What are the treatment methods for traditional laboratory mercury-containing wastewater?
Laboratory mercury-containing wastewater includes organic mercury and inorganic mercury. The traditional method of treating laboratory organic mercury wastewater is to add appropriate oxidants to the wastewater to decompose organic mercury into inorganic mercury and adjust the pH value of the wastewater to 8-10.
Aike wastewater equipment manufacturer specifically equips wastewater treatment equipment with electrochemical oxidation devices to degrade heavy metal wastewater containing mercury, copper, lead and other heavy metal wastewater.
Because the solubility product of mercury sulfide is very small, HS, NaS, and NaHS are commonly used as agents to precipitate mercury. Hg+ and Hg2+ ions are converted into insoluble Hg2S and HgS precipitates.
Since mercury is highly toxic, the filtrate is treated with activated carbon and then filtered and discharged.
