofiltration treatment,the vast majority of heavy metal ions and a large number of high valence ions can be removed.At the same time,the subsequent electrolysis device generates NaClO fungicides by electrolyzing chlorine,replacing the fungicides that need to be added to the circulating cooling water system,reducing certain production costs and effectively solving the problem of desulfurization wastewater not easily meeting discharge standards.
